Recently, I switched to NixOS and realised that there is no G'MIC plugin package for Krita.
There's this issue that was last active in October 2023.
I was wondering if anyone has managed to install this without using another package manager (such as Flatpak) or installing an AppImage manually, for system reproducibility, and I also don't wanna have two package managers in one system.
Ideally, there'd be a wrapper, so you could do something like:
I haven't used Krita. But I can tell you that those wrappers are "options" defined by NixOS modules. There is documentation for writing them in the NixOS Manual.
Built-in NixOS options are documented in the Configuration Options Appendix with links to implementations which provide helpful examples when writing your own options.
