tree-sitter implementation for feint

NOTE: This is a work in progress.

Installation

1. Install the tree-sitter CLI with brew install tree-sitter or the equivalent on your platform.

2. Clone this repo:

   git clone git@github.com:wylee/tree-sitter-feint.git ~/path/to/tree-sitter-feint

Neovim

NOTE: The following seems rather convoluted. Hopefully this can be simplified eventually.

NOTE: Adjust paths as needed in all the code snippets below.

1. Install the nvim-treesitter plugin. You can use pathogen, vim-plug, etc.

2. Link the tree-sitter queries used for syntax highlight:

   ln -s ~/path/to/tree-sitter-feint/queries ~/.config/nvim/bundle/nvim-treesitter/queries/feint

3. Add the following to your ~/.config/nvim/init.lua:

   -- NOTE: This line is only needed if you have an init.vim that you
   --       need to load too (e.g., to load your plugins).
   vim.cmd [[source ~/.config/nvim/legacy.vim]]
   
   vim.filetype.add({
     extension = {
       fi = "feint",
     },
   })
   
   local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
   
   parser_config.feint = {
     install_info = {
       url = "~/path/to/tree-sitter-feint",
       files = {"src/parser.c", "src/scanner.cc"},
       generate_requires_npm = false,
       requires_generate_from_grammar = false,
     },
     filetype = "fi",
   }
   
   require"nvim-treesitter.configs".setup {
     highlight = {
       enable = true,
       additional_vim_regex_highlighting = false,
     },
     indent = {
       enable = true,
     },
   }
   
   local ft_to_parser = require"nvim-treesitter.parsers".filetype_to_parsername
   ft_to_parser.feint = "feint"

4. Run nvim and install the feint tree-sitter impementation:

   :TSInstall feint
