Linting in Jupyter ?

[CrestChristopher]

Can you lint code in Jupyter or is needed ?

What language are you working in? For IPython, at least, there are already some linter integrations published. You can roll your own by implementing a magic.

Looking forward, there is some good stuff happening towards Language Server Protocol integration on jupyterlab-lsp, which will allow linting things that don't have kernels at all!

Oh yeah, let me do some reading :-)

Curious if there is any ongoing effort to adapt a Python LSP engine for IPython's syntax?

I haven't delved into all of the issues but it seems like something that could be beneficial and I'd be interested in helping out.

Given that magics can be registered dynamically, the current approach for JupyterLab-LSP is to replace the magics using predefined, kernel specific regex, see https://github.com/krassowski/jupyterlab-lsp/blob/master/src/magics/defaults.ts. 

This also allows to lint bash in shell expressions and R in rpy2 cells created with cell magics.

Please also see the documentation/discussion in https://github.com/krassowski/jupyterlab-lsp/blob/master/examples/Magics_and_rpy2.ipynb - I would really want to hear your opinion on this approach.
