xcompose 0.5.1

Utility for managing X11 compose key sequences

xcompose

Simple utilities to help configure X11 compose key sequences.

The repo also hosts a very extensive .XCompose file with over 42 000 new sequences; more details here.

Installation

$ pip install xcompose

Requirements

Currently assumes that the system compose key configurations are in /usr/share/X11/locale/, while the keysym definitions are in /usr/include/X11/keysymdef.h.

Only tested on Ubuntu 24, but should work more widely (though still very much beta quality).

Usage

$ xcompose -h
usage: xcompose [-h] [-f FILE | -S] [-i] [-k KEY] [-s SORT] {add,find,get,validate} ...

XCompose sequence helper utility.

positional arguments:
  {add,find,get,validate}
    add                 print a new compose sequence
    find                find sequences matching given output
    get                 get sequences matching given key inputs
    validate            validate compose config file

options:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  config file to analyze (instead of user config)
  -S, --system          analyze system config (instead of user config)
  -i, --ignore-include  don't follow any include declarations in the config
  -k KEY, --key KEY     modifier key keysym (default is Multi_key; use ANY for all)
  -s SORT, --sort SORT  sort resulting sequences (options: 'keys', 'value')

Examples

$ xcompose find é
<Multi_key> <acute> <e>			: "é"	eacute # LATIN SMALL LETTER E WITH ACUTE
<Multi_key> <e> <acute>			: "é"	eacute # LATIN SMALL LETTER E WITH ACUTE
<Multi_key> <apostrophe> <e>		: "é"	eacute # LATIN SMALL LETTER E WITH ACUTE
<Multi_key> <e> <apostrophe>		: "é"	eacute # LATIN SMALL LETTER E WITH ACUTE

$ xcompose find pound
<Multi_key> <L> <minus>			: "£"	sterling # POUND SIGN
<Multi_key> <minus> <L>			: "£"	sterling # POUND SIGN
<Multi_key> <l> <minus>			: "£"	sterling # POUND SIGN
<Multi_key> <minus> <l>			: "£"	sterling # POUND SIGN

$ xcompose find U+00B5
<Multi_key> <m> <u>			: "µ"	mu # MICRO SIGN
<Multi_key> <slash> <u>			: "µ"	mu # MICRO SIGN
<Multi_key> <u> <slash>			: "µ"	mu # MICRO SIGN

$ xcompose get / =
<Multi_key> <slash> <equal>		: "≠"	U2260 # NOT EQUAL TO

$ xcompose --sort keys get /
<Multi_key> <slash> <minus>		: "⌿"	U233f # / - APL FUNCTIONAL SYMBOL SLASH BAR
<Multi_key> <slash> <slash>		: "\\"	backslash # REVERSE SOLIDUS
<Multi_key> <slash> <less>		: "\\"	backslash # REVERSE SOLIDUS
<Multi_key> <slash> <equal>		: "≠"	U2260 # NOT EQUAL TO
<Multi_key> <slash> <B>			: "Ƀ"	U0243 # LATIN CAPITAL LETTER B WITH STROKE
<Multi_key> <slash> <C>			: "₡"	U20a1 # COLON SIGN
<Multi_key> <slash> <D>			: "Đ"	Dstroke # LATIN CAPITAL LETTER D WITH STROKE
⋮
<Multi_key> <slash> <U2194>		: "↮"	U21AE # LEFT RIGHT ARROW WITH STROKE
<Multi_key> <slash> <U2395>		: "⍁"	U2341 # / ⎕ APL FUNCTIONAL SYMBOL QUAD SLASH

$ xcompose add ɕ c @
<Multi_key> <c> <at> : "ɕ"  U0255   # LATIN SMALL LETTER C WITH CURL

$ xcompose add ć c /
<Multi_key> <c> <slash> : "ć"  U0107   # LATIN SMALL LETTER C WITH ACUTE (conflicts with ¢)

$ echo '<Multi_key> <c> <comma> <quote> : "ḉ"' >> ~/.XCompose  # add a line to .XCompose

$ xcompose validate

Formatting

There is also a separate utility for helping format configs so that definitions line up nicely.

$ xcfmt -h
usage: xcfmt [-h] [-o FILE] [-k N] [-v N] [FILE]

XCompose config formating utility.

positional arguments:
  FILE                  file to format (uses stdin if unspecified)

options:
  -h, --help            show this help message and exit
  -o FILE, --output FILE
                        file to write output to (uses stdout if unspecified)
  -k N, --max-key-indent N
                        maximum indentation up to the colon (default: 40)
  -v N, --max-value-indent N
                        maximum indentation up to the comment (default: 10)
