🌓 auto-gnome-theme.nvim

A simple, zero-polling Neovim plugin to automatically switch your colorscheme and background based on the Gnome system's light/dark mode preference.

It utilizes gsettings monitor to listen for system events, ensuring instantaneous and resource-efficient theme switching.

Prerequisites

This plugin is specifically designed for the Gnome desktop environment (or any environment that exposes the theme setting via gsettings).

Installation

Using lazy.nvim

{
    "itsfernn/auto-gnome-theme.nvim",
  -- Ensure your chosen themes are installed!
  dependencies = { 
    -- "folke/tokyonight.nvim", 
    "rose-pine/neovim",
  },
  
  -- Configuration runs after the plugin is loaded
  config = function()
    require("auto-gnome-theme").setup({
      -- See Configuration section below
      theme = "rose-pine"
      -- dark_theme = "tokyonight",
      -- light_theme = "rose-pine",
    })
  end,
}

Configuration

The setup() function accepts a table with theme configuration.

1. Single Theme Switching

Some themes like rose-pine already have both a light and dark theme. In this case the theme is only loaded on startup and only the vim.o.background is set dynamically.

require("auto-gnome-theme").setup({
  theme = "rose-pine", -- Applies Rose Pine for both dark and light mode
})
-- When the system is dark, vim.o.background is set to 'dark', and vice versa.

2. Dual Theme Switching

You can also specify two entierly different colorschemes for light and dark modes.

require("auto-gnome-theme").setup({
  dark_theme = "tokyonight",   -- Applies only when system is in Dark Mode
  light_theme = "catppuccin",  -- Applies only when system is in Light Mode
})

Here’s a concise note you can add to the README to explain the relevance of your plugin in light of the new Neovim and tmux features:

Note

Recent versions of Neovim (see commit d460928) now support automatic theme switching based on the terminal’s light/dark mode (if your terminal supports it). However, auto-gnome-theme.nvim still offers some advantages:

• Granular control: choose entirely different themes for light and dark modes, or use themes that have seperate dark / light themes.
• No flashing colors on startup when using a light theme.
