@clason it does not seem to be possible to set operatorfunc to a Lua function. I would prefer to wait for this feature or a general way to make a Lua function repeatable (without

The best thing that I could get working was (see #343)

        local function fn()
          if opts.repeatable then
            _G._nvim_treesitter_textobject_last_function = function()
              require("nvim-treesitter.textobjects." .. submodule)[function_call](query)
            end
            vim.o.opfunc = "v:lua._nvim_treesitter_textobject_last_function"
            vim.api.nvim_feedkeys("g@l", "n", false)
          else
            require("nvim-treesitter.textobjects." .. submodule)[function_call](query)
          end
        end
        vim.keymap.set(
          keymap_modes,
          mapping,
          fn,
          { buffer = bufnr, silent = true, remap = false, desc = mapping_description }
        )

since opfunc seems to insist on a string

That's right; this is tracked here: https://github.com/neovim/neovim/issues/18132 and here: https://github.com/neovim/neovim/issues/14157

Your workaround seems similar to https://github.com/neovim/neovim/issues/14157#issuecomment-1320787927
