flint-syntax.nvim

The Flint syntax highlighter for Neovim. To add the highlighter to Neovim just add these lines inside your lazyvim setup section like this:

require('lazy').setup({
  -- ...
  {
    'flint-lang/flint-syntax.nvim',
    ft = 'flint',
    config = function()
      -- Set the tab width to 4
      vim.cmd [[
          augroup flint_indent
            autocmd!
            autocmd FileType flint setlocal tabstop=4 shiftwidth=4 noexpandtab
          augroup END
      ]]

      -- LSP configuration
      local lspconfig = require 'lspconfig'
      local configs = require 'lspconfig.configs'

      -- Define flint LSP if not already defined
      if not configs.flint then
        configs.flint = {
          default_config = {
            cmd = { 'fls' }, -- Make sure this is in your PATH
            filetypes = { 'flint' },
            root_dir = function(fname)
              return lspconfig.util.find_git_ancestor(fname) or vim.fn.getcwd()
            end,
            settings = {},
          },
          docs = {
            description = [[
Flint Language Server Protocol implementation.
Make sure 'fls' is in your PATH.
            ]],
          },
        }
      end

      -- Setup the LSP
      lspconfig.flint.setup {}
    end,
  },
  -- ...
})

That's it, no more setup required than this! By just adding the above code to your init.lua file you not only have added syntax highlighting support for Flint but also set up the fls too. Note that you need to have the fls installed for it to work, so it needs to be in your PATH variable.
