installed plugins not being used

[petergaultney]

i have pylsp_black and pylsp_mypy installed, in the correct/same venv, but they're not getting used.

I have looked at your code and I don't understand how this project even knows to try to import them so they can register their hooks. Presumably something needs to run the pylsp_mypy script, but nothing seems to be doing that.

pylsp is running, and you can see from its path that the other plugins are installed side by side. But nothing having to do with mypy is running.

As far as I can tell, my config has both of these plugins enabled:

I do see this in the logs as well - it's the only thing i can find regarding linting.

[Trace - 11:51:07 PM] Received notification '$/progress'.
Params: {
  "token": "5893f6c0-5810-4e1f-a371-612fde6e82eb",
  "value": {
    "kind": "begin",
    "title": "lint: pydocstyle"
  }
}

is pydocstyle somehow overriding mypy's hook registration for linting?

Hey @petergaultney, thanks for reporting. Unfortunately, this is not a problem we can help you to solve here. Instead, you need to report it in the repo of the editor or IDE you're using, so their developers can give you a hand to understand what's happening.

I can only assure you those plugins work as expected in other IDEs, e.g. Spyder.

[petergaultney]

out of curiosity, can you explain the mechanism of action for loading the plugin? does the client have to explicitly request the plugin be enabled? I wasn't able to find this documented in the repo, and I spent half an hour looking at your code to find the part where it loads plugins by name or something like that and could not find it.

Plugins are loaded using the pluggy package. That's done in the Config.__init__ method:

https://github.com/python-lsp/python-lsp-server/blob/develop/pylsp/config/config.py

does the client have to explicitly request the plugin be enabled?

It depends on the plugin's configuration. Some are enabled by default (e.g. python-lsp-black) and others aren't.
