wezterm: configuration with nix

[nikitarevenco]

WezTerm's configuration is in lua but it's not very complicated and can be represented with a static format. For example here is my WezTerm configuration:

local wezterm = require("wezterm")
local config = wezterm.config_builder()

config.color_scheme = "Catppuccin Mocha"
config.font_size = 13
config.font = wezterm.font("JetBrainsMono Nerd Font")
config.window_close_confirmation = "NeverPrompt"
config.window_decorations = "RESIZE"
config.automatically_reload_config = false
config.swallow_mouse_click_on_window_focus = true
config.window_padding = {
	left = 0,
	right = 0,
	top = 0,
	bottom = 0,
}

config.adjust_window_size_when_changing_font_size = false

config.keys = {
	{
		key = "F11",
		action = wezterm.action.ToggleFullScreen,
	},
	{
		key = "+",
		mods = "CTRL",
		action = wezterm.action.IncreaseFontSize,
	},
	{
		key = "-",
		mods = "CTRL",
		action = wezterm.action.DecreaseFontSize,
	},
	{
		key = "=",
		mods = "CTRL",
		action = wezterm.action.ResetFontSize,
	},
	{ key = "LeftArrow", mods = "OPT", action = wezterm.action({ SendString = "\x1bb" }) },
	{ key = "RightArrow", mods = "OPT", action = wezterm.action({ SendString = "\x1bf" }) },
	{
		key = "\\",
		mods = "CTRL",
		action = wezterm.action.ActivateCopyMode,
	},
	{
		key = "Backspace",
		mods = "CTRL",
		action = wezterm.action.SendKey({ mods = "CTRL", key = "w" }),
	},
}

config.char_select_font_size = 13
config.char_select_fg_color = "#cdd6f4"
config.char_select_bg_color = "#1e1e2e"

config.selection_word_boundary = " \t\n{}[]()\"'`,;:@│┃*…$"
config.audible_bell = "Disabled"
config.hide_tab_bar_if_only_one_tab = true

config.default_cursor_style = "SteadyBar"

return config

As you can see it's just keys and values, so generating a wezterm.lua file from a nix object shouldn't be hard, at least for the simple changes.

For more complex changes people can always use extraConfig options.

For someone who is familiar with writing Nix packages, it would be awesome if you expanded wezterm.nix: https://github.com/nix-community/home-manager/blob/release-24.05/modules/programs/wezterm.nix
