How to use treesitter-textobjects

[oiiiiiiii]

The readme states that the treesitter-textobjects addon can be used for the surroundings. However, I didn't find anything in the docs that describes how to use them. Did I miss anything?

That plugin provides additional motions you can use to surround delimiters around, e.g. add parentheses around a loop

[kylechui]

Another use case is to define the find key in a surround to customize what delimiters you are modifying. For example, the default configuration for f surround uses the @call.outer query defined by the treesitter text objects plugin when available.

Thank you! :)

@kylechui sorry for pinging you again, but back when I asked the question I didn't get to actually implement it and now that I have the time I can't get it to work. I basically want to define a condition-surround with the treesitter-textobject "@conditional.outer". I want to press dso to remove the surrounding if-statement, e.i. transform

if true {
    a = "hello"
}

to

a = "hello"

I tried using this setup, similar to the one you linked

            surrounds = {
                ["o"] = {
                    find = function()
                        if vim.g.loaded_nvim_treesitter then
                            local selection = require("nvim-surround.config").get_selection({
                                query = {
                                    capture = "@conditional.outer",
                                    type = "textobjects",
                                },
                            })
                            if selection then
                                return selection
                            end
                        end
                        return require("nvim-surround.config").get_selection({ pattern = "[^=%s%(%){}]+%b()" })
                    end,
                }

but it doesn't work. How would I implement this / what am I doing wrong?

Honestly I think the query feature might be broken/never worked in the first place; currently trying to resolve it as a part of removing nvim-treesitter as a hard dependency in favor of vim.treesitter. Have been a bit busy the past few weeks though
