🌈 nvim-ts-rainbow 🌈

Rainbow parentheses for neovim using tree-sitter. This is a module for nvim-treesitter, not a standalone plugin. It requires and is configured via nvim-treesitter

Should work with any language supported by nvim-treesitter. If any language is missing, please open an issue/PR.

Installation and setup

Install this plugin, then add a rainbow section in the call to require("nvim-treesitter.configs").setup():

require("nvim-treesitter.configs").setup {
  highlight = {
      -- ...
  },
  -- ...
  rainbow = {
    enable = true,
    extended_mode = true, -- Also highlight non-bracket delimiters like html tags, boolean or table: lang -> boolean
    max_file_lines = nil, -- Do not enable for files with more than n lines, int
    -- colors = {}, -- table of hex strings
    -- termcolors = {} -- table of colour name strings
  }
}

Colours

I've used the gruvbox palette because it is nice and subtle. I wanted to use VIBGYOR for an actual rainbow, but

• indigo and blue look the same.
• the colours were too bright and distracting.

To change the colors you can edit lua/rainbow/colors.lua or add following code to setup

require'nvim-treesitter.configs'.setup{
  rainbow = {
    -- Setting colors
    colors = {
      -- Colors here
    },
    -- Term colors
    termcolors = {
      -- Term colors here
    }
  },
}

If you want to override some colours (you can only change colours 1 through 7 this way), you can do it in your init.vim: (thanks @delphinus !). You can also use this while writing a colorscheme
