uniformly apply catppuccin to as many things as possible

[KerryCerqueira]

Theme should apply to shell, nvim, hyprland, GTK, KDE.

96ea88d does this for nvim.

Recipe for theming qt:

• qtwayland package for wayland support for e.g. dolphin
• qtsvg for svg icon theme support in qt
• qt home manager module set as follows:

  {
  enable = true;
  platformTheme.name = "kvantum";
  style.name = "kvantum";
  }

  This installs kvantum and directs qt apps to have their style set by it.

• Include catppuccin flake and either enable its home module options for qt or the global one. This configures the kvantum supplied colourscheme to be catppuccin.
• Include qt6ct and set environment variable QT_QPA_PLATFORMTHEME to qt6ct.
• Set the font and icon theme in qt6ct or declaratively with ~/.config/qt6ct/qt6ct.conf. Also set the style to kvantum.

We need two configuration apps for qt and both need to be bullied into declarativity with extra configs. This fucking blows.

While we're at it, finish configuring dolphin by installing its dependencies:

• konsole, for the in app terminal.
• KIO slaves, for network interfaces.
• various thumbnailers, for file previews.
• kompare for file diffs
• baloo for metatag searches
• udisks for the disk/partition interface.
• paste the following into ~/.config/kdeglobals:

  [General]
  TerminalApplication=kitty

  so that the popout terminal in dolphin is kitty.

• Apply a theme and font to konsole so that it looks like kitty.

This is slightly less shit.

The only reason we use kvantum is because we're trying to cajole the catppuccin global option to work for qt. It may be better to either use the specific qt option in the HM module and see if that works, or to feed a catppuccin theme directly to qt6ct or the qt home manager module (which again uses kvantum).

Recipe for theming gtk is simpler. Just use the gtk home manager module which has a catppuccin option. Bad news: this option is deprecated as the underlying package is now unsupported.

• kitty
• rofi

• 50
