[mini.ai] Functions as an alternative text-object for tags

[igorlfs]

Hey,

mini.ai ships many textobjects, including a tag one, which can be used with t. However, the default object does not cover every edge case. For the longest time, I've been using a custom object, taken from Lazyvim. But it also misses some even crazier edge cases.

Today I was investigating this situation and realized that a better solution can be achieved with nvim-treesitter-textobjects. It just so happens that tags (elements) are "tagged" as functions. Which means that if you're using

f = ai.gen_spec.treesitter({ a = "@function.outer", i = "@function.inner" }),

It will also work flawlessly with tags! Still getting used to it, but it's a creative "workaround" that I felt I had to share!

Thanks for sharing!

This is more or less recommended way to handle more complex tags. But instead of globally overriding f, the suggested approach is to:

• Create filetype plugin(s) for filetype(s) you want to have "enhanced" tree-sitter based tag textobject. For example, '~/.config/nvim/after/ftplugin/html.lua'.

• Set buffer-local config that sets t textobject to use gen_spec.treesitter. So something like this:

  if _G.MiniAi ~= nil then
    vim.b.miniai_config = {
      custom_textobjects = {
        t = MiniAi.gen_spec.treesitter({ a = '@function.outer', i = '@function.inner' }),
      },
    }
  end
