EmacsConf 2020: State of Retro Gaming in Emacs

Emacs flexibility means it's as daunting as you want it to be. I taught myself the basics years ago and ever since it has completely changed the way I view programming. Lately I'm mostly using it for ad-hoc text processing with macros, but I would love to use it as my Python / C++ IDE again some day.

I use python-lsp... No that bad. Still have to figure out how to turn off the PEP 8 code style warnings because there are too many of them (I prefer to clean the code style after having working code). It's not as good as PyCharm though, but nice for a start, and rather stable.

Curious what you prefer about PyCharm over emacs + LSP.

I'm a pretty poor PyCharm power-user, so wondering what I"m missing.

PyCharm, like most IntelliJ IDEs, has excellent refactoring capabilities, much better than what LSP currently offers.

E.g. extract method, extract class, advanced navigation like "data flow to here" etc

They may not work in extremely dynamic Python code (e.g. they will obviously not work past an `exec`).

This is the biggest flaw in LSP (for Python at least), right now.

How difficult is it to implement basic extract function/method functionality?

I'd be tempted to try doing it, as I would absolutely love to have this in Emacs.

I'd be happy to help here too, let me know. I can try to hack some elisp together tomorrow.

Looks like rope would be a decent place to start.

I think some basic extract method has made it into lsp-mode or some enhancement, I have been seeing it for Go at least. That could serve as an inspiration.

I haven't honestly played around with it though to see if it successfully converts local variables to parameters/return values though, which would be the biggest time saver.
