-- ============================================================
do
  -- [[ Intro to `vim.pack` ]]
  -- `vim.pack` is a new plugin manager built into Neovim,
  --  which provides a Lua interface for installing and managing plugins.
  --
  --  See `:help vim.pack`, `:help vim.pack-examples` or the
  --  excellent blog post from the creator of vim.pack and mini.nvim:
  --  https://echasnovski.com/blog/2026-03-13-a-guide-to-vim-pack
  --
  --  To inspect plugin state and pending updates, run
  --    :lua vim.pack.update(nil, { offline = true })
  --
  --  To update plugins, run
  --    :lua vim.pack.update()
  --
  --
  --  Throughout the rest of the config there will be examples
  --  of how to install and configure plugins using `vim.pack`.
  --
  --  In this section we set up some autocommands to run build
  --  steps for certain plugins after they are installed or updated.

  local function run_build(name, cmd, cwd)
    local result = vim.system(cmd, { cwd = cwd }):wait()
    if result.code ~= 0 then
      local stderr = result.stderr or ''

      if output == '' then output = 'No output from build command.' end
      vim.notify(('Build failed for %s:\n%s'):format(name, output), vim.log.levels.ERROR)
    end
  end

  -- This autocommand runs after a plugin is installed or updated and
  --  runs the appropriate build command for that plugin if necessary.
  --
  -- See `:help vim.pack-events`
  vim.api.nvim_create_autocmd('PackChanged', {
    callback = function(ev)
      local name = ev.data.spec.name
      local kind = ev.data.kind
      if kind ~= 'install' and kind ~= 'update' then return end

      if name == 'telescope-fzf-native.nvim' and vim.fn.executable 'make' == 1 then
        run_build(name, { 'make' }, ev.data.path)
        return
      end

      if name == 'LuaSnip' then
        if vim.fn.has 'win32' ~= 1 and vim.fn.executable 'make' == 1 then run_build(name, { 'make', 'install_jsregexp' }, ev.data.path) end
        return
      end

      if name == 'nvim-treesitter' then
