To enable the `tokyonight` colorscheme for `Lightline`:

```vim
" Vim Script
let g:lightline = {'colorscheme': 'tokyonight'}
```

## ⚙️ Configuration

> ❗️ configuration needs to be set **BEFORE** loading the color scheme with `colorscheme tokyonight`

The theme comes in three styles, `storm`, a darker variant `night` and `day`.

The **day** style will be used if:

- `vim.g.tokyonight_style = "day"`
- or `vim.o.background = "light"`

-- Load the colorscheme
vim.cmd[[colorscheme tokyonight]]
```

```vim
" Example config in VimScript
let g:tokyonight_style = "night"
let g:tokyonight_italic_functions = 1
let g:tokyonight_sidebars = [ "qf", "vista_kind", "terminal", "packer" ]

" Change the "hint" color to the "orange" color, and make the "error" color bright red
let g:tokyonight_colors = {
  \ 'hint': 'orange',
  \ 'error': '#ff0000'
\ }

" Load the colorscheme
colorscheme tokyonight
```

### Making `undercurls` work properly in **Tmux**

To have undercurls show up and in color, add the following to your **Tmux** config file:

```sh
# Undercurl
set -g default-terminal "${TERM}"
set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours - needs tmux-3.0
```

## 🍭 Extras

Extra color configs for **Kitty**, **Alacritty**, **Fish**, **WezTerm**, **iTerm** and **foot** can be found in [extras](extras/). To use them, refer to their respective documentation.

You can easily use the color palette for other plugins inside your Neovim config:

```lua
local colors = require("tokyonight.colors").setup({}) -- pass in any of the config options as explained above
local util = require("tokyonight.util")

aplugin.background = colors.bg_dark
aplugin.my_error = util.brighten(colors.red1, 0.3)
```

## 🔥 Contributing

Pull requests are welcome. For the `extras`, we use a simple template system that can be used to generate themes for the different styles.

How to add a new extra template:

1. create a file like `lua/tokyonight/extra/cool-app.lua`
2. add the name and output file extension to the `extras` table in `lua/tokyonight/extra/init.lua`
3. in the root directory, run `$ lua lua/tokyonight/extra/init.lua` to generate / update extra themes
4. commit the newly created themes under `extra/`
