Lua script for set color label on group images
--[[
Set color labels to group
Script to provide shortcuts for setting color labels in images groups.
Useful for those who are RAW+JPEG shooters.
Installation and usage:
1. Copy this file into ~/.config/darktable/lua/
2. Add `require "colorlabel_group"` to new line in ~/.config/darktable/luarc
3. Restart darktable
4. Assign a keyboard shortcut to each action via daktable preferences > shortcuts > lua
I use the following shortcuts:
Set group red - CRTL+F1
Set group yellow - CRTL+F2
Set group green - CRTL+F3
Set group blue - CRTL+F4
Set group purple - CRTL+F5
