# Contributing to `nvim-treesitter`
The main parts of `nvim-treesitter` are
* a curated list of [parsers](#Parsers);
* a collection of [queries](#Queries).
First of all, thank you very much for contributing to `nvim-treesitter`.
Before describing these in detail, some general advice:
* Some basic knowledge of how tree-sitter works is assumed; we recommend reading
- the [upstream documentation](https://tree-sitter.github.io/tree-sitter/);
- [Neovim's documentation](https://neovim.io/doc/user/treesitter.html#treesitter).
* There are dedicated Matrix channels for questions and general help:
- [#nvim-treesitter](https://matrix.to/#/#nvim-treesitter:matrix.org) for questions specific to Neovim's implementation and the queries here;
- [#tree-sitter](https://matrix.to/#/#tree-sitter-chat:matrix.org) for general questions regarding treesitter queries and the `tree-sitter` CLI.
If you haven't already, you should really come and reach out to us on our
[Matrix channel], so we can help you with any question you might have!
## Parsers
As you know, `nvim-treesitter` is roughly split in two parts:
>[!IMPORTANT]
> To qualify for inclusion, a parser must meet the following criteria:
> * correspond to a filetype detected by Neovim (nightly)
> * feature complete, tested by users, and actively maintained (according to maintainer discretion)
> * hosted or mirrored on Github (other codeforges are not reliable enough for CI)
> * covered by CI using [upstream workflows](https://github.com/tree-sitter/workflows)
> * provide reference queries covered by a [`ts_query_ls` workflow](https://github.com/tree-sitter-grammars/template/blob/9c46d09d688d27c7aef31c2b32f50260de4e7906/.github/workflows/ci.yml#L69-L86)
> * if the repo contains a `src/parser.c`, it must support the latest ABI
> * if the repo does _not_ contain a `src/parser.c`, it must contain an up-to-date `src/grammar.json`
> * if the repo contains an external scanner, it must be written in C99
>
> Tier 1 parsers (preferred) in addition need to
> * make regular releases following semver (_patch_ for fixes not affecting queries; _minor_ for changes introducing new nodes or patterns; _major_ for changes removing nodes or previously valid patterns)
> * provide WASM release artifacts
- Parser configurations : for various things like `locals`, `highlights`
- What we like to call _modules_ : tiny lua modules that provide a given feature, based on parser configurations
To add a new parser, edit the following files:
Depending on which part of the plugin you want to contribute to, please read the appropriate section.
1. In `lua/parsers.lua`, add an entry to the returned table of the following form:
## Style Checks and Tests
```lua
zimbu = {
install_info = {
url = 'https://github.com/zimbulang/tree-sitter-zimbu', -- git repo; use `path` for local path
revision = 'v2.1', -- tag or commit hash
-- optional entries:
branch = 'develop', -- only needed if different from default branch
location = 'parser', -- only needed if the parser is in subdirectory of a "monorepo"
generate = true, -- only needed if repo does not contain pre-generated src/parser.c
},
maintainers = { '@me' }, -- the _query_ maintainers
tier = 1, -- stable: track versioned releases instead of latest commit
-- optional entries:
requires = { 'vim' }, -- if the queries inherit from another language
readme_note = "an example language",
}
We haven't implemented any functional tests yet. Feel free to contribute.
However, we check code style with `luacheck` and `stylua`!
Please install luacheck and activate our `pre-push` hook to automatically check style before
every push:
```bash
luarocks install luacheck
cargo install stylua
ln -s ../../scripts/pre-push .git/hooks/pre-push
```
>[!IMPORTANT]
> The "maintainers" here refers to the person maintaining the **queries** in `nvim-treesitter`, not the parser maintainers (who likely don't use Neovim). The maintainers' duty is to review issues and PRs related to the query and to keep them updated with respect to parser changes.
## Adding new modules
2. If the parser name is not the same as the Vim filetype, add an entry to the `filetypes` table in `plugin/filetypes.lua`:
If you want to see a new functionality added to `nvim-treesitter` feel free to first open an issue
to that we can track our solution!
Thus far, there is basically two types of modules:
```lua
zimbu = { 'zu' },
```
- Little modules (like `incremental selection`) that are built in `nvim-treesitter`, we call them
`builtin modules`.
- Bigger modules (like `completion-treesitter`, or `nvim-tree-docs`), or modules that integrate
with other plugins, that we call `remote modules`.
3. Update the list of [supported languages] by running `make docs` (or `./scripts/update-readme.lua` if on Windows).
In any case, you can build your own module! To help you started in the process, we have a template
repository designed to build new modules [here](https://github.com/nvim-treesitter/module-template).
Feel free to use it, and contact us over on our
on the "Neovim tree-sitter" [Matrix channel].
4. Test if both `:TSInstall zimbu` and `:TSInstallFromGrammar zimbu` work without errors (`:checkhealth treesitter` or `./scripts/check-parsers.lua zimbu`).
## Parser configurations
>[!IMPORTANT]
> You also need to add queries in order for the parser to actually be useful!
Contributing to parser configurations is basically modifying one of the `queries/*/*.scm`.
Each of these `scheme` files contains a _tree-sitter query_ for a given purpose.
Before going any further, we highly suggest that you [read more about tree-sitter queries](https://tree-sitter.github.io/tree-sitter/using-parsers#pattern-matching-with-queries).
When you're done, open a Pull Request using the [provided template](.github/PULL_REQUEST_TEMPLATE/new_language.md), e.g. using `gh pr create -B main -T new_language`.
Each query has an appropriate name, which is then used by modules to extract data from the syntax tree.
For now these are the types of queries used by `nvim-treesitter`:
## Queries
- `highlights.scm`: used for syntax highlighting, using the `highlight` module.
- `locals.scm`: used to extract keyword definitions, scopes, references, etc, using the `locals` module.
- `textobjects.scm`: used to define text objects.
- `folds.scm`: used to define folds.
- `injections.scm`: used to define injections.
To add (or edit existing) queries, create a corresponding `runtime/queries/zimbu/*.scm` file:
For these types there is a _norm_ you will have to follow so that features work fine.
Here are some global advices:
- `highlights.scm` used for syntax highlighting,
- `injections.scm` used to specify nodes whose content should be parsed as a different language;
- `folds.scm`; used to define folds;
- `locals.scm`: used to extract keyword definitions, scopes, references, etc. (not used in this plugin).
- `indents.scm`; used to control indentation.
See [tree-sitter queries] for a basic description of the query language. The following tools can be helpful when writing or editing queries:
* [ts_query_ls] is a language server for treesitter queries, which can validate, autocomplete, and format. This tool can also be used as an offline linter and formatter (accessible through `make lintquery`, `make checkquery`, `make formatquery` targets).
* Neovim's `:InspectTree` will show the parsed tree for a buffer and highlight the text corresponding to any given node (and vice versa).
* `:EditQuery` opens a "playground" where you can write query patterns and see which parts of the buffer are captured by each capture.
>[!IMPORTANT]
> The valid captures that can be used in queries is different for each editor, so you cannot just copy them, e.g., from Helix or the parser repositories. For Neovim, all valid captures are listed below. You can verify that your changes adhere to this by running `make lintquery`.
>[!IMPORTANT]
> Since grammars can change constantly, it is important to make sure that the patterns in a query are actually valid for the parser specified in nvim-treesitter's manifest. This can be verified using `make checkquery` (which requires the parser to be installed in the default directory(!) through `nvim-treesitter`). Opening the query in Neovim with the parser installed will also show all invalid patterns, either via [ts_query_ls] or Neovim's builtin query-linter.
>[!TIP]
> Before opening a PR, run `make query` to format, lint, and check all queries.
#### Inheriting languages
- If your language is listed [here](https://github.com/nvim-treesitter/nvim-treesitter#supported-languages),
you can install the [playground plugin](https://github.com/nvim-treesitter/playground).
- If your language is listed [here](https://github.com/nvim-treesitter/nvim-treesitter#supported-languages),
you can debug and experiment with your queries there.
- If not, you should consider installing the [tree-sitter cli](https://github.com/tree-sitter/tree-sitter/tree/master/cli),
you should then be able to open a local playground using `tree-sitter build-wasm && tree-sitter web-ui` within the
parsers repo.
- Examples of queries can be found in [queries/](queries/)
- Matches in the bottom will override queries that are above of them.
If your language is an extension of a language (TypeScript is an extension of JavaScript for
example), you can include the queries from your base language by adding the following _as the first
line of your file_:
line of your file_.
```query
; inherits: lang1,(optionallang)
@ -106,405 +80,205 @@ line of your file_:
If you want to inherit a language, but don't want the languages inheriting from yours to inherit it,
you can mark the language as optional (by putting it between parenthesis).
#### Formatting
All queries are expected to follow a standard format, with every node on a single line and indented by two spaces for each level of nesting. You can automatically format the bundled queries by running `make formatquery`.
Should you need to preserve a specific format for a node, you can exempt it (and all contained nodes) by placing before it
```query
; format-ignore
```
### Highlights
Syntax highlighting is specified in a `highlights.scm` query, which assigns treesitter nodes to captures that can be assigned a highlight group. This feature is implemented in Neovim and documented at [`:h treesitter-highlight`](https://neovim.io/doc/user/treesitter.html#treesitter-highlight).
Note that your color scheme needs to define (or link) these captures as highlight groups. You can use Neovim's built-in `:Inspect` function to see exactly which highlight groups are applied at a given position.
As languages differ quite a lot, here is a set of captures available to you when building a `highlights.scm` query. Note that your colorscheme needs to define (or link) these captures as highlight groups.
The valid captures are listed below.

#### Conceal
```scheme
@conceal ; for captures that are only used for concealing
```
#### Non-highlighting captures
`@conceal` must be followed by `(#set! conceal "")`.
```query
@conceal ; captures that are only meant to be concealed
```
#### Spell
>[!TIP]
> * See [`:h tree-sitter-highlight-conceal`](https://neovim.io/doc/user/treesitter.html#treesitter-highlight-conceal).
> * The capture should be meaningful to allow proper highlighting when `set conceallevel=0`.
> * A conceal can be restricted to part of the capture via the [`#offset!` directive](https://neovim.io/doc/user/treesitter.html#treesitter-directive-offset%21).
```query
```scheme
@spell ; for defining regions to be spellchecked
@nospell ; for defining regions that should NOT be spellchecked
```
>[!TIP]
> The main types of nodes that should be spell checked are
> - comments
> - strings; where it makes sense. Strings that have interpolation or are typically used for non text purposes are not spell checked (e.g. bash).
#### Predicates
Captures can be restricted according to node contents using [predicates](https://neovim.io/doc/user/treesitter.html#treesitter-predicates).
>[!IMPORTANT]
> For performance reasons, prefer earlier predicates in this list:
>
> 1. `#eq?` (literal match)
> 2. `#any-of?` (one of several literal matches)
> 3. `#lua-match?` (match against a [Lua pattern](https://neovim.io/doc/user/luaref.html#lua-pattern))
> 4. `#match?`/`#vim-match?` (match against a [Vim regular expression](https://neovim.io/doc/user/pattern.html#regexp)
Besides those provided by Neovim, nvim-treesitter also implements
```query
#kind-eq? ; checks whether a capture corresponds to a given set of nodes
#any-kind-eq? ; checks whether any of a list of captures corresponds to a given set of nodes
```
#### Directives
Nodes contain metadata that can be modified via [directives](https://neovim.io/doc/user/treesitter.html#treesitter-directives).
The main types of nodes which are spell checked are:
- Comments
- Strings; where it makes sense. Strings that have interpolation or are typically used for non text purposes are not spell checked (e.g. bash).
#### Priority
Captures can be assigned a priority to control precedence of highlights via the
`#set! priority <number>` directive (see [`:h treesitter-highlight-priority`](https://neovim.io/doc/user/treesitter.html#treesitter-highlight-priority)). This is useful for controlling conflicts with injected languages or when inheriting queries from other languages.
>[!NOTE]
> The default priority for treesitter highlights is `100`; queries should only
set priorities between `90` and `120`, to avoid conflict with other sources of highlighting (such as diagnostics or LSP semantic tokens).
>[!TIP]
> Precedence is also influenced by pattern order in a query file. If possible, try to achieve the correct result by reordering patterns before resorting to explicit priorities.
### Injections
Language injections are controlled by `injections.scm` queries, which specify nodes that should be parsed as a different language. This feature is implemented in Neovim and documented at
[`:h treesitter-language-injections](https://neovim.io/doc/user/treesitter.html#treesitter-language-injections).
The valid captures are:
```query
@injection.language ; dynamic detection of the injection language (i.e. the text of the captured node describes the language)
@injection.content ; region for the dynamically detected language
@injection.filename ; indicates that the captured node’s text may contain a filename; the corresponding filetype is then looked-up up via vim.filetype.match() and treated as the name of a language that should be used to re-parse the `@injection.content`
```
>[!TIP]
> When writing injection queries, try to ensure that each captured node is only matched by a single pattern.
### Folds
You can define folds for a given language by adding a `folds.scm` query. This is implemented in Neovim. The only valid capture is `@fold`:
```query
(function_definition) @fold ; fold this node
```
Folds should be given to nodes with defined start and end delimiters/patterns, or to consecutive nodes which are part of the same conceptual "grouping", such as consecutive line comments or import statements. The following items are valid fold candidates:
- Function/method definitions
- Class/interface/trait definitions
- Switch/match statements, and individual match arms
- Execution blocks (such as those found in conditional statements or loops)
- Parameter/argument lists
- Array/object/string expressions
- Consecutive import statements, consecutive line comments
The following items would *not* be valid fold candidates:
- Multiline assignment statements
- Multiline property access expressions
As a rule of thumb, these highlight captures usually reside in or around objects which should be folded:
- `@function`, `@function.method`
- `@keyword.import`, `@keyword.conditional`, `@keyword.repeat`
- `@comment`, `@comment.documentation`
- `@string`, `@string.documentation`
- `@markup.heading.x`, `@markup.list`
### Indents
>[!WARNING]
> Treesitter-based indentation is still experimental and likely to have breaking changes in the future.
Indentation for a language is controlled by `indents.scm` queries. The following captures can be used to set the indentation for nodes, either relative or absolute
* `@indent.begin` specifies that the next line should be indented. Multiple
indents on the same line get collapsed, e.g.,
```query
(
(if_statement)
(ERROR "else") @indent.begin
)
```
You can also `#set! indent.immediate` to permit the next line to indent even when the block intended to be indented has no content yet. (This can improve interactive typing.)
For example for Python,
```query
((if_statement) @indent.begin
(#set! indent.immediate 1))
```
will allow
```python
if True:<CR>
# Auto indent to here
```
* `@indent.end` is used to specify that the indented region ends and any text subsequent to the capture should be dedented.
* `@indent.branch` is used to specify that a dedented region starts at the line _including_ the captured nodes.
* `@indent.dedent` specifies dedenting starting on the _next_ line.
* `@indent.auto` behaves like Vim's [`autoindent`](https://neovim.io/doc/user/options.html#'autoindent') buffer option (copy whatever the indentation of previous line is when opening a new line after it).
* `@indent.ignore` specifies that no indent should be added to this node.
* `@indent.zero` sets the indentation of this node to 0 (i.e., removes _all_ indentation).
* `@indent.align` can be used to specify blocks that should have the same indentation.
This allows
```
foo(a,
b,
c)
```
as well as
```
foo(
a,
b,
c)
```
and
```
foo(
a,
b,
c
)
```
To specify the delimiters to align at, `#set! indent.open_delimiter` and
`indent.close_delimiter`, e.g.,
```query
((argument_list) @indent.align
(#set! indent.open_delimiter "(")
(#set! indent.close_delimiter ")"))
```
For some languages, the last line of an `indent.align` block must not be
the same indent as the natural next line.
For example in Python,
```python
if (a > b and
c < d):
pass
```
is not correct, whereas
```python
if (a > b and
c < d):
pass
```
would be correctly indented. This behavior may be selected by setting
`indent.avoid_last_matching_next`. For example,
```query
(if_statement
condition: (parenthesized_expression) @indent.align
(#set! indent.open_delimiter "(")
(#set! indent.close_delimiter ")")
(#set! indent.avoid_last_matching_next 1)
)
```
specifies that the last line of an `@indent.align` capture
should be additionally indented to avoid clashing with the indent of the first
line of the block inside an `if`.
`#set! "priority" <number>` directive (see `:h treesitter-highlight-priority`).
The default priority for treesitter highlights is `100`; queries should only
set priorities between `90` and `120`, to avoid conflict with other sources of
highlighting (such as diagnostics or LSP semantic tokens).
### Locals
Locals are used to keep track of definitions and references in local or global
scopes, see [upstream
documentation](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#local-variables).
Note that nvim-treesitter uses more specific subcaptures for definitions and
**does not use locals** (for highlighting or any other purpose). These queries
are only provided for limited backwards compatibility.
Note: pay specific attention to the captures here as they are a bit different to
those listed in the upstream [Local Variables
docs](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#local-variables).
Some of these docs didn't exist when `nvim-treesitter` was created and the
upstream captures are more limiting than what we have here.

### Folds
[supported languages]: https://github.com/nvim-treesitter/nvim-treesitter/SUPPORTED_LANGUAGES.md
[tree-sitter queries]: https://tree-sitter.github.io/tree-sitter/using-parsers/queries/index.html
[ts_query_ls]: https://github.com/ribru17/ts_query_ls
You can define folds for a given language by adding a `folds.scm` query :
```scheme
@fold ; fold this node
```
If the `folds.scm` query is not present, this will fall back to the `@scope` captures in the `locals`
query.
### Injections
Some captures are related to language injection (like markdown code blocks). They are used in `injections.scm`.
You can directly use the name of the language that you want to inject (e.g. `@html` to inject html).
If you want to dynamically detect the language (e.g. for Markdown blocks) use the `@language` to capture
the node describing the language and `@content` to describe the injection region.
```scheme
@{lang} ; e.g. @html to describe a html region
@language ; dynamic detection of the injection language (i.e. the text of the captured node describes the language)
@content ; region for the dynamically detected language
@combined ; combine all matches of a pattern as one single block of content
```
### Indents
```scheme
@indent.begin ; indent children when matching this node
@indent.end ; marks the end of indented block
@indent.align ; behaves like python aligned/hanging indent
@indent.dedent ; dedent children when matching this node
@indent.branch ; dedent itself when matching this node
@indent.ignore ; do not indent in this node
@indent.auto ; behaves like 'autoindent' buffer option
@indent.zero ; sets this node at position 0 (no indent)

The `nvim-treesitter` plugin provides
1. functions for installing, updating, and removing [**tree-sitter parsers**](SUPPORTED_LANGUAGES.md);
2. a collection of **queries** for enabling tree-sitter features built into Neovim for these languages;
3. a staging ground for [treesitter-based features](#Supported-features) considered for upstreaming to Neovim.

For details on these and how to help improving them, see [CONTRIBUTING.md](./CONTRIBUTING.md).
The goal of `nvim-treesitter` is both to provide a simple and easy way to use the interface for [tree-sitter](https://github.com/tree-sitter/tree-sitter) in Neovim and to provide some basic functionality such as highlighting based on it:
>[!CAUTION]
> This is a full, incompatible, rewrite: Treat this as a different plugin you need to set up from scratch following the instructions below. If you can't or don't want to update, specify the [`master` branch](https://github.com/nvim-treesitter/nvim-treesitter/blob/master/README.md) (which is locked but will remain available for backward compatibility with Nvim 0.11).
![example-cpp](https://user-images.githubusercontent.com/2361214/202753610-e923bf4e-e88f-494b-bb1e-d22a7688446f.png)
Traditional highlighting (left) vs Treesitter-based highlighting (right).
More examples can be found in [our gallery](https://github.com/nvim-treesitter/nvim-treesitter/wiki/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](https://github.com/nvim-treesitter/nvim-treesitter/projects/1).
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**](#language-parsers), [**queries**](#adding-queries), and [**modules**](#available-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"](#advanced-setup).

# Quickstart
## Requirements
- Neovim 0.12.0 or later (nightly)
- `tar` and `curl` in your path
- [`tree-sitter-cli`](https://github.com/tree-sitter/tree-sitter/blob/master/crates/cli/README.md) (0.26.1 or later, installed via your package manager, **not npm**)
- a C compiler in your path (see <https://docs.rs/cc/latest/cc/#compile-time-requirements>)
>[!IMPORTANT]
> The current **support policy** for Neovim is
> * the _latest_ [stable release](https://github.com/neovim/neovim/releases/tag/stable),
> * the _latest_ [nightly prerelease](https://github.com/neovim/neovim/releases/tag/nightly).
> Other versions may work but are neither tested nor considered for fixes.
- [Latest](https://github.com/neovim/neovim/releases/tag/stable) Neovim release ([nightly](https://github.com/neovim/neovim#install-from-source) recommended)
- `tar` and `curl` in your path (or alternatively `git`)
- A C compiler in your path and libstdc++ installed ([Windows users please read this!](https://github.com/nvim-treesitter/nvim-treesitter/wiki/Windows-support)).
## Installation
You can install `nvim-treesitter` with your favorite package manager (or using the native `package` feature of vim, see `:h packages`).
This plugin is only guaranteed to work with specific versions of language parsers** (as specified in the `parser.lua` table). **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., using the following spec with [lazy.nvim](https://github.com/folke/lazy.nvim):
**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 [vim-plug](https://github.com/junegunn/vim-plug), put this in your `init.vim` file:
```vim
Plug 'nvim-treesitter/nvim-treesitter', {'do': ':TSUpdate'}
```
For other plugin managers such as `packer.nvim`, see this [Installation page from the wiki](https://github.com/nvim-treesitter/nvim-treesitter/wiki/Installation) (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`](#supported-languages), you can install it with
```vim
: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"](#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](#highlight), [indentation](#indentation), or [folding](#folding); see [`:h nvim-treesitter-modules`](doc/nvim-treesitter.txt) or ["Available modules"](#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
```lua
{
'nvim-treesitter/nvim-treesitter',
lazy = false,
build = ':TSUpdate'
require'nvim-treesitter.configs'.setup {
-- A list of parser names, or "all" (the five listed parsers should always be installed)
ensure_installed = { "c", "lua", "vim", "vimdoc", "query" },
-- 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 (for "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,
},
}
```
>[!IMPORTANT]
> This plugin does not support lazy-loading.
Each module can also be enabled or disabled interactively through the following commands:
## Setup
`nvim-treesitter` can be configured by calling `setup`. **You do not need to call `setup` for `nvim-treesitter` to work using default values.**
```lua
require('nvim-treesitter').setup {
-- Directory to install parsers and queries to (prepended to `runtimepath` to have priority)
install_dir = vim.fn.stdpath('data') .. '/site'
}
```
Parsers and queries can then be installed with
```lua
require('nvim-treesitter').install { 'rust', 'javascript', 'zig' }
```
(This is a no-op if the parsers are already installed.) Note that this function runs asynchronously; for synchronous installation in a script context ("bootstrapping"), you need to `wait()` for it to finish:
```lua
require('nvim-treesitter').install({ 'rust', 'javascript', 'zig' }):wait(300000) -- wait max. 5 minutes
```vim
: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`](doc/nvim-treesitter.txt) 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.
A list of the currently supported languages can be found [on this page](SUPPORTED_LANGUAGES.md). If you wish to add a new language or improve the queries for an existing one, please see our [contributing guide](CONTRIBUTING.md).
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.
# Supported features
Experimental parsers are parsers that have a maintainer but are not stable enough for
daily use yet.
`nvim-treesitter` provides queries for the following features. **These are not automatically enabled.**
We are looking for maintainers to add more parsers and to write query files for their languages. Check our [tracking issue](https://github.com/nvim-treesitter/nvim-treesitter/issues/2282) for open language requests.

<!--parserinfo-->
Treesitter highlighting is provided by Neovim, see `:h treesitter-highlight`. To enable it for a filetype, put `vim.treesitter.start()` in a `ftplugin/<filetype>.lua` in your config directory, or place the following in your `init.lua`:
For related information on the supported languages, including related plugins, see [this wiki page](https://github.com/nvim-treesitter/nvim-treesitter/wiki/Supported-Languages-Information).
# 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](https://github.com/nvim-treesitter/nvim-treesitter/wiki/Extra-modules-and-plugins).
#### Highlight
Consistent syntax highlighting.
```lua
vim.api.nvim_create_autocmd('FileType', {
pattern = { '<filetype>' },
callback = function() vim.treesitter.start() end,
})
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,
},
}
```
## Folds
Treesitter-based folding is provided by Neovim. To enable it, put the following in your `ftplugin` or `FileType` autocommand:
To customize the syntax highlighting of a capture, simply define or link a highlight group of the same name:
```lua
vim.wo[0][0].foldexpr = 'v:lua.vim.treesitter.foldexpr()'
vim.wo[0][0].foldmethod = 'expr'
-- Highlight the @foo.bar capture group with the "Identifier" highlight group
vim.api.nvim_set_hl(0, "@foo.bar", { link = "Identifier" })
```
## Indentation
Treesitter-based indentation is provided by this plugin but considered **experimental**. To enable it, put the following in your `ftplugin` or `FileType` autocommand:
For a language-specific highlight, append the name of the language:
```lua
vim.bo.indentexpr = "v:lua.require'nvim-treesitter'.indentexpr()"
-- Highlight @foo.bar as "Identifier" only in Lua files
vim.api.nvim_set_hl(0, "@foo.bar.lua", { link = "Identifier" })
```
(Note the specific quotes used.)
See `:h treesitter-highlight-groups` for details.
## Injections
#### Incremental selection
Injections are used for multi-language documents, see `:h treesitter-language-injections`. No setup is needed.
Incremental selection based on the named nodes from the grammar.
## Locals
```lua
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",
},
},
}
```
These queries can be used to look up definitions and references to identifiers in a given scope. They are not used in this plugin and are provided for (limited) backward compatibility.
#### Indentation
Indentation based on treesitter for the `=` operator.
**NOTE: This is an experimental feature**.
```lua
require'nvim-treesitter.configs'.setup {
indent = {
enable = true
}
}
```
#### Folding
Tree-sitter based folding. _(Technically not a module because it's per windows and not per buffer.)_
```vim
set foldmethod=expr
set foldexpr=nvim_treesitter#foldexpr()
set nofoldenable " Disable folding at startup.
```
This will respect your `foldminlines` and `foldnestmax` settings.
# Advanced setup
## Adding custom languages
## 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 added to the
`runtimepath`. For example:
```lua
vim.opt.runtimepath:append("/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:
1. first the package folder. Where `nvim-treesitter` is installed.
2. 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:
1. Add the following snippet in a `User TSUpdate` autocommand:
1. Clone the repository or [create a new project](https://tree-sitter.github.io/tree-sitter/creating-parsers#project-setup) 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.
2. Run `tree-sitter generate` in this directory (followed by `tree-sitter test` for good measure).
3. Add the following snippet to your `init.lua`:
```lua
vim.api.nvim_create_autocmd('User', { pattern = 'TSUpdate',
callback = function()
require('nvim-treesitter.parsers').zimbu = {
install_info = {
url = 'https://github.com/zimbulang/tree-sitter-zimbu',
revision = <sha>, -- commit hash for revision to check out; HEAD if missing
-- optional entries:
branch = 'develop', -- only needed if different from default branch
location = 'parser', -- only needed if the parser is in subdirectory of a "monorepo"
generate = true, -- only needed if repo does not contain pre-generated `src/parser.c`
generate_from_json = false, -- only needed if repo does not contain `src/grammar.json` either
queries = 'queries/neovim', -- also install queries from given directory
},
}
end})
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
}
```
Alternatively, if you have a local checkout, you can instead use
If you wish to set a specific parser for a filetype, you should use `vim.treesitter.language.register()`:
```lua
install_info = {
path = '~/parsers/tree-sitter-zimbu',
-- optional entries
location = 'parser',
generate = true,
generate_from_json = false,
queries = 'queries/neovim', -- symlink queries from given directory
},
```
This will always use the state of the directory as-is (i.e., `branch` and `revision` will be ignored).
2. If the parser name differs from the filetype(s) used by Neovim, you need to register the parser via
```lua
vim.treesitter.language.register('zimbu', { 'zu' })
vim.treesitter.language.register('python', 'someft') -- the someft filetype will use the python parser and queries.
```
Note this requires Nvim v0.9.
4. 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](#adding-queries) 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()`](<https://neovim.io/doc/user/lua.html#vim.filetype.add()>) to add a custom detection rule.
3. Start `nvim` and `:TSInstall zimbu`.
>[!IMPORTANT]
> If the parser requires an external scanner, this must be written in C.
### Modifying parsers
You can use the same approach for overriding parser information. E.g., if you always want to generate the `lua` parser from grammar, add
```lua
vim.api.nvim_create_autocmd('User', { pattern = 'TSUpdate',
callback = function()
require('nvim-treesitter.parsers').lua.install_info.generate = true
end})
```
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 can be placed anywhere in your `runtimepath` under `queries/<language>`, with earlier directories taking precedence unless the queries are marked with `; extends`; see [`:h treesitter-query-modelines`](https://neovim.io/doc/user/treesitter.html#treesitter-query-modeline).
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](https://github.com/nvim-treesitter/nvim-treesitter/blob/master/CONTRIBUTING.md#parser-configurations).
All queries found in the runtime directories will be combined.
By convention, if you want to write a query, use the `queries/` directory,
but if you want to extend a query use the `after/queries/` directory.
If you want to completely override a query, you can use `:h set_query()`.
For example, to override the `injections` queries from `c` with your own:
```lua
require("vim.treesitter.query").set_query("c", "injections", "(comment) @comment")
```
Note: when using `set_query`, 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:
```lua
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.
# Extra features
### Statusline indicator
```vim
echo nvim_treesitter#statusline(90) " 90 can be any length
module->expression_statement->call->identifier
```
### Utilities
You can get some utility functions with
```lua
local ts_utils = require 'nvim-treesitter.ts_utils'
```
Check [`:h nvim-treesitter-utils`](doc/nvim-treesitter.txt) 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](#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](https://neovim.io/doc/user/filetype.html#new-filetype) 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](https://github.com/nvim-treesitter/nvim-treesitter/issues/new/choose).
#### 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](https://github.com/nvim-treesitter/nvim-treesitter/issues/new/choose).
#### 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](https://github.com/nvim-treesitter/nvim-treesitter/issues/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
```vim
: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](https://github.com/nvim-treesitter/nvim-treesitter/issues/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:
```lua
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:
```lua
require("nvim-treesitter.install").command_extra_args = {
curl = { "--proxy", "<proxy url>" },
}
```
or you can configure git via `.gitconfig` and use git instead of curl
```lua
require("nvim-treesitter.install").prefer_git = true
```
#### I want to use a mirror instead of "https://github.com/"
In your Lua config:
```lua
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 {
--
--
}
```

INTRODUCTION *nvim-treesitter-intro*
INTRODUCTION *nvim-treesitter-intro*
Nvim-treesitter provides functionalities for managing treesitter parsers and
compatible queries for core features (highlighting, injections, folds,
indents).
nvim-treesitter wraps the Neovim treesitter API to provide functionalities
such as highlighting and incremental selection, and a command to easily
install parsers.
==============================================================================
QUICK START *nvim-treesitter-quickstart*
QUICK START *nvim-treesitter-quickstart*
To configure `nvim-treesitter`, put this in your `init.lua` file:
>lua
require'nvim-treesitter'.setup {
-- A directory to install the parsers and queries to.
-- Defaults to the `stdpath('data')/site` dir.
install_dir = "/some/path/to/store/parsers",
Install the parser for your language
>
:TSInstall {language}
<
To get a list of supported languages
>
:TSInstallInfo
<
By default, everything is disabled.
To enable supported features, put this in your `init.lua` file:
>
require'nvim-treesitter.configs'.setup {
-- A directory to install the parsers into.
-- If this is excluded or nil parsers are installed
-- to either the package dir, or the "site" dir.
-- If a custom path is used (not nil) it must be added to the runtimepath.
parser_install_dir = "/some/path/to/store/parsers",
-- A list of parser names, or "all"
ensure_installed = { "c", "lua", "rust" },
-- Install parsers synchronously (only applied to `ensure_installed`)
sync_install = false,
-- Automatically install missing parsers when entering buffer
auto_install = false,
-- List of parsers to ignore installing (for "all")
ignore_install = { "javascript" },
highlight = {
-- `false` will disable the whole extension
enable = true,
-- list of language that will be disabled
disable = { "c", "rust" },
-- 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,
},
}
vim.opt.runtimepath:append("/some/path/to/store/parsers")
<
See |nvim-treesitter-modules| for a list of all available modules and its options.
==============================================================================
MODULES *nvim-treesitter-modules*
|nvim-treesitter| provides several functionalities via modules (and submodules),
each module makes use of the query files defined for each language,
All modules are disabled by default, and some provide default keymaps.
Each module corresponds to an entry in the dictionary passed to the
`nvim-treesitter.configs.setup` function, this should be in your `init.lua` file.
>
require'nvim-treesitter.configs'.setup {
-- Modules and its options go here
highlight = { enable = true },
incremental_selection = { enable = true },
textobjects = { enable = true },
}
<
All modules share some common options, like `enable` and `disable`.
When `enable` is `true` this will enable the module for all supported languages,
if you want to disable the module for some languages you can pass a list to the `disable` option.
>
require'nvim-treesitter.configs'.setup {
highlight = {
enable = true,
disable = { "cpp", "lua" },
},
}
<
For more fine-grained control, `disable` can also take a function and
whenever it returns `true`, the module is disabled for that buffer.
The function is called once when a module starts in a buffer and receives the
language and buffer number as arguments:
>
require'nvim-treesitter.configs'.setup {
highlight = {
enable = true,
disable = function(lang, bufnr) -- Disable in large C++ buffers
return lang == "cpp" and vim.api.nvim_buf_line_count(bufnr) > 50000
end,
},
}
<
Options that define or accept a keymap use the same format you use to define
keymaps in Neovim, so you can write keymaps as `gd`, `<space>a`, `<leader>a`
`<C-a>` (control + a), `<A-n>` (alt + n), `<CR>` (enter), etc.
External plugins can provide their own modules with their own options,
those can also be configured using the `nvim-treesitter.configs.setup`
function.
------------------------------------------------------------------------------
HIGHLIGHT *nvim-treesitter-highlight-mod*
Consistent syntax highlighting.
Query files: `highlights.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.
- additional_vim_regex_highlighting: `true` or `false`, or a list of languages.
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.
Defaults to `false`.
>
require'nvim-treesitter.configs'.setup {
highlight = {
enable = true,
custom_captures = {
-- Highlight the @foo.bar capture group with the "Identifier" highlight group.
["foo.bar"] = "Identifier",
},
-- Setting this to true or a list of languages will run `:h syntax` and tree-sitter at the same time.
additional_vim_regex_highlighting = false,
},
}
<
You can also set custom highlight captures
>
lua <<EOF
require"nvim-treesitter.highlight".set_custom_captures {
-- Highlight the @foo.bar capture group with the "Identifier" highlight group.
["foo.bar"] = "Identifier",
}
EOF
<
Note: The api is not stable yet.
------------------------------------------------------------------------------
INCREMENTAL SELECTION *nvim-treesitter-incremental-selection-mod*
Incremental selection based on the named nodes from the grammar.
Query files: `locals.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.
- keymaps:
- init_selection: in normal mode, start incremental selection.
Defaults to `gnn`.
- node_incremental: in visual mode, increment to the upper named parent.
Defaults to `grn`.
- scope_incremental: in visual mode, increment to the upper scope
(as defined in `locals.scm`). Defaults to `grc`.
- node_decremental: in visual mode, decrement to the previous named node.
Defaults to `grm`.
>
require'nvim-treesitter.configs'.setup {
incremental_selection = {
enable = true,
keymaps = {
init_selection = "gnn",
node_incremental = "grn",
scope_incremental = "grc",
node_decremental = "grm",
},
},
}
<
------------------------------------------------------------------------------
INDENTATION *nvim-treesitter-indentation-mod*
Indentation based on treesitter for the |=| operator.
NOTE: this is an experimental feature.
Query files: `indents.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.
>
require'nvim-treesitter.configs'.setup {
indent = {
enable = true
},
}
NOTE: You do not need to call `setup` to use this plugin with the default
settings!
`@indent` *nvim-treesitter-indentation-queries*
Queries can use the following captures: `@indent.begin` and `@indent.dedent`,
`@indent.branch`, `@indent.end` or `@indent.align`. An `@indent.ignore` capture tells
treesitter to ignore indentation and a `@indent.zero` capture sets
the indentation to 0.
Parsers and queries can then be installed with >lua
require'nvim-treesitter'.install { 'rust', 'javascript', 'zig' }
`@indent.begin` *nvim-treesitter-indentation-indent.begin*
The `@indent.begin` specifies that the next line should be indented. Multiple
indents on the same line get collapsed. Eg.
>
(
(if_statement)
(ERROR "else") @indent.begin
)
<
To check installed parsers and queries, use `:checkhealth nvim-treesitter`.
Indent can also have `indent.immediate` set using a `#set!` directive, which
permits the next line to indent even when the block intended to be indented
has no content yet, improving interactive typing.
Treesitter features for installed languages need to be enabled manually in a
|FileType| autocommand or |ftplugin|, e.g. >lua
vim.api.nvim_create_autocmd('FileType', {
pattern = { 'rust', 'javascript', 'zig' },
callback = function()
-- syntax highlighting, provided by Neovim
vim.treesitter.start()
-- folds, provided by Neovim
vim.wo.foldexpr = 'v:lua.vim.treesitter.foldexpr()'
vim.wo.foldmethod = 'expr'
-- indentation, provided by nvim-treesitter
vim.bo.indentexpr = "v:lua.require'nvim-treesitter'.indentexpr()"
end,
})
eg for python:
>
((if_statement) @indent.begin
(#set! indent.immediate 1))
<
==============================================================================
COMMANDS *nvim-treesitter-commands*
:TSInstall {language} *:TSInstall*
Will allow:
>
if True:<CR>
# Auto indent to here
Install one or more treesitter parsers. {language} can be one or multiple
parsers or tiers (`stable`, `unstable`, or `all` (not recommended)). This is a
no-op if the parser(s) are already installed. Installation is performed
asynchronously. Use *:TSInstall!* to force installation even if a parser is
already installed.
`@indent.end` *nvim-treesitter-indentation-indent.end*
An `@indent.end` capture is used to specify that the indented region ends and
any text subsequent to the capture should be dedented.
:TSInstallFromGrammar {language} *:TSInstallFromGrammar*
`@indent.branch` *nvim-treesitter-indentation-indent.branch*
An `@indent.branch` capture is used to specify that a dedented region starts
at the line including the captured nodes.
Like |:TSInstall| but also regenerates the `parser.c` from the original
grammar. Useful for languages where the provided `parser.c` is outdated (e.g.,
uses a no longer supported ABI).
`@indent.dedent` *nvim-treesitter-indentation-indent.dedent*
A `@indent.dedent` capture specifies dedenting starting on the next line.
>
`@indent.align` *nvim-treesitter-indentation-aligned_indent.align*
Aligned indent blocks may be specified with the `@indent.align` capture.
This permits
:TSUpdate [{language}] *:TSUpdate*
>
foo(a,
b,
c)
<
As well as
>
foo(
a,
b,
c)
<
and finally
>
foo(
a,
b,
c
)
<
To specify the delimiters to use `indent.open_delimiter` and
`indent.close_delimiter` should be used. Eg.
>
((argument_list) @indent.align
(#set! indent.open_delimiter "(")
(#set! indent.close_delimiter ")"))
<
Update parsers to the `revision` specified in the manifest if this is newer
than the installed version. If {language} is specified, update the
corresponding parser or tier; otherwise update all installed parsers. This is
a no-op if all (specified) parsers are up to date.
For some languages the last line of an `indent.align` block must not be
the same indent as the natural next line.
Note: It is recommended to add this command as a build step in your plugin
manager.
For example in python:
:TSUninstall {language} *:TSUninstall*
>
if (a > b and
c < d):
pass
Deletes the parser for one or more {language}, or all parsers with `all`.
Is not correct, whereas
>
if (a > b and
c < d):
pass
:TSLog *:TSLog*
Would be correctly indented. This behavior may be chosen using
`indent.avoid_last_matching_next`. Eg.
Shows all messages from previous install, update, or uninstall operations.
>
(if_statement
condition: (parenthesized_expression) @indent.align
(#set! indent.open_delimiter "(")
(#set! indent.close_delimiter ")")
(#set! indent.avoid_last_matching_next 1)
)
<
Could be used to specify that the last line of an `@indent.align` capture
should be additionally indented to avoid clashing with the indent of the first
line of the block inside an if.

If no such file exists, a buffer for a new file in the user's config directory
is created. If {lang} is not specified, the language of the current buffer
is used.
Parameters: ~

• {summary} (`boolean?`, default `false`) print summary of
successful and total operations for multiple languages.
*:TSEditQueryUserAfter*
:TSEditQueryUserAfter {query-group} [{lang}]~
update([{languages}, {opts}]) *nvim-treesitter.update()*
Same as |:TSEditQuery| but edits a file in the `after` directory of the
user's config directory. Useful to add custom extensions for the queries
provided by a plugin.
Update the parsers and queries if older than the revision specified in the
manifest.
==============================================================================
UTILS *nvim-treesitter-utils*
Note: This operation is performed asynchronously by default. For
synchronous operation (e.g., in a bootstrapping script), you need to
`wait()` for it: >lua
require('nvim-treesitter').update():wait(300000) -- max. 5 minutes
Nvim treesitter has some wrapper functions that you can retrieve with:
>
local ts_utils = require 'nvim-treesitter.ts_utils'
<
Parameters: ~
• {languages} `(string[]|string)?` (List of) languages or tiers to update
(default: all installed).
• {opts} `(table?)` Optional parameters:
• {max_jobs} (`integer?`) limit parallel tasks (useful in
combination with {generate} on memory-limited systems).
• {summary} (`boolean?`, default `false`) print summary of
successful and total operations for multiple languages.
Methods
*ts_utils.get_node_at_cursor*
get_node_at_cursor(winnr)~
indentexpr() *nvim-treesitter.indentexpr()*
`winnr` will be 0 if nil.
Returns the node under the cursor.
Used to enable treesitter indentation for a language via >lua
vim.bo.indentexpr = "v:lua.require'nvim-treesitter'.indentexpr()"
*ts_utils.is_parent*
is_parent(dest, source)~
Determines whether `dest` is a parent of `source`.
Returns a boolean.
*ts_utils.get_named_children*
get_named_children(node)~
Returns a table of named children of `node`.
*ts_utils.get_next_node*
get_next_node(node, allow_switch_parent, allow_next_parent)~
Returns the next node within the same parent.
If no node is found, returns `nil`.
If `allow_switch_parent` is true, it will allow switching parent
when the node is the last node.
If `allow_next_parent` is true, it will allow next parent if
the node is the last node and the next parent doesn't have children.
*ts_utils.get_previous_node*
get_previous_node(node, allow_switch_parents, allow_prev_parent)~
Returns the previous node within the same parent.
`allow_switch_parent` and `allow_prev_parent` follow the same rule
as |ts_utils.get_next_node| but if the node is the first node.
*ts_utils.goto_node*
goto_node(node, goto_end, avoid_set_jump)~
Sets cursor to the position of `node` in the current windows.
If `goto_end` is truthy, the cursor is set to the end the node range.
Setting `avoid_set_jump` to `true`, avoids setting the current cursor position
to the jump list.
*ts_utils.swap_nodes*
swap_nodes(node_or_range1, node_or_range2, bufnr, cursor_to_second)~
Swaps the nodes or ranges.
set `cursor_to_second` to true to move the cursor to the second node
*ts_utils.memoize_by_buf_tick*
memoize_by_buf_tick(fn, options)~
Caches the return value for a function and returns the cache value if the tick
of the buffer has not changed from the previous.
`fn`: a function that takes any arguments
and returns a value to store.
`options?`: <table>
- `bufnr`: a function/value that extracts the bufnr from the given arguments.
- `key`: a function/value that extracts the cache key from the given arguments.
`returns`: a function to call with bufnr as argument to
retrieve the value from the cache
*ts_utils.node_to_lsp_range*
node_to_lsp_range(node)~
Get an lsp formatted range from a node range
*ts_utils.node_length*
node_length(node)~
Get the byte length of node range
*ts_utils.update_selection*
update_selection(buf, node)~
Set the selection to the node range
*ts_utils.highlight_range*
highlight_range(range, buf, hl_namespace, hl_group)~
Set a highlight that spans the given range
*ts_utils.highlight_node*
highlight_node(node, buf, hl_namespace, hl_group)~
Set a highlight that spans the given node's range
==============================================================================
FUNCTIONS *nvim-treesitter-functions*
*nvim_treesitter#statusline()*
nvim_treesitter#statusline(opts)~
Returns a string describing the current position in the file. This
could be used as a statusline indicator.
Default options (lua syntax):
>
{
indicator_size = 100,
type_patterns = {'class', 'function', 'method'},
transform_fn = function(line, _node) return line:gsub('%s*[%[%(%{]*%s*$', '') end,
separator = ' -> ',
allow_duplicates = false
}
<
get_available([{tier}]) *nvim-treesitter.get_available()*
- `indicator_size` - How long should the string be. If longer, it is cut from
the beginning.
- `type_patterns` - Which node type patterns to match.
- `transform_fn` - Function used to transform the single item in line. By
default it removes opening brackets and spaces from end. Takes two arguments:
the text of the line in question, and the corresponding treesitter node.
- `separator` - Separator between nodes.
- `allow_duplicates` - Whether or not to remove duplicate components.
Return list of languages available for installation.
*nvim_treesitter#foldexpr()*
nvim_treesitter#foldexpr()~
Parameters: ~
• {tier} `(integer?)` Only return languages of specified {tier} (`1`:
stable, `2`: unstable, `3`: unmaintained, `4`: unsupported)
get_installed([{type}]) *nvim-treesitter.get_installed()*
Return list of languages installed via `nvim-treesitter`.
Note: This only searches `nvim-treesitter`'s (configured or default)
installation directory; parsers and queries from other sources can be
placed anywhere on 'runtimepath' and are not included. To list all, e.g.,
parsers that are installed from any source, use >lua
vim.api.nvim_get_runtime_file('parser/*', true)
Functions to be used to determine the fold level at a given line number.
To use it: >
set foldmethod=expr
set foldexpr=nvim_treesitter#foldexpr()
<
Parameters: ~
• {type} `('queries'|parsers'?)` If specified, only show languages with
installed queries or parsers, respectively.
This will respect your 'foldminlines' and 'foldnestmax' settings.
Note: This is highly experimental, and folding can break on some types of
edits. If you encounter such breakage, hitting `zx` should fix folding.
In any case, feel free to open an issue with the reproducing steps.
==============================================================================
PERFORMANCE *nvim-treesitter-performance*
`nvim-treesitter` checks the 'runtimepath' on startup in order to discover
available parsers and queries and index them. As a consequence, a very long
'runtimepath' might result in delayed startup times.

-- Defines a table of modules that can be attached/detached to buffers
-- based on language support. A module consist of the following properties:
---* @enable Whether the modules is enabled. Can be true or false.
---* @disable A list of languages to disable the module for. Only relevant if enable is true.
---* @keymaps A list of user mappings for a given module if relevant.
---* @is_supported A function which, given a ft, will return true if the ft works on the module.
---* @module_path A string path to a module file using `require`. The exported module must contain
--- an `attach` and `detach` function. This path is not required if `attach` and `detach`
--- functions are provided directly on the module definition.
---* @attach An attach function that is called for each buffer that the module is enabled for. This is required
--- if a `module_path` is not specified.
---* @detach A detach function that is called for each buffer that the module is enabled for. This is required
--- if a `module_path` is not specified.
