[query] Which is better to use...?

[MarioMey]

Seeing change_order.py, I realized that you used @contextmanager functions to use with statement. You didn't use them in other scripts. I would like to know why you used it. Is it better? Does it close automatically the reference or something like that?

Another question: can I ask this queries here? 😁

@MarioMey I've used context managers a lot in Scripted-text. Yes, yes as soon as its leaves closure.
You might also want to use ExitStack since it can select context mangers based on condition. It also reduces nesting level e.g consider this code:

def sanic_effect(self):
    "really fast speed text scrolling(filter)"
    # add filter scroll to source if not present,
    self.update_text(self._scripted_text)
    with source_ar(self.source_name) as source, filter_ar(
        source, "py_scroll"
    ) as scroll:
        if scroll is None:
            with data_ar() as settings:
                obs.obs_data_set_int(settings, "speed_x", 5000)
                with p_source_ar("scroll_filter", "py_scroll", settings) as _source:
                    obs.obs_source_filter_add(source, _source)

        with data_ar(scroll) as filter_settings:
            obs.obs_data_set_int(filter_settings, "speed_x", 5000)
            obs.obs_source_update(scroll, filter_settings)
            if self.duration // self.refresh_rate <= 3:
                obs.obs_source_filter_remove(source, scroll)
                self.duration = 0

Using ExitStack unreleased version

def sanic_effect(self):
    "really fast speed text scrolling(filter)"
    # add filter scroll to source if not present,
    self.update_text(self._scripted_text)
    with ExitStack() as stack:
        source = stack.enter_context(source_ar(self.source_name))
        scroll = stack.enter_context(filter_ar(source, "py_scroll"))
        if scroll is None:
            settings = stack.enter_context(data_ar())
            obs.obs_data_set_int(settings, "speed_x", 5000)
            _source = stack.enter_context(
                p_source_ar("scroll_filter", "py_scroll", settings)
            )
            obs.obs_source_filter_add(source, _source)
        filter_settings = stack.enter_context(data_ar(scroll))
        obs.obs_data_set_int(filter_settings, "speed_x", 5000)
        obs.obs_source_update(scroll, filter_settings)
        if self.duration // self.refresh_rate <= 3:
            obs.obs_source_filter_remove(source, scroll)
            self.duration = 0

Sure, I think we can try using Discussions
