Support virtual workspaces

[lszomoru]

👋 Hi there, Martin here, from the VS Code team.

Recently we've announced the Remote Repository feature that lets you browse and edit files and folders directly on GitHub.

Open Remote Repository... opens VSCode on a folder or workspace located on a virtual file system. We call this a virtual workspace. We observed that not all extension support this well, either because they can not, or they haven't thought about it.

It would be fantastic if you could test whether your extension can handle virtual workspaces:

Check out the Virtual Workspaces Extension Author Guide on how to do that.

When done, set the new virtualWorkspaces capability in your 'package.json'.

{
  "capabilities": {
    "virtualWorkspaces": true | false
  }
}

• Use "virtualWorkspaces": true if your extension is prepared for virtual workspaces
• Use "virtualWorkspaces": false if your extension should be disabled when a virtual workspace is opened

For questions and comments please use the Virtual Workspaces Tracking Issue.

Thanks for the support and the great work! ❤️

@lszomoru Thanks for the heads up. In virtual workspace mode, files are not physically on disk. This extension depends on the go command in many ways (for file parsing, build/debug/test) and I think making the go command working with a virtual workspace is a major task if not infeasible. So, adding "virtualWorkspaces": false in our capabilities list for now seems to be right for this extension.

Change https://golang.org/cl/320430 mentions this issue: package.json: set virtualWorkspaces capability to false

Thanks for adopting the virtualWorkspaces capability!

It's now also possible to give a description why the capability is enabled or disabled:

{
  "capabilities": {
    "virtualWorkspaces": {
      "supported": false,
      "description": "Debugging is not possible in virtual workspaces."
    }
  }
}

{
  "capabilities": {
    "virtualWorkspaces": {
      "supported": "limited",
      "description": "In virtual workspaces, resolving and finding references across files is not supported."
    }
  }
}

This message can be seen in the extensions view:

Let's add description. Reopening.
