- date crashed on values resulting in dates before 1970-Jan-1 00:00:00
in the Win32 version. In Win32 now minimum value for date is 86400,
which is safely on or after 1970-Jan-1 00:00:00 for all time zones
- NaN can now be put into a variable for comparison
- division by zero now causes a math exception also in floats (previously
inf was returned in cygwin/Unix version and Win32 crashed)
- in mixed arithmetik using integer operators NaN is taken as 0
6.5.27
- new function 'constant' to protect symbol contents from changing
- fixed bug in newlisp-tk.tcl which was introduced after 6.5.23
which caused problems in Mouse.lsp (_result -> result in 'tk')

list or string
new primitive 'lookup' works like assoc with extracting parameter
fixed bug in pop3.lsp
moved to version 5.4 of Freewrap for making the newlisp-tk.exe, which
is now doubled in size because 5.4 doesn't compress anymore (see Freewrap
docs).
- 7.0.5
Manual improvements in for correct conversion with HTML2DOC
additional hour offset parameter in 'now' and 'date'
fixed bug in dotree which caused crashes on Windows
'context', 'dotree' and 'symbols' now accept unquoted
symbol if the symbols is a context.

The newlisp-tk Windows version is now wrapped with freewrap v.5.5
and based on Tcl/Tk version 8.4.1 and BWidget v.1.6
newlisp-tk.tcl has been changed for better usage of 'context'
- 7.1.0-rc1
PCRE Perl Compatible Regular Expression support updated to version 4.3
in 'replace' now replacement pattern with back references and as
lisp expression. Sub expressions are stored in variable $1, $2 ... etc.
$0 contains the whole pattern found. These variables are also filled
in 'regex' 'find' (all functions doing regular expressions).
The new implementation of 'replace' is also faster (about 15%).
example:
(replace "%([0-9A-F][0-9A-F])" str (char (integer(append "0x" $1))) 1)
This will do URL translation i.e.: "xxx%41xxx%42" -> "xxxAxxxB".
- 7.1.0-rc2
'parse' can take regular expressions in sepearator when additional
options parameter is defined (as in find, replace)
===============================================================================
- 7.1.0 Release August 28, 2003
'search' like 'find' and 'replace' also accepts regular expression
when extra options parameter is given.
[text] and [/text] can be used as string limiters for large text regions
i.e. for HTML in cgi pages written with newLISP. Text limited this way
stays completely unprocessed and contain any characters.
The function 'symbol' accepts unquoted symbol for context parameter
(like 'dotree', 'context', 'symbols')
PCRE Perl Compatible Regular Expression support updated to version 4.4
extensive manual changes formatting and PDF release
- 7.1.1
surpression of some compiler warnings in Mac OSX compile
makefile for linux has strip turned on and readline support
was not the default
- 7.1.2
third parameter in 'symbol' for supression of symbol creation, if
not found; return 'nil instead.
HTML manual had formatting error, which caused all after 'regex'
to be in curier.
===============================================================================
- 7.1.3 release September 3, 2003
[text]...[/text] caused problems in TCP/IP communications
===============================================================================
- 7.1.4 release September 6, 2003
uninitialized memory in writeStreamStr() caused problems when
running newlisp-tk and transferring bigger string buffers.
win32_fprintf() did not work right for buffers > 2048, which
caused problems in browsing bigger buffers in newLISP-tk.
- 7.1.6
new function 'process' for launching independent child processes
(will not block), new function 'pipe' for use with child processes.
'if' now accepts multiple condition-exp pairs and then works like a
cond without parenthesis around condition-value. 'if' with
condition-exp-exp or condition-exp still works like before.
new 'net-send-udp' and 'net-receive-udp' for UDP communications
without need of net-listen,net-accept and net-connect.
On Mac OSX 'import' is now enabled using to addtional files
osx-dlfcn.n/h for compiling. This import is for '.dylib'
libaries.
'append' now also can append binary strings (i.e. containing 0's)
'joint' now also can joint binary strings (including the joint string)
if the length of a sublist in slice is 0 then sice returns the empty
list '(), previously returned nil. This is more consistent with the
behavior of slice on strings and at the end of lists.
'write-buffer' now acepts both: a symbol or a string
'send' now accepts both: a symbol or a string
'symbol' pretended to create a symbol although context would not exist
error messages now include the offending expression/parameter which
caused the error.
- 7.1.7
speedup in UDP communications (no session registration)
memory leak fixed in 'net-receive-udp'
'first' of an empty string now returns an empty string, previously nil
improved cgi.lsp

contexts
- 7.1.12
logfile with string -L options also logs remote command line input
'fft' and 'ifft' now can take plain numbers instead of complex numbers
or a mixture of both
regular expression speedup 5 to 50% by chaching the search pattern
and avoiding recompile, speedup greatly depends on complexity of
pattern relatively to the length of the search string
rearranged functions in source files to make newlisp.c more manageable
eliminated various unecessary typedefs
Sun SOLARIS is now supported (not much tested though)
operating system number in last position of 'sys-info'
linux 1, bsd 2, osx 3, solaris 4, cygwin 5, win32 6

- 7.1.14
redundancy in printString() eliminated
memory leak in 'parse' with regex fixed
the userdefined function for an error is now reported
overall speedup since 7104 of about 5%

- 7.2.1
moved check for symbol type of lambdaFunc to errorProc for efficiency
cleanup of unecessary defines in newlisp.h
defined 'vasprintf()' to take advantage of vasprintf() where available
'format' now checks for correct number of arguments and well formed
format string, it should not crash anymore on mismatch of number
and type of parameters
newLISP-tk is now version 1.0 with changes for multiline 'tk' statements
(stements containing line-breaks), this allows sending bigger Tcl/Tk
code portions in one 'tk' statement
- 7.2.2
force creation of $0, $1 ... in MAIN even when used in different context
for the first time
supress $0, $1 ... in newlisp-tk frontend in variable listbox
(the $ would confuse tk)
- 7.2.3
replace-assoc now also uses the system variable $0 for the old
list, which can be reused in the replacement expression, i.e:
(set 'lst '((a 1)(b 2)(c 3)))
(replace-assoc 'b lst (list 'b (+ 1 (last $0))))
lst => ((a 1)(b 3)(c 3))
replace-nth now also uses the system variable $0 for the old element, i.e:

association found (which is now in $0)
replace-nth now return the changed list instead of the old
expression found (which is now in $0)
now checks also for missing last argument
replace now returns changed list or string
for changed list count of replacements in $0
count for string replacements is not available any more
(could be handled in replacement expression)
now checks also for missing last argument
remove now returns the changed list
and the number of removed elements in $0
- 7.2.5
chop now also works on lists
coding improvements in slice/sublist() and substring()
newlisp-tk 1.02 now on Linux tmp directory is in the home
directory of the user running newlisp-tk
replace with expression in replacement would overflow CPU stack
after 2048 replacements, now no limit
cgi.lsp v.1.2 now lives in a context CGI for better isolation
httpd v.3.0 with bugfixes for big POST buffers
new module infix.lsp for parsing infix expressions
in newlisp-tk changed /tmp to tmp for Linux/UNIX
- 7.2.6
(new CTX 'CTX2) copies context CTX to CTX2, helps using
contexts a objects, which can be instantiated from a template
context
'define' 'constant' used in contexts will always force creation
of the symbol in that context, never overwrite definitions in
MAIN. This is changed behaviour also be reflected in the documentation.
The old way was leading to unexpected definitions in MAIN of symbols
although loaded from a context. 'set' still will first look for a
global in MAIN.
fixed false error messaging on certain parenthesis errors
fixed wrong error message when trying to define protected
symbol
error message 'parameter out of range when calling 'gammai',
'beta' or 'gammaln' with first parameter 0.
- 7.2.7
contexts now can be assigned to variables and referenced
during runtime, i.e. 'contextVar:varName' with late binding
of contextVar. New possibilities of OO programming and lexically
scoped programming, see new chapter in the users manual
about 'Programming with context objects'.
stronger separation of contexts from context MAIN, only
primitive symbols, context symbols, true and nil are
inherited
'new' now returns the new context, formerly 'true'
'set', 'setq', 'set!', 'constant' now return the value of
the symbol set when the rvalue is missing i.e:
(constant 'foo) will make foo a constant and return it's
curent value
protected all symbols in MAIN in newlisp-tk.tcl v 1.03
against accidental overwrite
cleaned up toal mess of tem pdir detection in unix mode
cleaned up init.lsp
'nth' now can take multiple indices, i.e.:
(nth 1 2 0 '(1 (a b (c d)))) => c
good for working with matrices or sparse matrices
out of bounds indices return the last in dimension
'set-nth' like former 'replace-nth' but multidimensional
like 'nth'
(set-nth 1 2 0 '(1 (a b (c d))) 'x) => (1 (a b (x d)))
- 7.2.8
eliminated statics in lambda expression, not necessary
anymore as we have dynamic contexts, which also
create a lexically closure around vars
fix in dolist, how cleanup is done
===============================================================================
- 7.3.0 Released version 2003/11/03

in str with category option int as speicied in "locale.h" of
platform/OS, look for defs of LC_ALL, LC_NUNMERIC etc..
on startup newLISP tries to swithc to ISO "C" locale.

and define, define-macro; loop variables in dotimes, for, dolist
and dotree are protected against change by user with an error
message during looping and may not be constant before the looping
starts using them

doc changes for 'net-receive-udp'
'net-receive-udp' can now receive on a specific IP address, this
was documented already but not working
'net-connect' and 'net-listen' ca use a "udp" option to do

more tweaks in qa file
fixed potential memory leak in 'new'
- 8.2.0 Release September 21st, 2004 ======================================
- 8.2.1
write-buffer can now take string instead of file handle to write
to a string in a string growing (concatenating) fashion, this is
much faster then doing (set 'str (append str content)) now:
(write-buffer str content)
'symbol' now can overwrite global symbols from MAIN (i.e. built-ins)
i.e. (symbol "print" 'MyContext)
'process' now ca take to addtioal pipe handle parameters, which
get mapped to stdin and stdout for the new process:
(map '(myin bcout) (pipe))
(map '(bcin myout) (pipe))
(process "bc" bcin bcout)
(write-buffer myout "3 + 4\n")
(read-line myin) => "7"
'semaphore' lets you create wait and signal semaphores
(set 'sid (semaphore)) ; aquire
(semaphore sid -1) ; wait
(semaphore sid 1) ; signal
(semaphore sid) => 1 ; status
(semaphore sid 0) ; release/delete
'share' to create shared memrory regions
(share) => address off mmap share
(share addr exp) => sets addr to exp for integers, floats and strings
(share addr) => returns integer, float or string exp
added newLISP-Excel-Import.xls example to examples/ directory
added prodcons.lsp - demo for fork, wait-pid, semaphore and share
- 8.2.2
'write-line' with string device like 'write-buffer', in both
symbol is now protected if protected with constant
share was broken for strings
- 8.2.3
pipe is now also available on CGWIN and Borland compiled versions
on all Win32 versions pipe can now remap std I/O like on Linux/UNIX:
(map '(myin bcout) (pipe))
(map '(bcin myout) (pipe))
(process "bc" bcin bcout)
(write-buffer myout "3 + 4\n")
(read-line myin) => "7"
process on Win32 can hide or minimize window:
(process application 0 0 0) => hide app
(process application 0 0 1) => show app
(process application 0 0 2) => minimize app
'share' and 'semaphore' are now also available on Win32
improvements in qa file, now tests all functions by default w/o ext option
better syncronization on some tests with semaphores
'match' in list mode now only returns matched expressions
(map set '(x y) (match '(a (? c) d *) '(a (b c) d e f)))
x => b
y => (e f)
when using match with an optional third parameter 'true', it works
in the old fashion: (map pattern aList true) => works like before
The context default function is a userdefined function with the same name
as the context it resides in, i.e: (define (ctx:ctx a b) (+ a b)) and can
be called just with the context name (ctx 3 4) => 7.
Default functions should only be called rom MAIN, or have already been
loaded or their context created before referred to in another context or
default function. Not yet 'official' see doc/default_functions.html
fixed cell leak in 'match' on backtracking
bug fix in let which did not honor protected symbols
- 8.2.4
deprecated collect, getenv, putenv and environ completely eliminated from
newlisp and examples, modules: httpd, cgi.lsp, sqlite.lsp
'+' new wildcard operator 'match': take one or more
net-error now returns error number and text separate in a list
net-connect failure did not set net-error
'now' has now the daylight-savings-flag 0 or 1 as last parameter
new 'sys-error' for reporting C-library errno values
'newlisp -e' without a command string crashed
'push' now optimized when pushing as last element with -1
(new ...) now will not overwrite existing symbols, to allow true
mixins of other contexts. To overwrite symbols as before version
8.2.4 use the true as a third parameter i.e. (new A 'B true).
- 8.2.5
'symbol?' can now be used on dymamic context vars, i.e
(set 'ctx MyCTX) ; MyCTX is existing context
(symbol? 'ctx:x) ; true if MyCTX:x exists, nil if not
This checks the xistence without inadvertantly creating it.
previously (symbol "x" ctx nil) had to be used.
'replace' can now take an additional option bit 0x8000 for replacing
only once in a string: (replace "a" "aaa" "A" 0x8000) => "Aaa"
'define-new' copies individual funtions from
other contexts with or without renaming them to a new function:.
(define-new 'foo:func 'bar:func) copy to different context
(define-new 'foo:func 'foofa) copy to current and rename
forward referece to a symbol in symbol did not work in mixin mode
of 'new'
the space between optioncharacter (-s,-m,-p,-d,-e) and optionvalue
can now be omitted, i.e. -s 10000 and -s10000, both work.
'date' without an argument returns the character string for the current
local time, this avoids the construct (date (apply date-value (now)))
'date-value' without and argument returns the time of seconds
since 1970-1-1 0:00 equivalent to (apply date-value (now))
8.2.6
'delete' now can delete an entire context without removing conatined
symbols first
serialization of contexts to a file using 'save' now is done correctly
when the context context contains overwrites of global symbols.
a more flexible and faster 'symbol' function, which can take any character
sequence and numbers, and can be used this way for hash-like associative
memory access. New module hash.lsp to show usage.
'define-new' renamed to 'def-new', for shorter typing and for not
associating it to 'define' but rather to 'new' (was introduced in 8.2.5)
'letn' works similar to 'let' but incrementally uses the local variable
bindings like multiple nested let when evaluating the initializer expressionsi
for locals.
8.2.7
'address' (previously only documented in 'hacking_newlisp.html') now also
returns addresses to integer and double float data type, useful when passing
int * or double * to imported functions, now documented in main manual
'sym' is an abbreviated form of 'symbol', since 'symbol' starting in 8.2.6
can take any sequence of characters, including strings which are illegal
symbols in newLISP syntax, and is used for hash/dictionat like lookups, it
is used more often, therefore this shorter form 'sym' is introduced
added configuration variable in newlisp-tk.config to specify a newLISP
application. See newlisp-tk.html "Delievering Applications" for details
'apply' and 'map' now can be used on macros
'pack' and 'unpack' have new format specifier 'b' for unsigned 8bit numbers
'encrypt' crashed on empty strins in key
8.2.8
'encrypt' crashed on empty key-string, now gives error message
'int' as shorter writing of 'integer'
'pack' now converts all types as needed, i.e. (unpack "b" (pack "b" -1.0)) => 255
from-to integer-floats, did it before only for "f" and "lf"
'flt' converts a number to a 32bit float repesented by an integer for usage
in calling imported library routines, which take floats.
'array' skipped wrong index types instead of giving error message
8.3.0 Released Nov 21st, 2004
8.3.1 Released Nov 23rd, 2004 ============================================
'nth-set' gave error on protected symbol in index
'apply' 'map' on macro was returned to 8.2.0 behaviour
8.3.2
more cleanup in qa file
cleaned up makefiles -D definitions eliminating redundant -DOPSYS
eliminated 'break', which did not do anything after introduction
of 'debug' in version 6.3.07
overall speedup of about 5% by predefining system symbols
$0 -> $15, speedup of 80% to 100% in functions using system
symbols like set-nth, nth-set, find, parse, regex, replace
new 'do-while' and 'do-until' check condition _after_ evaluating
the body expressions
new 'read-key' reads nonblocking keyboard character code
not working on Mac OSX but all other flavors
superflous args in user defined function call caused cell leak
never happened, i.e.: (define (foo x) ..) and (foo a b c)
'get-url' now handles "Transfer-Encoding: chunked" correctly
'amb' picks an argument at random and evaluates it
-x command line switch for server mode with handler function
'x-event' i.e: newlisp my-httpd -x 8080
my-httpd is a lisp file containing the user defined handler
function i.e: (define (x-event request) .....)
this way servers for different protocols / requests can be simply
programmed using 'print','read-line', etc., for IO to the specified
port, the connection stays up until closed by the client.
See chapter 'Command line options ...' in the manual
fixed a bug in 'new' and 'def-new' when the source was MAIN
this fix was necessary to write a function (def-static ....)
for writing statically scoped functions (see int the manual
chapter 'Lexical, static scoping in newLISP', subchapter
of 'Programming with context objects'.
8.3.3
'debug' did not handle default functions written without colon
'save' 'source' did not space symbols under sum circumstances
'dolist' now double as fast and safe to break out with 'throw'
'catch' now has an additional syntax with just one argument to write
easier returns from functions, loops or blocks, ie:
(catch (dotimes (x 1000) (if (x 500) (throw "fin"))) => "fin"
returns the result or throw argument
8.3.4
'save' 'source' spacing-fix was incomplete
8.3.5
If the a '!' is entered as the first character on the command line immediately
followed y a shell command, that command will be executed, i.e. !lsi in Unix
or !dir in Win32 would show a directory listing. There should be no space
between '!' and the shell command.
URL length in get-url and post-url is now unlimited
8.3.6
manual corrections, additions and new sub-chapter about XML-RPC
BASE64 encoding and decoding with 'base64-enc' and 'base64-dec'.
new sign-on message, and different for remote modes
added 'xmlrpc-server' to examples directory
added 'xmlrpc-client.lsp' to modules directory
fix for 'Transfer-encoding: chunked' if 'Content-length:'
is given too (which should not happen but is found occasionally)
8.4.0 Released 2005-01-18 ============================================
added xmlrpc.cgi for handling XML-RPC requests as CGI
fixed a file descriptor leak in -d -x modes
after the 'debug' fix in 8.3.3 debug did not recurse into funcs
'args' can take an index argment i.e. (args 0) (args 1) etc.
8.4.1
fixed signon message missing 'n'ewLISP
added UTF-8 to signon message
added f-prob to stat.lsp (probability of F ratio for df1/def2)
(throw-error expr) throws an error with message printed in expr
error thrown this way can be handled like any other newLISP error
using (catch foo 'result) or with (error-event ...)
changed/added docs for catch, throw, throw-error and chapter:
Integer abnd Floating point ...
newlisp-tk.exe now wrapped with freewrap v.6.0 and Tcl/Tk 8.4.8
suppresses occasional display of tcwish console
added updated newlisp.jsf syntax file for JOE editor to distribution
8.4.2
[cmd] tags did not work when compiled with READLINE option
(args) which previously worked only in macros now too works in
functions. The behaviour of (args) has changed: only unbound arguments
for which there is now local variable in the macro (or function) are
returned in the list. This makes changes in existing macros necessary,
which specify both, local variables and they use args. Most changes
lead to simpler macros or function, because (args) already contains
only the unassigned args.
changed macro definition of 'tk' in newlisp-tk.tcl to function
changed plot 'macro' in stat.lsp and 'defun' in init.lsp
8.4.3 Release 2005-02-12 =================================================
cleanup from (args) changes, protect $args from deletion
8.4.4
misplaced paren in conditional def of defun in init.lsp
OS number in sys-info was incrementing on every call when DLL or UTF-8
decimal point setting from locale is now used correctly when parsing source
i.e. after performing (set-locale "German_Germany.1252") in Germany
1,23 will be recognized corectly as a decimal number with comma as the
decimal separator.
qa_comma QA test file for German or other locales using ',' comma as
decimal separator, qa renamed to qa_dot for decimal-dot locales.
In comma locales both, qa_dot and qa_comma should work, in decimal
dot countries onlz qa_dot will work.
daylights savings field in 'now' function now shows a flag 1/0 if time
zone may have DST at certain time of the year on Linux/UNIX. On Win32
it shows a 'daylight minutes bias' for timezones which may have DST.
Note that flag/bias is set through all the year even if DST is not
in effect at a given moment. May not work on all platforms.
additional format parameter in (date num offset fmt), see GNU gcc
strftime() function for details
Win32 installation now to $PROGRAMFILES/newlisp, which is
c:\Program Files\newlisp on English Windows. This defines a
fixed location for $PROGRAMFILES/newlisp/newlisp.dll for applications
loading newlisp.dll. 'PROGRAMFILES' is an environment variable available
on all MS Windows installations.
newLISP is now correctly registered in the
'control panel/add or remove programs' applet
8.4.5
newlisp.exe compiled on MinGW or Borland now will look for init.lsp
in the same directory where newlisp.exe resides
installer now sets path on Win32, this allows to import the DLL without
specifying the full path and allows to start newlisp or newlisp-tk from
anywhere on Win32
installer now allows installing without newlisp-tk
'nth' upgraded to 16 indices (like set-nth and nth-set)
'sort' now allows any binary operator user defined function as
compare funtion in third parameter
'implicit indexing' on lists, arrays and strings i.e.:
(lst 1 3) equivalent to (nth 1 3 lst)
(ary 0 -1) equivalent to (nth 0 -1 ary)
("newLISP" 3) equivalent to (nth 3 "newLISP")
unlimited number of indices and faster than explicit form
'pack' and 'unpack' now allow switching between little and big endian
byte order using new format characters '<' and '>'
8.4.6
'new' and 'def-new' did not replicate arrays, could cause crash
8.4.7
added 'upload.htm', 'uplload.cgi' to examples directory
minor fix in xmlrpc.cgi xmlrpc-server
better handling of bad server responses in get/post/put-url avoiding
an ifinite loop on some types of bad server responses
fix for endian switch in 'unpack' which changed the original buffer
re-arranged arrays, hashes and indexing chapters in the manual and
enhanced hashing chapter, added Win32 trailing slash warning to
manual entries of 'directory' and 'directory?'
experimental implicit indexing with nrest:
(1 '(a b c)) => (b c)
(1 "abc") => "bc"
8.4.8
implicit indexing with slice:
(3 2 '(a b c d e f g)) => (d e)
(-4 2 "abcdefg") => "de"
updated infix.lsp to version 1.4/5 was broken after newLISP 8.2.0
because of change in 'symbol' functioanality
possibility to check legality of a string as a newLISP source symbol
with (symbol? string), i.e: (symbol? "a b") => nil
illegal symbols are now serialized correctly in 'save' using a
set expression with (sym str context)
the Win32 installer now will correctly change settings in
newlisp-tk.config when chaning the install path during installation
will only work Windows 2000 and later
8.4.9
did not evaluate length in implicit slice-length
8.4.10
separated legal symbol? functionality into 'legal?' function. 'symbol?'
back to pre 8.4.8 functionality
8.5.0 Released April 8, 2005
'=' fixed problem when comparing strings and binary buffers
'args' with negative index did hang
'main-args' nor can be indexed like args, both accept negative indices
8.5.1
newlisp-tk tripped over file spec "", changed to "." in lastLoadedFile
on MacOSX. Changed Demo.lsp to work with TLCKAqua on MacOSX.
new function 'factor' for factoring numbers up to 15 digits
(must give floats for numbers bigger max int)
in newlisp.so and newlisp.dll main-args was initilized to nil instead of
the empty list ()
list in 'dolist' now safe to modify (back to 8.3.2 behaviour), but can
leave with 'throw' without leaking cells
signalling SIGUSR1 will perform a 'reset' but not kill newLISP
'timer' start a one shot timer event and registers a user defined
event handler, i.e: (define (ticker) (println (date)) (timer 'ticker 1))
defines a self starting and retriggering ticker.
8.5.2
added debug option to SIGINT handler, eliminated SIGUSR1 handler, because
is redundant
8.5.3
added 'signal' for userdefined signal handlers: (signal sig-no symbol)
args was not reset to '() when left unused in recursion levels
8.5.4
signal handler can pass the signal number as an argument (see manual)
new makefiles for OSX/Darwin UTF-8: make 'osx_utf8' and make 'darwin_osx_utf8'
(Darwin means: OSX + readline support)
when compiled with readline support newLISP will now exit pressing Ctrl-D
(Linux/UNIX)
'net-select' crashed on an empty list
8.5.5
fixed UTF-8 problems in file names in newlisp-tk.tcl (thanks Norman)
UTF-8 symbols where not treated as legal symbols in 'save' , 'legal?'
This prevented UTF-8 symbols to show up in the editor/browser listbox.
This is now fine on all UTF-8 and non-UTF-8 version.
UTF-8 now handled correctly in hostnames in net-xxx routines
UTF-8 now handled correctly in 'float' and 'integer', took some
UTF-8 characters for numbers.

portnumbers/sockets
sqlite3.lsp v.1.3 now handles FLOAT and BLOB datatypes and finds the correct
library/location depending on the OS platform

version newLISP-tk 1.26 now works correctly when installing on MacOSX
use 'sudo make install' after build with 'make darwin' or 'make osx'
needs TclTk Aqua installed with darwin port tools
8.5.6
fixed potential problem in 'net-connect' with multicast option on
big-endian CPUs (MacOSX)
added broadcast option to 'net-connect' as udp mode plus broadcast specified
with "b" or "broadcast" instead od "udp". Broadcast mode was already possible
in 'net-send-udp'. Now broadcast can be set up in non-blocking mode on the
receiver side.
8.5.7
big speedup of 'replace' with strings on a file of 100k about 30x on
500k about 500x times speedup.

share on Win32 leaked memory
8.6.1
'sql3:open' now returns nil and sets error the message when trying
to sql3:open twice.
'timer' now returns the elapsed time when calling just with the
event symbol, useful for checking timer progress or programming
timelines/schedules.
'source' now works like 'save' and can take multiple symbols;
context symbols are serialized including all of the contained
symbols.
Files are now created without execution permission with rw-rw-rw
which results in rw-r--r-- on UNIX systems assuming a user mask
of 0022.
'peek' similar to 'net-peek' but for any file descriptor, returns
number of bytes ready to read works also on std I/O 0/1. Only UNIX.
Added gmp.lsp for GNU Multi Precision library, contains
integer functions for arithmetik, see header of file gmp.lsp
for details.
optional parameter 'true' in 'difference' and 'intersect' puts
these functions in list-mode (versus normally set-mode).
new function 'title-case' upper-cases first character and
optionally lowercases the rest characters
8.6.2
changed makefile_darwin_utf8 to work on standard 10.4 installation
a parameter in utf8 version of upper/lower was evaluated twice
caused by new title-case code in 8.6.1
fixed append mode in file 'open' which created file with ------
permissions when file did not exists
optional 'true' flag in net-lookup to force hostbyname() lookup
for strings like "216.16.84.66.sbl-xbl.spamhaus.org"
huge speedup for 'difference' and 'intersect'. On a 10000 elment
list about 100 times speedup, both functions now scale linearly
with n+m instead of n*m, when n an m are the lenghts of the two
lists
speedup of 'count' for big item lists now scales m+n instead m*n
when m is the list of items to count in list with length n
8.6.3
'difference' did sometimes not unique, 'nil' treated incorrectly
8.6.4
fixed problems in 'count' and 'sort' caused by changes in 'sort'
necessary in new version of 'count', 'difference', 'intersect' and
'unique'
8.6.5
'catch' did not respect protection of symbols in the catch symbol
make version with sed finally working on UNIX previously only
cygwin
new function 'randomize' shuffles the elements of a list
new function 'net-eval' evaluates a batch of functions remotely
on newlisp servers, manages Tcp/Ip communications and data collection
with multiple servers started with: newlisp -c -d <portno>
timeout and optional callback/idle function
'array' with 0 length dimension crashed, now ignores 0-length
-d mode would exit when loss of communication in multiline [cmd] mode
now just cycles to restart
'error-event' only worked in programs loaded interactively, now works
also defined in scripts started on the command line
-l and -L now usable for logging in normal console mode, -l logs only
user input -L logs both user input and newLISP output (without prompt)
new chapter for logging in users manual
when evaluating multiple expressions on the command line or a batch
of expressions enclosed in [cmd],[/cmd] tags multiple results are now
separated by one space.
8.6.5-7
'ramdomize' looped on listlen 1
'load' now throws an eror when the file cannot be found or returns
the value of the last expression in the file evaluated. Before 'load'
returned 'nil' when file was not found and else 'true'. Note that this
required a change in init.lsp to catch error when trying to load
$HOME/.init.lsp
eliminated all sprintf() to avoid security warnings on openBSD compiles
'erf' and 'sgn' new functions

push/pop and implicit indexing)
8.7.2 development Release November 20th
new (net-ping host wait-time) returns ip-no or multiple ip-no for multiple
addresses in batch-mode or broadcast. Must have root privileges to use, or
set the newlisp executable set-user-ID with: chmod u+s /usr/bin/newlisp or:
chmod 4755 /usr/bin/newlisp; only on UNIX
'time' now safe for midnight wrap
'dup' with optional 'true' flag now can force list return when a string argument
is given; by default 'dup' concatenates the string

details
moved 'prob-chi2' and 'pob-z' in manual to "Simulation and modelling" group
together with 'bayes-train' and 'bayes-query'
ATTENTION:
calling into a context now changes the current run-time context:
(context 'FOO)
(define (foo) (context))
(context MAIN)
(FOO:foo) => MAIN ; old behaviour
(FOO:foo) => FOO ; new behaviour
The new behaviour is more intuitive and is what most programmers would expect.
Only applications using 'eval-string' or 'sym' (w/o specifying a context) are
effected. From all apps published by newlisp.org (blog, wiki, ide) only the file
cgi.lsp packaged with these applications is affected and should be changed to
the new cgi.lsp v.1.9 packaged with 8.7.8.
Users should check all applications using 'eval-string' and 'sym' (or the
deprecated 'symbol'). Pre 8.7.8 'eval-string' and 'sym' work with the runtime-
context beeing MAIN, the context where the program was started. Now both functions
work with the context they are part of:
(context 'FOO)
(set 'x 999)
(define (foo s) (eval-string s))
(define (bar s) (eval (sym s)))
(context MAIN)
(set 'x 123)
(FOO:foo "x") => 123 ; old behaviour
(FOO:bar "x") => 123 ; old behaviour
(FOO:foo "x") => 999 ; new behaviour
(FOO:bar "x") => 999 ; new behaviour
Changes to old code:
(1) Replace all cgi.lsp in newlisp-ide, newlisp-blog and newlisp-wiki apps.
the replacement will also work with newLISP versions previous to 8.7.8.
(2) Change old apps by preceding the 'eval-string' statement with (context MAIN)
or other required context change. Most of the time it's MAIN, the context where
th whole program was started.
(3) Change old apps adding explicitly the desired context in 'sym' as a
second parameter, i.e. (sym s 'MAIN) or (sym s ctx) where 'ctx' is a context
variable.
The new behaviour is more intuitive and will make OO based programming based
on contexts easier, it also increases isoloation of contexts because the current
run-time context is not dependend from where the program was started originally,
but only on the situation internal to that context.
8.7.9
added a configure script for compatibility with the popular autoconf/configure
system. An installation of autoconf is not required but the same sequence
of commands as on autoconf systems will work to make newLISP. newLISP's old
ways of making newLISP will also still work:
./configure will just try to discover the platform and give a message
make will try to discover the platform and make it
if make cannot discover the platform it will give a message
the module/context is now reported in error messages
'load' will never cause the runtime context changed, but the same run-time
context that was valid before the call to 'load' will be valid when 'load'
returns
'eval-string' now can specify the context under which it's string argument
should be parsed and evaluated.
'log' can be specify an additional parameter for a different base than the
default natural log
fixed a problem with reading very long UTF-8 source string constants
big speedup of parse with regular expression, now scaling linear
this enables tokenizing big documents in one piece
args in functions should be evaluated in callers context
(for: sym, context, eval-string)
8.7.10
raw string ouput (upper ascii in \nnn codes) in the newLISP commandline shell
return value only when locale is the default "C" locale.
'trim' was changing the original string in UTF-8 mode
'find', 'replace' and 'search' now do binary in both regex and non-regex modes
searched buffer, key/patterns string and replacement string can all contain
binary 0s
8.7.11
'string' now optimized double fast on string arguments
getCreateContext() checking symbol protection
'load' switches to context MAIN when loading file except if different
context is specified in file, on return 'load' switches back to callers
context (8.7.9)
'reset' adds an additional parameter for restarting newLISP with same
command line parameters with fresh memory in a new process space.
many security improvements for OpenBSD compiles
'reset' with optional 'true' (or non 'nil') parameter will restart
newLISP with the same commandline parameters, reloading files etc.
Not available on Win32 (execv() leave the system unstable when compiling
with MinGW.
8.8.0-p1 pre-release 1
'reset' was always exiting on UNIX after the change in 8.7.11
text buffers returned in 'net-eval' > 2048 characters and containing zero
characters where throwing a 'string too long error'
8.8.0-p2 pre-rlease 2
Many doc corrections
system symbols in set-nth was broken in 8.7.6
self refs in set-nth now safe
added and changed some cases to qa_dot and qa_comma, now safe again
for memory leak tests.
8.8.0 released February 20th, 2006
large file system support for files > 2 GB can now be turned on in newlisp.h
specifying #define LFS. File positions > 2^31 must then be specified as
floats up to 999999999999999.0 for 999 terabyte (TB). 'seek' will always
return a float, file positions should be handled as floats using
add, sub, mul, div instead +,-,*,/
Documentation corrections (thanks Ryon, Nigel et al.)
moved sql.c and types.c into the util directory
updated newlisp.vim (v1.27) and newlisp.jsf (v.1.9)
bug fix in cgi.lsp for '=' in key value strings
8.8.1
realloc compiler warning fix in nl-filesys.c/readBuffer()
error-event, net-eval (edited 4/13/20060), signal and timer can now take
a function or lambda expression, previously only a symbol holding a lambda:
(signal 2 exit)
(timer (fn () (println "hello")) 5)
The old syntax still works too.
Could not compile to a library (also fixed in re-release of 8.8.0)
code cleanup for allocMemory() + memset() => callocMemory()
now memory cleanup after exception in functor passed by:
'filter', 'index', 'net-eval' and 'replace'.
implicit n-rest and slice on default lists and strings:
(set 'foo:foo '(a s d f g h j))
(2 foo) => (d f g h j)
(-3 2 foo) => (g h)
'save' and 'source' will always serialize from context MAIN perspective
(like 'load') (source reverted back in 8.8.2)
fixed odd/even problem for 'rand' on FreeBSD, NetBSD, OpenBSD
8.8.2
'source' reverted back to 8.8.0 behaviour: serialize to current context
8.8.3
'signal' fixed format of internal symbol when passing functions
suppress saving/sourcing system symbols starting with '$' unless specified
specifically
new built-in function 'real-path' translates a relative path into an
absolute path. (read-path) same as (real-path ".") returns the current
working directory
8.8.4
'real-path' now also in Win32
handle self reference of result of while expression in condition
allow (sys-info 3) or (sys-info -1) as with 'args' and 'main-args'
'dup' will assume 0 for negative values
when entering multiline expressions/definitions bracketed by [cmd] ... [/cmd]
tags (each on a separate line] and hitting <enter><up-arrow> after the closing
[/cmd], newLISP compiled with lib readline support segfaulted, this long standing
bug as finallly been fixed
in 'xml-parse' when a closing CDATA tag was preceded by a forward slash, then
an extra text element containing part of the closing tag was emmitted,
this is fixed
support for MySQL v. 5.0 was added with mysql5.lsp
8.8.5
'read-key' now also works on MacOS X
a bug in the second syntax of 'context' has been fixed now can do:
(push i (context 'CTX "foo")) which now works if CTX:foo is a list
'load' now can take http:// (and file://) URL prefixes in filnames to retrieve/load
files via HTTP from remote servers
'xml-parse' now can take a context to place symbols/tags from SXML conversion
zlib.lsp: new module for in memory and .gz compatible file compression
'net-eval' idle loop did not pass parameter (broken in 8.8.1)
fixed a cell leak caused by 'while' self ref handling in 8.8.4
8.8.6
fix for error reporting of strings, which are too long
an optional break condition in all looping constructs allows early return:
(for (i from to step condition) ...)
(dotimes (i N condition) ...)
(dolist (i lst conditon) ...)
When condition returns non-nil the loop returns with the value of the condition.
When loop comes to end end the result of the last body expression gets returned.
describing the effects of non-rectangular matrices in the "Data types" chapter
and for the functions 'multiply', 'invert' and 'transpose'.
sqlite.lsp vor SQLite v.2.x has been discontinued, use sqlite3.lsp and SQLite3
error message was printed for each catch level where error was not caught,
should only be printed on top level if uncatched
new 'letex': let expression with expansion of let vars into body expressions
before evaluation
file open for append now atomic
8.8.7
new 'clean':
(clean predicate? aList) works like:
(filter (fn (x) (not (predicate? x))) aList)
"Transfer-Encoding: chunked" did not trigger chunked decoding
when more than one space after the ':' before 'chunked'
$0 counter did not count first element when in remove mode of
'replace'
'unify' does Prolog like unification with occur-check
(unify '(f (g A) A) '(f B xyz)) => ((B (g xyz)) (A xyz))
'unify' can take additional assoc params list:
(unify '(A (B) X) '(A (A) Z) '((A 1) (Z 4)))
=> ((A 1) (Z 4) (B 1) (X 4))
this is useful when chanining/nesting 'unify' to pass on
a newly bound environment
new mode in 'expand' with parameter assoc list:
(expand '(a (B (c) (d a B))) '((a 1) (B 2) (c 3) (d 4))) =>
(1 (2 (3) (4 1 2)))
new mode in 'expand' without symbol or assoc list:
(set 'X 2)
(expand '(a ((X)) b)) => (a ((2)) b))
expands only uppercase variables for use with the new Prolog like
'unify' function
added file syntax.cgi for syntax highlighting in HTML of newLISP source
to examples directory
8.8.8
eliminates several cell leaks in unify
'pop' can be used on strings (pop str [pos] [len]) pos can be negative
'push' can be used on strings (push str [pos]) pos can be negative
'push' now will only do list mode when lst is list or nil:
(push new lst) lst has to be list or nil, previous to string mode of push
any existing datatype non-list was initializeed to () now only nil is allowed
system var $idx contains the offset in dolist:
(dolist (e '(a b c d e)) (println $idx "->" e))
0->a
1->b etc.
indexing mode of 'args' now works with multiple indices, i.e (args 3 -1)
and is much faster
implicit indexing syntax now allowed in 'nth-set' and 'set-nth':
(set 'd '(a b c d e f g))
(nth-set (d 3) 99) => d
d => (a b c 99 e f g)
or with default functor:
(set 'db:db '(a b c d e f g))
(nth-set (db -1) 99) => g
db:db => (a b c d e f 99)
This also works for strings and arrays
many fixes/changes/additions in the manual and reference
8.8.9
'net-ping' didn't work on localhost
'nth-set/nth-set' bugfix for new feature breaking old
complete manual pass of the first 3 chapters by Michael - thanks

allow 0 length in chunked pages happening on put-url
give error message for unterminated [text] in interactive console
8.9.0 Release June 25th
complete pass through Users Manual by Michael Michaels
example programs in Appendix are now syntax highlighted
dolist $idx safe for nested loops
member works for strings
(starts-with s k true) should behave like the default (starts-with s k)
same with ends-with. This bug never surfaced because nobody specified
anything for the default of case sensitivity
8.9.1
(rand x n) returned n+1 after fix in 8.9.0, also looped on n=-1
new 'zero?' was broken for floats with fractional parts
newlisp -c -d <portno> and newlisp -c controlled by inetd now understand
simple HTTP GET requests. This feature is mainly intended for use with
(get-url "http://...) and (load "http://...) for retrieving or loading
files from remote newlisp/inetd worker nodes in a distributed computing
environment.
manual reviewed/edited up to and including the letter C
8.9.2
new (find-all pattern string [func [options]]) finds all regex-patterns in a
string and returns a list of matching strings:
(find-all {\d+} "asdf2kjh44hgfhgf890")
=> ("2" "44" "890")
(find-all {(new)(lisp)} "newLISPisNEWLISP" (append $2 $1) 1)
=> ("LISPnew" "LISPNEW")
the parameters in 'format' after the format string can now also be
given in a list: (format "%d %s" '(123 "hello"))
'read-key' did not work on SUSE Linux
8.9.3
default values in function and macro parameters: (define (foo (a 1) (b 2)) (list a b))
(foo) => (1 2)
(foo 3) => (3 2)
(foo 3 4) => (3 4)
no performance loss for normal syntax without defaults
format partly rewritten for better portability,
no tru64.c or ffi required after removing TRU64 for p_format in nl-string.c
8.9.4
removed tru64.c and changed makefile_true64
starts-with and ends-with can do reguluar expressions and take a regex option number,
the old nil-option for case insensitivity still works and is translated to regex
option = 1, but is deprecated and will be eliminated in the future
member for strings can take regular expressions, the old case insensitivity option
will not work (member for strings was introduced only recently
'symbol' the old writing for 'sym' has been eliminated
fixed create context bug in newlisp-tk.tcl
(<< num) works like (<< num 1), (>> num) like (>> num 1), (div num) like (div 1.0 num)
function 'uuid' for creating Universal Unique IDs type 1 and 4 (RFC 4122)
-C command option for Emacs forces prompt even if in pipe mode
manual edits up to letter J, thanks Michael
8.9.5
type 4 UUID now closer to RFC 4122 specification
trying to use set-nth or nth-set on an empty list corrupted the list
8.9.6
UUID type 1 got timestamp wrong, UUID 4 always started the same sequence
-------------------------- 64 Bit Integers ------------------------------------
8.9.7
all integer arithmetik 64 bit
'factor' now takes integers with max 64 bits and is 4x faster than previously
'import', 'pack', still take ints as 32bit, taking the least significant 32 bits
to pack 64bits do: (pack "ldld" int64 (>> int64 32)) for little endian
for big endian do: (pack "ldls" (>> int64 32) int64)
'format' has new 64 bit formats "%lld", "%llu" "%llx" for 64bit decimals and
hex numbers on UNIX on Win32 use "%I64d", "%I64u", "%I64x"
'format' now also recognises 'e' and 'E' scientific folating point formatting
32 bit format strings "%d" "%u" "%x" will truncate on int64 numbers
in float->int conversions floats out of range are converted to min/max 64 bit int
-9223372036854775808, 9223372036854775807 and 18446744073709551615 for unsigned
if an int32/uint32 is required by a function int64 values overflow to
min/max 32 bit int -2147483648/2147483647 and 4294967295 for unsignde int
LFS (large file support) in file operations for files opened with 'open'
now full 64 Bits (before 40 Bits)
(for (i from to step)...) has float in i, only when optional step value is specified
(sequence from to step) produces float only when optional step value is specified
(dotimes (i N)...) always has integer in i
this is consistend with 'inc' and 'dec'
net-select now can go to 68 :) years waiting time specifying 64bit higher timeout
values and a timeout of -1 waits forever
'net-close' with optional parameter: (net-close sock true) will suppress shutdown()
before closing the socket. In this case net-close will wait for undergoing traffic
to finish
new function (gcd x y ...) for greatest common deviser of n arguments
(pow x) defaults to (pow x 2)
wrong format could segfault (this bug was introduced in 8.9.3)
when replacing the first element in an association list with 'replace-assoc' and
an error occured when evaluating the replacement expression a segfault occured
(thanks to Ingo for catching this)
Note that bits shifts <<,>> now work on 64-bit integers too (added 2006-09-12)
8.9.8
'net-eval' now evaluates node parameters, before constants where required
(set 'host "localhost" 'port 4711 'cmd "(+ 3 4)")
(net-eval '((host port cmd)) 1000) = (7)
'net-eval' if no timeout specified waits forever
'net-eval' short form for one node: (net-eval host port cmd [timeout idle-loop])
timeout an idle loop are optional: (net-eval host port cmd)
Similar as for (load "http:// ...) and (get-url "http//..) in 8.9.1;
server mode: newlisp -c with -p or -d, now understands HTTP PUT requests
for saving/writing text files to a newLISP server node on UNIX using:
(save "http://..." ...) and (put-url "http://...") ...)
The server mode together with the beefed up 'net-eval', 'load', 'save'
'get-url' and 'put-url' assemble a nice toolset for distributed applications
with newLISP. The server node can also be started by inetd or xinetd.
(See manual). Must give full path-file-name in URLs i.e:
(put-url "http://localhost:50001//Myfiles/afile.txt" (read-file "somefile"))
newLISP server mode with HTTP capabilities in not yet available on Win32.
target context MAIN is now disabled in 'def-new' and 'new' because it would
cause ambigous situations when copying context vars after fixing a related
bug: def-new and new on context-vars
on UNIX a shared memory address obtained with 'share' can be unmapped using
(share nil <address>)
'put-url' with "Pragma: append\r\n" in header option appends when talking
to newLISP server
'read-file', 'write-file' and 'append-file' accept "http:// ..." and
for HTTP mode and "file://..." for normal file mode.
in HTTP mode they work exactly like 'get-url', 'put-url' and 'put-url'
with "Pragma: append" in the header option.
new QA file qa-net for testing newLISP server modes with:
net-eval, load, save, read-file, write-file, append-file
new QA file qa-utf8 to display UTF8 characters, this is not a test for
newLISP but rather the UTF8 display capabilities of the platform running on
8.9.9
matrix operations now can be performed on arrays (previously only lists)
matrix operations will return the type (list or arrray) which was given
as input. In case of mixed input (i.e. in multiply), array type is
returned.
new function 'det' returns the determinant of a square matrix expressed
as a list or array.
fixed cell leak in define-macro when exercising default values
64-bit integers where not displayed correctly in Win32 MinGW
8.9.10
'append', 'first', 'last', 'rest', 'slice' (and implicit slicing) now also
available for arrays
(timer 'event 0) did not stop on Win32
a fix in Curl_base64_decode() for bad base64 strings
20% speed up for append on strings and join
8.9.11
'append' did not append correctly to lambda lists, which lost lambda attribute
'qa-net' fixed (this file only tests on UNIX)
8.9.12
'int' did a signed instead of unsigned conversion
'save' did not save global protected symbols in a way they
could be reloaded
8.9.13
'local' like 'let' but no initialization of locals (all nil):
(local (x b x) body)
'swap' has a third syntax pattern to swap the contents of symbols: (swap x y)
8.9.14
speedup and memory savings on 'apply'
fixed INT64->string conversion in sym for True64/WINCC
error checking on all reallocs()
changed to realloc() in writeStream() routines
8.9.15
(join '(1 2 3)) was hanging, instead of wrong datatype error message
support "\x41\x42\xff" in string hex format equivalent to "\065\066\255"
new 'ref-all' returns a list of index vectors for all ref's of an expression
(ref-all 'a '(a b c (d a f (a h a)) (k a (m n a) (x))))
=> ((0) (3 1) (3 3 0) (3 3 2) (4 1) (4 2 2))
9.0.0 Release October 15th, 2006
9.0.1
'read-file' did not read extended http:// mode parameters correctly
new 'doargs' works like 'dolist' iterates through (args)
(define (foo) (doargs (i) (println i)))
(foo 1 2 3) => prints 1 2 3
implemented on top of 'dolist' also does $idx and break-expressions
'explode' takes extra parameter for # of characters (works on UTF-8 too):
(explode "newlisp" 2) => ("ne" "wl" "is" "p")
new 'utf8len' length of a string in UTF-8 characters
new scalar matrix operations (matrix is a 2 dimensional list or array):
(set 'A '((1 2 3) (4 5 6))
(set 'B A)
(mat + A B) => ((2 4 6) (8 10 12))
(mat - A B) => ((0 0 0) (0 0 0))
(mat * A B) => ((1 4 9) (16 25 36))
(mat / A B) => ((1 1 1) (1 1 1))
Note that all matrix operations are in floating point
9.0.2
explode works on lists:
(explode '(a b c d e)) => '((a) (b) (c) (d) (e))
(explode '(a b c d e) 2) => '((a b) (c d) (e))
many structural transformations can be done combining 'explode' and 'transpose'
fixed cell-leak in 'ref-all'
in (mat <op> A B) B can be a single number:
(mat + '((1 2 3) (4 5 6)) 2) => ((3 4 5) (6 7 8))
some fixes for HTTP mode on UNIX
HTTP mode now working on Win32 but with some timing issues,
see header of file qa-net for details
9.0.3
$idx was broken after 9.0 starting with 1 instead of 0
9.0.4
fixed midnight rollover in 'timer' on Win32
new (round <number> <precision>) rounds a number to precision digits
left (positive) or rigt (negative) of the decimal point
new hyperbolic functions sinh cosh tanh
fixed push -1 optimization when popping only remaining element in list
new 'ostype' symbol holds os type string
new 'delete-url', needs to be enabled on target www server (most aren't)
else => "ERR: server code 405: HTTP/1.1 405 Method Not Allowed\r\n"
and must have file permissions set accordingly on target file;
additional parameters like timeout and custom headers are available
exactly as in 'get-url', the feature is also available in:
(delete-file "http://......"), similar to HTTP mode in 'read-file',
'write-file' and 'append-file' and is also implemented in newlisp
server mode (not working on Win32 newlisp server mode)
GET queries are now supported in newlisp server mode (not yet Win32)
9.0.5
'and' and 'or' now () when failing and last evaluation was ()
GET and POST cgi now working on UNIX and Win32 (9.0.6)
new -w <working-directory> commandline switch
useful for changing working directory after newlisp startup:
newlisp -c -d 8080 -w /Users/lutz/ide
this is the same as going into the directory and starting newlisp
newlisp -c -d 8080
newlisp can now run as a webserver doing newlisp based CGI. It runs both
newlisp-ide-x.x.tgz and newlisp-wiki-x.x.tgz, to run the ide on the local
machine:
newlisp -c -d 8080 -w /usr/home/www/ide
then in a webbrowser enter the URL http://localhost:8080/
index.cgi and index.html are looked for by default if no filename is
specified in URL
httpd example programm has been eliminated, because httpd mode now built-in
into newLISP
'file-info' now correctly reports filesizes > 2G (2147483647) bytes
now also can index: (file-info <path-name> 0) => filesize
the -x commandlne switch has been disabled, use newlisp server modes instead
fixed problems with break-condition in dolist/doargs introduced in 9.0.1
fixed problem when break-condition is the loop symbol itself
9.0.6
'nth' now with similar syntax options as 'net-set/set-nth'
new in 'nth':
(nth (L <idx1> <idx2> ...))
(nth (L <aref>)) ; where <aref> is a list of indices
new in 'set=nth', 'nth-set'
(set-nth (L <aref>) <newval>)
(nth-set (L <aref>) <newval>)
'file-info' now distinguishes in the mode field (12th bit) between links
and normal files:
(define (link? fname) (= 0x2000 (& (file-info fname 1) 0x2000)))
not on Win32, who knows the correct Win32 function for lstat() on MinGW gcc?A
9.0.7
HTTP server mode looks for procedure httpd-conf for processing/transforming
the path-file-name of the request. This way security checks, remappings etc
can be performed. In this case a file httpd.conf containing the definition
of httpd-conf can be loaded when starting the server:
newlisp httpd.conf -c -d 8080 -w www/httpddocs
if the file httpd.conf contains:
(define (httpd-conf request)
(if (ends-with request ".exe") "errorpage.html" request))
now any request for a file which finishes in .exe will be transformed into a
request for errorpage.html containing an error message for the client.
fixed HTTP server mode crash on LINUX
fixed 'nth' which failed on old mode when indices where expressions
9.0.8
new syntax of 'nth' should work on protected symbols
new syntax of 'set-nth/nth-set' did not check for index maximum of 16
make httpd-conf safe for non-string returns
server mode now correctly remaps directory paths when performing CGI
in directories not web root, i.e. http://ahost.com:/ide/ will work with CGI,
note that directories need to end with "/" to make the resolve to index.html
or iondex.cgi work correctly
new -http flag like -c (suppressing prompts) but only allow HTTP commands
no newLISP statements (-c allows both), this is a 'safe' HTTP mode not
allowing 'net-eva' or other commandline protocols.
The following configurations can be used:
(1) serve HTTP requests only
newlisp -http -d <portno> -w <www-root>
newlisp -http -w <www-root> # started vi INIX inetd or xinetd
(2) serve 'net-eval', HTTP and command line without prompt
newlisp -c -d <portno> -w <www-root>
newlisp -c -w <www-root> # started via UNIX inetd or xinetd
this mode is useful when running newLISP server in a controlled environment
behind a secured firewall in a distributed computing environment where
newLISP server must answer to both: net-eval and HTTP requests.
Note that on Win32 a \tmp directory must be created on the same drive
which is current for CGI processes for newLISP HTTP mode to work correctly
for CGI processing. On UNIX /tmp is standard.
fixed 'invert' crash (since v.9.0.2) on not-invertible matrices
upgraded to better random number generation in 'rand' and 'random'
(not available on Win32)
fixed (rotate '(1) -1)
9.0.9
another fix for 'nth' and protected symbols
if 'httpd-conf' returns 'nil' nothing will be processed, this can be
used to completely hand off CGI request processing to httpd-conf
9.0.10
moved env variable creation of DOCOUMENT_ROOT earlier, so it is available
in httpd-conf.lsp
added httpd-conf.lspi to the examples directory in the source distribution,
now filters csertain file extensions and does not allow access to files
outside the web directory tree specified with the -w option:
newlisp httpd-conf.lsp -http -d 8080 -w /wwwdocs
or outside the startup directory if no -w is given, also takes care
of request for directories when no trailing '/' is present
cleaned up nthArray and implicitIndexList/array code
trying to 'set-nth' and empty list should return the empty list not nil
more tests in qa-dot and qa-comma for symbol protection and 'nth'
9.0.11
rework of whole indexing area, now correctly honors symbol protection in
all modes if symbol is nested inside an expression. The old flat mode:
(nth i j alist)
is much slower, instead use one of the following modes:
(nth (alist i j)) or (alist i j) or (nth (alist aref)) or (alist aref)
ehere aref is a list of nymbers, i.e.: (1 2), same modes in set-nth,nth-set
reworked nil and empty list detection throughout all files. 'nil' and the
empty list '() are logic false, things work like this:
(map true? '(nil () 0 "")) => (nil nil true true)
(map nil? '(nil () 0 "")) => (true nil nil nil)
(map not '(nil () 0 "")) => (true true nil nil)
(map null? '(nil () 0 "")) => (true true true true)
in v9.0.0:
(true? '()) => true, which was wrong because also
(true? (not '()) => true, which is correct
this affects filter and index usage with true? as predicate, but does not
affect: if, unless, while, until, do-while, do-until, which always worked
correctly assuming '() as logical false
'name' also can take contexts i.e.:
(set 'L:L '(a b cd)) (set 'x L) (name x) => "L"
now when evaluating a context by itself it returns the default symbol
if the default symbol does not exists it gets created:
(set 'foo:foo '(a b c d e f g))
(foo) => foo:foo
(eval (foo)) => '(a b c d e f g)
this can be used for reference passing:
(define (mysort ctx func)
(sort (eval (ctx)) func))
(mysort foo >) => (g f e d c b a)
foo:foo => (g f e d c b a)
previously a passed context could only be used for functions using
index lists and implicit indexing as in (nth-set (ctx idx) value) etc.
now functions working on the entire list can be used with reference passed
data. THIS FUNCTIONALITY HAS BEEN DISABLED IN 9.0.14, as a workaround
use (sym (name ctx) ctx) to retrieve the functor
9.0.12
the newLISP-tk installer now contains a file md5-checksums.txt with
checksums for newlisp-tk.exe, newlisp.exe and newlisp.dll
bit not ~ was still on 32 bits now 64 like all integer arithmetik since 9.0
all buffer variables moved to size_t and ssize_t type in preparation for
64-bit model LP64 compile for 64-bit memory addressing.
get-char, get-int, get-float and get-string failed when using on 64-bit
addresses, which where not truncated correctly on little-endian CPUs.
This affected the mysql.lsp and mysql5.lsp modules when using with newLISP
versions 8.9.7 and later and on Intel CPUs. On Mac PPC and other big-endian
architectures this problem did not occur. All other modules where not affected
on any architecture.
<,>,<=,>=,= when given only one argument compare agains 0, "" or (),
all other data types return true as before
(< 1) =>nil, (= 0) =>true, (> "abc") => true, (= "") =>true etc.
64-bit file poisitioning fixed under Win32 (now runs qa-lfs)
9.0.13
fixed problems in the new <,>,<=,>=,= single argument feature
9.0.14
further fix in 64-bit ~ function
a context feature intoduced in 9.0.11 to extract the default functor from an
unknown context has been disabled, instead use the workaround:
(set 'foo:foo '(a b c d e f g))
(set 'ctx foo)
(sym (name ctx) ctx) => foo:foo
(sort (eval (sym (name ctx) ctx)) >) => (g f e d c b a)
foo:foo => (g f e d c b a)
a more elegant way will be supplied in the future
both string and list versions of 'explode' now return an empty list if optional
length <= 0
'nt-set/set-nth' did not honor constant protection of default functors
now compiles for LP64 64-bit memory model on 64-bit LINUX using the makefile:
make -f makefile_linux64LP64
or simply:
make linux64LP64
the old makefile for making a ILP32 32-bit newlisp on 64-bit LINUX has been
renamed:
make -f makefile_linux64ILP32
or simply:
make linux64ILP32
tested on a AMD64 CPU with LINUX 2.6 64-bit Fedora 3
enjoy up to 17,179,869,184 gigabytes or 16 exabytes of RAM, on AMD64
the LP64 compiled version is 12 to 25% faster than the ILP32 version
avoid sign extension when unpacking signed 32bit into unsigned 32bit displayed
in 64-bit: (unpack "lu" (pack "ld" -1)) => (4294967295) ; not (-1)
added 'get-long' and "Ld", "Lu" 64-bit packing formats
new 'parse-date' for parsing date strings (not yet working for Win32)
9.0.15
more manual additions and changes, moved all predicates into own group
fixed dynamic symbols compare
fixed warnings fo missing -Wno-strict-alasing GCC message on older Solaris
and BSD GCC versions
fixed parsing of [text] tag on 64-bit compiles
fixed 'flt' for TRU64 compile
tried Linux debian package, Ok on Ubuntu, will be included from now on
in newlisp.org releases, but appreciate help in getting it into Ubunto
and Debian for inclusion into their lists
The Tru64UNIX compile using makefile_tru64 is now a large pointer model LP64
compile, thanks to Peter for porting and testing on an Alpha CPU
added makefile_darwin_LP64 for 64-bit compile/link, but cannot test it
on my PPC-G4 (I believe I need a G5 for this)
fixed 'char' on UTF-8, bug due to 64-bit changes
LP64 mode for Solaris workng, use makefile_solarisLP64
new 'make test' to run qa-dot, qa-net, qa-xml
9.0.16
OS/2 compile flavor now part of distribution
fix for Solaris in some networking routines broken in 9.0.2 !
fixed: (dup x -1), which was broken since 9.0.14
'make test' now does qa-dot, qa-xml, qa-setsig, qa-net all one after
another. The qa-setsig script will drop out on Win32 with a message.
A small change in the 'test-process' routine in the qa-dot script will
cause less failure message for 'process' on slow computers.
qa-dot now will set to locale "en_US' when testing an UTF-8 version,
this has been done to suppress failure messages for UTF-8 'upper-case'
and 'lower-case' which do not work in the default 'C' locale in
UTF-8 mode on some platforms.
qa-comma always sets to "de_DE"
'asinh', 'acosh', 'atanh' complete the triginometric functions
up to 8 'callback' routines cain be defined to be called by an imported
library, example for Glut lib:
(glutDisplayFunc (callback 0 'draw))
(glutKeyboardFunc (callback 1 'keyboard))
(glutMouseFunc (callback 2 'mouse))
up to four parameters (32-bit ints) are received by the user-defined
callback handlers. See the file newlisp-9.0.16/examples/opengl-demo.lsp
for details. Note that OpenGL passes floating point data, which are only
handled correctly on x86 based platforms. On the Mac PPC this file will
not work (although the callback interface itself does work, but no
drawing will be visible).
9.0.17
fixed 'non-blocking' bug for write on Linux, thanks Peter!
number of maximum cells was not reported correctly in 64-bit newLISP
'ref' and 'ref-all' now can take a comparison functor (like 'sort') for
comparison: (ref-all key List func), if no func is specified
assumes = (equal), ref-all now much faster on big lists with many finds.
'find' and 'replace' (both in their list forms) can take a comparison
functor like 'sort', 'ref', 'ref-all'.
'replace' for lists now also processes $0 (old entry) in replacement
expression.
using replace for lists with 'match' or 'unify' as comparison functor
makes 'replace' as powerful as 'replace for strings with regular expressions.
This is an important new feature with many applications. It also gives
the much overlooked 'match' and 'unify' the more frequent usage they deserve.
new logic functions 'exists' and 'for-all' apply a condition to each
element in a list and return the result.
match now will accept atoms in the entry expressions to make it usable
for 'ref' and 'ref-all'
9.0.18
fixed a bug in (pop <string> <idx>)
9.0.19
(find <str> <str> [<option>]) will do both: regex if option is a number
(as before) and function comparison if option is a funtor or user-defined
function.
fixed 'pop' on an empty string
fixed newlisp -h where new options didm't show
'file-info' was hanging on name pipes now shows 0 for file size
trying to start server mode with no or zero port will fail
'array' will give error message on negative parameters, before
they where simply skippped
Ctrl-C signal handler crashed on Linux when in -d mode
'explode' will take optionl 'true' to omit chunksize too short when
chunk size is given (strings and lists)
(explode "newlisp" 3) => ("new" "lis" "p")
(explode "newlisp" 3 true) => ("new" "lis")
9.0.20
-l and -L mode now always must specify a path-name for the
log file (either attached or detached):
newlisp -l /usr/home/www/logfile.txt
logging is allowed in all modes. -l will only log network connections
or commandline or net-eval requests input. -L will log also HTTP requests
and newLISP output from commandline and net-eval
doc installation directory changes from /usr/share/newlisp/doc to
/usr/share/doc/newlisp
CodePatterns.html ammended with chapter for HTTP only server mode
MemoryManagement.html ammended with implementation chapter
newLISPdoc.html and inewLISP-X.x-Release.html added to install
in /usr/share/doc/newlisp, this file will only change on mayor
releases
9.0.21
a crash bug in 'match' introduced in 9.0.17 was fixed
new 'curry' (curry f x) => (lambda (y) (f x y)), makes a unary opearator
out of a binary operator, useful when using 'match' 'unify' and other
binary ops in: 'filter', 'clean', 'index' etc., i.e:
(filter (curry match '(a *)) '((a 10) (b 5) (a 3) (c 8) (a 9)))
=> ((a 10) (a 3) (a 9))
9.0.22
integrated syntax highlighting into newlispdoc, which now is part of
installation in /usr/bin/ and with man page in /usr/share/man/man1
added media types for .pdf .mov. .mpg and .mp3 in HTTP request handling
additionally to .jpg .png .gif
protect stack from overflow when loading huge contexts in sysEvalString()

safer memory allocation for net-ping when using wildcard *
new module crypto.lsp with md5 and sha1 hash functions
fixed bug in Win32 version when stdout of more than 2048 chars
in shell window
9.1.2
net-peer, net-local and net-receive-from where dropping the third digit of the
least siginificant IP group in the IP-string return value on 12 digit IP numbers
9.1.3
makefile_osxLP64 produces a 64-Bit version on intel core 2 duo which passes
'make test'. Use: make osxLP64 or: make -f makefile_osxLP64
some cleanup in nl-sock.c
newlisp-tk.tcl now detects default browser in Debian LINUX
9.1.4
passed all rand() to newer, better random() in nl-math.c
local domain UNIX sockets using: (NOTE THAT SYNTAX CHANGES IN 9.1.5)
(net-listen <str-path> "local") and (net-connect <str-path> "local")
then use 'net-accept', 'net-select, 'net-send' and 'net-receive' as usual
see also file qa-local-domain
fixed many problems with 'net-ping' which did not work correctly on
machines rejecting out of sequence errors in ICMP packets. Now will handle
EHOSTDOWN and EHOSTUNREACH errors correctly
'net-ping' now also can accept ranges, e.g: (net-ping 192.168.1.120-150)
additionally to the '*' star, i.e: (net-ping 102.168.1.*)
superuser permission are required for net-ping
added MySQL:escape to mysql.lsp (v.4) and mysql5.lsp, thanks to Jeff
for submitting this addition
added HTTP_COOKIE to environemnt variables set by newLISP HTTP server
mode
leading and trailing white space now gets removed from environment variables
set by newLISP server mode, specifically in HTTP_HOST, HTTP_USER_AGENT and
HTTP_COOKIE
9.1.5
changed the way of specifying local-domain UNIX sockets in net-connect and net-listen:
(net-connect <local-socket-path>) ; don't specify a port
(net-listen <local-socket-path>) ; specify socket-name instead of port)
local domain UNIX socket support in newlisp -d server mode and net-eval:
server mode: newlisp -d /tmp/mysocket
client: (net-eval "/tmp/mysocket" 0 "(+ 3 4)") => 7
speedup utf8_wlen()
load and save do not use lisp source anymore but call getPutPostDeleteUrl() directly
this increases speed and leaves get-url/put-url to be renamed if required
guard against partial send()'s in net-eval and HTTP mode on Win32
'net-eval', 'net-ping', 'net-receive-from' and 'net-receive-udp' now set
timeout error for retrieval with 'net-error'
'net-ping' will stop waiting for response when the number of responses
reaches the number of pings even if no max count was not specified.
a fix for local-domain UNIX sockets on OS/2
reorderd "3. Functions in groups" subchapters adding group "Pattern recognition"
now any keystroke/mouse-button will close the about windows in newLISP-tk.
Before only <esc> worked
9.1.6
newlisp-x.x.x/util/nclocal.c utility program similar to nc/netcat but for
local domain UNIX sockets.
When deleting contexts the context symbol now will stay and not be deleted
but demoted to a normal unprotected symbol.
It is now possible to create contexts on local variables in 'define',
'lambda' or 'local' expressions without error messages on usage of these
symbols/variables subsequently. After leaving the 'define', 'lambda' or
'local' the variable symbols will be returned to their previous status in
the upper scope. Before this version they staid protected.
Note: For efficiency reasons this coding practice is not recommended but
will not cause an error anymore.
use strncmp() instead of strcmp() in netReieive() to avoid buffer overflows
read empty [text][/text] tagged text correctly
newlisp doc v.1.1 fixes formatting of the syntax line when parenthesized
expressions are part of the syntax line.
9.1.7
a fix for ends-with when using with regular expression option (did not anchor
correctly to the end)
net-listen didn't evaluate the port parameter since 9.1.4 when local domain
sockets where introduced
9.1.8
fixed a crash bug on Win32 when using a permission mask in make-dir
'%%' as a last spec in format was not translated correctly
9.1.9
when a system wide error handler defined with error-event contained 'nil
newLISP would go into a loop caused by an error invoked by the error handler
now an error-event defined with a symbol containing nil will simply to
nothing.
xml-parse now can take an optional callback functor (see manual for detail)
on the Win32 UTF-8 versions UTF-16 file-path names now are processed
correctly, thanks to Michael Sabin for contributing the file win32-path.c
this is the first release containing the source of Java based GUI-server
in the guiserver subdirectory of the distribution. guiserver.jar is
already prebuilt contained in the source distributin and installed
drng the normal newlisp install. It also can be installed individually
descending into newlisp-x.x.x/guiserver (read README.txt found there)
new global? property function checks if a symbol is global
new protected? property function checks if a symbol s protected
a bug in push on strings when the index was > the length of the string
and a fix for utf8
9.1.10
this development release was made for additions in newLISP-GS
9.1.11
fixed a bug in explode when specifying N > length of string
negative second length in slicing now interpreted as offset
from the right: (2 3 "abcdefg") => "cde", (2 -3 "abcdefg") => "cd"
before negative length would be interpreted as going to the end
implicit n-resting on strings was UTF-8 sensitive which it should
not be, all implicit indexing and slice on strings is on byte borders,
only first,last,rest are UTF-8 sensitive.
fixed crash when net-select was interrrupted by timer, traceExit()
was not protected from entry when signal handlers where defined
9.1.12
newlisp invoked on the command line can take URLs for filespecs to execute
remote programs: newlisp http://newlisp.org/example.lsp
join now can take an extra flag to force a joint string after the last element:
(join '("A" "B" "C") "-" true) => "A-B-C-"
9.2.0 Release August 15th, 2007
9.2.1
rewritten 'count is about 3-4 times faster than before when counting 100
in 1,000,000 elements. Only on Mac OS X and other UNIX. On the older
MinGW GCC C library the required functions tsearch() and tfind() are not
available.
fix for special characters in cookies cookies in cgi.lsp
'pack' now can take lists for data:
(set 'lst '("A" "B" "C"))
(set 'adr (pack "lululu" lst))
(map get-string (unpack "lululu" adr)) => ("A" "B" "C")
This was imnplemented in response to a request for a (address <list-of-strings>).
Note that the lst should not be changed and be referenced directly in 'pack'
so the pointers passed by 'adr' are valid. 'adr' would be a 'char * adr[]' in the
C-programming language
fixed cell leak in indexed sys-info and indexed file-info
new 'dostring' iterates over a string with character values in loop variable.
On UTF-8 compiled newLISP UTF8 character values are returned by the loop variable
documented 'bind' :
(bind '((a 1) (b 2) (c 3))) same as (map set '(a b c) '(1 2 3))
This function was already in earlier versions, but not documented.
on startup NEWLISPDIR will be registered as either: /usr/share/newlisp
on Mac OS X / UNIX as: PROGRAMFILES/newlisp on Win32, where ROGRAMFILES
is an exisiting Windows environmnt variable. (env "NEWLISPDIR") =>
additions in guisserver.lsp and newlisp-edit.lsp, see guiserver/CHANGES
9.2.2
iterators segfaulted when evaluating the iterator variable was the last
statement in the iterator body: dostring, dolist, dotree.
Added test-cases for this situation.
(main-args) could be pop'ed which was due to an implementaion error, main-args
cannot be popped any more, if necessary, assign to another variable first:
(set 'margs (main-args)), (pop margs) etc.
additions in guisserver.lsp and newlisp-edit.lsp, see guiserver/CHANGES
9.2.3
addtions, changes in guiserver.lsp and newlisp-edit.lsp, see guiserver/CHANGES
for details
misc. code cleanups in core
9.2.4
in 'set-nth/nth-set' when no replacement arg is given, the old value should
be returned only as in 'set'. Was replacing with nil.
fixed a cell-leak in 'set' when using mutliple arg pairs.
allow symbols for the name in (context <ctx> <name> [<value>]), previously
only strings where allowed.
speedup in symbol deletion
in (signal <sig-no> <handler | flag> the nil flag now specifies SIG_IGN
and the true flag SIG_DFL. Before 9.2.4 nil would specifiy an empty newLISP
handler and the true flag was not available.
reworked 'process' now creates the new process without the previous
time and memory overhaead (on UNIX) of an extra newlisp fork which stayed
in memory until the newly created process had finished.
In most cases the full path must be given for the command in 'process'.
new 'destroy' to destroy processes created with 'process' or 'fork'
see reworked docmentation for 'fork' and 'process'
fixed a bug when sorting (ordered compare) mixed boolean values/symbols
9.2.5
'dup' without the repetition number parameter will assume 2, i.e:
(dup 'x) == (dup 'x 2) => (x x) ; Thanks to Lance Bradley for this idea.
'find-all' will return an empty list '() when nothing is found, previously
nil was returned.
':' now also works like a function and can be attached to symbol following
it. The colon operator forms a context symbol from the symbol following it
and the context symbol found as the first element of the list contained
in the next argument.
(define (rectangle:area p)
(mul (p 3) (p 4)))
(define (circle:area c)
(mul (pow (c 3) 2) (acos 0) 2))
(set 'myrect '(rectangle 5 5 10 20)) ; x y width height
(set 'mycircle '(circle 1 2 10)) ; x y radius
(:area myrect) => 200 ; same as (rectangle:area myrect)
(:area mycircle) => 314.1592654 ; same as (circle:area mycircle)
This can be used for simple OO programming where objects are represented
as lists and methods are packaged contexts / namespaces serving as object
classes. The colon ':' operator implements polymorphism by looking up
the class / context of the object as the first symbol in the object list.
'integer' the long writing of 'int' will be eliminated in the next
development version!!!
new versions newlisp-ide-4.1.tgz and newisp-wiki-4.2.tgz have changed
'integer' to 'int'
better platform independent library detection routines in modules:
crypto.lsp, gmp.lsp, sqlite3.lsp and zlib.lsp
crypto.lsp has new 'crypto:hmac' as of RFC 2104 used for Amazon REST API
new util/newlisp.vim, for matching .vimrc see http://newlisp.org/code/vimrc.txt
9.2.6
Moved to MinGW 5.1.3 with gcc v.3.4.5 and eliminated declarations for
struct timezone and gettimeofday(). Changed sleep() to Sleep().
-> grep 3\.4\.5 *.c <- shows all changes
Improved random number generation with 'rand' now gives better integer quality
random numbers on Win32, which only does 16 bits in 'C' random(), even for
ranges close to or > 16bit.
newLISP GS 1.07 now automatically restarts monitor shell, if required by run-command.
newLISP GS 1.07 now loads, saves and displays UTF-8 correctly in editor and
interactive monitor area
new manual chapter: "Object Oriented Programming in newLISP" explaining
newLISP object format and how to use the new : (colon) operator.
9.2.7
changes in newLISP-GS to automatically detect and switch to UTF-8 mode, depending
on the newLISP executable. Edited chapter "17. Object-Oriented Programming in newLISP"
(thanks Michael Michaels)
In Guiserver 1.08:
new gs:window-moved and gs:window-resized. See new demo file move-resize-demo.lsp
9.2.8
get-url, post-url, put-url and delete-url have been extended and reworked:
- now return extended error information if supplied by the server, before only
the error cocd was reported.
- now can take a trailing "debug" in the option string, i.e."list debug" or
"header debug" or simply "debug" when neither "list" or "header" applies. The
debug option will print all outgoing info onto the console screen.
in some situations an empty document returned was reported as "ERR: empty document"
when ist was not an error but intended by the server.
in some situations customheaders were only taken when the option string was
present too. The manual showed the option-string optional, which it is.
the server response code 204 is now handled correctly
when using a custom header "Content-type:" must be defined for put-url, before
"Content-type: text/html\r\n" was assumed.
9.2.9
last element speed optimization for 'last', 'nth', 'nth-set', 'set-nth' and
implicit indexing with index -1.
'sort' can now be used on arrays too
changes in newLISP-GS for editor keyboard short cuts and list-boxes, see
guiserver/CHANGES file
the newlispdoc utility has improved pager headers and a feature to point to
other module collections from the index page.
9.2.10
new functions to modify nested lists by reference via a key:
(set-ref (L key) value)
(ref-set (L key) value)
(set-ref-all (L key) value)
basically 'set-ref' and 'ref-aset' are shortcuts for doing a ref and
using set-nth/nth-set on the result:
(set-ref (L key) value)) equivalent to (set-nth (L (ref key L)) value)
(ref-set (L key) value)) equivalent to (nth-set (L (ref key L)) value)
all ref functions support either:
(<func> (L key) [...]) or (<func> key L [...])
syntax similar to nth functions working with indices instead of keys
like with 'set-nth' and 'nth-set' L can be the context of the default
functor L:L containing the list for passing lists by reference
all 8 'nth' and 'ref' functions together now constitute a complete set of
functions for indexing, referencing, accessing, modifying and search and
replace on nested lists. All 8 functions are also capable of receiving
lists passed by reference via context default functors, passed only by
their context name. All functions now offer the same two syntax patterns
with either one index and the key followed by the list:
(<function> <idx>|<key> <list> ...)
or the parethesized formi, which also can take contexts as default functors:
(<function> (<list> <idx>|<key>) ...)
on Win32 function 'directory?' now will accept training slahes '\' or '/'
before it would always fails on trailing slashes
9.2.11
'ends-with' with regex options failed when alternative pattersn where used
and the succeeding pattern was last
fixed directory? for drives on Win32
define MY_RAND_MAX as 0x7FFFFFFF for TRU64 flavor
added mysql51.lsp module for MySQL v.5.1
9.2.12
indices overshooting the list at the end (too big positive index) and
indices overshooting the list at the beginning (too big negative index)
now cause a "list index out of bounds" error. Before the last or
first element of a list was returned instead.
This affects the functions: nth, set-nth, nth-set, push and pop
If more indices are present than nesting levels, these are discarded as before.
Popping an empty list will return nil.
Fixed a stack overflow in the new 'set-ref-all'
Changes in the newlisp-edit.lsp GS editor, see guiserver/CHANGES
The environment variable NEWLISPDIR will only be created and set if it does
not exist. An exisiting definition of NEWLISPDIR will not be overwritten.
9.2.13
a bug fix in set-nth, nth-set, ser-ref, ref-set (in getList() ) when first
element in an implicit index parameter list evaluates to a context
9.2.15
assoc, set-assoc (old replace-assoc) and new assoc-set all take mutiple keys
for multilevel association lists
fixed stack overflow in ref, set-ref, ref-set
9.2.16
set-assoc and assoc-set redone, fixes for set-ref, ref-set, set-ref-all
newlisop_manual.html updates
9.2.17
Fixes for 'set-assoc' and 'set-ref' when using the wrong syntax
new 'pop-assoc' for removing associations
'find' and 'ref' put their last found expression into $0 when used with a
cpmparison functor as parameter
'find-all' has two additional syntax patterns
'process' now parses commands and args delimited by single or double quotes.
This is necessary when using file name or argumemnts containing spaces.
On Win32 do: (process {newlisp '"test prog.lsp"'})
On Unix do: (process {newlisp 'test prog.lsp'}) ; single or double quotes work
The octal format spcecifier (format "%o" 8) => "10" will work on many
platforms compilers. This is now documented and useful when inspecting
the mode number from the 'file-info' function.
9.3.0 prerelease January 28th, 2008
fix in 'sys-info' for some 64-bit compilations, and other int -> size_t
reset -w base directory after http requests, this is important in -c mode
when both, http and net-eval requests may come in, so that http requests
cannot change the current directory of the server for net-eval requests
9.3.0 final release February 1st, 2008
a fix for newlisp server mode when using IE explorer on Win32
documentation changes
9.3.1
doc changes
fixes for guiserver v.115 (see guiserver/CHANGES)
fixed error message for unclosed curl brace
'pop-assoc' should not set $0 as do 'set-assoc', 'assoc-set'
: colon operator should not evaluate args after the object
new 'read' exposes the internal source code reader. 'read' can be used to
write preprocessor for newLISP source or specialized newLISP editors and
evaluators. When using 'read' in string mode, comments are preserved.
'read' takes as argument a source string, a callback function and an optional
context. The callback function is called with each expression as either a string
including comments or an expression if the context argument is present.
When a context argument is present the source gets compiled in the namespace
specified by the context, except when overwritten by context statements in
the source. The string mode (no context is specified) still will check
the source if it is well formed, with balanced parenthesis and quotes and
interrupt processing with an error messages, if finding mal-formed s-expressions.
'read' returns the last return value of the callback function.
syntax: (read <str-source> <functor-callback> [<context>])
example:
(define (crunch sx) (println "=>" sx))
(set 'code "; a statement\n(+ 3 4)\n(define (double x) (+ x x))")
> (read code crunch)
=>; a statement
(+ 3 4)
=>
(define (double x) (+ x x))
"\n(define (double x) (+ x x))"
>
Note, that string mode conserves orignal formatting in the expression and
leading comments returned.
Following a context is specified forcing 'read' to return compiled expressions:
> (read code crunch MAIN)
=>(+ 3 4)
=>(define (double x)
(+ x x))
(define (double x)
(+ x x))
>
'read' is renamed to 'read-expr' in 9.3.4
9.3.2
new compile flavor for IPv6 with the following makefiles:
makefile_darwin_utf8_IPv6
makefile_linux_IPv6
makefile_bsd_IPv6
elimnate quirky symbol syntax in 'net-send'
functions called by dynamic symbols now switch to the dynamic
context:
(define (foo:foo) (context))
(set 'ctx foo)
(ctx) => foo
(ctx:foo) => foo ; previously MAIN
changed report format in 'net-ping' now includes roundtrip time in
micro-seconds
9.3.3
fixed display of signon banner, which made newlisp-tk.tcl not work. Also, in order
to make newlisp-tk.tcl work on 9.3.0 and after, the line in newlisp-tk.tcl:
(net-send SYS:tk-sock 'result)
should be changed
(net-send SYS:tk-sock result)
in the runtk.lsp utility (see http://www.newlisp.org/index.cgi?page=Tk_and_newLISP)
the line:
(process "wish" tcin tcout)
changed to:
(process "/usr/bin/wish" tcin tcout)
to make it work on v9.3.0 and after
'search' has a new flag parameter to put the filepointer after the search to either
the beginnig (nil) or the end (true) of the searched string.
added <hr> as a legal tag in v.1.5 newlispdoc formatted documentation
'xml-parse' crashed when not passing a valid symbol or context
extra boolean flag in 'bind' forces evaluation of bound parameters:
(bind assocList true) same as: (apply set (flat assocList))
this enables an efficient way to define functions with names parameters:
(define-macro (foo)
(local (len width height)
(bind (args) true)
(println "len: " len " width:" width " height:" height)
))
(foo (width 20) (height (+ 5 25)) (len 10))
outputs -> len: 10 width:20 height:30
a fix for 'expand' when expanding upper-case characters, now limited to 65->90
to prevent expansion of symbols starting with special characters
took out the 'read' from 9.3.1. Just couldn't see the benefit of it. Everything
which can be done with it can be done by redefining 'define', or create other
special def- functions which transform top-level expressions.
'env' now removes an enviroment variable when setting it to an empty string
except when on Solaris, where it stays as an empty string.
(env "VAR" "value") (env "VAR") => "value" (env "VAR" "") (env "VAR") => nil
On Solaris (env "VAR") = "".
For a platform independent check use (null? (env "VAR"))
fixed a memory leak on Win32 and Solaris when repeatedly setting the same
environment variable
9.3.2 did not compile on Solaris, 9.3.3 now does
9.3.4
creating dictionaries (hashes in other languages) got faster and shorter:
the default symbol if it contains nil works like a hash function creating
and setting the symbol made from the string following it:
(define Foo:Foo) ; create namespace and default functor
(Foo "bar" 123)
(Foo "bar") => 123
'read' which was introduced in 9.3.1 but taken out in 9.3.3, has been put
back as 'read-expr' and documented. The critical advantage over using
eval-string on quoted strings is, theat read-epr is reading only one expr
at a time and its ability to return comments when returning strings
a fix when serializing illegal symbols with (save (sym <str> <context>) ...)
forcing the <context> to be written with MAIN prefix, also: overwrites of
'set' and 'sym' will not be saved, as they make it impossible to load
serialized contexts.
newlispddoc now does create HTML files without CSS style definitions but HTML
files try to to read newlispdoc.css from the same directory and load it, if
they find one. A sample newlispdoc.css with the usual style definitions can
be found in newlisp-9.3.4/util/newlispdoc.css
(sys-info -3) is now the current process id (pid). This pid can be usedd to
'destroy' (kill) the process on MAc OS X and other UNIX. On Windows the pid
returned seems to have a different meaning and does not respond to destroy.
The Win32 SDK function GetCurrentProcessId() is used by newLISP internally to
get the pid.
9.3.5
Internally when using contexts as hashes, now an unserscore "_" is
automaically prepended. This eliminates the danger of overwriting
the default symbol or overwwriting 'set' or 'sym' in the namespace.
This way hash namespaces can be saves and loaded without taking precautions.
This is transparent to the user and the inetface has not changed:
(define Foo:Foo) ; create namespace and default functor
(Foo "bar" 123)
(Foo "bar") => 123
an association list can be passed to create a series of association hashes:
(Foo '(("var" 123) ("bar" 456) ("baz" 789))) ; create hashes from a batch
(Foo "var") => 123 ; (foo "bar") => 456 ; (foo "baz") => 789
without any parameter the context is converted to an association list
(Foo) => (("bar" 456) ("baz" 789) ("var" 123))
internally symbols are created with a prepended underscore
(symbols Foo)
(Foo:Foo Foo:_bar Foo:_baz Foo:_var)
'start-with', 'ends-with' and 'sym' now accept a quoted 'nil like other functions
taking flags
New 'regex-comp' allows to precompile patterns for all functions which take
regular expression patterns. newLISP already caches the last compiled pattern,
but 'regex-comp' is useful in case where repeated patterns alternate and the
single cache never gets reused.
(regex-comp <str-pattern> [<int-options>]) => compiled pattern
When using a regular expression function the compiled pattern gets passed
with the special option 0x10000, all other options are already contained in
the compiled pattern.
(set 'cp (regex-comp pattern))
(replace cp thetext replacement 0x10000)
Note that the option 0x8000 for replace once, cannot be compiled into the
pattern, but can be given together with 0x10000 as: 0x18000
fixed a bug for invalid (<list> <key>) syntax
9.3.6
smtp.lsp now can take user-name and password parameters for authorization
The behavior of 'wait-pid' has changed for finer control of child processes:
If nil is specified instead of the options number in 'wait-pid' then 'wait-pid'
will not block (WNOHANG option) and return 0 in the pid field of the return list,
if no childs exited, or -1 if no child processes are present, else the pid
ands status value of the signalling child are returned in a list. Previous
versions returned only the status value;
Using 'wait-pid' now causes the the SIGCHLD handler be set to the
default signal handler (SIG_DFL) of the OS as if (signal 20 true) has been
executed. This way 'wait-pid' can return pid values when handling child signals
On startup of newLISP the SIGCHLD handler is set to waitpipd(-1, 0, WNOHANG)
to avoid zombie processes when 'wait-pid' is not used for processes created
with fork or process.
added error message to 'error-event', 'signal' and 'timer' when handler parameter
supplied is not a symbol, lambda function or primitive
fixed an error in new namespace hash functionality when evaulating the value
expression
'lookup' can take an optional default expression, which is returned when the
association is not found: (looup <key> <assoc-list> [<index>] [<default>])
Various smaller speed ond code size optimizations introducing makeCell() helper
function and inlining getCell() into various functions
9.3.7
Cilk interface: 'spawn', 'sync' and 'abort'. See qa-cilk for workings.
Only available on Mac OS X and other UNIX like operating systems.
This API makes it easy to spawn child processes and collect results.
The API can be used recursively and automizes housekeeping and zombie
collection of finished processes.
'spawn' forks a process and passes a symbol for the result.
A 'sync' function waits for a max timeout on all processes and assigns the
results to the symbols spawned by 'spawn'. 'abort' can abort a specific or
processes. 'spawn' can be used recursively, so spawned child processes can
in turn spawn other children. newLISP uses shared memory to pass data up
to 4096 bytes or whatever the pageszie on the platform running. For data sizes
bigger than the pagesize newLISP automatically switches to a file based
data transfer using temporary files in /tmp/, where newLISP needs full
permissions to create, read, write and delete files.
SYNTAX:
(spawn <quoted-symbol> <function>) ; spawns the child process
returns the pid of the forked process
(sync <int-timeout>) ; waits for result up to milliseconds specified
returns 'nil' on timeout, or 'true' if all childs have finished. If
there are still pending childs 'sync' with a timeout parameter can
be called again.
(sync) ; only returns a list of pending child processes or an empty
list if nothing is pending. Does not do any other child processing.
(abort <int-pid>) ; aborts a specific child process and returns 'true'
(abort) ; aborts all child processes and returns 'true'
EXAMPLE:
(spawn 'x (foo-x a b c)) ; start first child
(spawn 'y (foo-y d e f)) ; start second child
(sync 10000) ; wait a maximum of 10 seconds and collect results
(println "x=" x " y=" y) ; print results
for more examples and a recursive application woth fibonacci see the
file newlisp-9.3.7/qa-cilk
For the original Cilk project (C-library API) see here:
http://supertech.csail.mit.edu/cilk/
9.3.8
Cilk API in WIN32 now simulates behaviour in UNIX. 'spawn' works
like 'set', 'sync' always returns an empty list and 'abort' always
returns 'true'. This way Cilk API code written for UNIX will also
run in WIN32, albeit slower.
bugfixes and improvments in Guiserver for newlis-edit.lsp, see changes
file for newLISP-GS.
added implicit indexing specific error messages.
'file-info' can be indexed (was not in docs)
second syntax in 'destroy' lets send any signal to UNIX process
(was not in docs)
9.3.9
'spawn' allowed usage of protected symbols
errors in child processes launched by 'spawn' are now automatically
catched and returned as a result string, before control was lost
and child processes could not be 'sync'ed
some refactoring/streamlining in error handling code
9.3.10
now the default functor as a container for lists or strings can be
used for any built-in function asking for a string or list. Until
now only functons of the special form (... (L idx) ...) could use:
(nth-set (L idx) value) when L:L => '(a b c d)
now any function can take lists or strings packaged this way:
(pop L) => a
or with strings:
(set 'S:S "abcdefg") (upper-case S) => "ABCDEFG"
This means that any user defined function when given a list or string
packed with a default functor will pass this list or string by reference
to any built-in function.
(char "") will return nil, caused out of range error message before,
'nil' more practical because one can switch on it: (if (char str) ...)
char, get-char, get-int, get-float, get-string now give an error for
missing parameter
server mode with -c or -http now disables commandline shell feature
with ! at the beginning of the commandline
9.3.11
(last S), (first S) and (rest S) did not work when S is a default
functor S:S with a list or string.
Fixed push when pushing at -1 on a sublist with one element
Fixed error messages text in list indexing area
Added out of bound error messages for 'swap'
Sortorder in manual should be as in (symbols) except for number ops.
Fixed many small HTML formatting inconsistencies in the manual. This
facilitates parseing out syntax lines for autimatic help functions.
'net-eval' now returns the error string if the remote server task ended
with error. Before the server would first time out then return 'nil'.
The new behaviour gives the choice of handling errors on the client
side and wihtout ewaiting for timeout.
New 'prompt-event' can redefine the interactive prompt with a newLISP
routine, e.g:
(prompt-event (fn () (append (real-path) "$ ")))
changes the prompt to a UNIX shell-like prompt. See manual for more
details.
New 'command-event' can specify a function written in newLISP to pre-process
the newLISP command line and newLISP server mode requests before they are
evaluated. This can be used to write customized newLISP shells, and to
filter or trasform HTTP requests when running in server mode.
(command-event
(fn (s) (if (starts-with s "[a-zA-Z]" 0) (append "!" s) s)))
UNIX commands are passed to the shell via the ! operator. Lines starting
with a parenthesis or space are passed to the newLISP interpretor.
See the manual reference for 'command-event' with more examples and
how to write a preprocessor for HTTP requests. This new function obsolotes
the old 'command-line' and old way of writing 'httpd-conf.lsp' files.
9.3.12
'series' can take lambda expression instead of number factor:
(series p (fn (x) (div 1 (add 1 x))) 20) => converges to Phi for any p != 0
synchronization in the Cilk multiprocessing interface can now be event driven
by defining a function instead of a timeout in 'sync'
Bugfixes in newlisp-edit.lsp for newLISP-GS
cleanup in nl-debug.c
restore SIGCHLD behavior after Cilk to newLISP startup conditions
using 'constant' or creating contexts on local symbols is not permitted
and causes an error message in: lambda, lambda-macro, ley, letn, letex, local

9.3.13
Better distribution with new Knuth algorithm for 'randomize'.
Several bug-fixes in newlisp-edit.lsp for newLISP-GS and new functions.
9.3.14
New functions for MIDI sequencing several tracks/channels in parallel.
See the new demo files midi-demo.lsp and midi2-demo.lsp.
9.3.15
Non-default directory install on Win32 now works. Windows must be rebooted
when not accepting the default directory, so the different path set in
the environment variable NEWLISPDIR can come into effect.
In newLISP-GS loading of external soundbanks and saving of sequences to
MIDI files and channel pitch bending. See newLISP-GS changes notes for details.
Added reference passing to some missing functions.
Cilk API for 'sync' changed handling the inlet function as an optional second
parameter.

version 2.3 does the translation correctly on UTF-8 and non-UTF-8 url-encoded
strings and on both versions of newLISP.
9.4.1 release July 6th, 2008
Filled some gaps in namespace reference passing and fixed memory leaks in the
matrix API and 'count' function (on Unix). Passes the Valgrind memory check with
0 bytes lost memory!
In parse-date the default day offset has been changed to more sensible 1 (was 0).

fixed reentrance bug in format
fixed compilation as Unix library
fixed $args losing protection under error conditions
updated gmp.lsp module documentation and library load locations
new 'if-not' works like current 'unless' which will loose the else-clause
in a future version to work like a (when (not ... ) ..)
'inc' and 'dec' on a variable containing 'nil' assumes 0 contents, this
makes initialization of variables used in 'inc' and 'dec' un-necessary,
but is also compatible with existing code
additionally to doargs, dolist, dostring, dotree now all other non-counting
iterators: map, while, until, do-while, do-until upate the internal $idx symbol,
e.g: (map (fn (x) (list $idx x)) '(a b c)) => ((0 a) (1 b) (2 c))

Reference returns
=================
Any built-in function returning a list or an array or a listelelent or array
element, will return a reference and not a copy if the list or array is bound
to a symbol. This make it possible to work on with destructive function on
on the return value of other function modifying the original list or array:
(set 'lst '(a b c))
(setf (first lst) 99)
lst => (99 b c)
(setf (lst -1) 'C)
lst => (99 b C)
(set 'A '((a 1) (b 2) (c 3)))
(push 'z (assoc 'c A))
A => ((a 1) (b 2) (z c 3))
(set 'L '(a b (c d e f g)))
(= (replace 'f (nth (+ 1 1) L) 'z) '(c d e z g))
(= L '(a b (c d e z g)))
... and similar with many other functions ...
The following functions now return a reference to the list, array or string
or element of a list or array, which can be modified by other functions.
Previously a copy was returned:
'assoc'
'first'
'last'
'lookup'
'ntn'
'replace'
'reverse'
'rotate'
'set' (returned reference already)
'setf' (new function)
'setq' (old function now working like setf)
'set-ref'
'set-ref-all'
'sort'
'swap'
'setf' is a new introduced function working not only on symbol references like 'setq'
but also on any other reference returned from an expression. 'setq' now works like
'setf' and both point to the same internal code and are interchangeable. It is
recommended to use 'setq' for setting symbol variables and use 'setf' whenever a sublist
or subarray is referenced, this follows usage in other LISPs:
(setq l '(a b c d e f))
(setf (first l) 99)
(setf (last l) 9900)
(setf (nth 3 l) 'Z)
(setf (l 3) 'z)
l => (99 b c z e 9900)
(setq l '((a 1) (b 2) (c 3)))
(setf (assoc 'b l) '(b 20))
l => ((a 1) (b 20) (c 3))
The changes make many of the involved functions faster. It also obsoletes the functions
'set-assoc', 'assoc-set', 'set-nth 'nth-set', 'ref-set'. As these function don't occur
much in average newLISP, source changes necessary in existing code are minimal.
In 55 lisp source files shipped with newLISP only 3 files needed minor changes:
modules/stat.lsp /modules/xmlrpc-client.lsp guiserver/newlisp-edit.lsp
the parenthesized syntax for assoc, nth, ref, set-ref and set-ref-all
has been eliminated. Only the traditional flat syntax is allowed. When multiple
indices or keys are used a list is specified instead of a single index or key:
(nth i myList)
(nth idxList myList)
(assoc key aList)
(assoc list-of-keys aList)
....
Index list vectors are the same as returned by 'ref' and 'ref-all'. Index vectors
have been supported with 'pop' and 'push' for several years. as befor index vectors
tie together 'nth', 'ref', 'ref-all', 'push' and 'pop' Using index vectors in the
(only) flat syntax of 'nth', give 'nth' a uniform arity regardless of the number
of indices involved.
In the 9.x.x series of newLISP support of the parenthesized syntax was inconsistent
and lead to ambiguities when using expression for the key in the 'ref' family of
functons. Parentheses in this syntax where similar to to parentheses in looping forms
like (dotimes (x N) ..) etc.. Because they where part of the syntax and not part
of the normal s-expression these forms where not suitable for 'apply', 'curry' and 'map'.
In the functions 'ref' and 'ref-all' they createted ambiguities when reading sourc
about what syntax was used the flat or the parenthesised form.
Now the flat syntax is consistenly the only syntax supported. Multiple indices are
espressed as lists (index vetors).
No changes to implicit indexing, which is conveniently used now when using setf:
(set 'l '(a b c d e f))
(setf (nth 3 l) 'Z) ; explicit
(setf (l 3) 'z) ; implicit and fastest
Other changes
=============
'unless' is reintroduced working like (when (not ...) ...) with no else clause
'lookup' now can take multiple keys like to 'assoc'
All control structures without local variables maintain reference for last return
value if that value is tied directly or indirectly to a symbol:
'begin' 'if', 'if-not', 'when', 'unless', 'while', 'until', 'do-while', 'do-until',
'cond' and 'case'. 'begin' cannot be used anymore to make a copy of an expression,
use a lambda function instead: (define (copy x) x)
the initialization file in either $HOME/.init.lsp or $USERPROFILE/.init.lsp or
$DOCUMENT_ROOT/.init is loaded if it exists, else if $NEWLISPDIR/init.lsp exists,
it is loaded
'set' and 'setq' will not allow a missing value argument as was possible before
("" 0) and ("" -1) will return "". Before ("" 1) also returned "", now will give
out-of-bounds error
added "text/css" and "application/javascript" media types for -http mode
'eval-string' has dropped the optional error-handler parameter, use 'catch' instead
(reintroduced in 9.9.4)
'read-expr' redone, simplified, more useful:
(read-expr <str-expr> [<context>]) => expr
basically works like 'eval-string' but doesn't evaluate the expression it compiles
length of string parsed is in $0
'net-eval' internal cleanup, now uses sysEvalString() like 'spawn'
Short conversion guide
======================
This is a summary of changes necessary to pre 9.9.2 lisp source code to make it
run under 9.9.2 and versions after:
- 'unless' - the new version of this function does not have an else-clause but
works like: (when (not ...) ...). If old code contains 'unless' with else-clause,
rename it to 'if-not'
- 'set-nth', 'nth-set', 'set-assoc', 'assoc-set' all have to be relaced by a
combination of the new 'setf' and 'nth' or 'assoc, e.g:
(nth-set (lst idx) value) => change to => (setf (lst idx) value)
(set-assoc (aList key) value) => change to => (setf (assoc key aList) value
- Multitple indices in 'nth' have to be put in a list and in flat syntax:
(nth i j k aList) => change to => (nth (list i j k) aList)
- 'eval-string' and 'read-expr' lost the error handler parameter, use 'catch' instead to
capture and handle errors.
- Nested expressions of built-in destructive functions must not rely on functions
returning a copy. E.g. in previous versions (pop (sort myList)), myList was sorted
but the 'pop' of the first element happened on a copy:
(set 'myList '(b d c a))
; in 9.4.5
(pop (sort myList))
myList => (a b c d)
; in 9.9.2 and later
(pop (sort myList))
myList => (b c d)
The new behavior leads to faster and more efficiently coded programs. It is also,
what many newcomers to newLISP coming from other programming languages would
expect intuitively.
- a 'set-nth' or 'nth-set' used on strings must be replaced with either a
combination of 'push' and 'pop' when working on utf-8 or ascii content or
combination of 'append' 'slice' when working on ascii or binary content.
Note that 'push' and 'pop' both can handle more than one character at once.
9.9.3 and 9.9.4
Some default functor handling was broken, giving errorneous protection messages
and bad results on contexts in 'setf'
'apply' now honors ref-returns:
(push 99 (apply set '(var ())))
var => (99)
Fixed context-symbol <-> context comparison to make assoc in FOOP more
flexible (may be quoted or unquoted in FOOP)
Fixed a stack overflow in eval-string (bug introduced in 9.4.8)
Anaphoric $it in all functions, which can do self referential expression evaluation
like: 'setf', hashes, 'replace', 'set-ref', 'set-ref-all', 'find-all'
(setf (l idx) (+ $it 1)) ; increments value
(setf (str idx) (upper-case $it)) ; upper-cases a letter in a string
(MyHash "var" (upper-case $it)) ; uppercases string in hash value
Note that the anaphoric $it is not reentrant (neither are $0 - $15) and
will forget its value after exiting the expression (unlike $0 - $15).
The functions 'replace', 'set-ref', 'set-ref-all' and 'find-all' use both $0
and $it for the same value. 'setf' and hashes use only $it.
Error procedure in 'eval-string' and 'read-expr' returned as last parameter.
Context and error procedure parameter are swapped compared to 9.4.x series
this way the error procedure doesn't need to be specified when using context
spec. Before a nil had to begiven to suppress error-handler.
A few more MIME media types have been added: css, js, avi, wav, zip.
See Users Manual.
'env' without any parameters now returns an association list, not a list of
flat strings as before:
(env) => ( ("TERM" "xterm-color") ... ("SHLVL" "1") ...)
This way 'env' simulates hash syntax in all aspects. To generate the old-type
environmnt list use (exec "env") which returns a list of environment strings
of the form "key=value".
'setf' working on indexed string references:
(setf (nth idx str) newStr)
(setf (str idx) newStr) ; faster
(setf (last str) newStr)
(setf (first str) newStr)
(setf (last s) (dup $it))
All will change the original string in s and return newStr. All can also work on
string returns of other built-in functions, i.e:
(set 's "a-b-c-d-e-f-g")
(setf (first (replace "-" s "")) (upper-case $it))
s => "Abcdefg"
translate old: (set-nth (s idx) value) ; same for nth-set
into: (setf (s idx) value)
9.9.5
'push' now returns a reference to the changed list instead of the pushed element.
Now both combinations: (push (pop ...) ...) and now: (pop (push ..) ...)
are possible. Previously this was avoided, to avoid copying the list, which now
is returned by reference, without the need to copy it. In the following exampple
a (pop (push ...)...) combination is used to model a left-moving queue in one
statement:
(set 'L '(a b c d e))
(pop (push 'f L -1)) => a
L => '(b c d e f)
(pop (push 'g L -1)) => b
L => '(c d e f g)
No code has changed in any of the modules or applications shipped with
newLISP but in many places the code could be written shorter and faster
executing as a consequence of this change.
System variables $0 - $15, $args, $idx, $it and $main-args are now documented
in the appendix for the "Users Manual and Reference".
Corrected sort-order in the reference section of the manual.
Changed enhnaced 10.0 release notes
'copy' makes a destructive function non-destructive:
(replace x (copy theList) y) ; leaves theList untouched
newLISP-GS editor fixes
9.9.6
'amb' now has reference return too
Fixes in 'env' and NEWLISPDIR detection for SOLARIS OS
Doc changes
New 'net-interface' allows selecting a default network interface card on
multihoned network nodes. In previous versions only net-listen could
specify a specific interface IP address, now a different interface card can also
be selected for outgoing communications by changing the default IP-address.
9.9.7
protection error was not traceable in 'swap' symbols
a fix for 'local' when using setf/setq on uninitialized symbols
replaced all evalChekSymbol with getDefaultOrEval
doc changes
9.9.8
fixed the reduce parameter in 'apply'
9.9.9
swapped parameters in 'write-line' syntax with device parameter coming first
as in 'write-buffer', 'write-char', etc. The return value is now the number
of characters written as in 'write-buffer'. This made changes necessary in
the following files:
examples/sqlite.cgi
examples/tcltk.lsp
examples/upload.cgi
modules/postsrcipt.lsp
modules/stat.lsp
util/newlispdoc
util/syntax.lsp
(first '()) and (last '()) now throw error as in Scheme. Before 'nil' was
returned as in other LISPs. The change makes more sense in the new v.10.0
of newLISP, where 'first' and 'last' can return a place changed by 'setf':
(set 'l '(a b c))
(setf (first l) 9)
(setf (last l) 99)
l => (9 b 99)
Leaving the old behavior would ill-define 'setf', because their would be
no place to change. The change also avoids the ambiguity of (first '(nil))
Thanks to the community for comments on this topic!
'set-locale' now returns the locale name and the decimal point character in
a list. Previously only the locale string was returned. This makes it easier
to write locale independent code containing decimal number constants.
'file-info' now can take an extra flag to report on the original instead
of the link, when the node is a link.
'integer' (removed from docs a long time ago) now eliminated. Use 'int'.
Eliminated odd symbol syntax in write-buffer, no changes where necessary
in shipped files, as the symbols was never quoted.
Code Patterns and Users Manual Reference changes.
9.9.91
The system variable $status-header can be set to a different string. Currently
"HTTP/1.0 200 OK\r\n" is the fixed response. As an example for a no response
header you would specify:
(set '$status-header "HTTP/1.0 204 No Response\r\n")
and then exit the cgi program without outputting any content.
'read-buffer' and 'net-receive' both loose the quote before the buffer
symbol. Now a context symbol for a default functor can be passed when writing
user-defined fuctions where the the buffer can be passed in/out by reference.
The change in 'read-buffer' and 'net-receive' requires taking away the quote
from the buffer symbol in the following files:
modules/ftp.lsp
examples/client
examples/finger
examples/server
examples/udp-client.lsp
examples/udp-server.lsp
examples/upload.cgi
set and inc/dec are now the only built-in functions where a quote is required before
a symbol. Correct quoting is one of the difficulties new-comers to Lisp have.
In the Reference Manual all destructive functions are marked with an excla-
mation mark "!" which links to the relevant Users Manual chapter.
All functions with special behavior on UTF-8 strings are marked as "utf8"
and linked to the relevant Users Manual section.
9.9.92
'inc' and 'dec' now don't quote the symbol and also can increment or decrement
a place in a list structure or an unreferenced (unlike setf) number:
(inc x) => 1 ; if x is nil initially 0 is assumed (as before)
(inc x) => 2
(set 'l '(1 2 3 4))
(inc (l 1)) => 3
(dec (nth 0 l) 2) => -1
(dec (last l) 0.1) = 3.9
(inc (+ 3 4)) => 8
l => (-1 3 3 3.9)
as before nil is taken as 0 before inc/dec and floats are returned whenever
the amount is specified else assumes 1 for amount and returns integers
The status header feature introduced in 9.9.91 has been reworked and is
simpler to use now. Whenever the first line output by an CGI program starts
with "HTTP/", newLISP server mode will suppress putting out the standard
status "HTTP/1.0 200 Ok" line and "Server: newLISP ..." line. Instead
*all* header information must be supplied by the CGI program. The following
example would redirect a request to a different URL:
#!/usr/bin/newlisp
(print "HTTP/1.0 301 Moved Permanently\r\n")
(print "Location: http://www.newlisp.org/index.cgi\r\n\r\n")
(exit)
works on OSX 10.5 and Safari browser
9.9.93
When answering HTTP requests, newLISP server mode sets the environment
variable SERVER_SOFTWARE to "newLISP/n.n.n" where n.n.n is the version
number. This is used to write server independent CGI programs. The same
environment variable is also written by the Apache and Microsoft-IIS web
servers.
Updated versions newlisp-ide-4.2.tgz and newlisp-wiki-4.3.tgz for 10.0.
The library newlisp.dll or newlisp.so will look for the environment variable
NEWLISPLIB_INIT and load the file specified there instead of looking for
HOME/.init.lsp or NEWLISPDIR/init.lsp. NEWLISPLIB_INIT must contain the full
path/file-name of the file to be loaded.
'write-line' with just one argument will still take that argument as a
either a file or string device to write too and write the string found
in 'current-line'. The previous (9.4.5) behaviour of writing that string to
the console is a historic relic when there was no 'println'. So the first
argument is always the device to write too.
Fixed error behavior for 'inc', 'dec'.
Many manual corrections
9.9.94
suppress loading of any init.lsp or .init.lsp using -n as the first
command line option, i.e.: newlisp -n
fixed a bug in replace when key cell is self referential
corrections in accompanying files
Users Manual corrections
CodePatterns.html corrections, separate chapter about HTTP mode.
Experimental 'estack' with variable environment history.
9.9.95
No NEWLISPDIR/init.lsp or HOME/.init.lsp will be loaded by a newlisp.dll
or newlisp.so shared library module. Only if NEWLISPLIB_INIT is defined
the full path-name contained in it is loaded, else nothing is loaded.
file:// urls now allowed on 'get-url', 'put-url' and 'delete-url'. Was documented
already for 'get-url' but never implemented.
file:// url was missing for 'delete-file'.
'save' now throws error when using http:// url just like w/o url mode. Before
the HTTP error message was returned. This allows writing error
handlers working equally on all modes specifying the file-path in 'save'
and 'load'.
fixed a crash bug when deleting a symbols containing the context of the symbol
to be deleted. Strickter syntax now for 'delete', when deleting contexts, the
symbol of the context must be given, not the evaluated context:
(delete Ctx) => must now be => (delete 'Ctx)
in newLISP console now keyword completion when hitting TAB once/twice for newLISP
built-in primitives (Mac OS X, Linux and other UNIX only).
On Linux and other UNIX .inputrc with the keyword "newlisp" will also be
recognized.
fixed indx/dec for integers when compiling for 64bit CPUs
Manual corrections
9.9.96
'write-buffer' reported a wrong parameter on error
'prompt-event' now receives the current context as a parameter
'curry' now almost 50% faster and hygienic
'integer' which has been deprecated and not documented for some time
is now eliminated, use 'int'
'default' documented again
a bug fix in infix.lsp for trailing lower priority ops
'set-ref-all' now will not overflow the stack on large lists
'bits' function for binary conversion now documented
(bits 1234) => "10011010010"
(bits 1234 true) => (nil true nil nil true nil true true nil nil true)
((bits 1234 true) 0) => nil
'inc' will throw error on missing argument
9.9.97
misc. cleanup in net-receive and net-select
updated syntax.cgi and newlispdoc to handle <? ...> XML tags
$idx gets also updated in the second syntax of the series function.
all HTML files delivered with distribution pass: tidy -utf8
HTML generated with newlispdoc and syntax.cgi passes: tidy -utf8
except when generating for gmp.lsp (special characters +,-,*,/,=,<,> in function names)
(see http://tidy.sourceforge.net)
updated newlispdoc v2.1, syntax.cgi v2.5
10.0 Release December 8th, 2008
10.0.1 Release January 8th, 2009
Eliminated warning messages for new gcc version 4.3.2 compile.
Fixed stat:plot and stat:plotXY routines in stat.lsp for gnupot. Tested
on Gnuplot version 4.2.4 on Mac OS X and Win32. The routines broke in 9.3
when process required the full pathnam for the process launched.
Documentation for syntax pattern for stat:plot was wrong. The stat.lsp
module now looks for the gnuplot executable and gives a message if gnuplot
cannot be found. The module also looks for $HOME/tmp or c:/temp on Windows.
Additional offset parameter in 'read-expr' and 'eval-string'
Allow default functors to contain FOOP objects. This allows writing destructive
FOOP procedures, e.g.:
(new Class 'Foo)
(define (Foo:modify obj val) (setf (obj 1) val))
(define (Foo:show obj) (default obj))
(set 'MyFoo:MyFoo (Foo 123)) => (Foo 123)
(:modify MyFoo 999) => 999
(:show MyFoo) => (Foo 999)
All looping functions with locals variables: for, dotimes, dolist, doargs
and dotree now can return references too. Now all built-in functions
except: let, letn, letx and local return references when possible.
Fixed potential memory leaks in the Win32 utf16 functions.
'bayes-query' produced wrong results for non-existing tokens when using
Fisher's Chi2 method
'last' on strings as reference in non-UTF8 versions always referenced first.
The link.lsp feature was broken in 9.9.95
'callback' expanded to 8 parameters and 16 callbacks
changes in examples/upload.cgi demo
redone documentation and examples for UDP communications in Code Patterns
and reference documentation
10.0.2 Release March 9th, 2009
Addition of READ_ME-OS2 in doc directory and of readline mode in makefile_os2
Treatment of trailing slashes in file-names for the 'file?' function is
now consistent with Mac OS X and other UNIX. (file? <directory-name>)
should always return true, regardless of trailing slash
'sys-error' now returns last OS errno and text in a list similar to net-error
(sys-error 0) resets (as before), any other number reports the error text
overhaul of makefiles for linux/debian and naming of some osx makefiles
make linux
or
make debian
will allways compile a 32-bit newLISP even when on 64-bit Linux. This is the
preferred mode to compile for linux, as most libraries and other apps run
an 32-bit API even if the OS is 64-bit. Same is true for OS X. This gives
newLISP 4G of workspace, with integer operations and file positioning 64-bit.
Only if newLISP has access to more than 4G of memory it makes sense to compile
fully 64-bit using one of the makefiles with '64' in the name.
added two amalgamation makefiles in the util directory for Darwin and Linux,
no advantage over normal compile, but perhaps different results on other
platforms,
new 'read-utf8' like 'read-char' but reads multibyte utf8 chars
'eval' did only pass symbol references, now also references from indexed
expressions:
(define-macro (foo) (list (args 0) 0))
(setf bar '(1 2 3))
(foo bar) => (bar 0)
(setf (eval (foo bar)) 3) => 3 ; was not possible before
bar => (3 2 3)
The "Status:" response line for CGI processing has been redone. When newLISP
server mode sees CGI output starting with Status: it will compose the HTTP
status header with the rest of the line appearing after "Status:" in the line.
See the Code Patterns document for an example.
Eliminated all references to opsys (OS number from sys-info) in favor of
Labels "Linux", "Win32" etc. in qa-xxxx files and added "AIX" for future
makefile_aix and makefile_aix_utf8 .
10.0.3
Expanded 3rd syntax in 'swap' (swap <place-1> <place-2>) The first two old
call patterns are deprecated and will be removed in a future version.
Eliminated a stacksize dependence when using 'find' with 'match'
IBM AIX for PPC has been added as a platform and using the IBM xlc_r or gcc
compiler. Some issues with newLISP server mode are not resolved yet.
Fixed a memory mapping problem surfacing on IBM AIX 32-bit compiles
Better handling of status in HTTP headers sent back from server
'nil' and 'true' confused 'sort' and 'unique', fixed.
10.0.4
Improved precision and shorter source for 'prob-z' function
'expand' and 'letex' now also expand a top-level symbol not in expr list or
quoted:
(set 'x 123 'y 456)
(expand 'x 'x) => 123 ; threw error before
(letex (x 'y) x) => 456 ; returned y before
(letex (x '(+ 3 4)) x) => 7 ; returned (+ 3 4) before
previously some of these caused an error in 'expand' and did no expansion
in 'letex'
Definition of 'legal?' for symbols was to strict
10.0.5
makefiles for 64Bit Linux missed the NEWLISP64 flag since 10.0.2
added makefiles for BSD LP64 mode
code cleanup for OpenBSD warnings
new 'xfer-event' can monitor byte-transfer in get-url, post-url
and put-url and all file operations which take URLs.
(xfer-event (fn (n) (println "->" n)))
(length (get-url "http://newlisp.org"))
->10240
->11221
11221
'write-buffer' now behaves like 'write-line' when supressing second or
first parameter
new 'last-error' replaces 'error-number' and 'error-text' and returns
number and text in a list consistent with the behavior of 'net-error' and
'sys-error'. All three now behave the same way and can enumerate all
errors when given the error number as parameter.
'bind' did not allow recursive definitions
10.0.6
some HTTP net errors where not registered with 'net-error'
readline tab expanson formatting was broken in 10.0.5
fixed a bug in 'replace' remove mode when all list members are nil
lambda functions (not lambda-macro) now allow for large or infinite
running bodies without stack impact
10.0.7
'net-lookup' now sets 'net-error' when lookup fails
Miscellanous cleanup in nl-sock.c
Two NaNs should compare nil, division by zero will throw a div-zero-error
now only in integer division (/) with floats (div) it will return inf(inity).
New 'inf?' tests for inifinity: (inf? (div 1 0)) => true
now (NaN? (div 0 0)) => true
Thanks to Nelson H.F.Beebe from math.utah.edu to point out the correct IEE-754
behavior for division by 0.0, and NaN? and inf? tests.
The build process now also accepts 'make check' additionally to 'make test'
for GNU compatibility: 'make all check' and then 'sudo make install' makes
tests and installs.
When installing using 'make install' or when installing from the UBUNTU Linux
binary installer a newlisp-x.x.x (where x.x.x is the version number) and a i
symbolic link is created for newlisp -> newlisp.x.x.x. This way older versions
stay and are still accessible. The binary installers for Win32 and Mac OS X
have not changed.
The newlispdoc utility now accepts custom tags, which can be made up by just
prepending the custom name with a: @. The text after the custom tag will be
translated as usual, e.g. it may contain @link tag etc.. Like in most other
tags, text is limited to the same line.
10.0.8
'pack' now converts floats to integer when the format is integer but the
argument is a floating point (double). It already converted integers to float
when the format was float, but didn't handle the other direction.
(int "ff" 0 16), (int "+ff" 0 16) and (int "-ff" 0 16) now all work. In former
versions a leading 0 or 0x was required.
An optional boolean flag in 'dotree' allows filtering hash symbols or symbols
from 'bayes-train' starting with an underscore character in their name.
Small fixes for syntax highlighting in newlisp-edit.lsp.
newlisp-edit.lsp now can change fonts in both, the editor and monitor areas,
depending on cursor position.
The syntax highlighter in syntax.cgi and newlispdoc now colors newLISPdoc
tags too.
10.1.0 - release June 22nd, 2009
fixed a memory leak in 'sync' when transferring data bigger memory page-size
(add) and (+) now return 0 and (mul) and (*) return 1. Before a missing
parameter error occured.
(and) now returns true. Before it returned nil. (or) still returns (nil).
new 'send' and 'receive' message functions for communications between
parent and 'spawn'ed child processes. Transfers any expression any size.
new 'qa-message' file for testing new 'send/receive' message functionality
Makefiles with 'solaris' have been renamed to 'sunos' and the built-in
variable 'ostype' now reports "SunOS" for Sparc SunOS and "Solaris" only for
OpenSolaris. Before "Solaris" was reported for all.
All UNIX except AIX and TRU64 are now compiled for readline and UTF-8 support
by default: make. Do make -f makefile_xxx. to choose a different configuration.
The util/ directory contains an alternate configure script called configure-alt
this can be copied up to the main distribution directory as an alternate
comnfigure utility. See util/configure.txt for more info on this.
if an 'until' or 'do-until' body is empty the last condition evaluation
should be returned
10.1.1 - release update July 21st 2009
'string' function now 25% faster on expressions
It is not necessary anymore to give the program expression in 'net-eval' as a
string, if not given as string net-eval will convert automatically:
(net-eval "remote.com" 12345 "(+ 3 4)") => 7
; same as
(net-eval "remote.com" 12345 '(+ 3 4)) => 7
Same works for the nested syntax with map of sites and expressions.
Added optional offset parameter in 'regex' and 'find' (in string syntax)
(regex <pattern> <string> [option [offset]])
'series' with the function argument now can make series of any data type
'swap' was not throwing error when second parameter was missing
Fixed a bug in 'eval-string' when the error procedure was specified.
In newLISP-GS gs:color-tag was documented but not implemented in Java
In newlisp-edit.lsp (newLISP-GS IDE) Ctrl-x/v/z/Z and Cmd-x/v/z/Z did not
set the buffer-dirty red light
New 'configure' makes old 'build' script obsolete. After extracting the source
distribution, simply 'make' will look for a 'makefile_configure' and generate
it calling 'configure' if it doesn't exist, then it builds the newlisp excutable
using 'makefile_configure'. An alternative: configure-alt can be found in the
main distribution directory. See doc/INSTALL for more details.
SunOS makefiles now have support for readline by default
makefile_linuxLP64_urf8 had nl-utf8.o missing in OBJS
makefile for ARM CPU on Nokia N810 tablet. To make for ARM:
make -f makefile_linux_maemo_armel
New module smtpx.lsp like smtp.lsp but allows attachments
10.1.2 Windows only release update , August 3rd, 2009
to correct printing to stdout problem
10.1.3 development release Aug. 9th, 2009
'inf?' and 'NaN?' where not working correctly on Win32, a new qa-float
can be used to check several aspects of IEE 754 Floating point compliance
regarding inifinitive and NaN (not a number) floating point values.
In 'now' the last 2 fields "minutes west of UCT" and "daylight savings"
are now working correctly on Linux, Mac OS X, SunOS, BSDs and Win32.
Daylight savings on Win32 as minutes on all others as 0 to 6 flag depending
on geographical area. On AIX, OS2 and TRU64 0 is returned for both fields.
The 'time' function now returns float milliseconds with fractional part
instead integer milliseconds.
The return string size from 'command-event' is now unlimited, before
254 length was maximum.
New -t <connection-timeout> commandline option, specifies timeout in
micorsoseconds after connection when in demon mode. This avoids an un-
responsive server when a client connects, but doesn't do anything else.
New makefile_darwin_utf8_llvm on OSX for building newLISP using the LLVM
compiler. Improves performance by about 10%, needs developer tools installed.
New versions of syntax.cgi and newlispdoc correct highlighting for & and ^.
New version of nls (combined newLISP and BASH shell) adapts the help function
to the manual formatting introduced in 10.1.1.
Long overdue removal of internal cell mark/sweep routines.
Net sessions list now avoids socket doubles in server mode.
10.1.4
'now' offset parameter crashed broken in 10.1.3, working again
10.1.5 Maintenance Release September 15th, 2009
Fix for OS2 compile in nl-filesys.c
Fixed stray i in fetch-all in mysql.lsp,
Return milliSec float with decimals for 'time-of-day'; on modern systems
this enables microsecond resolution.
On Mac OSX 10.6 Snow Leopard, the make/configure script will make a 32-bit
newLISP although 64-bit is detected as the default. To make 64-bit newLISP
use one of the supplied makefiles explicitly as in earlier Mac OSX versions.
Copying a zero-length file will not throw an error anymore.
10.1.6 Maintenance Release October 20th, 2009
Fixes for 'net-error' and 'sys-error' when supplying out-of range numbers
o 0s.
Documentation fixes in the 'Users Manual and Reference'.
'inf' is now signed in floating point opertions: (div -1 0) => -inf
'mod' will return NaN for a 0 divisor, % will still throw an exception
when divisor is 0.
Fixed a memory bug in 'starts-/ends-with' when using regular expressions.
'nil' and 'true' symbols where not always taken as boolean value which
affected 'sort' and 'difference'.
New 'reader-event' triggers when an expression was read. The function
specified in 'reader-event' can translate the expression before
evaluation returning a modified version of the input. This can be used
to create a reader macro facility.
New module file macro.lsp implements reader/rewrite macros by means
of the new 'reader-event' function.
Change in sqlite3.lsp in bind-parameter, how text and blobs are retrieved.
deprecate usage of $0 in set-ref and set-ref-all .
throw error when trying to do a replace on a system symbol
some cleanup of itSymbol
10.1.7 maintenance release November 24th, 2009
URLs now decoded correctly when compiled in IPv6 mode.
IPv6 compiled version now runs qa-net.
'net-ping' does not require root/superuser privileges anymore when on Mac OS X.
Small speed improvement in map and fixing treatment of missing arguments:
(map list '(a b) (A)) => ((a A) b) ; not ((a A (b nil))
(map string '(a b) '(1)) => ("a1" "b") ; not ("a1" "bnil")
'swap' can work in-place like: inc, dec, pop, push, replace, rotate, sort,
write-buffer and write-line always could.
Optional true-flag parameter in ref/ref-all returns item(s) found instead of
index vectors when a compare function is specified. Instead of:
(map mylist (ref-all pattern mylist match)
do:
(ref-all pattern mylist match true)
Bad application of errorProcExt2() in netReceive() could crash on error.
Protect local symbols in caller hierarchy from 'constant' and 'context'.
All event fuctions now can take either nil or 'nil (quoted) to disable an
event handler, before only quoted 'nil was working, unquoted nil could crash.
Removed experimental 'estack' from code and newlisp.vim (introduced in v9.9.94)
Throw reference error in 'setf' on string when base ptr is not from sub-expression
string. Wouldn't do anything before.
Accept chars > 127 in HTTP headers received from remote servers in web functions.
Do URL translation of path-file names in HTTPD server mode.
A 'sql3:colnames' function has been added to the sqlite3.lsp module.
Dec 6, 2009
10.1.8 This development version starts the v.10.2 generation of newLISP
Fixed a bug when replicating primitives with 'new'.
FOOP objects are now mutable, anonymous or not. The old obj parameter has been
dropped from FOOP methods. Instead a new function 'self' is used to access and
index the target object:
(new Class 'Circle)
(define (Circle:move dx dy)
(inc (self 1) dx)
(inc (self 2) dy))
(set 'aCircle (Circle 1 2 3))
(:move aCircle 10 20)
aCircle => (Circle 11 22 3)
Old FOOP methods have to be rewritten to drop the obj parameter:
old : (define (Foo:method obj p1 p2) ...)
new : (define (Foo:method p1 p2) ...)
This has also reduced the overhead required in FOOP methods. Allthough this
change creates an incompatibility with older FOOP code, the advantage
of having mutable objects compensates for that incompatibility. Destructive
methods was the FOOP feature most asked for ind newLISP.
10.1.9 Jan 12, 2010
Fixed executeCommandLine() for 64-bit UBUNTU, which could cause writeStreamStr()
related functions to crash.
(delete <sym> nil) will delete symbols without checking any references. The
symbol can be a context symbol. Note that this mode of 'delete' can crash
the system if if symbols are referenced from anywhere else.
Fixed double evaluation in nil? predicate
Fixed a bug in 'legal?'.
Better error reporting for url based file operations.
A sign-extension fix for 'get-int' under 64-bit
Fix in gmp.lsp for 64-bit >,<,>=,<= but still problems with 'factor'
Fix for push on fresh symbols. Did return the element pushed not the list.
Fix for push -1 optimization when copying contexts with 'new'
Fix for a memory leak in certain applications of 'new'
Fix for 'self' in nested FOOP functions, also eliminated FOOP stack
New smtpx.lsp module for (multiple) attachements and UTF-8 safe encoding
10.1.10 Jan 26, 2010
New 'extend' works like 'append' but modifies first list or string
parameter.
New ++ and -- increment/decrement in integer mode.
Functions 'inc/dec' now always work in floating point mode.
In 'find' the regex option can be specified as nil when offset is present,
this way 'find' with offset does not have to be a regex search.
In 'starts-with/ends-with' nil is not allowed as a parameter for
case insensitivity anymore use the regex option 1 instead (nil always
did regex anyway).
Changed configure-alt now allows defintion of different install and
exe prefixes. For questions and support for configure-alt, please
contact Ted Walther: ted@reactor-core.org.
Makefile has been simplified and the install part extracted as:
makefile_original_install, (used by configure).
10.1.11
Various documentation fixes and changes.
Additional, optional list-index parameter in 'now' makes it return a list
member instead of the whole list:
(now 0 0) => 2010 ; year
(now 0 -2) => 300 ; offset west of GMT (in EST)
A string slice offset out of bounds now throws error as in lists.
'pretty-print' can addtionally define the default print format for
floating point numbers.
New 'prefix' returns the context of a symbol.
New 'term' replaces deprecated 'name'.
New 'caller' returns the symbol of the caller function.
'read' and 'write' may be used as shorter writings of the elementary
'read-buffer' and 'write-buffer' I/O functions.
Addtional chapter in doc/INSTALL for package creators and installation
customization.
Updated syntax highlighing for nano, joe, and vim editors.
Added back cleaning into 'make dist'.
Re-added Cygwin flavor with 'make -f makefile_cygwin'. The make file gets
also chosen by 'configure' and makes a newlisp.exe, but has to be installed
manually together with cygwin1.dll in %NEWLISPDIR%; on Win32 normally
defined as C:\Program Files\newlisp.
Many thanks to Niek from http://daansystems.com for helping with this.
10.1.12
Symbol protection for containers of mutable FOOP objects
Functions 'crit-chi2' and 'prob-chi2' produced value too low on odd degrees
of freedom. 'bayes-query' in Chi2 mode was not affected.
moved most qa-xxx files into qa-specific, only qa-do and qa-comma stay in
main source directory. The commands 'make test' alias 'make test' work like
before, but now taking qa-xxx files from qa-specific. A new 'make testall'
can be used to test with allmost all qa-xxx files.
To reduce output do: make test | grep '>>>>>'
Rework of setf for in-place changes.
'caller' introduced in previous development version 10.1.11 has been
eliminated.
'define-macro's (fexpr's) are now included in error reporting:
define (foo) (bar))
(define-macro (bar) (+ a s f))
(foo) =>
; in older verssion 'bar' doesn't show
ERR: value expected in function + : a
called from user defined function foo
; now 'bar' is reported
ERR: value expected in function + : a
called from user defined function bar
called from user defined function foo
In newLISP-GS on Win32 a messagebox pops up if a connection cannot be
established between the newLISP process ad Java GUI server.
10.2.0 stable release March 16th, 2010
new 'configure-alt' fixes a problem for debian package making.
The enviroment variable REQUEST_METHOD is now set by newLISP server mode
to one of the strings GET, HEAD, PUT, POST, DELETE.
'det' and 'inv' now return 'nil' on singular matrices, but fall back
to the old behaviour when specifying a new optional 'true' flag. With
the flag pivot elements of 0 will assume a very small value as in
older versions of newLISP.
'xml-parse' did ot parse UTF-8 chracters correctly.
'make test' and 'make testall' now by default do the short display
with only the end result. 'make check' and 'make checkall' produce
the long output.
Fixed wrong error message in context creation.
The int-type field in all financial functions is optional.
10.2.1 stable release March 17th, 2010
'setf' and 'swap' could change the values of 'true' and 'nil'.
10.2.2
'time' did overflow after 35 minutes now can count to about 68 years.
Speed up of Hash deletion with: (<tree> <token> nil). No reference
checks are made. This means that tree hashes should only be used as
such and symbols not be referenced directly with the prepended
underscore, as is usual practice already, or be deleted explicitely
using 'delete'.
'xml-parse' with context option did not convert names of built-in
primitives.
New second syntax pattern for 'net-service':
(net-service <port> <protocol>) => service-name
(net-service 22 "tcp") => "ssh"
10.2.3
The 'net-connection' functons now can take a timeout ms parameter:
(net-connnect <str-host> <int-port> <int-milli-sec>)
on UNIX the function will fail returning 'nil' before the timeout
expires. On Win32 the 'net-connect' will not fail until the timout
is run out. This makes the function return 'nil' on closed ports
much faster on UNIX.
New documentation for 'net-service' and 'net-connect'
10.2.4
'find-all' will not exit anymore on loop conditions but retry
incrementing the the search offset by 1.
'load' in HTTP mode did not return to previous context, but always
went into MAIN.
"file://C:/example.txt" and "file:///C:/example.txt" both forms are
now valid on Win32.
On Win32 negative Inf lost the sign when converting to maxint
Shorten p_setLocale() code.
A fix for ref-passing out of loop primitives.
10.2.5
Additions, modifications to qa-xxx files
The 'true' flag in 'delete' was not handled correctly since 10.2.0
10 times speedup of 'save'
new 'net-packet' function, UNIX only tested on Mac OSX 10.4 PPC G4,
Mac OSX 10.6 Intel, Linux UBUNTU 9.10 (root privileges required).
See newlisp-10.2.5/qa-specific-tests/qa-packet for working TCP examples.
Change target IP numbers in packet examples in qa-packet to working ones.
Protocols TCP, UDP and ICMP have all been tested on OSX X PPC, OSX Intel
and Linux UBUNTU 9.10 communicating with raw packets between Big-Endian
and Little-Endian CPUs, sending a raw-packet and receiving a correct
response packet.
handling on short lists when mapping strings now consistent:
'map' stops collecting as soon as one argument list is short. This
ensures that elements in the nth row appear always in the nth column
after the transposition caused by 'map'. This was working on lists
but did not work accordingly on strings.
10.2.6
In 'get-url' the "list" option in combination with the "debug" options
did return a string instead of a list.
'net-packet' now also works with OpenBSD addtonally to: Mac OS X on
PPC and Intel and Linux on Intel CPUs.
The timeout parameter in 'get-url', 'post-url' and 'put-url' did not
work correctly since 10.2.3 after introducing the 'net-connect' timeout
parameter.
OpenBSD 4.6 now added as a regular test environment additionally
to Mac OSX, FreeBSD, UBUNTU Linux, SunOs Sparc and Windows XP/7.
10.2.7
In 'pmt', 'ipv', 'nper' int -> long for Linux 64-bit
Cell leak in 'find-all' when new handling of looping condition (v.10.2.4)
Fixes in qa-net for IPv6
Note, that net-packet is currently coded only for IPV4
Fixed a bug in URL parsing for IPv6
'find' did not evaluate regex option parameter since 10.1.10
10.2.8 stable maintenance release May 20th 2010
Backed out some IPv4/6 changes in 10.2.7 reverting to 10.2.6 plus some
IPv6 fixes. Next development version will split up nl-sock.c into UNIX
and Windows versions; recoding the UNIX version using getaddrinfo() and
getnameinfo() for dynamic IPv4 and IPv6 support in the same version.
10.2.9 development release May 27th, source only
Large portions of nl-sock.c have now been re-written to switch between
IPv4 and IPv6 during runtime using the new 'net-ipv' function:
(net-ipv) ; show current protocol as 4 and 6
(net-ipv 4) ; switch to IPv4
(net-ipv 6) ; switch to IPv6
By default newLISP starts in IPv4 mode, to start up in IPv6 mode:
newlisp -6
When the IPv4 to IPv6 transition is completed in a few years, the
default will be changed to IPv6 and a 'newlisp -4' startup option
will be introduced. The current -6 option is only necessary when starting
newLISP in server mode. In normal mode a (net-ipv ...) code switch can be used.
The nl-sock.c uses the newer POSIX 'C' getaddrinfo() and getnameinfo()
functions. Wondows 95 is not supported anymore. The minimum MS Windows version
for newLISP is now Windows NT 5.01. This allowed mostly similar code
on Windows and UNIX and made a split into platform dependent files unnecessary.
New 'qa-specific-tests/qa-net6' for IPv6 testing included in:
make testall
UNIX like OSs test fine on IPv4 and IPv6. Currently I have no IPv6
capable MS Windows, FreeBSD and SunOS installations for testing.
But on all platforms this version compiles and links well.
Following systems test fine:
Mac OS X 10.6, IPv4 and 6, 32 and 64-bit
Windows XP SP2, IPv4 only, 32-bit
Linux UBUNTU 10.4, IPv4 and 6, 32-bit
OpenBSD 4.6, IPv4 and 6, 32 and 64-bit
FreeBSD 7.2, IPv4 only, 32-bit
SunOS 5.8 on Sparc Ultra-2, IPv4 only, 32-bit
10.2.10
Allow binary zeros in 'exec' piped-in data
Cleanup for sendHTTPpage()
Fixed a bug in 'copy', which passed on a wrong protection status, when
copying protected variables since 10.1.12
IPv6 not currently working on the Win32 MinGW compiled version
Changed winsock initialization to v.2.2
10.2.11
Windows versions now compiled using wspiapi.h in nl-sock.c. This guarantees
working of freeaddrinfo(), needed for IPv6, on some older Win 2000 systems.
New multiline mode on the commandline, without using [cmd], [/cmd] tags:
just hitting [enter] on an empty line gets into and out of multiline mode.
The [cmd], [/cmd] still work too and are needed internally when newLISP is
working in server mode, for some IDEs and when pasting source containing
empty lines into the terminal. Tab-expansion (on Unix only) for built-in
function names also works in multiline mode.
Minor changes in version 1.37 of the Java based Guiserver.
In 'net-ping' specify optional third parameter to get an error string instead
of response time, if the host did not respond. This behavior was present in
previous versions, but was not documented.
10.2.12
Fixes and additions for newLISP-GS guiserver.jar. See guiserver/CHANGES
10.2.13
More fixes in guiserver see guiserver/CHANGES
no changes in newlisp interpreter
New 'date-list' returns list of year, month, day, hours, minutes, seconds from
time value in seconds since January 1st, 1900 (reverse of 'date-value')
'date-parse' is new name of old 'parse-date'
The week-day value in 'now' and the new 'date-list' has been changed to
conform to the ISO-8601 standard (international standrad for time and date
related data). Now 1-7 for Monday thru Sunday.
Font size in syntax.cgi now bigger on iOS devices iPad and iPhone
newlisp_manual.html, CodePatterns.html, ExpressionEvaluation.html and
MemoryManagement.html are now XHTML 1.0 Transitional compliant.
New users manual chapter "3. Interactive Lisp mode" explains all the
features of the read-eval-print-loop (REPL) in newLISP.
Guisererver: Fix in TextShape.java to fox crashes when painting canvas.
10.2.14 Development Release Sept 2nd, 2010
10.2.15
Increased maximum length of command-line to 511. This affects the interactive
command line and line length in HTTP request headers.
Default connection timeout set to 10 secs, up from 3 secs. Always can be
overwritten by timeout parameters in net-connect and get,post,put and
delete -url functions.
The boolean flag in 'title_case' in non-UTF8 versions was not calculated
correctly.
All HTML files in the doc directory are UTF8 and XHTML 1.0 Trans. compliant.
Additional parameter in '!' on MS Windows can be used to enter process creation
flags, e.g. for suppressing creation of a command window. Not using the parameter
assumes the old '!' method. When the parameter is present (can be 0) an alter
native method of process creation is used without dependence on a command shell
window. On Unix this parameter is ignored.
Fixed a bug in symbol compare routines when comparing dynamic symbols.
Result of 'map' should always be unprotected.
More adjustments in switchable IPv4/6 mode.
Last sys-info field should change 7th bit (512) with 'net-ipv'
A change in guiserver.lsp to fix instabilities when gs:check-event was called
from gs:listen invoked event handler functions.
10.2.16
New table widget and supporting functions in Guiserver.
10.2.17
Fixes in error handlers of xmlrpc-client.lsp and xmlrpc.cgi
Fixes in guiserver.jar in Table UI
The sniff and scan utilities are added to newlisp-x.x.x/examples
directory in the source distribution.
On 64-bit versions 'date' and 'date-value' will work for dates year 2038
and up to January 2100.
The 'mod' function assumes the second parameter to be 1 if missing, thus
returning the fractional part of a number.
Updates to configure-alt for Windows 7.
POST with multipart/form-data content-type now works with newLISP HTTPD
and CONTENT_TYPE is added to the environment by newLISP server.
now added.
10.2.18
'extend' will take an un-initialized variable and create a list or string
depending on the second argument (similar to 'push'). Before a variable
in the first argument had to be initialized to a string or list.
Added path for Fedora Linux in mysql.lsp
PCRE was not configured correctly for utf8 when using configure-alt.
pcre-config.h now includes config.h when using configure-alt to build.
Builds with the standrad configure where never affected.
versions.
Added a "divert" option to 'net-listen'. In this case a IPPROTO_DIVERT
option is added to a raw socket. 'net-receive-from' and 'net-send-to'
are used to serve the divert-socket returned by 'net-listen'. The
interface address is given as an empty string for INADDR_ANY.
BSD 'ipfw' or Linux 'ipchains' rules must be defined in the configuration
of the FreeBSD, OpenBSD or Linux platform for the divert-port and the
ports to be diverted. 'net-receive-from' will contain the local interface
address for incoming packets and will contain 0.0.0.0 for outgoing packets.
See the man page for divert. The same address received by 'net-receive-from'
is used in the 'net-send-to' call when re-injecting the packet:
(set 'divertSocket (net-listen divertPort "" "divert"))
(until (net-error)
(set 'rlist (net-receive-from divertSocket maxBytes))
(set 'buffer (rlist 1))
; buffer can be processed here before reinjecting
(net-send-to (rlist 0) divertPort buffer divertSocket)
)
newLISP must be run in superuser mode to be able to create divertSocket.
Some internal cleanup for p_first(), p_last()
Bug fixes for modules/json.lsp
Fixed cell leaks when 'ref', 'ref-all' failed with error in
compareFunc()
The return value for 'ref' has changed from () to nil, when not
finding anything.
Fixed cell leak when 'setf/q' failed with protection error
symbolCheck cleanup in 'assoc', 'lookup', 'ref', 'set-ref' and all
flow constructs results in some speedup for these functions.
10.3.0 Stable Release, February 2nd, 2011
newLISP HTTP server now also sets CONTENT_LENGTH environment
variable when present in incoming client header.
In cgi.lsp added (outcommented) alternative method for reading
POST data. This relies on CONTENT_LENGTH set in the environment.
Fixed a problem in assoc, lookup and pop-assochen nil is passed
as key.
cgi.lsp now uses CONTENT_LENGTH if present to receive POST data
Fisher Chi-2 derived probabilities in bayes-query are not normalized
any more.
10.3.1 development release May 17th, 2011
Documentation changes
When a list reference changes while being indexed an error is thrown.
Code written this way will normally not make sense, but now fails
more gracefully.
(set 'lst '(1 2 3 4 5))
(lst (set 'lst '(1 2 3)))
---> ERR: list reference changed
MBCS coded characters in pathnames in the Windows UTF-8 version.
Better worded error message when wrong parameter type in implicit
indexing of strings and lists.
Fixed a buffer overflow for interactive multiline mode for long
input lines.
Fix for 'filter', 'index', 'clean', 'exist' and 'for-all' when
handling empty list elements (). Also, these functions are now
several times faster.
Check for missing parameter in inc, dec, ++, --. Using these
without any parameter messed up the value of 'nil'.
Fixed crash bug with boolean 'true' parameter in 'dotree'
Minimum SDK changed to 10.5 Leopard for makefiles:
makefile_darwin_utf8_leopardPPC
makefile_darwin_utf8_leopardIntel
to make a universal Tiger 10.4 based version the file:
makefile_darwin_universal_utf8_compat
still exists (for questions about this -> Greg Slepak).
bug fix for 'timer' when using recursively and not using symbols
but lambda expressions, e.g.: (timer foo 1) instead of (timer 'foo 1)
when the (timer ...) statement is part of foo.
New version 0.3 of json.lsp module now processes backslashed characters
as of JSON spec (thanks Ted Walther).
Speedup and memory lossless error recovery in 'map'.
Better memory management in error recovery of evaluateStream()
and sysEvalString()
Did not clear EOF error in 'read-line'.
10.3.2 stable maintenance release July 20th, 2011
New 'debugConsole' in newlisp.dll can be imported and called for
re-opening std I/O to CONOUT$ and CONIN$.
Fixed memory leak in library mode.
Doc changes and additions.
makefile_darwin_utf8_lib for newlisp.dylib
Fix for "debug" option in 'get-url' when passing url-encoded
strings (thanks to Kosh for catching and fixing this)
The newlisp.1 man page showed an old invalid method to define
redirections in http-conf.lsp.
Significant speedup of 'series' with function in second argument.
Speedup of 'find-all' (for lists and strings) when function is used
as third argument.
Quoted strings now can contain unicode characters encoded using
\u.... , where .... are four hex digits e.g. "\u03b1\u03b2\u3b3"
for the Greek letters "αβγ" (alpha, beta, gamma). When reading
the string, newLISP will translate it to UTF8 encoded characters
on UTF8 enabled versions of newLISP.
More work on 'map': speedup now also on smaller lists.
Avoid redundant cellCopy() when cell already on result stack
(needed change in array initialization).
Fixed and error message in gs:save-sequence
10.3.3 stable maintenance release September 20th, 2011
Manual updates.
On MS Windows newlisp.dll now lives in windows/system32 or whatever
the main 32bit DLL directory is on the specific Windows platform,
chosen by the $SYSDIR variable in the NSIS installer.
Fixed broken memory sharing for date sizes > 4084 bytes.
This affected 'spawn' and 'share' for memory transfers > 4084 bytes.
Also inlined stream writing for this fucntion again for better
memory cleanup.
Share file in tmp is now deleted when unmapping under UNIX. Unmapping is
not available in Windows but in all OS a (share mymem nil) will
always delete any existing tmp file for this share.
When in trace/debug mode and an error occurs in a function call
inside a 'catch' statement, an error message will now be printed,
Processing will continue as before with the offending function
returning either 0 or nil depending on the nature of the function.
This allows to inspect the current state of the program.
2 new example programs in newlisp-10.3.3/examples/ :
Script 'async' show how to do asynchronous web page retrieval.
Script 'query' shows how to retrieve 20 pages in parallel spawned
child processes.
Fixed return value from callback funtions when 64-bit integers
are returned.
From newLISP library a new function "newlispCallback" can be imported
to register callback functions (see manual for details)
-l -L now always create a logfile if it doesn't exist. Evaluation
results prepended with "-> ". [cmd],[/cmd] are not logged
Save memory in 'string' and 'format'.
10.3.4
Reworked 'send'/'receive' message API is multiple times faster and has
more consistent performance on different platforms. Better on BSDs
than on Linux. The channel for each child is now a dual read/write
message queue. In previous version only one message could be written
to the queue with send, now mutiple message can be send on the same
channel and retrieved on the receiving side with multiple 'receive'
until returning 'nil'.
In the new syntax of 'receive' the <message> parameter is optional:
(receive <pid>) ; returns the message or nil
(receive <pid> <message>) ; returns true or nil
Both 'send' and 'receive' now have syntax to return a list of all
ready child channels using either (send) to get a list of child
pid's ready to receive data or (receive) to get a list od child
pid's ready to be read. This greatly speeds up asyncrounous
messaging, where multiple child processes, but not all, have sent
messages. Previously:
(dolist (p (sync)) (until (receive p msg))) ; (sync) -> child pids
Now using only a ready subset, 'receive' can be used non-blocking
and only a subset of all child pids is iterated through:
(dolist (p (receive)) (receive p msg))
Now, when a 'spawn'ed child process ends abormally the variable in the
spawn command will contain an error message and a result number,
e.g. '9' from a kill signal sent by an external process.
Fixed longstanding bug for list-mode 'net-select'. Now returns
socket numbers in the ready list not 0's.
Documention for the messaging API has been updated in the reference
manual and code patterns documents.
10.3.5
'invert' over-allocated memory
Fixed a crash bug in purgeSpawnList()
icmp6.h include for cygwin in nl-sock.c (thanks KOSH)
The creation of a communications channel between and parent process
and 'spawn'ed child processes for usage with the message API of
'send' and 'receive', is now optional:
(spawn <sym-variable> <child-process> [true])
If the'send' or 'receive' is used on the child process spawned, the
optional flag must be set to 'true'.
The fakes versions on 'spawn', 'sync' and 'abort' in Win32 have been
taken out.
The newLISP shell "newlisp-x.x.x/util/nls" now works on MS Windows too.
The link feature using util/link.lsp did no works with 64-bit versions
of newLISP.
In the MinGW compile of nl-sock.c the include file wspapi.h has been
replaced with ws2spi.h. This file is part of the normal MinGW install.
newlisp.dll now lives in NEWLISPDIR again as it did before 10.3.3
10.3.6 development release November 18th, 2011
Speedup of string stream conversion for 'format', 'string'.
A bug fix in 'spawn' when aborting child processes
Preparations for expanded FFI (grep for FFI in all files)
10.3.7 development release
Fix in printing FFI primitives (FFI is disabled by default)
Updated newlispdoc now all tags (including custom) are title-case'ed
Simple libffi calls working on Mac OSX, UBUNTU Linux (Intel) and Win32
three (and more) new ffi makfiles:
makefile_darwin_utf8_ffi # std OSX install has libs and headers
makefile_linux_utf8_ffi # must install package libffi-dev
makefile_mingw_ffi # must install libffi.a library for build
New qa-specific-tests/qa-ffi for ffi API testing
The new ffi extension work with the existing 'import' functon:
(import "libc.dylib" "atof" "double" "char*")
(atof "123.456") => 123.456
No "cdecl" or "stdcall" mustbe specified. The parameter after
the function name is the return type. The remaining parameters
are the function arguments.
As before, the imported function can be renamed:
(set 'strtof (import "libc.dylib" "atof" "double" "char*"))
(strtof "123.456") => 123.456
The following types are implemented for LP64, LLP64 and ILP32
"byte"
"char"
"short int"
"unsigned short int"
"unsigned int"
"int"
"long long"
"float"
"double"
"char*"
"void*"
For pointer return values "char*" and "void*", the address
is returned as a number. Use 'get-string' or 'unpack' to retrieve
contents. This method allows returning binary info. THIS IS CHANGED
IN 10.3.9 where "char*" returns a string directly and "void*" a number.
10.3.8
Make sure FFIMPORT struct memory gets freed when doing multiple
'import' of the same function or deleting the func symbol.
When using 'configure' and 'make' FFI will be chosen by
default on Mac OSX, Linux and Windows (MinGW)
Both "char*" and "void*" accept either a newLISP string buffer or an
address number as input. On return "char*" will return a newLISP
string buffer and "void*" will return an address number.
Comprehensive qa-specific-tests/qa-ffitest compiles util/ffitest.c
on the current platform then tests all data types.
Now ffi checks for nummber of arguments matching call pattern.
The opengl-demo-ffi.lsp now runs on both 32-bit and 64-bit newLISP
and libraries. On Windows glut32.dll is required. On Mac OSX everything
is installed by default.
ffi callback (ffi closure) working now on Mac OS X, Win32 and UBUNTU Linux
with standard installed libraries. Only for compiling/linking
libfffi-dev is necessary on UBUNTU linux.
The extended 'callback' API will not work on 64-bit Mac OSX newLISP,
but there is no problem to mix extended 'import' and simple 'callback' API
(see examples/opengl-demo.lsp)
Bit 11 for 0x400 in the last field of 'sys-info' is set for extended ffi
enabled versions requiring ffilib.
(not (zero? (& 0x400 (sys-info -1)))) => true for FFI support
Avoid passing on list or string references in primitives taking strings
or lists but creating new objects. This caused an error when doing
(inc (char str)) when str is protected. symbolCheck = NULL only neccessary
if not set to NULL by previous evaluateExprtession() to non-string/list.
Fixed on selected primitives.
qa-ffi and qa-libffi are now part of 'make testall'. They will not be
executed on versions not compiled for libffi based FFI.
10.3.9 development release December 21st 2011
'struct' function for extended FFI usage now working for 32 and 64 bit
(struct 'foo "char" "int" "short int")
Foo can now be used as a data type in the extended FFI API:
(import "thelib" "afunc" "foo" "foo") ; takes ans returns a struct foo
(unpack foo (afunc (pack foo 1 2 3))) => returns a list with 3 numbers
The additional syntax forms of 'pack' and 'unpack' take care for packing
and unpacking wirth the correct number of pad bytes to make align
structures on different Architectures.
See qa-special-tests/qa-libffi for an example.
Accept data lists in struct packing just like in traditional 'pack':
(struct 'pair "int" "int") => pair
(pack pair 1 2) => "\001\000\000\000\002\000\000\000"
(pack pair '(1 2)) => "\001\000\000\000\002\000\000\000"
Nested structure now can be packed:
(struct 'pair "char" "char") => pair
(struct 'comp "pair" "short int") => comp
(pack comp (pack pair 1 2) 3) => "\001\002\003\000"
Sub-structures are unpacked manually (may be changed):
(unpack comp (pack comp (pack pair 1 2) 3)) => ("\001\002" 3)
(set 'p (first (unpack comp (pack comp (pack pair 1 2) 3))))
(unpack pair p) => (1 2)
Because of memory management issues with cells in FFI symbols
extended ffi functions, structs and callbacks can only be defined
once. Subsequent definitions return nil and the existing definition
stays untouched.
Miscellanous fixes for 64-bit newLISP and ffilib usage.
Added custom ffi_type ffi_type_charpointer for displayable strings
now 'unpack' unpacks strings for "char*", not address numbers.
On Mac OSX 64-bits extended callback (ffi closure) does now work.
SHA256 crypto algorithm has been added to the module crypto.lsp.
Thanks to Marc Hildman for this contribution.
10.3.10 Development release Janaury 10th, 2012
Repeating ffi 'callback' with the same symbol will just return the old
address but not redefine the callback or return nil (as in 10.3.9).
examples/opengl-demo-ffi.lsp now also working with extended callback API
on 32-bit and 64-bit.
Huge speed improvement in 'read-line' with file handle parameter,
now as fast as STDIN. For file and pipe operations.
'struct's returned by the extended FFI will now be unpacked automatically.
Nested structures will be unpacked recursively too:
(struct 'pair "char" "char") -> pair
(struct 'comp "pair" "int") => comp
(pack comp (pack pair 1 2) 3) => "\001\002\000\000\003\000\000\000"
(unpack comp "\001\002\000\000\003\000\000\000") => ((1 2) 3)
Imported functions can now be default functors:
(define myprintf:myprintf (import "libc.dylib" "printf"))
(myprintf "%s %d" "hello world" 123)
All makefile_mingwdll* tweaked for MinGW gcc 4.6.2. But binaries are still
delivered compiled on gcc 4.4.0 and made on Windows XP SP2, run fine on
Windows 7. 10.3.6 to 10.3.9 had newlisp.dll compiled for cdecl now in
10.3.10 newlisp.dll calling conventations are back to stdcall.
10.4.0 stable release February 14th, 2012
UCT offset minutes as reported by the 'now' function now have reversed the
sign conform to ISO 8601. Positive for locations east of UCT and negative
for locations west of the UCT meridian (formerly GMT). Days of the year are
now reported from 1 - 365 (366 in leap years) instead of starting with
offset 0.
'read-char' w/o file handle reads from the current I/O device.
New version Guiserver 1.45 avoids error loops when midi system is unavailable.
In 'unify' the underscore symbol '_' matches any atom or list or variable.
Two new make files for the Raspberry PI development VM from:
http://russelldavis.org/2012/01/20/new-raspberry-pi-development-vm-v0-2/
These makefikes don't need the readline library, although it could be installed
as shown here:
http://russelldavis.org/2012/01/23/building-newlisp-for-the-raspberry-pi-using-the-development-vm/
newlisp.dll now also on Winsock version 2.2 (like the main executable since 10.2.10)
10.4.1 Development release April 3rd, 2012
The day-of-year value in 'date-list' now also starts with 1, like in 'now'.
Added CELL_IMPORT_FFI to various output functions (source, save etc.).
Added UTF-8 meta tag to newlispdoc HTML output.
Protect internally variable $x used in 'curry' and predefined 'module'.
When extended 'import' FFI is compiled, show 'libffi' in banner.
Added new function 'union' (composed of (unique (append ...))).
New functions 'odd?' and 'even?'
Fixed unix.lsp for new overwrite protection of imported symbols in ffilib version
An additional 'true' flag in (char str idx true) returns the byte value instead
of the UTF-8 character value at index idx in the string.
Handle probablilities less 0.5 in crit-z.
New 'prob-t', 'crit-t', 'prob-f', 'crit-f' for Student's t and F statistic.
'crit-chi2' redone for extreme values. All report small, significant
one-tailed probabilities for higher values of t, or F.
Adjustments in 'normal' for better fit.
Optional 'true' flag in 'file?' lets it return filename string.
Windows version should cut off trailing CR-LFs in string passed to 'command-event'.
10.4.2 stable maintenance release May 2nd, 2012
In extended ffi "char*" will now only accept strings not integer addresses to
string buffers. For passing integer addresses use "void*" - internally libffi
treats them as the same, but the new approach gives automatic type-checking
at the newLISP level without causing a segfault. Already for return values
"char*" always returns a newLISP string and "void*" an integer address.
A fix for 'pack' when packing structures made with 'struct' in 64-bit newLISP.
In 'import' for OSX/Linux/Unix allow libraries to be opened without importing
functions. This is necessary if an imported library refers to another one, e.g.:
(import "libgslcblas.dylib")
New module gsl.lsp with SVD, QR and Cholesky decompositions.
Added 'corr', 't-test' and 'stats' statistical functions.
New standard module gsl.lsp for SDV, QR and Cholesky decomp. and solver routines.
Updated plot.lsp with line and XY plot now a standard module.
10.4.3 stable maintenance release May 7th, 2012
(seek <file-handle>) after (read-line <file-handle>) was broken in 10.4.0 when
introducing faster file stream reading on 'read-line' and file closing could
leak memory.
10.4.4 Stable Maintenance Release September 15th, 2012
Eliminated getFloatFromCell() and replaced by getDirectFloat() in nl-math.c
Fixed error message for missing [/text] -tag when loading source from file.
read-file, write-file, append-file, delete-file when used with http:// URLs will
now return nil under error conditions instead of throwing an error. This is
consistent with error behavior on local files. When nil is returned, net-error
gives more error information. For remote server-side errors on URLs the server
HTTP error page is returned.
Check for UTF8 string validity in functions which are UTF8 sensitive.
An error message "invalid UTF8 string" is issued for invalid UTF8 strings.
Several - and continuing - manual updates, most of them also going into current
online version of manual.
guiserver.jar 1.47 fixes getting text from an empty gs:text-field.
Binary number format can be used with either 0b or 0B as prefix to up to 64
1's and 0's, e.g. 0b101010 for the number 42.
A 'true' flag as optional parameter in base64-enc will force the empty string
to be translated as "" instead of "====". Both cases translate correctly to
the empty string when fed into base64-dec.
Fixed a result stack overflow problem on callback's.
On OSX Mountain Lion 10.8.0 compiles also using clang instead of gcc.
10.4.5 Maintenance Release, November 21st, 2012
Doc changes.
Avoid overrun of invalid utf8 strings in utf8_wlen() in nl-utf8.c and
new error message "invalid UTF8 string". Used by several string functions
and indexing.
'process' on Windows now returns a real pid (process id) as on UNIX. Before
a Windows specific process handle was returned - thanks Johu -
Fix for loading .init.lsp on OpenBSD.
cgi.lsp now can handle mutipart form data in POST requests - thanks Unya -
Additions to postgres.lsp - thanks Unya -
Fixed a bug in 'ref' when multiple nested matching expressions.
Fixed a bug when using 'float' on list members (took the next element as
conversion default).
Added comments in newlisp.h and makefile_linuxLP64_utf8_ffi for CentOS 6.
Added makefile_linuxLP64_redhat_utf8_ffi and makefile_linux_redhat_utf8_ffi.
Work Centos and Fedora. Use ./configure to configure these makefiles for correct
libffi version. Thanks to Ivan Ribeiro for this contribution.
10.4.6 development version released on 2013-02-05
When using option 8 in xml-parse (translation of XML tags into newLISP symbols),
then the colon : in XML tags with namespace part, will be translated into a dot.
macro.lsp now works when defining default functors as macros.
A fix in cgi.lsp for receiving large POST data.
Fix for newlisp-edit.lsp for usage in OSX homebrew distribution.
In 'file?' the 'true' flag not only causes the filename to be returned but now
also implies that the filename is not a directory, else 'nil' is returned.
Crtl-D in Unix now will emit a line feed before exiting.
Added 'make android_dist' and 'make android_dist_utf8' for making
newlisp-ndk-x.x.x.tgz and newlisp-ndk-utf8-x.x.x.tgz package.
A fix in sort when the sorting function is generated at run-time.
On LINUX and BSD when compiled with GNU libreadline support a matching paren will
blink on the simple or multiple newLISP command line. For this the following line:
set blink-matching-paren on
should be put into Bash .inputrc
When making for Linux Android, 'share' and 'spawn' now work for data > 4072 bytes,
when a /data/tmp directory is created on the Android device.
This /data/tmp directory must also be present for CGI when running newLISP HTTP
server on Android.
Lower 4 bits of (sys-info -1) on Android is 11 but 'ostype' is "Linux".
JSON parser function (json-parse <string>) translates a JSON formatted string
into a S-expression. (json-error) returns error information of the form:
(<text str> <int-position>) when (json-parse <string>) returned 'nil'.
ECMA-262 compliant as defined at http://json.org
big/small -endian initilaization wasn't happening in LIBRARY compile flavor,
always assumed big-endian.
The module files: cgi.lsp, macro.lsp, plot.lsp and sqlite3.lsp have been updated.
Added error checking on net-select mode parameter.
Server mode now sets the REMOTE_ADDR environment variable to the IP-string of
the connecting client.
Last cell speed optimization for lists made with 'append', 'sequence', series
and 'rotate'.
10.4.7
Eliminate unused JSON error message.
Elminated usage of $0 in replace on lists (no regular expressions). The count
of replacements now is contained in the new $count system var, not $0. The usage
of $0 - $15 now is strictly for regular expressions. This also speeds up replace.
read-expr now uses $count instead of $0 for the number of characters processed.
Eliminated undocumented usage of $0 for found elements in find-all on lists.
Only $it is used. $0 only on find-all on strings with regular expressions.
The system variable $count is updated for all forms of find-all, ref-all and
set-ref-all.
Link feature now built in with comandline flag -x for all OS flavors:
newlisp -x <source-file> <executable-file>
The file util/link.lsp is not required anymore but has been included and
adapted to changes for the -x linkage. The file illustrates the internals
of the linkage process when using the -x option.
An additional true flag in the real-path function allows finding the executable
path of executables - similar to the "which" utility on UNIX. This is a by-
product of fixing the link.lsp feature for UNIX. The additional flag works
on all platforms. 'real-path' on Windows and BSD now also veryfies that path
and file are valid, as it already did on non-BSD Unix (OSX, Linux).
Enforce MAX_SYMBOL for tags in xml-parse and symbol creation using sym.
Security fixes for strncpy and strncat.
Windows CGI server mode was broken in development version 10.4.6 (isDir()).
Preparation for 64-bit Windows (in early summer).
10.4.8
Cleanup of the factor function.
Like date-parse, date-value will produce negative values for dates before 1970-1-1
til 1901-12-14.
The function 'flat' now can take an optioal depth parameter to limit flattening
a list up to certain level: (flat <list> [<level>])
(flat '(1 2 (3 4 (5 6)) (7 8 (9 10))) ) => (1 2 3 4 5 6 7 8 9 10)
(flat '(1 2 (3 4 (5 6)) (7 8 (9 10))) 1) => (1 2 3 4 (5 6) 7 8 (9 10))
(flat '(1 2 (3 4 (5 6)) (7 8 (9 10))) 2) => (1 2 3 4 5 6 7 8 9 10)
A fix for 'extend' when passing wrong type to unitialized symbol.
A fix in the parser to accept -.9 as -0.9 or +.9 as +0.9
=, +, -, *, /, %, ++, --, >, <, <=, >=, != operators and the functions 'abs',
'even?', 'odd?', 'length', 'number?' and 'zero?' are all working on big-integers
of unlimited size. 'float' and 'int' convert bigints into double floats and
64-bit integers and the function 'bigint' converts integers and floats to big
integers. See the section "Big integer, unlimited precision arithmetik" in
chapter 8. of the Users Manual for more information.
Extended commandline buffer to 1024 bytes.
The "debug" option in: (get-url "http://newlisp.org" "header debug") will now also
output the status header line of the server response in the console.
10.5.0 Stable Release May 21st, 2013
Further speed improvements on big integer multiplication and division/modulus.
Check for division by zero in big integer division/modulus.
Memory fix for ++, -- on big integers.
The OSX Intel version is now 64-bit by default.
10.5.1 development release Jun 4th, 2013
bigint will take mal-formed integers:
(bigint "hello") -> nil
(bigint "123hello") -> 123L
(bigint "+123hello") -> 123L
(bigint "-123hello") -> -123L
(bigint "123.456") -> 123L
but should not be used on string of scientific notation, it only converts the mantissa
(bigint "123.456e10" -> 123L
Fixed division when aligned or not aligned embedded bigint 0s (9 zeros).
Fixed more big integer division problems and added more tests to qa-bigint.
Compiler optimizations are now supressed in part of the big integer
division code to make it work on Linux. Does not affect performance.
10.5.2 development release June 26th, 2013
Fix for Java 7u21 in guisserver.jar, guiserver.lsp and newlisp-edit.
function gs:run-shell now takes separate command and args parameters.
New functions 'kmeans-train' and 'kmeans-query' for cluster analysis. The
Function 'kmeans-train' allows starting centroids to be either generated
randomly or be passed as an extra parameter. This allows clustering like
in Kmeans++ or other advanced schemes of pre-calculated start centroids.
When pre-calculated centroids are given, they are allowed to have less
columns, thus forcing kmeans clustering with less columns. This allows
to pre- or post-label the data set by including cluster-membership labels
in the last column.
(kmeans-train matrix-data int-k context [matrix-centroids])
return => list of inner SSQs for all iterations
matrix-data -> n rows by m columns (list or array)
int-k -> number of desired clusters
context -> new or existing context for results
matrix-centroids -> optional k * m starting centroids (list or array)
ctx:centroids -> k * m matrix of k centroids
ctx:deviations -> list of average intra cluster deviations = sqrt(ssq-cluster/n-cluster)
ctx:clusters -> list with k sublists each containing indices into data
ctx:labels -> list of n cluster labels, one for each data record
(kmeans-query list-data centroids)
return => list of k Eucledian distances from the k centroids
list-data -> data record to be classified
centroids -> result in namespace from previous kmeans-train or any other
list of data records to calculate Eucledian distances
'kmeans-query' can also be used for KNN (K Nearest Neighbour) analysis,
as it calculates the Eucledean distances for any matrix given in
the second argument, not only centroids, but e.g. the original
dataset. If the data-set is pre-labeled, then list-data has less
columns forcing to not include the label in analysis.
Fixed handling escaped " (quote) in JSON strings.
10.5.3 stable release July 10th, 2013
fixed escaping of back slashes in json-parse
file nl-xml.c renamed to nl-xml-json.c and makefiles changed accordingly
refactored nl-matrix.c/multiply() to avoid memory leak on wrong parameters
10.5.4 stable release October 1st, 2013
3.7 newlispdoc cleanup ";; *" regex
New FFI ffi.h include directory in makefile_linux* when installing libffi
Fix for last list element optimization in push, pop and pop-assoc when
popping and inserting last element
Accessing a deleted context will never hang but give an error message
Some changes in nl-filesys.c for AIX and new makefile for AIX ILP32
On Windows: a fix for correctly closing logfiles initiated by newlisp -l or
newlisp -L and for closing files created by the HTTP PUT operation.
Two sample 't-test' when variances are different (independent samples) with
new syntax:
(t-test <list-vector-A> <list-vector-B> <float-probabilty>)
When <float-probabilty> is specified, an internal F-test for variance
equality in data A and B is performed. If the probablity of F is
smaller than <float-probabilty>, then Welch's variant of the t-test for
independent samples is performed. Using 1.0 <float-probabilty>, Welch
can be forced even when variances are not significantly different.
One sample 't-test' using new syntax pattern:
(t-test <list-vector-data> <float-value>)
Gives the two-tailed probability that observed mean is differs from <float-value>
Instead of sdev for second list-vector the standard error for the observed mean
is reported.
Some cleanup and changes in scripts (makefiles) for binary installers
10.5.5 2013 November 20th, development release
Allow trailing , (comma) in JSON arrays. The new JSON ECMA-404 seems not
to allow it but the JavaScript standard ECMA-262 and many browsers do.
Added makefile_linux_openwrt for for TP-link TL-WR703N travel router
contributed by Dexter.
In arithmetik big integer operations + - * / % more than two operands
are allowed as in normal precision integer operations.
On Windows support UNIX conventions for formatting 64-bit integers.
I.e.: %lld %llu %llx %llX additionally to %I64d %I64u %I64x %I64X
Added ++, -- to qa-bigint. Fixed sign change on second operand of
bigint -- when second operand was negative.
Some cleanup in Cilk API when releasing resources.
The 'gcd' function now also works on big integers and > 2 operands.
On UBUNTU Linux decimal numbers can be formatted using a GNU extension
in libc, e.g: (format "%'d" 12345) => 12,345
The optional ' (single quote) after the % character causes thousands
to be separated with the appropiate character for the current locale.
Fixed a cell leak introduced in 10.5.5 when deleting contexts.
The default pretty-print float setting has been changed to "%1.15g".
'reset' now also cancels command line parameter processing.
A fix in 'round' when number is exacty 0.5.
'map', 'apply', 'stats', 'corr', 't-test' now also can take arrays
'bayes-query' with Fisher's Chi2 method calculated wrong probabilities
when training in more than two categories. When training in two
categories the result probabilities were swapped - reporting the
probability for the second category first. 'bayes-query' calculating
probabilities with the Chain Bayesian method - using the true flag -
was not affected.
Many documentation changes and corrections.
10.5.6 December 10th, 2013, development release
Since OSX 10.9 Maverick (format "%'d" 12345) => 12,345 will work too.
Will not work on any locale but works on en_US.UTF-8.
Fixed 'apply' for arrays introduced in 10.5.5 for a cell/memory leak.
When making hash trees using the predefined context 'Tree',
the default symbol in the new context is protected as is 'Tree:Tree'.
Default symbols in hash trees must be 'nil' in order for the hash
statement syntax for namespaces to work.
When copying symbols from a source context to a target contest using 'new'
or 'def-new', the 'protected?' property is copied too.
An empty list as index vector for a list or array yields the original
list or array as return value:
(set 'L '(1 2 (3 4)))
(L '()) => (1 2 (3 4))
(nth '() L) => (1 2 (3 4))
Many document changes, additions and corrections.
'int' can convert binarys numbers like (int "0b11111") => 31
This format is recognized by the code reader/loader since v.10.4.4.
Integers are accepted as hash keys. This allows creating sparse vectors:
(new Tree 'V)
(V 123 "hello")
(V 123) => "hello"
'reverse' can be used on arrays.
Anaphoric system variable $it is now set to the value of the conditional
expression in 'if'.
Speed improvements in evaluateExpression(). For this The -pendatic option
has been turned off in Linux to avoid ISO C90 mixed declaration warnings.
'length' on integers will return the number of digits, just like it already
does on bigint numbers, on floats returns the number of decimal digits before
the decimal separator.
10.5.7
Fixes for deprecated CYGWIN compile. See also makefile_cygwin for more info.
Clear potential error condition when doing 'import'.
In guiserver.jar: When adding columns with empty string headers, this will not
any more put the column number as header. This allows to add columns to
headerless tables, as possible when supplying empty string headers in the
initial gs:table statement.
Debugger will now always highlight the correct expression, not highlight
the first one if multiple instances exist.
Eliminated strncat() for BSD and better speed with memcpy() in most places.
Delay signal-behavior change in spawn after getting parameters. Makes better
error recovery.
In guiserver.jar: New table functions. Thanks to Ferry de Bruin.
gs:table-remove-row, gs:table-set-column-name and gs:table-set-row-count.
To avoid API naming confusions, the naming of old gs:table-set-row-number
is deprecated and should be called as gs:table-show-row-number.
The old naming will continue to work. Three new optional parameters for
'gs:scroll-pane' can specify colun header, row headers and a widget
for the top left corner of a table used in the scroll pane.
'find-all' should return an empty list as documented when nothing is found
on strings too.
Some renaming of functions and constants for better code readability and
some small refactoring in several files.
qa-bench has been redone with changes for Emscripten compiled newLISP.
Now calibrates for comparison with Mac OSX 9.1 on 2.3GHz Intel Core i5.
Fixed a crash bug when colon operator has missing or wrong-type args
on 64-bit compiles.
newLISP compiled to JavaSript with Emscripten
---------------------------------------------
Added makefile_emscripten_lib_utf8. For this
Must download and install the Emscripten-SDK from here:
https://github.com/kripken/emscripten/wiki/Emscripten-SDK
Tested on OSX 10.9 installing emsdk-portable.tar.gz v.1.7.8
The newlisp-js-lib.js is made using makefile_emscripten_lib_utf8.
The new function 'eval-string-js' takes a JavaSript string.
New 'display-html' can either replace the current page or display
a page in a new tab of the host browser. 'display-html' must be
defined in Emscripten appplication .html
Some functions (filter, index, clean, exists, forl-all) will not show
error messages under certain circumstanmces in the monitor, although
newLISP behaves correctly throwing the exception (setjmp/longjmp), they
just don't reach the Emscripten console (log). In this case, if the error
is not 'catch'ed newLISP exits without advising why. This problem goes away
when compiling with Emscriptem without any optimizations, but slows
everything down by a factor of 40 to 50. Normal performance is around
1.5 of native on Mac OSX when excluding all time/date related functions
and a few other outliers. Including outliers about 2.65.
See also here: https://github.com/kripken/emscripten/issues/810
(volatile declaration did not help)
All file and directory functions work (almost all did all the time),
but changes are lost after leaving the page or reloading the page.
Storage is 'session storage' only. No URLs are in allowed in file
functions as is on native compiled newLISP.
As editor, CodeMirror from codemirror.net is used and mode/newlisp.js
was created for syntax high-lighting.
10.5.8
'macro' is now a built-in primitive function working exactly as described
in the macro.lsp module, which is now obsolete. Macros cannot be redefined
using 'macro'. Macros can be nested. A symbol used as a macro can only be
used as a macro, even if changing the definition of it.
Another speed improvement for 'read-line' on file handles (the first speed
improvement happend in 10.3.10).
10.6.0
Eliminated emscripten-lib.c, gets handled by unix-lib.c.
A fix for 'file?' and 'directory?' predicates when applied to root
directories on Windows.
Updated examples/udp-server.lsp to nmake it work on Windows.
10.6.1 Development release September 16th, 2014
Added typedefs for CPPFunction and CPFuncition to compile on UBUNTU 14.04
with libreadline v.6.1.
Make qa-bigint and qa-bench work for UTF8 versions on all platform locales
by forcing the "C" "." locale at the beginning.
Report the result of the 'flt' function on all platforms as an unsigned
integer. Previously on 32bit newLISP versions a signed integer was
reported and an unsigned integer on 64bit versions.
'rotate' on (copy str) corrupted memory when using optimized copyCell().
Delay cell deletion for indexed strings if not referenced by a symbol;
already happens for lists.
In 'regex' in utf8 versions and when specifying the PCRE_UTF8 parameter
- 2048 or "u" - give offset and length in number utf8 characters:
(regex "Ω" "ΨΩ") => ("Ω" 2 2)
(regex "Ω" "ΨΩ" "u") => ("Ω" 1 1)
(regex "Ω" "ΨΩ" 2048) => ("Ω" 1 1)
A second call pattern for 'copy'
(copy <s-expr>) ; <- original syntax
(copy <int-addr> true) ; <- new syntax
The new syntax marked by the true 'flag' takes a memory address of a cell
and copies it. The following expressions are equivalent:
(copy cell) <=> (copy (first (dump cell)) true)
'get-string' now can take one or two additional optional parameters:
(get-string <address>) ; gets an zero terminated ASCII or UTF-8 string
(get-string <address> <bytes>) ; gets a buffer of <bytes> of binary data
(get-string <address> <max-bytes> <str-limit) ; reads to <str-limit> or max
The second pattern would work for UTF-32/UCS-4 this way:
(get-string <address> <max-bytes> "\000\000\000\000")
Any other string in <str-limit> can be specified to stop reading
If comparing with \000\000 or \000\000\000\000 comparison is aligned
to 2 or 4 byte boundary for specifying UCS-2 or UCS-4 string limits.
Highest bit of crc32 does should not get sign extended in 32-bit newLISP.
New function (collect <exp>) collects in a list while <exp> evaluates to
not nil:
(let (x 0) (collect (if (<= (inc x) 5) x))) => (1 2 3 4 5)
the int-option parameter in functions using regular expressiona can now be
a string for PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, PCRE_EXTENDED
PCRE_UTF8, PRECOMPILED using the letters i,m,s,x,u,p.
example: (find "x.z" "abcX\nZ" "is") => 3
in functions: directory, ends-with, find, find-all, parse, regex, regex-comp,
replace, search and starts-with
The protected? function did not recognize macro symbols as protected.
Cleanup for 64-bit time_t on 32-bit Windows. Thanks Kosh!
The 'macro?' function also works on 'macro' symbols.
A wrong UDP option in net-connect and net-listen now throws an error.
Distribution packages for Linux are now with a newLISP executable compiled
for 64-bit.
In Emscripten v.1.22.0 compiled newLISP exception handling now works.
10.6.2 January 20, 2015
When parsing binary, hex, decimal, float and integer numbers, now up to
1000 digits are parsed when present. The rest will be read as new token(s).
Note that IEEE 754 64-bit doubles distinguish only up to 16 significant
digits. For big integers the 1000 limitation exists only when parseing
source. There is no limit when a result of big integers math exceeds 1000
digits.
Added makefile_bsdLP64_utf8_ffi
varPrintf() now always avoids printing format strings without args.
Improve libffi detection with newlisp-x.x.x/configure on RedHat Linux.
On BSDs if /usr/local/include/ffi.h is present the libffi versions gets
compiled when using: ./configure, which is used by default when just
issuing: make
Fixed multi-line shell mode on Windows when comments are present.
New definition of stuffFloat() to avoid compiler error in p_getFloat()
which needed inlining old stuffFloat(). Test using:
(get-float (address (get-long (address 17.4)))) => 17.4
Optional int-max-count parameter for the 'collect' primitive.
Cacheing crc-table in crc32 function for speedup in repeated use.
The default print floating point format changed from "%1.15g" to "%1.16g".
(can always be user changed using pretty-print function)
A third syntax of 'reset' allows resetting the maximum cell count without
restarting the system. The minimum is 4095. Trying to allocate more cells
than the minimum allocated makes the program exit.
When using 'json-parse', null now gets translated to a symbol 'null' in
newLISP not 'nil' as before. So all three JSON values true, false and null
keep their appearance in newLISP symbolic expressions.
Many small additions and changes to newlisp_manual.html.
10.6.3 July 8th, 2015 Development release
Starting with this version only use the TDM-GCC-64 toolchain, it
uses mingw32 and can compile for both, 32-bit and 64-bit.
On some Windows versions negative time value in 'date-list' for dates
before 1970-1-1 are not handled by gmtime() and could crash newLISP.
Now an error 44 is thrown when gmtime() cannot handle negative values.
Fixed 'det' and 'mat' for Ubuntu Linux when using wrong dimensions.
Tested on OSX, OpenBSD, FreeBSD Ubuntu Linux, Windows.
Changes in several files for compiling a 64-bit version for Windows
using mingw64. Thanks to Shigeru Kobayashi for doing this work.
Filenames win32xxx.c change to win-xxx.c.
The 'dolist' function now also works on arrays.
The 'net-eval' functions now return the result of the last expression
in the string argument, not the first.
(net-eval host port "(+ 3 4) (* 3 4)" => 12 ; previously 7
In previous versions, although all expressions in 'net-eval' would be
evaluated, the result of the first was returned. The possibility
of multiple expressions in a string was not documented. The new
behaviour is more in line with the behaviour of 'eval-string' and
'load'.
Fixed a bug on Windows when APACHE was starting newlisp and no
NEWLISPDIR wnd PROGRAMFILES environment variables were defined.
New makefiles for Windows:
makefile_mingw64 makefile_mingw64_ffi
makefile_mingw64_utf8 makefile_mingw64_utf8_ffi
makefile_mingw64dll makefile_mingw64dll_ffi
makefile_mingw64dll_utf8 makefile_mingw64dll_utf8_ffi
are working. Tested using tdm gcc 64 (MinGW based).
The configure utility now uses the mingw64 makefiles if LLP64 is present.
The configure-alt utility still only compiles for 32-bit.
Both, 32-bit and 64-bit newLISP on Windows, now have ostype "Windows".
In modules canvas.lsp and gsl.lsp ostype has been changed to "Windows"
from "Win32". Same change in many qa-* files and web applications.
C type cleanup for string size_t length in some C-functions.
Server mode -http did not reject net-eval requests.
'net-eval' connection timeout changed to 15 secs from 60 secs.
Processing timeout still set by user in 'net-eval' parameter.
Added HTTP_AUTHORIZATION to environment variables in HTTP server.
Additional syntax for 'date-value' -> (date-value list-date-time).
Additional syntax (date-list) now same as (date-list (date-value)).
The 'trim' function without trim-char parameters will trim all
white-space characters, not only spaces.
Fixed 'expand' bug when evaluating binding lists.
'dump' now returns the number of cells dumped not 'true'
New 'trace' syntax: (trace device-no) prints an evaluation trace to
device-no. Example:
(trace (open "trace.txt" "w")) ; open trace file (or "a")
... ; one or more expressions to evaluate
(trace nil) ; close trace file
Stack trace in error message changed from function name to full
expression.
tmp directory is now defined on newLISP startup. For UNIX it is /tmp
for Windows it is taken from TMP environment variable or assumed /tmp.
This directory is used by the 'share' functions and the built-in http
server.
When char* in libffi returns 0 (NULL) then an error message will be
thrown: "cannot convert NULL to string".
A new newLISP library call (newlispLibConsole 1) forces console output
for stdout instead of writing it to the return string of newlispEvalStr.
The same also enables console input on stdin.
The 'json-parse' function now handles 64-bit number also in 32-bit versions
of newLISP.
Fixed shape sign error in canvas.lsp for bezier curves in shapes.
10.6.4 September 24th, 2015 Development Release
Now can retrieve 0-length document with 'get-url'.
A fix for 'share' on Linux (bug introduced in development v.10.6.3)
In 'get/put/post-url' the new string option "raw" inhibits 'Location'
redirection. "raw" can also be combined with the "list" and "debug" options.
When in "list" mode now the server status code is added as a third list
member.
Fixed a error date-value introduced in 10.6.3.
Fixed potential error in my_vasprintf() only used on Windows, OS2, TRU64,
Solaris and AIX.
Avoid calling varargs function sendf() with empty argptr nl-web.c.
Avoid allocating too much stack space in getPutPostDeleteUrl().
Response string from 'get/put/post-url' was not zero-terminated for
HTTP error returns.
When a HTTP server returns an error code and also returns content,
the string "ERR: " with the HTTP server response line gets prepended when
not in list mode. This is necessary for compatibility with previous
versions, as delete/get/put/post -url always return a string and errors
are marked by a beginning "ERR: " of the string.
In list mode the second string in the list contains only the returned content.
The third list member is the server HTTP response line. The fourth list
member contains the status-code, which is 0 for an invalid HTTP response.
date-value did not evaluate month, day parameters.
Last element list optimization now always retained when using pop on the list.
PCRE options PCRE_NOTBOL, PCRE_NOTEOL and PCRE_NOTEMPTY did not work.
Expansion 'macro' definitions can be redefined with 'contanst' not 'define'
as described in the manual.
Installation prefix changed from /usr to /usr/local for OSX and other Unix.
The 'save' function now saves symbols with strings longer 2047 chars
appending multiple partial lines of "," delimited strings of up to 72
characters. This allows to \ escape non-displayable characters, which
[text],[/text] delimited text not allows.
New version 1.7 canvas.lsp fixes ellipse, petal, pie, polygon, shape:
now first fill() then stroke() as in postscript.lsp.
Loading an empty file should return nil.
On Mac OS X guiserver expects newlisp in /usr/local/bin/newlisp on all other
OS it is only is expected in the executable path, as in previous versions.
10.6.5
In the crypto.lsp module "cdecl" must be used when importing on Windows.
(since v.10.6.3 a new compiler setup is used)
A second PRNG with variable initial N for seed initialization
via (seed S true N) and inquiry of current seed state via (seed).
This PRNG is built-in with same results across all platforms and
compilers. The current PRNG will stay as it offers a bigger set of
random numbers on Unix platforms. This new PRNG is necessary for doing
computer simulations and AI art, which is reproducable across
platforms and where random number sequences can be broken up in
repeatable layers using the (seed) instruction to save state.
When using the default libc based PRNG (seed) now returns the last
seed set by the programmer. On the new PRNG (seed) returns the last
seed state. - Not yet documented, may replace old PRNG in the future.
A (ssq vector) sum of squares function has been added. The vector can
be either a list or array vector.
guiserver.jar version 1.65 now correctly forces updates of a gs:canvas
in a gs:scroll-pane.
When a deleted symbol was prefix in a dynamic symbol, memory got corrupted.
The dynamic symbol reference is now replaced with nil like other symbol
references.
A illegal symbol when trying to create a context could crash the system,
when referenced again after the error message.
10.7.0 version 10.6.5 released as stable release January 2016.
