[BUG] Configured colorscheme is not used by default

Description

Setting the default colorscheme to nord via colorschemes.nord.enable doesn't work, while the colorscheme gets installed and can be switched to by doing :colorscheme nord, the default Neovim colorscheme is used by default.

I have also tested with colorschemes.cyberdream.enable and got the same result.

Minimal, Reproducible Example (MRE)

{
  programs.nixvim = {
    enable = true;

    colorschemes.nord.enable = true;
  };
}

As a temporary fix, you can use the following option

programs.nixvim = {
  extraConfigLuaPost = ''vim.cmd [[ colorscheme nord ]]'';
};

if you want

This should already be done by mkVimPlugin:

Perhaps the generated lua code is ending up in the wrong part of init.lua and is not having the desired effect 🤔

mkVimPlugin sets our colorscheme option:

nixvim/lib/vim-plugin.nix

Lines 115 to 117 in 929bb0c

	(lib.optionalAttrs (isColorscheme && (colorscheme != null)) {
	colorscheme = lib.mkDefault colorscheme;
	})

Our colorscheme option adds the code to extraConfigVim:

nixvim/modules/colorscheme.nix

Lines 12 to 14 in 929bb0c

	extraConfigVim = ''
	colorscheme ${config.colorscheme}
	'';

Our content option sandwiches extraConfigVim between extraConfigLuaPre and extraConfigLua:

nixvim/modules/output.nix

Lines 113 to 121 in 929bb0c

	if config.type == "lua" then
	# Lua
	helpers.concatNonEmptyLines [
	config.extraConfigLuaPre
	(helpers.wrapVimscriptForLua config.extraConfigVim)
	config.extraConfigLua
	config.extraConfigLuaPost
	]
	else

You can inspect the final generated lua yourself using nixvim-print-init.

Checking the output of nixvim-print-init I see that the first place colorscheme appears is like so

 143   vim.cmd([[let $BAT_THEME = 'nord'
 144
 145   colorscheme nord
 146   ]])

Which from the line numbers (143-146) happens early on, so is probably the one that is added automatically and thus the one not working. Then the very last line is just vim.cmd([[ colorscheme nord ]]) which I assume is the one I manually added with extraConfigLuaPost.

This might actually be a regression in colorscheme. I just updated my system for the first time a while and I noticed my colors were off. I have been using:

programs.nixvim = {
  enable = true;

  colorscheme = "solarized-flat";
  extraPlugins = [ pkgs.vimPlugins.nvim-solarized-lua ];

  # Rest of config
};

I can check my flake.lock for a potential bisect if it helps.
