Join adds unnecessary commas and spaces, in Python about treesj

[Wansmer]

Check your preset for Python and update ts-parsers.
I checked the given example with the default preset and it works correct.

You're right, it was the preset. I misused last_separator = true by assigning it to both, instead of just split like I'd intended.

The new configuration

-- Set up the treesitter nodes for the Python language.
local lang_utils = require("treesj.langs.utils")
local options = {
    join = { space_in_brackets = false },
    split = { last_separator = true },
}

require("treesj").setup(
    {
        use_default_keymaps = false,
        langs = {
            python = {
                argument_list = lang_utils.set_preset_for_args(options),
                assignment = { target_nodes = { "list", "set", "tuple", "dictionary" } },
                call = { target_nodes = { "argument_list" } },
                dictionary = lang_utils.set_preset_for_dict(options),
                list = lang_utils.set_preset_for_list(options),
                parameters = lang_utils.set_preset_for_args(options),
                set = lang_utils.set_preset_for_list(options),
                tuple = lang_utils.set_preset_for_list(options),
            }
        }
    }
)

Now gives the results I want (trailing separator + no excess spaces)

Thanks for the plug-in btw. It's been super helpful
