<h1>newLISP<font size=-1>®</font> v.10.7.0 Stable Release
|
|
<font color="red" size="-1">2016-01-21</font></h1>
|
|
|
|
<p>This stable release adds new functionality to existing functions,
|
|
adds one new function and fixes bugs.</p>
|
|
|
|
|
|
<h3>Additions and changes</h3>
|
|
|
|
<ul>
|
|
<li>The installation location prefix for OS X, Linux and other Unix like
|
|
platforms has been changed from <tt>/usr</tt> to <tt>/usr/local</tt> for
|
|
installation in the <tt>/usr/local/</tt> directory. See also the file
|
|
<tt>makefile-original-install</tt> in the main source directory.</li>
|
|
|
|
<li>On Mac OS X, when starting <tt>guiserver.jar</tt> first, when it is not
|
|
loaded by another newLISP program, <tt>guiserver.jar</tt> expects the newlisp
|
|
executable in <tt>/usr/local/bin/newlisp</tt>. On other UNIX the newlisp
|
|
executable must be in the executable path of the operating system.</li>
|
|
|
|
<li>On MS Windows, newLISP can now be compiled as a 64-bit executable.
|
|
Thanks to <i>Shigeru Kobayashi</i> for doing most of this work.</li>
|
|
|
|
<li><tt>dolist</tt> now also accepts arrays.</li>
|
|
|
|
<li>The <tt>net-eval</tt> function now returns the evaluation
|
|
of the last expression passed, not the first. The possibility of
|
|
passing more than one expression in <tt>net-eval</tt> is not
|
|
documented.</li>
|
|
|
|
<li>The system variable <tt>ostype</tt> on MS Windows now reports
|
|
the string <tt>"Windows"</tt>. In previous version 1.62 <tt>"Win32"</tt>
|
|
was reported.</li>
|
|
|
|
<li>The <tt>net-eval</tt> connection timeout has changed to 15 seconds
|
|
from 60 secconds. The processing timeout while connected can still be set
|
|
by the user in a <tt>net-eval</tt> parameter.</li>
|
|
|
|
<li>The environment variable <tt>HTTP_AUTHORIZATION</tt> has been
|
|
added to the variables handled in HTTP server mode.</li>
|
|
|
|
<li>In <tt>date-value</tt> the date and time numbers can now be
|
|
given in one list instead of separate number parameters using and
|
|
additional syntax.</li>
|
|
|
|
<li>The <tt>date-list</tt> function, when given without a parameter,
|
|
now returns the date list for the current UTC date and time value.</li>
|
|
|
|
<li>The <tt>trim</tt> function without trim character parameters will
|
|
now trim all white-space characters, not only spaces.</li>
|
|
|
|
<li><tt>dump</tt> now returns the number of cells dumped. Previously
|
|
<tt>true</tt> was returned.</li>
|
|
|
|
<li>A new <tt>trace</tt> syntax <tt>(trace <em>int-device</em>)</tt> writes
|
|
all expression entries and exit results to the device given.
|
|
<em>int-device</em> can be the handle of an <tt>open</tt>'ed file or
|
|
<tt>1</tt> for <em>stdout</em>.</li>
|
|
|
|
<li>The stack trace in error messages now prints the entire expression
|
|
passed for evaluation, not only the function name.</li>
|
|
|
|
<li>The <tt>tmp</tt> directory is now defined during newLISP startup.
|
|
For UNIX this is <tt>/tmp</tt>, for Windows it is taken from the
|
|
<tt>TMP</tt> environment variable or assumed as <tt>/tmp</tt> when <tt>TMP</tt>
|
|
is not defined. The directory is used by the built-in function <tt>share</tt>
|
|
and the built-in HTTPD server.</li>
|
|
|
|
<li>A new newLISP library call <tt>(newlispLibConsole 1)</tt> forces console
|
|
output to <em>stdout</em> instead of writing to the return string of
|
|
<tt>newlispEvalStr</tt>. The same call also enables console input via
|
|
<em>stdin</em>.</li>
|
|
|
|
<li>In <tt>get/put/post-url</tt> the new string option <tt>"raw"</tt> inhibits
|
|
'Location' redirection. <tt>"raw"</tt> parameter can also be combined with the
|
|
<tt>"list"</tt> and <tt>"debug"</tt> options, e.g. <tt>"raw debug"</tt>.</li>
|
|
|
|
<li>In <tt>get/put/post-url</tt> list mode the second string in the returned 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.</li>
|
|
|
|
<li>The <tt>save</tt> function now saves symbols with strings longer than 2027
|
|
characters appending multiple partial lines delimited by quotes <tt>"..."</tt>.
|
|
This way lines can contain escape characters which are not allowed when using
|
|
<tt>[text]...[/text]</tt> tags as delimiters.</li>
|
|
|
|
<li>When using a new second <tt>seed</tt> syntax, all randomizing functions are
|
|
based on a random generator independent of platforms and compilers used to built
|
|
newLISP. When seeding using the second syntax all random functions called subsequenly
|
|
like <tt>amb</tt>, <tt>normal</tt>, <tt>rand</tt>, <tt>random</tt> and <tt>randomize</tt>
|
|
are based on this platform independent random generator. After initializing with
|
|
the new <tt>seed</tt> syntax a subsequent call to <tt>seed</tt> without parameters
|
|
returns the current seed state of the random generator, which can be used at a later
|
|
time to seed the generator for the same state in a sequence.</li>
|
|
|
|
<li>A new <tt>ssq</tt> function returns the Sum of SQquares (SSQ) for a list or array
|
|
vector.</li>
|
|
|
|
|
|
</ul>
|
|
|
|
<h3>Bug fixes</h3>
|
|
|
|
<ul>
|
|
<li><tt>date-list</tt> crashed for negative values on some MS Windows versions.</li>
|
|
|
|
<li>The <tt>det</tt> and <tt>mat</tt> functions now give an
|
|
error message when passed the wrong dimensions.</li>
|
|
|
|
<li>HTTP server mode now works correctly with Apache server, when the environment
|
|
variables NEWLISPDIR and PROGRAMFILES are not defined. Default file paths
|
|
are then assumed for these variables.</li>
|
|
|
|
<li>HTTP only server mode with command-line switch <tt>-http</tt> did not
|
|
reject <tt>net-eval</tt> requests.</li>
|
|
|
|
<li><tt>expand</tt> could crash when evaluating binding lists.</li>
|
|
|
|
<li>The <tt>json-parse</tt> function now handles 64-bit numbers also in 32-bit
|
|
versions of newLISP.</li>
|
|
|
|
<li>Response string from <tt>get- put- post-url</tt> was not zero-terminated for
|
|
HTTP error returns.</li>
|
|
|
|
<li><tt>date-value</tt> did not evaluate month, day parameters.</li>
|
|
|
|
<li>PCRE options PCRE_NOTBOL, PCRE_NOTEOL and PCRE_NOTEMPTY did not work.</li>
|
|
|
|
<li>Loading an empty file now returns <tt>nil</tt> instead of throwing an
|
|
error.</li>
|
|
|
|
<li>guiserver.jar version 1.65 now correctly forces updates of a <tt>gs:canvas</tt>
|
|
in a <tt>gs:scroll-pane</tt>.
|
|
|
|
</ul>
