How to install in Neovim?

[tms-tham]

Nvim

I followed the instructions in this link, but it doesn't work. This is my configuration

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

  treesitter_parser_config.slim = {
    install_info = {
      url = "https://github.com/kolen/tree-sitter-slim.git",
      files = {"src/parser.c", "src/scanner.c"},
      branch = "master",
    }
  }

  vim.treesitter.language.register("slim", "slim")

  vim.filetype.add({
    extension = {
      slim = 'slim'
    }
  })

I never used neovim, today I tried to load this grammar in neovim. My ~/.config/nvim/init.lua config:

local vim = vim
local Plug = vim.fn['plug#']

vim.call('plug#begin')
Plug('nvim-treesitter/nvim-treesitter', { ['do'] = ':TSUpdate'} )
vim.call('plug#end')

local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
parser_config.slim = {
   install_info = {
      url = "https://github.com/kolen/tree-sitter-slim",
      files = {"src/parser.c", "src/scanner.c"},
      requires_generate_from_grammar = false,
   },
   filetype = "slim",
}

After that, running :TSInstall slim completes successfully. However, for this grammar to be usable for editing slim files, at least queries for highlighting should be created, something like this. I don't have experience with Neovim.
