## Advanced Usage of `--regex-cmd`
|
||||
|
||||
If the regex provided to `swaybar_info` has two captures, the first capture will
|
||||
be used as the text to be displayed, and the second capture will be expected to
|
||||
be the color string (such as FFFFFF for white, or 44FF44 for a lighter green).
|
||||
|
||||
For example, if the script invoked with `--regex-cmd` has output like the
|
||||
following:
|
||||
|
||||
MPD Title | MPD Album | playingCOLORSPLIT44FF44
|
||||
|
||||
That sometimes becomes:
|
||||
|
||||
MPD is not running
|
||||
|
||||
Then this text can be parsed with a regex like:
|
||||
|
||||
status_command $HOME/.config/sway/swaybar_info \
|
||||
'--regex-cmd=$HOME/scripts/mpc/mpcCommand.sh[SPLIT]simple[SPLIT]^\(.\*?\)\(?:COLORSPLIT\)?\([A-F0-9]{6}\)?$'
|
||||
|
||||
Note that some characters like `*` or `(` had to be escaped because they are
|
||||
being passed verbatim to a shell.
