# treesitter-unit
A tiny [Neovim](https://neovim.io/) plugin to deal with [treesitter](https://github.com/tree-sitter/tree-sitter) units.
A unit is defined as a treesitter node including all its children.
It allows you to quickly select, yank, delete or replace language-specific ranges.
For inner selections, the main node under the cursor is selected.
For outer selections, the next node is selected.
## Installation
Requirements: [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter) including a parser for your language
For [vim-plug](https://github.com/junegunn/vim-plug):
```
Plug 'David-Kunz/treesitter-unit'
```
For [packer](https://github.com/wbthomason/packer.nvim):
```
use 'David-Kunz/treesitter-unit'
```
## Usage
### Select treesitter unit
You can select the current treesitter unit
```
:lua require"treesitter-unit".select(outer?)
```
This function takes an optional Boolean flag to specify if the outer scope should be selected as well, default `false`.
For operations like delete, change, ... please see section "Useful mappings".
### Automatic Highlighting
You can toggle automatic highlighting for the current treesitter unit.
```
:lua require"treesitter-unit".toggle_highlighting(higroup?)
```
As an optional parameter you can specify the highlight group, default: `"CursorLine"`.
Alternative: `enable_highlighting(higroup?)` and `disable_highlighting()`.
### Useful mappings
For init.vim:
```
xnoremap iu :lua require"treesitter-unit".select()
xnoremap au :lua require"treesitter-unit".select(true)
onoremap iu :lua require"treesitter-unit".select()
onoremap au :lua require"treesitter-unit".select(true)
```
For init.lua:
```
vim.api.nvim_set_keymap('x', 'iu', ':lua require"treesitter-unit".select()', {noremap=true})
vim.api.nvim_set_keymap('x', 'au', ':lua require"treesitter-unit".select(true)', {noremap=true})
vim.api.nvim_set_keymap('o', 'iu', ':lua require"treesitter-unit".select()', {noremap=true})
vim.api.nvim_set_keymap('o', 'au', ':lua require"treesitter-unit".select(true)', {noremap=true})
```
Examples:
- `viu` to select the inner unit
- `cau` to change the outer unit
