Metadata completion is canceled on ":"

[Simn]

Is this something we can fix or are we gonna need MS support?

No idea, need to find out why it happens in the first place..

Opened an issue on the vscode repo: microsoft/vscode#12772

Ok, got an answer. This works:

var defaultWordPattern = "(-?\\d*\\.\\d\\w*)|([^\\`\\~\\!\\@\\#\\%\\^\\&\\*\\(\\)\\-\\=\\+\\[\\{\\]\\}\\\\\\|\\;\\:\\'\\\"\\,\\.\\<\\>\\/\\?\\s]+)";
var wordPattern = defaultWordPattern + "|(@:\\w*)"; // metadata
languages.setLanguageConfiguration("haxe", {wordPattern: new js.RegExp(wordPattern)});

...except that completion is still canceled on : because we have that as a trigger character (type hints) - not sure if we can do anything about that. :/

To me, the triggerCharacters docs suggest that there might be a way to trigger completion manually (as they explicitly say "automatically"):

The characters that trigger completion automatically.

Does it also cancel if we reject in onCompletion?

[Gama11]

Looks like it. Also, even if that worked, it'd seem a bit hacky, since you have to reject it with some error message which is then printed to the output.

The flickering when the completion list is closed and reopened is frankly a bit annoying, but I guess we can (have to?) live with that.
