Detect and scan WSL roots and other remotes

See #2
As of now, WSL2 does not provide any reliable way to retrieve home directories and even if we add them manually, traversal is really slow from Windows.

I made a few tests on WSL : if the repo binary is not found on host side (I explicitly moved it during the test) and I have a repo in PATH in WSL filesystem, then everything works fine

vscode-repo/src/executor.ts

Lines 37 to 44 in b975052

	const bundled = vscode.Uri.joinPath(
	context.extensionUri,
	'bin',
	`${executableName}${process.platform === 'win32' ? '.exe' : ''}`
	)
	if (await fileExits(bundled)) return bundled.fsPath
	if (await isInPath(executableName)) return executableName

It only shows WSL repositories, but that's what I expect as a WSL vscode user :

• vscode on host shows host repos
• vscode on remote WSL shows WSL repos

Hope it helps :)

That totally makes sense. I think, we should prefer repo in PATH over bundled one. That way, it can be used in both environments. What about —

• exposing a setting to use binary from PATH and using bundled binary as fallback. That should make it at least compatible with WSL for people having repo in PATH.
• adding ability to edit repo config within VSCode.

On the other hand, combining these two automatically is still a problem which I think we should not solve because these two are different environments and filesystems with very minimal APIs support. Even if I implement that, it will be slow and buggy. The primary reason I created repo and this extension was speed.

Yep, looks good to me !
I'm also in favor to not combine host & WSL repositories; as I said I'm fine with only having the repositories from where (host/wsl) vscode has been launched.

An improvement for later on the WSL flow could be to have a vscode command to download the repo unix binary to a known location so we won't have to download it our-self or set the PATH.

I've just published v0.4.0 which includes —

• repositories.preferBundled config, which will look binary in the PATH first when set to false.
• repositories.showInStatusBar config, which will allows to you to control visibility of current repo in status bar.
• Repositories: List Repos command which allow you to search and select repos to jump.
• Repositories: Edit configuration command as well as a settings icon in repository view, which allows you to edit current config.
