Combining multiple text objects

[leiteg]

Hello! Is there a straightforward way to combine two text objects into one? I wish to press ]f to move to either the next function or class in the file. Right now, I have the following setup.

require("nvim-treesitter.configs").setup {
    textobjects = {
        move = {
            enable              = true,
            set_jumps           = true,
            goto_next_start     = { ["]f"] = "@function.outer", ["]c"] = "@class.outer" },
            goto_next_end       = { ["]F"] = "@function.outer", ["]C"] = "@class.outer" },
            goto_previous_start = { ["[f"] = "@function.outer", ["[c"] = "@class.outer" },
            goto_previous_end   = { ["[F"] = "@function.outer", ["[C"] = "@class.outer" },
        },
    },
}

I tried swapping @function.outer with the following queries but it did not seem to work:

[
  @function.outer
  @class.outer
]

or

[
  (function_definition)
  (class_definition)
]

Can someone please help me? Thanks in advance!

Found my problem! I was trying to type the query directly in place of the capture name @function.outer. I solved it by moving the query to its own file.

;; ~/.config/nvim/queries/python/textobjects.scm
; extends
[
  (function_definition)
  (class_definition)
] @toplevel

And then configuring nvim-treesitter-textobjects like this.

require("nvim-treesitter.configs").setup {
    textobjects = {
        move = {
            enable              = true,
            set_jumps           = true,
            goto_next_start     = { ["]t"] = "@toplevel" },
            goto_next_end       = { ["]t"] = "@toplevel" },
            goto_previous_start = { ["]t"] = "@toplevel" },
            goto_previous_end   = { ["]t"] = "@toplevel" },
        },
    },
}

The downside is that now I must write the @toplevel query for each filetype, I wish it was possible to "reuse" existing captures.
