# completion-treesitter

Treesitter source and more for [completion-nvim](https://github.com/haorenW1025/completion-nvim).

This is a basic completion source based on the treesitter api of neovim.

**Since v0.1 this only contains a completion source. All other features are being migrated to nvim-treesitter**

# Quickstart

This plugin requires the following plugins:

- [completion-nvim](https://github.com/haorenW1025/completion-nvim)

- [nvim-treesitter](https://github.com/nvim-treesitter/nvim-treesitter)

Install them like this (vim-plugged or your favorite package manager):

```vim

Plug 'haorenW1025/completion-nvim'

Plug 'nvim-treesitter/nvim-treesitter'

Plug 'nvim-treesitter/completion-treesitter'

```

## Completion

Configure `completion-nvim` as you desire, you can use the `ts` source for `lua`, `python` and `c` filetypes, for example :

```vim

" Configure the completion chains

let g:completion_chain_complete_list = {

			\'default' : {

			\	'default' : [

			\		{'complete_items' : ['lsp', 'snippet']},

			\		{'mode' : 'file'}

			\	],

			\	'comment' : [],

			\	'string' : []

			\	},

			\'vim' : [

			\	{'complete_items': ['snippet']},

			\	{'mode' : 'cmd'}

			\	],

			\'c' : [

			\	{'complete_items': ['ts']}

			\	],

			\'python' : [

			\	{'complete_items': ['ts']}

			\	],

			\'lua' : [

			\	{'complete_items': ['ts']}

			\	],

			\}

" Use completion-nvim in every buffer

autocmd BufEnter * lua require'completion'.on_attach()

```

Open a buffer of a supported filetype and enjoy !

# Using parsers

## From nvim-treesitter

To install a parser run the following command in nvim for the supported language of your choice :

```vim

:TSInstall lua

```

## From source

To use a parser for one of the supported languages clone the parser sources (the python parser for example) :

```sh

git clone https://github.com/tree-sitter/tree-sitter-python.git

```

Then compile it :

```sh

gcc -o parser.so -shared src/parser.c src/scanner.cc -I./src -lstdc++

```

An move it to neovim config files :

```sh

mv parser.so ~/.config/nvim/parser/{lang}.so

```

Where `{lang}` is the filetype corresponding to the parser's language (`python` in above example).

# Examples usages

Some examples usages of the plugin, not only for completion.

All of these functionnalities are available for all supported filetypes.

# Goals

The aim of the plugin is mainly to fiddle a bit with treesitter, and a nice way is completion, but there is many things we can do with it.

There is still some goals for the plugin:

  - As hackable as possible

  - As fast as possible
