Need an elegant way to solve a simple problem

I have a ByteString line. I want to strip blanks and tabs at end of it. Blanks and tabs allowed between words. MxMatcher looks a bit like using a gun to kill a fly. Any suggestion about a time effective way of solving the problem? (obvious way: asOrderedCollection and then backtrack killing spaces & tabs until find non space/tab char).

Best regards,

CdAB

You can use #withBlanksTrimmed (and #withoutLineEndings) for that.

Best,

If stripping leading blanks is okay, then you can use #withBlanksTrimmed.
Otherwise you can use the following oneliner:

string copyFrom: 1 to: (string lastIndexOfAnyOf: CharacterSet nonSeparators startingAt: string size ifAbsent: string size)

Thnx Levente & Marcel. Problem solved with #withBlanksTrimmed.
