By default will take the input from the input pipe (at XDG_RUNTIME_DIR/sxhkd_fifo) and
|
|
|
|
print the current sxhkd chain mode to stdout. That means, sxhkd needs to be started
|
|
|
|
with a fifo pipe running, ideally to the XDG_RUNTIME_DIR:
|
|
|
|
|
|
|
|
mkfifo \$XDG_RUNTIME_DIR/sxhkd_fifo && sxhkd -s \$XDG_RUNTIME_DIR/sxhkd_fifo
|
|
|
|
|
|
|
|
When given a key combination which maps to a specific mode, it will print out the name
|
|
|
|
of the mode instead. These maps can be passed with -c flag, specifying an options file.
|
|
|
|
By default it will look in \$XDG_CONFIG_HOME/sxhkd/sxhkd-chain-labels.conf
|
|
|
|
|
|
|
|
When passed the -o flag it will replace the contents of the file passed in with the
|
|
|
|
current sxhkd chain mode, emptying the file when no mode is active.
|
|
|
|
|
|
|
|
Default lookup places for files, in descending order:
|
|
|
|
:input fifo
|
|
|
|
\$SXHKD_FIFO (env variable)
|
|
|
|
\$XDG_RUNTIME_DIR/sxhkd_fifo
|
|
|
|
\$XDG_CACHE_HOME/sxhkd_fifo
|
|
|
|
~/.cache/sxhkd_fifo
|

|
|
~/.sxhkd_fifo
|
|
|
|
|
|
|
|
:label configuration
|
|
|
|
\$SXHKD_LABELCONFIG (env variable)
|
|
|
|
\$XDG_CONFIG_HOME/sxhkd/chain-labels.conf
|
|
|
|
~/.config/sxhkd/chain-labels.conf

\$XDG_CONFIG_HOME/sxhkd/sxhkdrc (parsing)
|
2020-05-26 09:46:53 +00:00
|
|
|
|
|
|
|
The label configuration file uses the following format:
|
2020-05-26 12:55:06 +00:00
|
|
|
mode name:key chain
|
2020-05-26 09:46:53 +00:00
|
|
|
|
2020-05-26 12:55:06 +00:00
|
|
|
Lines beginning with a # will be ignored. Whitespace is important, sxhkd will, by
|
|
|
|
default, put a single space between any component of the key combination.
|
2020-05-26 09:46:53 +00:00
|
|
|
|
2020-05-26 12:55:06 +00:00
|
|
|
An example file chain-labels.conf:
|
2020-05-26 09:46:53 +00:00
|
|
|
media:super + alt + m
|
|
|
|
system:super + backspace
|
|
|
|
|
2020-05-26 12:55:06 +00:00
|
|
|
Instead of using an explicit configuration file, you can put the chain mode
|
|
|
|
information into the regular sxhkdrc as comments. They need to follow this exact format:
|
|
|
|
# mode:mode name:key chain
|
|
|
|
|
|
|
|
They can occur anywhere in the file. The space before mode is necessary, and # needs to
|
|
|
|
be the first character on the line. The above example file as written into the sxhkdrc:
|
|
|
|
# mode:media:super + alt + m
|
|
|
|
# mode:system:super + backspace
|
|
|
|
|
|
|
|
If an explicit configuration file exists, it will supersede any mode information in the
|
|
|
|
sxhkdrc file.
