wly_colpick

A yad script for wlroots compositors to choose a color anywhere on screen

about

This is a simple bash GUI script that works for *nix distributions that run a wlroots based wayland compositor such as labwc, sway, wayfire, hyperland et al.

build

make install

That's it!

You can install using DESTDIR then roll your own package such that your package manager can keep track of things. PREFIX=/usr is also accepted.

dependencies

• yad
• netpbm (ppmtoxpm)
• slurp
• grim
• bash
• sed
• grep

optional

• rgb.txt

This is actually not needed, but if you have it you are forced to use it!

Most distros with a wlroots compositor ship with these, except perhaps netpbm.

usage

In a wayland session this can be invoked from menu, shortcut or CLI. A yad GUI pops where the user can use the select button to fetch the color. The cursor should change to a crosshair, then hover over the area where you want to grab the color and click. A GUI is returned showing the color in hex, rgb() and decimal formats with a color swatch giving some visual feedback (for example: #F4D131, rgb(244,209,49), 0.956 0.819 0.192 respectively). It does rely on rgb.txt when named colors such as gray20 occur, which the script tries to find but if it is in a non standard location you can tell the script in a configuration file at ~/.config/colpick.conf with the contents:

rgb_text=/full/path/to/rgb.txt

If you delete rgb.txt the script will work faster!

Report them here in issues or fix them and issue a pull request .

to do

• gettext (NLS)
• reduce dependency on bash, sed, grep; ie: more pure shell
