module request: wallust

[KiaraGrouwstra]

Description

wallust is a tool to tweak application themes, either from theme files or generated from a wallpaper.

it would be nice to see a module programs.wallust for configuring its settings.

Hi, I'm not one of the assignees, but I'm willing to create a module for that. Do you use normally wallust? Have you encountered any issues because of HM inmutable config files?

I haven't use wallust before, so if it's not too much trouble, could you explain how it works?

[KiaraGrouwstra]

@aguirre-matteo good question! and it seems not trivial. some applications allow multiple configuration files, some configuration formats (sh, css, conf, rasi, xresources) offer include commands to import another file. for other common formats, I haven't yet found a way to gracefully compose with home-manager - one would need to essentially have template vs generated versions of config files. I'm not sure I know a general solution, but prior art here seems the pywal module.

[aguirre-matteo]

@KiaraGrouwstra Do you know what files wallust creates? I've checked out some videos/screenshots and found out that wallust places the resultant config files at ~/.config, so this should fail because those files are immutable.

Do you know if there's a way to change the destination path? If it's possible, it should be trivial to apply most of the configuration (sourcing the files, like Pywal's module does).

[aguirre-matteo]

By the way, what advantages wallust over stylix or other already implemented ricing tools? If you're aiming to have a setup where the wallpaper changes constantly, and the color palette follows it, it could be hard because most config files are immutable. Probably it's possible, but maybe you'll need to restart the window manager.

[KiaraGrouwstra]

@aguirre-matteo yes, the config allows you to specify where you want to put things.

the use-case is indeed switching themes without having to rebuild.

it looks like the pywal module has so far focused on applications doing configuration formats that support including external configuration files.
