Rainbow delimiters for Neovim with Tree-sitter
594e88ba1d
Creating and removing symlinks is brittle because the symlink might get left over and mess up subsequent tests. This change makes it so that the path to the plugin is injected into the runtime path at startup. |

.. default-role:: code ############################### Rainbow delimiters for Neovim ############################### This Neovim plugin provides alternating syntax highlighting (“rainbow parentheses”) for Neovim, powered by `Tree-sitter`_. The goal is to have a hackable plugin which allows for different configuration of queries and strategies, both globally and per file type. Users can override and extend the built-in defaults through their own configuration. This is a fork of `nvim-ts-rainbow2`_, which was implemented as a module for `nvim-treessiter`_. However, since nvim-treesitter has deprecated the module system I had to create this standalone plugin. Installation and setup ###################### Installation ============ Install it like any other Neovim plugin. You will need a Tree-sitter parser for each language you want to use rainbow delimiters with. Setup ===== No configuration is needed to get started, this plugin has reasonable defaults which you can override. Configuration is done by setting entries in the Vim script dictionary `g:rainbow_delimiters`. Here is an example configuration: .. code:: vim let g:rainbow_delimiters = { \ 'strategy': { \ '': rainbow_delimiters#strategy.global, \ 'vim': rainbow_delimiters#strategy.local, \ }, \ 'query': { \ '': 'rainbow-delimiters', \ 'lua': 'rainbow-blocks', \ }, \ 'priority': { \ '': 110, \ 'lua': 210, \ }, \ 'highlight': [ \ 'RainbowDelimiterRed', \ 'RainbowDelimiterYellow', \ 'RainbowDelimiterBlue', \ 'RainbowDelimiterOrange', \ 'RainbowDelimiterGreen', \ 'RainbowDelimiterViolet', \ 'RainbowDelimiterCyan', \ ], \ } The equivalent code in Lua: .. code:: lua -- This module contains a number of default definitions local rainbow_delimiters = require 'rainbow-delimiters' ---@type rainbow_delimiters.config vim.g.rainbow_delimiters = { strategy = { [''] = rainbow_delimiters.strategy['global'], vim = rainbow_delimiters.strategy['local'], }, query = { [''] = 'rainbow-delimiters', lua = 'rainbow-blocks', }, priority = { [''] = 110, lua = 210, }, highlight = { 'RainbowDelimiterRed', 'RainbowDelimiterYellow', 'RainbowDelimiterBlue', 'RainbowDelimiterOrange', 'RainbowDelimiterGreen', 'RainbowDelimiterViolet', 'RainbowDelimiterCyan', }, } Please refer to the `manual`_ for more details. For those who prefer a `setup` function there is the module `rainbow-delimiters.setup` that accepts all the same parameters as `g:rainbow-delimiters`. .. code:: lua require('rainbow-delimiters.setup').setup { strategy = { -- ... }, query = { -- ... }, highlight = { -- ... }, } Help wanted ########### There are only so many languages which I understand to the point that I can write queries for them. If you want support for a new language please consider contributing code. See the CONTRIBUTING_ for details. Status of the plugin #################### Tree-sitter support in Neovim is still experimental. This plugin and its API should be considered stable insofar as breaking changes will only happen if changes to Neovim necessitates them. License ####### Licensed under the Apache-2.0 license. Please see the `LICENSE`_ file for details. Migrating from nvim-ts-rainbow2 ############################### Rainbow-Delimiters uses different settings than nvim-ts-rainbow2, but converting the configuration is straight-forward. The biggest change is where the settings are stored. - Settings are stored in the global variable `g:rainbow-delimiters`, which has the same keys as the old settings - The default strategy and query have index `''` (empty string) instead of `1` - Default highlight groups have the prefix `RainbowDelimiter` instead of `TSRainbow`, e.g. `RainbowDelimiterRed` instead of `TSRainbowRed` - The default query is now called `rainbow-delimiters` instead of `rainbow-parens` - The public Lua module is called `rainbow-delimiters` instead of `ts-rainbow` The name of the default query is now `rainbow-delimiters` because for some languages like HTML the notion of "parentheses" does not make any sense. In HTML the only meaningful delimiter is the tag. Hence the generic notion of a "delimiter".
