support vscode scm api

[akosyakov]

APIs: https://code.visualstudio.com/api/references/vscode-api#scm

There is VS Code extension for Git: https://github.com/Microsoft/vscode/tree/master/extensions/git

Our SCM UI is bound to Git right now. We need to extract Git-agnostic UI to a new extension. This extension should provide APIs similar to VS Code. Git extension has to be updated to use this API. The plugin extension then should use new API to implement VS Code SCM API.

Hi, is it expected to be in progress in the nearest time? We need it to launch VsCode pull request plugin: https://marketplace.visualstudio.com/items?itemName=GitHub.vscode-pull-request-github

If not we can take it, @akosyakov @svenefftinge WDYT?

[vinokurig]

The deadline for our related task (eclipse-che/che#11867) is 5-th February

Nice, please go ahead if you can start working on it now. :)

Hi I am wondering if it is possible / good strategy to reuse vscode git extension and completely replace the current theia git implementation. WDYT ?

[vinokurig]

@sunix As far as I understood this issue is about supporting scm Plugin-Api. I think it is better to discuss such questions in #3815 or #3956

Eventually, maybe, if there won't be any clients. Before it the current git extension and git VS Code extension should share the same UI and contribution points.

[vinokurig]

I guess it depends on #3423

[akosyakov]

@vinokurig It is another way around.

May be I missed something but as far as I understood this issue is about implementing vscode scm api but Theia doesn't have Source Code Management. Am I right?

[vinokurig]

Git extension has to be updated to use this API. The plugin extension then should use new API to implement VS Code SCM API.

@akosyakov Do you mean that Vscode scm api should use existed Git extension?

[vinokurig]

@akosyakov Could you please explain how this issue is related to VSCode Git extension?

[vinokurig]

Vscode uses Scm Service for this Api: https://github.com/Microsoft/vscode/blob/master/src/vs/workbench/services/scm/common/scmService.ts#L128,
Do we need such service?
