xkbcomp - compile XKB keyboard description
xkbcomp [option] source [ destination ]
The xkbcomp keymap compiler converts a description of an XKB keymap
into one of several output formats. The most common use for xkbcomp
is to create a compiled keymap file (.xkm extension) which can be read
directly by XKB-capable X servers or utilities. The keymap compiler
can also produce C header files or XKB source files. The C header
files produced by xkbcomp can be included by X servers or utilities
that need a built-in default keymap. The XKB source files produced by
xkbcomp are fully resolved and can be used to verify that the files
which typically make up an XKB keymap are merged correctly or to create
a single file which contains a complete description of the keymap.
The source may specify an X display, or an .xkb or .xkm file; unless
explicitly specified, the format of destination depends on the format
of the source. Compiling a .xkb (keymap source) file generates a .xkm
(compiled keymap file) by default. If the source is a .xkm file or an
X display, xkbcomp generates a keymap source file by default.
If the destination is an X display, the keymap for the display is
updated with the compiled keymap.
The name of the destination is usually computed from the name of the
source, with the extension replaced as appropriate. When compiling a
single map from a file which contains several maps, xkbcomp constructs
the destination file name by appending an appropriate extension to the
name of the map to be used.
-a Show all keyboard information, reporting implicit or derived
information as a comment. Only affects .xkb format output.
-C Produce a C header file as output (.h extension).
-dflts Compute defaults for any missing components, such as key names.
Print msg before printing first error message.
Print msg at the start of each message line.
If there were any errors, print msg before exiting.
Show available options.
-Idir Specifies top-level directories to be searched for files
included by the keymap description. After all directories
specified by -I options have been searched, the current direc-
tory and finally, the default xkb directory
/usr/X11R7/lib/X11/xkb will be searched.
To prevent the current and default directories from being
searched, use the -I option alone (i.e. without a directory),
before any -I options that specify the directories you do want
If source or destination is a valid X display, load the keymap
from/into the device with the specified ID (not name).
-l List maps that specify the map pattern in any files listed on
the command line (not implemented yet).
-m name Specifies a map to be compiled from an file with multiple
-merge Merge the compiled information with the map from the server
(not implemented yet).
-o name Specifies a name for the generated output file. The default is
the name of the source file with an appropriate extension for
the output format.
Specifies a list of optional parts. Compilation errors in any
optional parts are not fatal. Parts may consist of any combi-
nation of the letters c, g,k,s,t which specify the compatibil-
ity map, geometry, keycodes, symbols and types, respectively.
-Rdir Specifies the root directory for relative path names.
-synch Force synchronization for X requests.
Print version number.
-w lvl Controls the reporting of warnings during compilation. A warn-
ing level of 0 disables all warnings; a warning level of 10
enables them all.
-xkb Generate a source description of the keyboard as output (.xkb
-xkm Generate a compiled keymap file as output (.xkm extension).
