No stubs for brython for PyCharm - crucial to make it popular (coding efficiency - heart of Python).

I need autocomplete during coding in PyCharm. Python heart is fast coding so it is crucial.

I can not import really module from browser import document since no such file - PyCharm will allow autocompletion.

I think you can generate *.pyi stubs to allow completion. It can be generated in console. I do not know how to do it but you can.

Without autocompletion coding is very hard for beginners and slow for experts. That is true obstacle to make it popular.

For example I can use brython (it is not productive) but my younger programmers will have very big problems.

I’ve created this module https://github.com/Real-Gecko/brython-stubs as a proof of concept.

Issues I see with this approach:

1. Separate repo.
2. pyi files are not generated from brython but are created manually.
3. it adds extra package browser to lib which actually contains only stubs but no code, so possible name conflict with another modules. Using name browser-stubs did not work with VSCode imports. Putting stubs to brython folder did not work, import needed to be brython.browser.

Ok, I redid the PR and now we have brython-stubs submodule that can be put on PyPi I guess. It installs browser folder which contains .pyi files for Brython browser at least. However they’re incomplete as no JS modules are parsed. Preposition for Typescript remains 😄
