http://snippets.dzone.com/posts Fri, 29 Aug 2008 12:13:34 GMT DZone Snippets: strings code http://snippets.dzone.com/posts/show/557 This code was inspired by Peter's code from May 17... <br /> <br />I basically extended his idea to be more flexible and added ! methods to modify the string in place. I chose to use a different regex selector because using "\b" breaks on apostrophes and leave you with words like "You'Re" instead of "You're"... <br /> <br /><code> <br /> <br />class String <br /> <br /> def titlecase() <br /> ignore_list = %w{of etc and by the for on is at to but nor or a via} <br /> capitalize_all_ex(ignore_list) <br /> end <br /> <br /> def titlecase!() <br /> ignore_list = %w{of etc and by the for on is at to but nor or a via} <br /> capitalize_all_ex!(ignore_list) <br /> end <br /> <br /> def capitalize_all(force_downcase = true) <br /> ignore_list = %w{} <br /> capitalize_all_ex(ignore_list, force_downcase) <br /> end <br /> <br /> def capitalize_all!(force_downcase = true) <br /> ignore_list = %w{} <br /> capitalize_all_ex!(ignore_list, force_downcase) <br /> end <br /> <br /> def capitalize_all_ex(ignore_list, force_downcase = true) <br /> # if force_downcase is true then the <br /> # string is, um, downcased first :-) <br /> if force_downcase <br /> self.downcase.gsub(/[\w\']+/){ |w| <br /> ignore_list.include?(w) ? w : w.capitalize <br /> } <br /> else <br /> self.gsub(/[\w\']+/){ |w| <br /> ignore_list.include?(w) ? w : w.capitalize <br /> } <br /> end <br /> end <br /> <br /> def capitalize_all_ex!(ignore_list, force_downcase = true) <br /> if force_downcase <br /> self.replace(self.downcase.gsub(/[\w\']+/){ |w| <br /> ignore_list.include?(w) ? w : w.capitalize <br /> }) <br /> else <br /> self.replace(self.gsub(/[\w\']+/){ |w| <br /> ignore_list.include?(w) ? w : w.capitalize <br /> }) <br /> end <br /> end <br />end <br /></code> <br /> Sat, 06 Aug 2005 00:09:31 GMT http://snippets.dzone.com/posts/show/557 s0nspark (Tim Ferrell)
