Setting up pycharm for poetry, black etc.
Setting up the poetry environment
Create a new project, point it at the folder with the sources, and instead of trying to use an existing poetry environment, just create a new one. It will use the same virtualenv as usual when running poetry shell inside that directory. Nice!1
The project uses ./src/package_name layout (220105-1142 Order of directories inside a python project), which created issues in the editor (tests and files run fine though). Fixed by adding ./src as Source Root, then it parses all imports as packgae name
Setting up black
Black as external tool
Official Black instructions for Pycharm worked for me: Editor integration — Black 21.12b0 documentation
Creating a binding for black in ideavim
This was tricky! I found a really nice post2 that showed how to spawn vim from ideavim. I tried following its example but
nmap <leader>f :action Tool_External_Tools_black<CR>
didn’t work.
The post mentioned running :actionlist inside the editor to get the list of all available actions (I used to rely on a github gist for that!). Well, would you believe, External Tools has a space inside it.
So the correct line is:
nmap <leader>f :action Tool_External Tools_black<CR>
Wow. …Wow.
In any case works now!

Reddit suggested using
poetry env info, which gives info about the environment, and add that interpreter to pycharm directly ↩︎ -
Customising IdeaVim - Chathura Colombage; His example .ideavimrc from that post is really really interesting, TODO steal ideas! ↩︎
