Feature #21552
closed
allow String.strip and similar to take a parameter similar to String.delete
Description
Regrading String.strip (and lstrip, rstrip, and ! versions)
Some text data representations differentiate between what one might call vertical and horizontal white space, and the 'strip' methods currently strip both.
It would be helpful if they had an optional parameter similar to String.delete with a one multi-character selector, so one could do:
t = str.strip " \t"
One can use a regex for this, but this much simpler.

Agreed. I tend to use str.sub(/[\ \t]+\z/,'') for this, but an end-anchored regexp has pretty bad worst-case performance. Try to benchmark the previous when str = " "*1000+"a" 😦

I just heard someone ask for a strip function that doesn't remove NUL characters.
Since Python's str.strip takes an optional argument, it might be a good idea to introduce a similar feature.
