ClearAll["Global`*"] stops working with Context set to 'unique to this Notebook'

Question

I just changed my default notebook context to 'unique to this Notebook' so that variables don't roll across numerous open notebooks. Doing this, however, made the command ClearAll["Global*"] stop working to clear all declared variables. I also tried, ClearAll[Evaluate[Context[] <> "*"]], but that didn't work either. Any ideas?

As soon as you set your notebook context to 'unique to this Notebook', the notebook's context is no longer Global`, but, well, unique to the notebook.

I can't test right now, but assuming you are not in an explicitly opened context (like after Begin or BeginPackage), I think the following should work:

ClearAll@@{$Context<>"*"}

At least it works in a kernel with manually changed $Context.

It works, so +1. – rcollyer May 30 '13 at 19:02
Awesome, totally works! Any ideas why variables aren't going back to blue (from black)? – DilithiumMatrix May 30 '13 at 19:38
@zhermes: I have no idea. IIRC the variables actually already start out being black when the notebook uses its own context (can't check now); no idea why. Maybe the colouring algorithm doesn't take the different context into account correctly. – celtschk May 30 '13 at 19:47

I think you could just do ClearAll@"`*"... – rm -rf May 31 '13 at 03:21

I think instead of ClearAll["Global`*"], you can just Clear["`*"]. This should work.
