[Feature]: Auto generate theme colorse based on users

[EatedPantsu]

Description

A python script that detects users colors from kdeglobals or gtk colors.css and generates a theme based on provided template. It also tries to see what font user is using and copies that so you can manually place it in prefix.

How should we implement this?

Once you run kde_gen.py or gtk_gen.py or both, they make a theme(s) file(s) based on template.qss and copy user font next to created themes so user cna place the fileto their prefix if they wish.
It fallback to arial if not.

This works for KDE using kdeglobals and with GTK colors from ~/.config/gtk-3.0/colors.css

I've change template.qss to template.txt as github does not allow qss files to be uplaoded, so rename it

kde_gen.py
gtk_gen.py
template.txt

Examples

got inspiration from this project https://github.com/shy1132/gtk2wine but is different and can be used to import GTK theme into wine prefix registry.

Additional Notes

Probably works best with KDE.
Even this is not perfect (generally in my experience trying to make apps look the same across wine, GTK, QT, KDE...is THE pain) and has flaws but it helps with consistent look for me and might be useful to others and someone who knows what they're doing might fix and improve this and hopefully it gets integrate with Linux installer script for MO2.

I have made this myself but faced many issues and used AI to fix them and edit files.

some examples of imported/generated colors (I forgot to change the accent color so it's the same):

This is sick! I'll definitely look into tossing this is in alongside #792! (when I get to that)
Or if ya wanna fork rewrite and make a PR so you can get the contrib credits, that would be great too!

It woudl be awesome for you to include it in rewrite!

I am not skilled enough for a such task but I do not have any issues for anyone who is to use this code as his own and gets all the credits. I'll just be happy if it improves experience and especially if someone improves the whole thing.

I can share some ideas I had but was not skilled enough or to lazy to implement them.

For example, qss template has a lot of room for improvements and additions and options- such as:
-option for choosing rounded/square corners/scrolbars if wanted
-size of different things (tabs, boxes, buttons)
-better mapping of Linux colors to theme so more contrast/readability
-icons- colorful, monochrome light/dark...maybe even symlinking and using users breezea/adwaita?

Template is basically just a theme file structured so python can insert colors it pick up from kdeglobals or colors.css- so in essence a theme without any actually color info but place holders.

So someone skilled enough with css/qss could make a theme (or a few, like rounded/square option and compact/comfortable etc) or snippets that could be inserted in a final theme template and then filled with users colors.

The python scripts for now choose colors based on my own choosing from colors:window, colors:view etc parameters. There might be better option, i do not know.
Same for colors.css for gtk.

I also do not know if it woudl even work on gnome based DE...i think it should if it has colors.css somewhere and you point script to it.
Or it could look into qt colors maybe with some changes...

so logic is this

kde_gen.py ---> kdeglobals \
                            \
                             --insert into-> template.qss OR template2.qss etc---> mo2_theme.qss, fontfile.tff
                            / 
gtk_gen.py ---> colors.css /

Automation could place those file where they need to go, windows/fonts in prefix and mo2 folder/style-sheets.
It should detect users DE or let user choose, like with

echo $XDG_CURRENT_DESKTOP

or python

import os
de = os.environ.get("XDG_CURRENT_DESKTOP") \
     or os.environ.get("DESKTOP_SESSION") \
     or os.environ.get("KDE_FULL_SESSION") \
     or os.environ.get("GDMSESSION") \
     or "unknown"

print(f"Desktop Environment: {de}")

and then choose appropriate script or if one jump to section for it.

With a GOOD (better than currently) template and scripts as they are now, it should already be appropriate for most users and they woudl end up with solid theme. Even now I think it is passable to use.

Cheers!
