Support re-connecting to the LSP server after connection is lost

Hi,

I was looking for a Python linter and spell checker for Jupyter Lab and found both fantastic projects: pyls and jupyterlab-lsp which seem to allow exactly what I was looking for (lint & type check insite the Jupyter Lab environment).

I’ve managed to install pyls (with [all] options) via Anaconda and jupyterlab-lsp via pip.

I also assume that after install, all that must be done is launch Jupyter Lab?

After launching Jupyter Lab, the linter seems to be working (at least partially): I can see linter error codes underlining. But I don’t see other features such as auto-completion, signature help, go to definition, hover, find references, etc:

Unfortunately, I can’t seem to find guidance on how to actually use these tools, activate/deactivate features, reload/refresh linter after fixing a typo in a notebook or text editor… Is there some kind of interface for Jupyter Lab to do such things? How does one begin.

I also don’t know where the config files for jupyterlab-lsp (& pyls?) are stored / supposed to be, except for pycodestyle / flake8 mentioned here.

For example, I’m trying to use the pyls-mypy extension. Where would I go about modifying the configuration:

"pyls":
{
    "plugins":
    {
        "pyls_mypy":
        {
            "enabled": true,
            "live_mode": false
        }
    }
}

And how would I then be able to run/refresh the mypy type checker while working on a notebook or in the Jupyter Lab text editor?

Some user guidance on how to interact with jupyterlab-lsp & pypls would be much appreciated.

Finally, does jupyterlab-lsp with pypls work with Jupyter Notebook server or just Jupyter Lab?

There is nothing to worry about, these hover cache messages should be debug logs not warnings actually.

And yes this was fixed in 1.x. Please upgrade.
