Is there an alternative to call_plugin()?

[dkondor]

output_t::call_plugin() was removed in #1674 (as plugins are not created for each output anymore). Is there a replacement for its functionality? I would like to be able to programmatically activate other plugins (as if the user pressed the associated keybinding), and this was a very convenient feature, since it only required the name of the action (e.g. "scale/toggle").
Thanks!

The idea was to enable calling plugins via IPC, replacing the call_method in this way. It would also allow additional parameters to be passed. I have yet to decide on a good API, I think it would make sense to have this ready before 0.8.

Forgot to mention: IPC methods can of course be also called from other plugins, and for many plugins we'd want a simple wrapper which combines a regular binding + ipc call.

Thank you, this makes sense!

#1821 contains a first version of the helper I was speaking of, ipc_activator_t. We will need to gradually replace plain old activators with the new ipc_activator, feel free to send PRs for plugins you want to see updated ;)

In #1864 I have added support for these ipc-activators to the scale plugin since that's what you mentioned here. Other plugins can be handled similarly, PRs welcome.

Here's an example of how to call scale (haven't tested but should work):

nlohmann::json data;
data["output_id"] = output->get_id();

shared_data::ref_ptr_t<ipc::method_repository_t> repo;
repo->call_method("scale/toggle", data);
