Question

Is there a way to configure a Python multiline string with mini.ai? I tried using gen_spec.pair but it does not accept multiple characters when using the balanced type.

Another non-solution is using the treesitter group @string.documentation as this only applies to docstrings, not multiline strings generally. For example:

x = """hello
world"""

This is not a docstring, so a treesitter text object for that group does not help.

I also tried creating composed patterns but could not get them to be balanced.

Yes, this is possible with the following setup:

• Create a '~/.config/nvim/after/ftplugin/python.lua' file with the following content:

  vim.b.miniai_config = {
    custom_textobjects = {
      -- Match triple " or ' pair, `i` textobject is inside of them
      s = { { '""".-"""', "'''.-'''" }, '^...().*()...$' },
    },
  }

• Use it like is and as. This will only work for Python files (i.e. in buffers with python filetype).

This doesn't seem to be balanced. For example:

"""hello""" x """world"""

If you use vis when the cursor is at x, it selects the x with the surrounding whitespace. But this shouldn't be valid since the strings in this case are hello and world.

Yes, there is no good/easy way with Lua patterns to find balanced pair if parts consist from more than one character. This is the at least 95% solution with just one line, which I should be good enough here.
