🌈 colorbox.nvim

require commons.nvim luarocks ci.yml collect.yml codecov

Do you want all the most popular (Neo)Vim colorschemes than only one? Do you want to change them from time to time?

This is it! Let's load all the ultra colorschemes into Neovim player!

shuffle-per-sec-v2.mp4
Click here to see how to configure 
require("colorbox").setup({
  policy = { seconds = 1, implement = "shuffle" },
  timing = "interval",
})

It uses GitHub actions to weekly collect/update the colorscheme dataset.

Note

The most popular colorschemes are picked from below websites:

With below conditions:

  1. GitHub stars ≥ 500 (by default it only enable ≥ 800, see Configuration).
  2. Last git commit is in last 5 years.
  3. For multiple plugins that contain a same color name, it picks by following rules:
    1. The awesome-neovim wins the vimcolorschemes (they usually support modern Neovim features).
    2. More github stars.
    3. Newer git commits.

Please check COLORSCHEMES.md for full colorscheme dataset.

It installs colorschemes via git submodule instead of copy-paste source code, so you get continuously updates from original authors.

It allows you to play them with multiple playback settings(policies):

  • Suffle playback.
  • Play in order.
  • Play in reverse order.
  • Single cycle.

And multiple trigger timings:

  • On startup.
  • Fixed interval.
  • Date time (todo).
  • By filetype.

✅ Requirements

Note

This plugin always supports with the latest stable and (possibly) nightly Neovim version.

  • Neovim ≥ 0.10.
  • Git.

📦 Install

Important

If this plugin provides the main colorscheme (i.e. the color show right after nvim start), then make sure:

  1. Don't lazy load it.
  2. Load it before all other plugins.

Important

Some colorschemes have specific requirements:

Please manually add these dependencies if you enable them.

With lazy.nvim 
require('lazy').setup({
  {
    'linrongbin16/colorbox.nvim',

    -- don't lazy load
    lazy = false,
    -- load with highest priority
    priority = 1000,

    build = function() require("colorbox").update() end,
    config = function() require("colorbox").setup() end,
  }
})
With pckr.nvim 
require('pckr').add({
  {
    'linrongbin16/colorbox.nvim',

    run = function() require("colorbox").update() end,
    config = function() require("colorbox").setup() end,
  };
})

🎬 How it Works

When loading this plugin, it does below steps:

  1. Runs the filters, only enables the colors you choose from the dataset (see Filter).
  2. Registers the triggers to invoke related policies at a proper timing (see Timing).

When a timing is triggered, it does below steps:

  1. Runs the registered policy and pick a colorscheme (see Policy).
  2. Refreshes the background option (see Background).
  3. Runs the colorscheme command to actually apply the colorscheme.

🚀 Usage

You can use the Colorbox command with below subcommands:

  • update: Update all git submodules.

  • info: Show detailed information and configured status.

    Note: use scale=0.7 to specify popup window's size in range (0, 1], by default is scale=0.7.

  • shuffle: Change to a random color.

Note

You can still use the colorscheme command to change a colorscheme.

🔧 Configuration

To configure options, please use:

require("colorbox").setup(opts)

The opts is an optional lua table that override the default options. Here we only introduce some of the most options.

For complete default options, please see configs.lua.

Filter

The filter option is to help user filter some colorschemes from the dataset, thus they will never show up.

There're 3 kinds of filters:

  • Builtin filter: A lua string that presents the name of a builtin filter. For now we only have the "primary" builtin filter, it only enables the primary color in a plugin, filters all other color variants (when there're multiple colors in one plugin).

  • Function filter: A lua function that decides whether to enable/disable a color. It uses the function signature:

    function(color:string, spec:colorbox.ColorSpec):boolean

    The function has two parameters:

    It returns true to enable a color, false to disable a color.

  • List filter: A lua list that contains multiple function filters and builtin filters. A colorscheme will only be enabled if all these filters returns true.

Timing

The timing option is to configure when to change to next colorscheme.

There're 3 kinds of timings:

  • startup: On nvim start. It works exactly like manually adding the script colorscheme xxx in nvim's init config file.
  • interval: On fixed interval timeout. It registers a background job to schedule on a fixed interval timeout (i.e. every X seconds), and triggers the next colorscheme.
  • filetype: On file type change. It listens to current buffer's file type, and triggers the next colorscheme if the file type changed.

Policy

The policy option is to configure how to pick the next colorscheme.

There're 3 kinds of policies (they work with the corresponding timings):

  • Builtin policy: A lua string that presents the name of a builtin policy. For now we have 4 builtin policies (see below). It can works directly with the startup timing (see: Choose random color on nvim start).

    • shuffle: Pick a random color.
    • in_order: Pick next color in order, color names are ordered from 'A' to 'Z'.
    • reverse_order: Pick next color in reversed order, color names are ordered from 'Z' to 'A'.
    • single: Always pick the same color, i.e. next color is still the current color.

  • Fixed interval timeout policy: A lua table that contains seconds and implement fields. It works with the interval timing (see: Change random color per second).

    • seconds: Choose next colorscheme on every X seconds.
    • implement: The name of the builtin policy that choose how to pick the next colorscheme.

  • File type policy: A lua table that contains mapping and (optional) empty and (optional) fallback fields. It works with the filetype timing (see: Choose color by file type).

    • mapping: A lua table that maps from file type to color name. When current buffer's file type is hitted, it changes to the mapped color.
    • (Optional) empty: The color name when the file type is empty lua string. When set to nil, it does nothing.
    • (Optional) fallback: The color name when the file type is not found in mapping field. When set to nil, it does nothing.

Background

The background option runs set background=dark/light every time before running the colorscheme command (to change a colorscheme).

require("colorbox").setup({
  background = "dark",
})

Some colors (tokyonight-day, rose-pine-dawn, etc) are forced to be light, i.e. they forced the background option to light inside their internal implementations.

This is no problem, except some user may want all those following colorschemes (after tokyonight-day and rose-pine-dawn) go back to dark background if they're dark-able.

Hook

To execute a hook function after policy is triggered and new colorscheme is applied, please use:

require("colorbox").setup({
  post_hook = function(color, spec)
    vim.notify(string.format("Colorscheme changed to: %s", vim.inspect(color)))
  end,
})

The hook accepts a lua function with below signature:

function(color:string, spec:colorbox.ColorSpec):nil
