The Emacs jobset is defined in the Emacs source tree, file

'test/infra'. They could be adapted for every Emacs branch, see

A jobset on Gitlab is called pipeline. Emacs pipelines run through

(create an Emacs instance by 'make bootstrap' with different
configuration parameters) as well as 'normal', 'slow', 'platforms' and
configuration parameters) as well as 'normal', 'platforms' and
'native-comp' (run respective test jobs based on the produced images).
The jobs for stage 'normal' are contained in the file
'test/infra/test-jobs.yml'. This file is generated by calling 'make
-C test generate-test-jobs' in the Emacs source tree, and the
resulting file shall be pushed to the Emacs git repository afterwards.
Every job runs in a Debian docker container. It uses the local clone
of the Emacs git repository to perform a bootstrap and test of Emacs.
This could happen for several jobs with changed configuration, compile

@end example
Instead of using @code{kbd}, you can use a Lisp string or vector to
specify the key sequence. Using a string is simpler, but only works
for @acronym{ASCII} characters and Meta-modified @acronym{ASCII}
characters. For example, here's how to bind @kbd{C-x M-l} to
@code{make-symbolic-link} (@pxref{Copying and Naming}):
@example
(global-set-key "\C-x\M-l" 'make-symbolic-link)
@end example
To bind a key sequence including @key{TAB}, @key{RET}, @key{ESC}, or
@key{DEL}, the string should contain the Emacs Lisp escape sequence
@samp{\t}, @samp{\r}, @samp{\e}, or @samp{\d} respectively. Here is
an example which binds @kbd{C-x @key{TAB}} to @code{indent-rigidly}
(@pxref{Indentation}):

@end example
When the key sequence includes function keys or mouse button events,
or non-@acronym{ASCII} characters such as @code{C-=} or @code{H-a},
you can use a vector to specify the key sequence. Each element in the
vector stands for an input event; the elements are separated by spaces
and surrounded by a pair of square brackets. If a vector element is a
character, write it as a Lisp character constant: @samp{?} followed by
the character as it would appear in a string. Function keys are
represented by symbols (@pxref{Function Keys}); simply write the
symbol's name, with no other delimiters or punctuation. Here are some
examples:
@example
(global-set-key [?\C-=] 'make-symbolic-link)
(global-set-key [?\M-\C-=] 'make-symbolic-link)
(global-set-key [?\H-a] 'make-symbolic-link)
(global-set-key [f7] 'make-symbolic-link)
(global-set-key [C-mouse-1] 'make-symbolic-link)

@appendix Emacs and Haiku
@cindex Haiku
Haiku is a Unix-like operating system that originated as a
re-implementation of the operating system BeOS.
This section describes the peculiarities of using Emacs built with
the Application Kit, the windowing system native to Haiku. The
oddities described here do not apply to using Emacs on Haiku built
without windowing support, or built with X11.

@node Haiku Basics
@section Installation and usage peculiarities under Haiku
@cindex haiku application
@cindex haiku installation
Emacs installs two separate executables under Haiku; it is up to the
user to decide which one suits him best: A regular executable, with
the lowercase name @code{emacs}, and a binary containing
Haiku-specific application metadata, with the name @code{Emacs}.
@cindex launching Emacs from the tracker
@cindex tty Emacs in haiku
If you are launching Emacs from the Tracker, or want to make the
Tracker open files using Emacs, you should use the binary named
@code{Emacs}; if you are going to use Emacs in the terminal, or wish
to launch separate instances of Emacs, or do not care for the
aforementioned system integration features, use the binary named
@code{emacs} instead.
@cindex modifier keys and system keymap (Haiku)
@cindex haiku keymap
On Haiku, unusual modifier keys such as the Hyper key are
unsupported. By default, the super key corresponds with the option
key defined by the operating system, the meta key with the command
key, the control key with the system control key, and the shift key
with the system shift key. On a standard PC keyboard, Haiku should
map these keys to positions familiar to those using a GNU system, but
this may require some adjustment to your system's configuration to
work.
It is impossible to type accented characters using the system super
key map.
You can customize the correspondence between modifier keys known to
the system, and those known to Emacs. The variables that allow for
that are described below.
@cindex modifier key customization (Haiku)
@table @code
@vindex haiku-meta-keysym
@item haiku-meta-keysym
The system modifier key that will be treated as the Meta key by Emacs.
It defaults to @code{command}.
@vindex haiku-control-keysym
@item haiku-control-keysym
The system modifier key that will be treated as the Control key by
Emacs. It defaults to @code{control}.
@vindex haiku-super-keysym
@item haiku-super-keysym
The system modifier key that will be treated as the Super key by
Emacs. It defaults to @code{option}.
@vindex haiku-shift-keysym
@item haiku-shift-keysym
The system modifier key that will be treated as the Shift key by
Emacs. It defaults to @code{shift}.
@end table
The value of each variable can be one of the symbols @code{command},
@code{control}, @code{option}, @code{shift}, or @code{nil}.
@code{nil} or any other value will cause the default value to be used
instead.
@cindex tooltips (haiku)
@cindex haiku tooltips
@vindex haiku-use-system-tooltips
On Haiku, Emacs defaults to using the system tooltip mechanism.
This usually leads to more responsive tooltips, but the tooltips will
not be able to display text properties or faces. If you need those
features, customize the variable @code{haiku-use-system-tooltips} to
the nil value, and Emacs will use its own implementation of tooltips.
Both system tooltips and Emacs's own tooltips cannot display above
the menu bar, so help text in the menu bar will display in the echo
area instead.
@subsection What to do when Emacs crashes
@cindex crashes, Haiku
@cindex haiku debugger
@vindex haiku-debug-on-fatal-error
If the variable @code{haiku-debug-on-fatal-error} is non-nil, Emacs
will launch the system debugger when a fatal signal is received. It
defaults to @code{t}. If GDB cannot be used on your system, please
attach the report generated by the system debugger when reporting a
bug.
@node Haiku Fonts
@section Font and font backend selection on Haiku
@cindex font backend selection (Haiku)
Emacs, when built with Haiku windowing support, can be built with
several different font backends. You can specify font backends by
specifying @kbd{-xrm Emacs.fontBackend:BACKEND} on the command line
used to invoke Emacs, where @kbd{BACKEND} is one of the backends
specified below, or on a per-frame basis by changing the
@code{font-backend} frame parameter.
Two of these backends, @code{ftcr} and @code{ftcrhb} are identical
to their counterparts on the X Window System. There is also a
Haiku-specific backend named @code{haiku}, that uses the App Server to
draw fonts, but does not at present support display of color font and
emoji.

understand a number of different syntaxes for the keys.
The functions below signal an error if @var{keymap} is not a keymap,
or if @var{key} is not a valid key.
@table @asis
@item A vector containing a single string.
This is the preferred way to represent a key sequence. Here's a
couple of examples:
@var{key} is a string representing a single key or a series of key
strokes. Key strokes are separated by a single space character.
@example
["C-c M-f"]
["S-<home>"]
@end example
Each key stroke is either a single character, or the name of an
event, surrounded by angle brackets. In addition, any key stroke
may be preceded by one or more modifier keys. Finally, a limited
number of characters have a special shorthand syntax. Here's some
example key sequences:
The syntax is the same as the one used by Emacs when displaying key
bindings, for instance in @samp{*Help*} buffers and help texts.
@table @kbd
@item f
The key @kbd{f}.
If the syntax isn't valid, an error will be raised when running
@code{define-key}, or when byte-compiling code that has these calls.
@item S o m
A three key sequence of the keys @kbd{S}, @kbd{o} and @kbd{m}.
@item A vector containing lists of keys.
You can use a list containing modifier names plus one base event (a
character or function key name). For example, @code{[(control ?a)
(meta b)]} is equivalent to @kbd{C-a M-b} and @code{[(hyper control
left)]} is equivalent to @kbd{C-H-left}.
@item C-c o
A two key sequence of the keys @kbd{c} with the control modifier and
then the key @kbd{o}
@item A string with control and meta characters.
Internally, key sequences are often represented as strings using the
special escape sequences for control and meta characters
(@pxref{String Type}), but this representation can also be used by
users when rebinding keys. A string like @code{"\M-x"} is read as
containing a single @kbd{M-x}, @code{"\C-f"} is read as containing a
single @kbd{C-f}, and @code{"\M-\C-x"} and @code{"\C-\M-x"} are both
read as containing a single @kbd{C-M-x}.
@item H-<left>
The key named @kbd{left} with the hyper modifier.
@item a vector of characters.
This is the other internal representation of key sequences, and
supports a fuller range of modifiers than the string representation.
One example is @samp{[?\C-\H-x home]}, which represents the @kbd{C-H-x
home} key sequence. @xref{Character Type}.
@item M-RET
The @kbd{return} key with a meta modifier.
@item C-M-<space>
The @kbd{space} key with both the control and meta modifiers.
@end table
The functions below signal an error if @var{keymap} is not a keymap,
or if @var{key} is not a string or vector representing a key sequence.
You can use event types (symbols) as shorthand for events that are
lists. The @code{kbd} function (@pxref{Key Sequences}) is a
convenient way to specify the key sequence.
The only keys that have a special shorthand syntax are @kbd{NUL},
@kbd{RET}, @kbd{TAB}, @kbd{LFD}, @kbd{ESC}, @kbd{SPC} and @kbd{DEL}.

@node Low-Level Key Binding
@section Low-Level Key Binding
@cindex low-level key bindings
Historically, Emacs has supported a number of different syntaxes for
defining keys. The documented way to bind a key today is to use the
syntax supported by @code{key-valid-p}, which is what all the
functions like @code{keymap-set} and @code{keymap-lookup} supports.
This section documents the old-style syntax and interface functions;
they should not be used in new code.
@cindex meta character key constants
@cindex control character key constants
@code{define-key} (and other low-level functions that are used to
rebind keys) understand a number of different syntaxes for the keys.
@table @asis
@item A vector containing lists of keys.
You can use a list containing modifier names plus one base event (a
character or function key name). For example, @code{[(control ?a)
(meta b)]} is equivalent to @kbd{C-a M-b} and @code{[(hyper control
left)]} is equivalent to @kbd{C-H-left}.
@item A string of characters with modifiers
Internally, key sequences are often represented as strings using the
special escape sequences for shift, control and meta modifiers
(@pxref{String Type}), but this representation can also be used by
users when rebinding keys. A string like @code{"\M-x"} is read as
containing a single @kbd{M-x}, @code{"\C-f"} is read as containing a
single @kbd{C-f}, and @code{"\M-\C-x"} and @code{"\C-\M-x"} are both
read as containing a single @kbd{C-M-x}.
@item A vector of characters and key symbols
This is the other internal representation of key sequences. It
supports a fuller range of modifiers than the string representation,
and also support function keys. An example is @w{@samp{[?\C-\H-x
home]}}, which represents the @w{@kbd{C-H-x @key{home}}} key sequence.

@defun define-key keymap key binding &optional remove
This function is like @code{keymap-set} (@pxref{Changing Key

In addition, this function also has a @var{remove} argument. If it is
non-@code{nil}, the definition will be removed. This is almost the
same as setting the definition to @code{nil}, but makes a difference
if the @var{keymap} has a parent, and @var{key} is shadowing the same
binding in the parent. With @var{remove}, subsequent lookups will
return the binding in the parent, and with a nil @var{def}, the
lookups will return @code{nil}.
@end defun

equivalent modern function to use instead in new code.

@var{olddef} is replaced with @var{newdef} wherever it appears. The
function returns @code{nil}. Use @code{keymap-substitute} instead.
@end defun
@defun define-key-after map key binding &optional after
Define a binding in @var{map} for @var{key}, with value @var{binding},
just like @code{define-key}, but position the binding in @var{map} after
the binding for the event @var{after}. The argument @var{key} should be
of length one---a vector or string with just one element. But
@var{after} should be a single event type---a symbol or a character, not
a sequence. The new binding goes after the binding for @var{after}. If
@var{after} is @code{t} or is omitted, then the new binding goes last, at
the end of the keymap. However, new bindings are added before any
inherited keymap. Use @code{keymap-set-after} instead of this function.
@end defun

@defun key-binding key &optional accept-defaults no-remap position
This function returns the binding for @var{key} according to the

(@pxref{Functions for Key Lookup}). If @var{no-remap} is
non-@code{nil}, @code{key-binding} ignores command remappings
(@pxref{Remapping Commands}) and returns the binding directly
specified for @var{key}. The optional argument @var{position} should
be either a buffer position or an event position like the value of
@code{event-start}; it tells the function to consult the maps
determined based on that @var{position}.
Emacs signals an error if @var{key} is not a string or a vector.
Use @code{keymap-lookup} instead of this function.
@end defun
@defun lookup-key keymap key &optional accept-defaults
This function returns the definition of @var{key} in @var{keymap}. If
the string or vector @var{key} is not a valid key sequence according
to the prefix keys specified in @var{keymap}, it must be too long and
have extra events at the end that do not fit into a single key
sequence. Then the value is a number, the number of events at the
front of @var{key} that compose a complete key.
If @var{accept-defaults} is non-@code{nil}, then @code{lookup-key}
considers default bindings as well as bindings for the specific events
in @var{key}. Otherwise, @code{lookup-key} reports only bindings for
the specific sequence @var{key}, ignoring default bindings except when
you explicitly ask about them.

** Haiku
On 32-bit Haiku it is required that the newer GCC 8 be used, instead
of the legacy GCC 2 used by default. This can be achieved by
invoking configure inside a shell launched by the 'setarch' program
invoked as 'setarch x86'.
When building with packages discovered through pkg-config, such as
libpng, on a GCC 2/GCC 8 hybrid system, simply evaluating 'setarch
x86' is insufficient to ensure that all required libraries are found
at their correct locations. To avoid this problem, set the
environment variable 'PKG_CONFIG_PATH' to the GCC 8 pkg-config
directory at '/system/develop/lib/x86/pkgconfig/' before configuring
Emacs.
If GCC complains about not being able to resolve symbols such as
"BHandler::LockLooper", you are almost certainly experiencing this
problem.
Haiku running on non-x86 systems has not been tested. It is
anticipated that Haiku running on big-endian systems will experience
problems when Emacs is built with Haiku windowing support, but there
doesn't seem to be any reliable way to get Haiku running on a
big-endian system at present.
The earliest release of Haiku that will successfully compile Emacs
is R1/Beta2. For windowing support, R1/Beta3 or later is required.

The configuration process should automatically detect and build for

can be enabled by configuring Emacs with the option '--with-be-app',
which will require the Haiku Application Kit development headers and a
C++ compiler to be present on your system. If Emacs is not built with
the option '--with-be-app', the resulting Emacs will only run in

*** Cairo drawing support has been enabled for Haiku builds.
To enable Cairo support, ensure that the Cairo and FreeType
development files are present on your system, and configure Emacs with
'--with-be-cairo'.

*** Double buffering is now enabled on the Haiku operating system.
Unlike X, there is no compile-time option to enable or disable
double-buffering. If you wish to disable double-buffering, change the
frame parameter `inhibit-double-buffering' instead.
** Emacs now installs the ".pdmp" file using a unique fingerprint in the name.
The file is typically installed using a file name akin to
"...dir/libexec/emacs/29.1/x86_64-pc-linux-gnu/emacs-<fingerprint>.pdmp".
If a constant file name is required, the file can be renamed to
"emacs.pdmp", and Emacs will find it during startup anyway.
** Emacs now supports use of XInput 2 for input events.
If your X server has support and you have the XInput 2 development headers
installed, you can configure Emacs with the option '--with-xinput2' to enable
this support.
The named feature `xinput2' can be used to test for the presence of
XInput 2 support from Lisp programs.
