smarter character replacement using ruby gsub and regexp
- by agriciuc
Hi guys!
I'm trying to create permalink like behavior for some article titles and i don't want to add a new db field for permalink. So i decided to write a helper that will convert my article title from:
"O "focoasa" a pornit cruciada, împotriva barbatilor zgârciti" to
"o-focoasa-a-pornit-cruciada-impotriva-barbatilor-zgarciti".
While i figured out how to replace spaces with hyphens and remove other special characters (other than -) using:
title.gsub(/\s/, "-").gsub(/[^\w-]/, '').downcase
I am wondering if there is any other way to replace a character with a specific other character from only one .gsub method call, so I won't have to chain title.gsub("a", "a") methods for all the UTF-8 special characters of my localization.
I was thinking of building a hash with all the special characters and their counterparts but I haven't figured out yet how to use variables with regexps.
What I was looking for is something like:
title.gsub(/\s/, "-").gsub(*replace character goes here*).gsub(/[^\w-]/, '').downcase
Thanks!
