How to install in Neovim

Note: this step is only temporary. The highlighter will eventually be added to the nvim-tressitter project to be included with neovim.

1. Add the following to the neovim (lua) config:

   local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
   parser_config.jakt = {
     install_info = {
       url = "https://github.com/demizer/tree-sitter-jakt.git", -- local path or git repo
       files = {"src/parser.c", "src/scanner.c"},
       -- optional entries:
       branch = "main", -- default branch in case of git repo if different from master
       generate_requires_npm = false, -- if stand-alone parser without npm dependencies
       requires_generate_from_grammar = false, -- if folder contains pre-generated src/parser.c
     },
   }

2. Manually install the highlighter

   See nvim-treesitter instructions

   highlights.scm is contained in the tree-sitter-jakt repository.

   mkdir -p ~/.config/nvim/queries/jakt
   cp queries/* ~/.config/nvim/queries/jakt/
   

3. Install tree-sitter-jakt using neovim

   :TSInstall jakt
   

4. checkhealth in neovim

   :checkhealth
   

5. jakt should be contained in the tree-sitter parsers and should it should have a check under highlight.

6. Configure filetype detection

   vim.filetype.add { extension = { jakt = "jakt"} }

7. Open a jakt file
