## Text objects: select
Define your own text objects mappings

## Features and Roadmap
Check [`:h nvim-treesitter-commands`](doc/nvim-treesitter.txt) for a list of all available commands.
The goal of `nvim-treesitter` is both to provide a simple and easy way to use the interface for Treesitter in Neovim,
but also to add some functionalities to it:
Some of these features are:
- [x] Incremental selection
- [x] Syntax based code folding (`set foldmethod=expr foldexpr=nvim_treesitter#foldexpr()`)
- [x] Consistent syntax highlighting (the api is not quite stable yet)
- [x] Statusline indicator (`require'nvim-treesitter'.statusline(size)`)
You can find the 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!
## Available Modules
- `highlight`: Consistent syntax highlighting.
- `incremental_selection`: Syntax based selection.
- `refactor.highlight_definitions`: Syntax based definition and usage highlighting.
- `refactor.smart_rename`: Syntax based definition and usage renaming.
- `refactor.navigation`: Syntax based definition listing and navigation.
* List all definitions
* Go to definition
- `textobjects`: Vim textobjects defined by treesitter queries
## Defining Modules
Users and plugin authors can take advantage of modules by creating their own. Modules provide:
- Treesitter language detection support
- Attach and detach to buffers
- Works with all nvim-treesitter commands
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
}
}
```
Modules can consist of the following properties:
- `module_path`: 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`: A list of languages that this module is disabled for. This is usually overridden by the user.
- `is_supported`: A function that takes a language and determines if this module supports that language.
- `attach`: A function that attaches to a buffer. This is required if `module_path` is not provided.
- `detach`: A function that detaches from a buffer. This is required if `module_path` is not provided.
## Utils
You can get some utility functions with
```lua
local ts_utils = require 'nvim-treesitter.ts_utils'
```
More information is available in the help file (`:help nvim-treesitter-utils`).
## Supported Languages

For `nvim-treesitter` to work, we need to use query files such as those you can find in

each module makes use of the query files defined for each language,
you can add your own queries too, see |nvim-treesitter-query-extensions|.

Syntax aware |text-objects|.

Text object selection~
Define your own text objects mappings
similar to `ip` (inner paragraph) and `ap` (a paragraph).
Query files: `textobjects.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.
- keymaps: map of keymaps to a tree-sitter query
(`(function_definition) @function`) or capture group (`@function.inner`).

like function parameters or arguments.
Query files: `textobjects.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.

or previous function.
Query files: `textobjects.scm`.
Supported options:
- enable: `true` or `false`.
- disable: list of languages.
- goto_next_start: map of keymaps to a tree-sitter capture group (`@function.outer`).

the text object.
