Local testing

To be able to locally verify the changes - you should modify your init.lua file to point to your locally installed tree-sitter grammar

local parser_config = require "nvim-treesitter.parsers".get_parser_configs()

parser_config.rego = {
  install_info = {
    url = "/home/user/Documents/tree-sitter-rego", -- local path or git repo
      files = {"src/parser.c"},
    -- optional entries:
      branch = "master", -- 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
  },
  filetype = "rego", -- if filetype does not match the parser name
}
