How to configure pyls?

What I am trying to do…

… is to configure pyls (pycodestyle) to ignore some errors. If possible, I would like to disable pycodestyle completely and go only with pyflakes. (I use black as formatter, which produces a lot of “false positives” in pycodestyle)

How I would like to learn how to do it…

It would be great to see an example of a more extensive jupyter-lab configuration for jupyterlab-lsp. So far the only example I found is this generic “dummy”-snippet here:

{
  "LanguageServerManager": {
    "language_servers": {
      "a-language-server-implementation": {
        "argv": ["/absolute/path/to/a-language-server", "--stdio"],
        "languages": ["a-language"]
      }
    }
  }
}

I have found the necessary pyls configuration in this schema file, but I don’t know if/how this can be integrated/overwritten using jupyter labs extensions settings.

Thanks!

I think that switching to flake8 will require the configuration GUI, not sure if this can be achieved straightaway. I will try to expose some of the settings in the 0.8 release.

@dynobo from past experiences with pyls the best way to avoid running the checkers you want is to NOT install the others: when you install pyls, use pip install python-language-server instead of pip install python-language-server[all] then install only the checkers you need/want (i.e pip install rope pyls-black etc.). Right now you can probably pip uninstall pycodestyle and any other plugin you know it is doing extra checks or changes you don’t want.
