Python VS Code extension

[akosyakov]

I've tried to run VS Code extension for Python. It was installed sucessfully, but it does not seem to work.

Contributions are not localized:

No language highlighting and support:

Errors from the backend:

• Fix configuration contribution and workspace.getWorkspaceFolder implementation #4458
• Move python language contribution to textmate-grammars package #4493
• Fix progress creation #4480

yes some LSP extensions are also providing debug stuff but debug stuff is not yet there (not even mocked)
but @tolusha is working on it

[akosyakov]

@benoitf ok

Also turned out that this extension does not include python language definition but relies on build-in VS Code extension (which is not on marketplace): https://github.com/Microsoft/vscode/tree/master/extensions/python

I will try to run them together when VS Code debug APIs are implemented.

@akosyakov Any updates on this after the merge?

[akosyakov]

@mannau i would try to give it a spin again

[akosyakov]

#3815 is needed for it

[tsmaeder]

It seems there already is a python grammar registered in the current python extension for theia. We could just migrate that to the "textmate-grammars" package.

[akosyakov]

@tsmaeder sounds good for now, eventually we don't want to support our textmate-grammars but consume them from source (VS Code)

[tolusha]

Now it is possible to use VS Code python extension [1]

Still have some errors in console

root ERROR Warning: Encountered two children with the same key, `$(refresh~spin) Refreshing Python Interpretersnull1null`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

@tolusha How did you manage to install the python debugger ?

[tolusha]

@Leletir
yes, have you tried? https://marketplace.visualstudio.com/items?itemName=ms-python.python

[Leletir]

I'm using it on VS Code, so you've build Theia from source and added the plugins folder with this extension on it, isn't it ?
