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

Please refer to the [adding parsers](https://github.com/nvim-treesitter/nvim-treesitter#advanced-setup) section on the nvim-treesitter page for more information.

Example config:
```lua
local parser_config = require'nvim-treesitter.parsers'.get_parser_configs()
parser_config.dfraw = {
	install_info = {
		url = 'https://github.com/JellyApple102/tree-sitter-dfraw',
		files = { 'src/parser.c' },
		branch = 'main'
	},
	filetype = 'text',
	used_by = { 'dfraw' }
}
```
Wrap in `lua << EOF` and `EOF` to use in `init.vim`.\
Then run `:TSInstall dfraw` to install the parser.

In order for syntax highlighting to work you copy `queries/highlights.scm` file from this repo to your nvim-treesitter location `queries/dfraw/highlights.scm`.
More information can be found on the nvim-treesitter page.

By default it is setup to start for any file of type 'text' or 'dfraw'. If you would not like to use it for all text files you can add a custom filetype to neovim.
Example `.config/nvim/scripts.vim`:
```vim
if did_filetype()
	finish
endif
if getline(1) =~# '[a-z_]'
	setfiletype dfraw
endif
```
This will match any file whose first line is just lowercase letters_and_underscores, and set the filetype to 'dfraw'.
Than change the config option `filetype = 'dfraw'` and remove the `used_by` option to only use 'dfraw' type files.

More information on custom filetypes [here](https://neovim.io/doc/user/filetype.html#new-filetype).

# Highlight Colors

Feel free to change the highlight groups set by `highlights.scm`. I have found that some colors schemes use the same or similar colors for different groups.
I have set them to what I like best using the [tokyonight](https://github.com/folke/tokyonight.nvim) theme.

Use `:highlight` to view your current highlight groups and colors.
Gotta change tabwidth.
