Cannot get the parser to work with nvim-treesitter

[Chamal1120]

I added the parser.c file for my nvim-treesitter config as below.

treesitter.lua

return {
  "nvim-treesitter/nvim-treesitter",
  lazy = false,
  build = ":TSUpdate",
  config = function()
    -- Register custom parser for ballerina grammar
    local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
    parser_config.ballerina = {
      install_info = {
        url = "~/.config/nvim/tree-sitter-parsers/tree-sitter-ballerina",
        files = { "src/parser.c" },
        generate_requires_npm = false,
      },
      filetype = "ballerina",
    }

    -- treesitter configs
    local config = require("nvim-treesitter.configs")
    config.setup({
      auto_install = true,
      highlight = {
        enable = true,
        disable = { "latex" },
        additional_vim_regex_highlighting = false,
      },
      indent = { enable = true },
    })
  end,
}

Also added .bal as a detectable file type for neovim as below.

init.lua

-- Custom filetype matchings
vim.filetype.add({
  extension = {
    bal = 'ballerina' -- Detect as bellerina files
  },
  pattern = {
    [".*/hypr/.*%.conf"] = "hyprlang", -- Detect as hyprlang files
  },
})

When I open a .bal file nvim-treesitter even showed the "installing ballerina tressitter.." message as well.

But I don't get proper still syntax highlighting yet.

It shows like below

It is not shown in :TSModuleInfo either

I might be doing this wrong. Please correct me if it is the case.

I think you need to give queries to nvim as well (by default it picks up these https://github.com/nvim-treesitter/nvim-treesitter/tree/master/queries). What I have done is put them in queries/ballerina in my nvim config dir. These is my queries https://gist.github.com/heshanpadmasiri/caaaabbf1ec82aedaa0ecbf19d08b238. I haven't used ballerina in nvim in a while so not sure if they work still though

Will give it a try
