nvim-treesitter

Treesitter configurations and abstraction layer for Neovim.

[!CAUTION] The master branch is frozen and provided for backward compatibility only. All future updates happen on the main branch, which will become the default branch in the future.

The goal of nvim-treesitter is both to provide a simple and easy way to use the interface for tree-sitter in Neovim and to provide some basic functionality such as highlighting based on it:

Traditional highlighting (left) vs Treesitter-based highlighting (right). More examples can be found in our gallery.

Warning: Treesitter and nvim-treesitter highlighting are an experimental feature of Neovim. Please consider the experience with this plug-in as experimental until Tree-Sitter support in Neovim is stable! We recommend using the nightly builds of Neovim if possible. You can find the current roadmap here. The roadmap and all features of this plugin are open to change, and any suggestion will be highly appreciated!

Nvim-treesitter is based on three interlocking features: language parsers, queries, and modules, where modules provide features – e.g., highlighting – based on queries for syntax objects extracted from a given buffer by language parsers. Users will generally only need to interact with parsers and modules as explained in the next section. For more detailed information on setting these up, see “Advanced setup”.

Quickstart

Requirements

Neovim 0.10 or later (supported up to Neovim 0.12);
tar and curl in your path (or alternatively git);
a C compiler in your path and libstdc++ installed (Windows users please read this!).

Installation

You can install nvim-treesitter with your favorite package manager (or using the native package feature of vim, see :h packages).

NOTE: This plugin is only guaranteed to work with specific versions of language parsers (as specified in the lockfile.json). When upgrading the plugin, you must make sure that all installed parsers are updated to the latest version via :TSUpdate. It is strongly recommended to automate this; e.g., if you are using lazy.nvim, put this in your init.lua file:

1
2
3

require("lazy").setup({
  {"nvim-treesitter/nvim-treesitter", branch = 'master', lazy = false, build = ":TSUpdate"}
})

[!CAUTION]

This plugin does not support lazy-loading.

Make sure to specify the master branch, as the default branch will switch to main in the future.

For other plugin managers such as packer.nvim, see this Installation page from the wiki (Note that this page is community maintained).

Language parsers

Treesitter uses a different parser for every language, which needs to be generated via tree-sitter-cli from a grammar.js file, then compiled to a .so library that needs to be placed in neovim’s runtimepath (typically under parser/{language}.so). To simplify this, nvim-treesitter provides commands to automate this process. If the language is already supported by nvim-treesitter, you can install it with

`1`	`:TSInstall <language_to_install>`

This command supports tab expansion. You can also get a list of all available languages and their installation status with :TSInstallInfo. Parsers not on this list can be added manually by following the steps described under “Adding parsers” below.

To make sure a parser is at the latest compatible version (as specified in nvim-treesitter’s lockfile.json), use :TSUpdate {language}. To update all parsers unconditionally, use :TSUpdate all or just :TSUpdate.

Modules

Each module provides a distinct tree-sitter-based feature such as highlighting, indentation, or folding; see :h nvim-treesitter-modules or “Available modules” below for a list of modules and their options.

Following examples assume that you are configuring neovim with lua. If you are using vimscript, see :h lua-heredoc. All modules are disabled by default and need to be activated explicitly in your init.lua, e.g., via

require'nvim-treesitter.configs'.setup {
  -- A list of parser names, or "all" (the listed parsers MUST always be installed)
  ensure_installed = { "c", "lua", "vim", "vimdoc", "query", "markdown", "markdown_inline" },

  -- Install parsers synchronously (only applied to `ensure_installed`)
  sync_install = false,

  -- Automatically install missing parsers when entering buffer
  -- Recommendation: set to false if you don't have `tree-sitter` CLI installed locally
  auto_install = true,

  -- List of parsers to ignore installing (or "all")
  ignore_install = { "javascript" },

  ---- If you need to change the installation directory of the parsers (see -> Advanced Setup)
  -- parser_install_dir = "/some/path/to/store/parsers", -- Remember to run vim.opt.runtimepath:append("/some/path/to/store/parsers")!

  highlight = {
    enable = true,

    -- NOTE: these are the names of the parsers and not the filetype. (for example if you want to
    -- disable highlighting for the `tex` filetype, you need to include `latex` in this list as this is
    -- the name of the parser)
    -- list of language that will be disabled
    disable = { "c", "rust" },
    -- Or use a function for more flexibility, e.g. to disable slow treesitter highlight for large files
    disable = function(lang, buf)
        local max_filesize = 100 * 1024 -- 100 KB
        local ok, stats = pcall(vim.loop.fs_stat, vim.api.nvim_buf_get_name(buf))
        if ok and stats and stats.size > max_filesize then
            return true
        end
    end,

    -- Setting this to true will run `:h syntax` and tree-sitter at the same time.
    -- Set this to `true` if you depend on 'syntax' being enabled (like for indentation).
    -- Using this option may slow down your editor, and you may see some duplicate highlights.
    -- Instead of true it can also be a list of languages
    additional_vim_regex_highlighting = false,
  },
}

Each module can also be enabled or disabled interactively through the following commands:

:TSBufEnable {module} " enable module on current buffer
:TSBufDisable {module} " disable module on current buffer
:TSEnable {module} [{ft}] " enable module on every buffer. If filetype is specified, enable only for this filetype.
:TSDisable {module} [{ft}] " disable module on every buffer. If filetype is specified, disable only for this filetype.
:TSModuleInfo [{module}] " list information about modules state for each filetype

Check :h nvim-treesitter-commands for a list of all available commands. It may be necessary to reload the buffer (e.g., via :e) after enabling a module interactively.

Supported languages

For nvim-treesitter to support a specific feature for a specific language requires both a parser for that language and an appropriate language-specific query file for that feature.

The following is a list of languages for which a parser can be installed through :TSInstall; a checked box means that nvim-treesitter also contains queries at least for the highlight module.

Experimental parsers are parsers that have a maintainer but are not stable enough for daily use yet.

We are looking for maintainers to add more parsers and to write query files for their languages. Check our tracking issue for open language requests.

Available modules

Modules provide the top-level features of nvim-treesitter. The following is a list of modules included in nvim-treesitter and their configuration via init.lua (where multiple modules can be combined in a single call to setup). Note that not all modules work for all languages (depending on the queries available for them). Additional modules can be provided as external plugins.

Highlight

Consistent syntax highlighting.

require'nvim-treesitter.configs'.setup {
  highlight = {
    enable = true,
    -- Setting this to true will run `:h syntax` and tree-sitter at the same time.
    -- Set this to `true` if you depend on 'syntax' being enabled (like for indentation).
    -- Using this option may slow down your editor, and you may see some duplicate highlights.
    -- Instead of true it can also be a list of languages
    additional_vim_regex_highlighting = false,
  },
}

To customize the syntax highlighting of a capture, simply define or link a highlight group of the same name:

1
2

-- Highlight the @foo.bar capture group with the "Identifier" highlight group
vim.api.nvim_set_hl(0, "@foo.bar", { link = "Identifier" })

For a language-specific highlight, append the name of the language:

1
2

-- Highlight @foo.bar as "Identifier" only in Lua files
vim.api.nvim_set_hl(0, "@foo.bar.lua", { link = "Identifier" })

See :h treesitter-highlight-groups for details.

Incremental selection

Incremental selection based on the named nodes from the grammar.

require'nvim-treesitter.configs'.setup {
  incremental_selection = {
    enable = true,
    keymaps = {
      init_selection = "gnn", -- set to `false` to disable one of the mappings
      node_incremental = "grn",
      scope_incremental = "grc",
      node_decremental = "grm",
    },
  },
}

Indentation

Indentation based on treesitter for the = operator. NOTE: This is an experimental feature.

require'nvim-treesitter.configs'.setup {
  indent = {
    enable = true
  }
}

Folding

Tree-sitter based folding (implemented in Neovim itself, see :h vim.treesitter.foldexpr()). To enable it for the current window, set

1
2

vim.wo.foldmethod = 'expr'
vim.wo.foldexpr = 'v:lua.vim.treesitter.foldexpr()'

This will respect your foldminlines and foldnestmax settings.

Advanced setup

Changing the parser install directory

If you want to install the parsers to a custom directory you can specify this directory with parser_install_dir option in that is passed to setup. nvim-treesitter will then install the parser files into this directory.

This directory must be writeable and must be explicitly prepended to the runtimepath. For example:

  -- It MUST be at the beginning of runtimepath. Otherwise the parsers from Neovim itself
  -- is loaded that may not be compatible with the queries from the 'nvim-treesitter' plugin.
  vim.opt.runtimepath:prepend("/some/path/to/store/parsers")

  require'nvim-treesitter.configs'.setup {
    parser_install_dir = "/some/path/to/store/parsers",

    ...

  }

If this option is not included in the setup options, or is explicitly set to nil then the default install directories will be used. If this value is set the default directories will be ignored.

Bear in mind that any parser installed into a parser folder on the runtime path will still be considered installed. (For example if “~/.local/share/nvim/site/parser/c.so” exists then the “c” parser will be considered installed, even though it is not in parser_install_dir)

The default paths are:

first the package folder. Where nvim-treesitter is installed.
second the site directory. This is the “site” subdirectory of stdpath("data").

Adding parsers

If you have a parser that is not on the list of supported languages (either as a repository on Github or in a local directory), you can add it manually for use by nvim-treesitter as follows:

Clone the repository or create a new project in, say, ~/projects/tree-sitter-zimbu. Make sure that the tree-sitter-cli executable is installed and in your path; see https://tree-sitter.github.io/tree-sitter/creating-parsers#installation for installation instructions.
Run tree-sitter generate in this directory (followed by tree-sitter test for good measure).
Add the following snippet to your init.lua:

local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
parser_config.zimbu = {
  install_info = {
    url = "~/projects/tree-sitter-zimbu", -- local path or git repo
    files = {"src/parser.c"}, -- note that some parsers also require src/scanner.c or src/scanner.cc
    -- optional entries:
    branch = "main", -- default branch in case of git repo if different from master
    generate_requires_npm = false, -- if stand-alone parser without npm dependencies
    requires_generate_from_grammar = false, -- if folder contains pre-generated src/parser.c
  },
  filetype = "zu", -- if filetype does not match the parser name
}

If you wish to set a specific parser for a filetype, you should use vim.treesitter.language.register():

`1`	`vim.treesitter.language.register('python', 'someft') -- the someft filetype will use the python parser and queries.`

Note this requires Nvim v0.9.

Start nvim and :TSInstall zimbu.

You can also skip step 2 and use :TSInstallFromGrammar zimbu to install directly from a grammar.js in the top-level directory specified by url. Once the parser is installed, you can update it (from the latest revision of the main branch if url is a Github repository) with :TSUpdate zimbu.

Note that neither :TSInstall nor :TSInstallFromGrammar copy query files from the grammar repository. If you want your installed grammar to be useful, you must manually add query files to your local nvim-treesitter installation. Note also that module functionality is only triggered if your language’s filetype is correctly identified. If Neovim does not detect your language’s filetype by default, you can use Neovim’s vim.filetype.add() to add a custom detection rule.

If you use a git repository for your parser and want to use a specific version, you can set the revision key in the install_info table for you parser config.

Adding queries

Queries are what nvim-treesitter uses to extract information from the syntax tree; they are located in the queries/{language}/* runtime directories (see :h rtp), like the queries folder of this plugin, e.g. queries/{language}/{locals,highlights,textobjects}.scm. Other modules may require additional queries such as folding.scm. You can find a list of all supported capture names in CONTRIBUTING.md.

The first query file on runtimepath will be used (see :h treesitter-query). If you want to make a query on the user config extend other queries instead of replacing them, see :h treesitter-query-modeline-extends.

If you want to completely override a query, you can use :h vim.treesitter.query.set(). For example, to override the injections queries from c with your own:

`1`	`vim.treesitter.query.set("c", "injections", "(comment) @comment")`

Note: when using query.set(), all queries in the runtime directories will be ignored.

Adding modules

If you wish you write your own module, you need to support

tree-sitter language detection support;
attaching and detaching to buffers;
all nvim-treesitter commands.

At the top level, you can use the define_modules function to define one or more modules or module groups:

require'nvim-treesitter'.define_modules {
  my_cool_plugin = {
    attach = function(bufnr, lang)
      -- Do cool stuff here
    end,
    detach = function(bufnr)
      -- Undo cool stuff here
    end,
    is_supported = function(lang)
      -- Check if the language is supported
    end
  }
}

with the following properties:

module_path specifies a require path (string) that exports a module with an attach and detach function. This is not required if the functions are on this definition.
enable determines if the module is enabled by default. This is usually overridden by the user.
disable takes a list of languages that this module is disabled for. This is usually overridden by the user.
is_supported takes a function that takes a language and determines if this module supports that language.
attach takes a function that attaches to a buffer. This is required if module_path is not provided.
detach takes a function that detaches from a buffer. This is required if module_path is not provided.

Utilities

You can get some utility functions with

`1`	`local ts_utils = require 'nvim-treesitter.ts_utils'`

Check :h nvim-treesitter-utils for more information.

Troubleshooting

Before doing anything, make sure you have the latest version of this plugin and run :checkhealth nvim-treesitter. It can also help to update the parsers via :TSUpdate.

Feature `X` does not work for `{language}`…

First, check the health#nvim_treesitter#check and the health#treesitter#check sections of :checkhealth for any warning. If there is one, it’s highly likely that this is the cause of the problem.

Next check the ## Parser/Features subsection of the health#nvim_treesitter#check section of :checkhealth to ensure the desired module is enabled for your language. If not, you might be missing query files; see Adding queries.

Finally, ensure Neovim is correctly identifying your language’s filetype using the :echo &filetype command while one of your language’s files is open in Neovim. If not, add a short Vimscript file to nvim-treesitter’s ftdetect runtime directory following Neovim’s documentation on filetype detection. You can also quickly & temporarily set the filetype for a single buffer with the :set filetype=langname command to test whether it fixes the problem.

If everything is okay, then it might be an actual error. In that case, feel free to open an issue here.

I get `module 'vim.treesitter.query' not found`

Make sure you have the latest version of Neovim.

I get `Error detected while processing .../plugin/nvim-treesitter.vim` every time I open Neovim

This is probably due to a change in a parser’s grammar or its queries. Try updating the parser that you suspect has changed (:TSUpdate {language}) or all of them (:TSUpdate). If the error persists after updating all parsers, please open an issue.

I get `query error: invalid node type at position`

This could be due a query file outside this plugin using outdated nodes, or due to an outdated parser.

Make sure you have the parsers up to date with :TSUpdate
Make sure you don’t have more than one parser runtime directory. You can execute this command :echo nvim_get_runtime_file('parser', v:true) to find all runtime directories. If you get more than one path, remove the ones that are outside this plugin (nvim-treesitter directory), so the correct version of the parser is used.

I experience weird highlighting issues similar to #78

This is a well known issue, which arises when the tree and the buffer have gotten out of sync. As this is an upstream issue, we don’t have any definite fix. To get around this, you can force reparsing the buffer with

`1`	`:write \| edit \| TSBufEnable highlight`

This will save, restore and enable highlighting for the current buffer.

I experience bugs when using `nvim-treesitter`’s `foldexpr` similar to #194

This might happen, and is known to happen, with vim-clap. To avoid these kind of errors, please use setlocal instead of set for the respective filetypes.

I run into errors like `module 'nvim-treesitter.configs' not found` at startup

This is because of rtp management in nvim, adding packadd nvim-treesitter should fix the issue.

I want to use Git instead of curl for downloading the parsers

In your Lua config:

`1`	`require("nvim-treesitter.install").prefer_git = true`

I want to use a HTTP proxy for downloading the parsers

You can either configure curl to use additional CLI arguments in your Lua config:

1
2
3

require("nvim-treesitter.install").command_extra_args = {
    curl = { "--proxy", "<proxy url>" },
}

or you can configure git via .gitconfig and use git instead of curl

`1`	`require("nvim-treesitter.install").prefer_git = true`

I want to use a mirror instead of “https://github.com/"

In your Lua config:

for _, config in pairs(require("nvim-treesitter.parsers").get_parser_configs()) do
  config.install_info.url = config.install_info.url:gsub("https://github.com/", "something else")
end

require'nvim-treesitter.configs'.setup {
    --
    --
}

Using an existing parser for another filetype

For example, to use the bash tree-sitter to highlight file with filetype=apkbuild, use:

`1`	`vim.treesitter.language.register("bash", "apkbuild")`

The bash tree-sitter must be installed following the usual procedure as described above.
