How to get IDE support

[hofbi]

Hi,

as part of your README, you mention

Thanks to the virtualenv, you can open the project in an editor like PyCharm and have working auto-complete, jump-to-definition

It is not fully clear to me how to get there? Do I have to tell the IDE where to find the venv inside the sandbox?

I'm also wondering how to do the IDE integration. Especially being able to use the debugger would be essential. Thanks!

I've never really tried this, but I think the idea is to create a venv with everything using the py_venv rule. There was a bug before 0.7.x, where the created venv has invalid paths.

Would the idea then be to have a py_venv target for the entire repo to provide the IDE venv?

[mattem]

A venv can be created for any py_test or py_binary target, via bazel run //the/binary.venv, rules_py will create a venv for that target in the directory next to the target.

Would the idea then be to have a py_venv target for the entire repo to provide the IDE venv?

This really depends on a number of factors. If there is multiple Python dependency closures in the repo, or Python versions, then a single venv will cause conflicts. It also depends on the size of the repo, perhaps, as opening the root of a repo and attempting to install all of the dependencies would be too large, so a finer grained "per service" and "per target" approach is needed.
