I have a line such as:

#define BLAH 10

or

#include "BLAH.h"

and I'm going around in circles trying to just get the 'include' or
'define' bit...anyone can help me?

Thanks
Bob.

Not quite sure what you mean - could you show some example of using
this, and the expected output?

>> ["#define BLAH 10", '#include "BLAH.h"'].map {|s| s[/^#(\w+)/, 1]}
=> ["define", "include"]
