Lua script for tracking the Git status of files.

[danielschudel]

I use Git to archive/distribute all my XMP files and my best RAW files. I wanted visual indicators in Darktable that would tell me an image's Git status (untracked, staged, committed, etc.). This Lua add-on does that with the color flags (red/yellow/green) and the "Image Information" box.

Additionally - simple "git add/remove" widget is available to manage individual files.

More details are in the comments of the new git.lua file.
