@felixfbecker thanks a lot for your contributions!
The changes look good. Now let's try to fix your build issues.
From pr #15174 and looking at your original errors they all seem to be related to the generated monaco editor api file. I think we can just ignore those and still be able to run out of source with \scripts\code.bat. More details https://github.com/Microsoft/vscode/wiki/How-to-Contribute

As for the monaco.d.ts errors, maybe try good old git clean -fxd, and again scripts\npm install and gulp watch. Basically the monaco.d.ts file gets generate from monaco.d.ts.recipe and for some reason on your machine he is looking for other definition files which I do also do not have.

If running out of source does not work with these errors let me know and I will ask around for a solution for your issue.

Another bug

@felixfbecker did you succeed in runnning vscode out of source?

Yes. I tested it, absolute paths work correct now. How can I get the node debugger in the OSS Dev build? Mocha always throws the relative paths, would like to test those

@felixfbecker awesome! To get the node debugger in the oss dev build install it from the gallery, to enable the gallery in the oss dev build first add the following to the product.json before building the oss dev vscode. Let me know how it looks and if it seems good I will merge it in

"extensionsGallery": {
	"serviceUrl": "https://marketplace.visualstudio.com/_apis/public/gallery",
	"cacheUrl": "https://vscode.blob.core.windows.net/gallery/index",
	"itemUrl": "https://marketplace.visualstudio.com/items"
}

@felixfbecker let me know how this is working once you test those mocha relative paths - thanks!

Just tested, works!

Side effect: the parens are underlined. No that much of a deal imo though

PHPUnit works:

Normal call stacks not unfortunately:

Awesome, let's merge this baby in.

@felixfbecker we can not handle each and every case. This should improve once we start using the editor intead of the tree. Might investigate into that over Christmas

Yeah I don't know how to handle it while still supporting spaces in paths (without matching the whole line by mistake).

I will come back to that offer 😄
