'This is a string.' trimRight: [ :c | c = $. ] works fine for me. The trimRight method will return a new string object without the punctuation. If you just do the expression without assigning it into a variable/method call, then it will have no effect because strings are immutable so the original string will remain unchanged. ------------ | myString trimmedString | myString := 'This is a string.' . trimmedString := 'This is a string.' trimRight: [ :c | c = $. ]. 1 assert: (trimmedString last = $.) not; assert: myString ~~ trimmedString; assert: myString last = $.
----------- Other trim options: 'This is a string.' allButLast. 'This is a string.' reject: [ :c | c =$. ]. 'This is a string.' copyReplaceAll: '.' with: ''. '' join: ($. split: 'This is a string.' ). 'This is a string.' onlyLetters. 'This is a string.' withoutPeriodSuffix.

I want to trim the trailing period off of the string. I've tried using: 'This is a string.' trimRight: [ :ea | ea = $. ] But, the period is not trimmed. Is there a way to do this without me having to extend the String class? ----- Brad Selfridge -- View this message in context: http://forum.world.st/trimRight-problem-tp4915603.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
