One of the things that I find I need to do every now and then is to have a case-insensitive<\/em> regex pattern match in clojure, and I always have to spend 15 mins looking for it on the net. Not that it's hard to find, but it's 15 mins, and if I know I wrote about it here, then I can do a much quicker search, and get the same answer.<\/p>\n The key is that the Java regex parser recognizes two interesting options to the source for the regex: (?i)<\/tt> and (?iu)<\/tt>. The first, (?i)<\/tt>, is the flag to indicate that the entire regex is to be considered case-insensitive. The second, (?iu)<\/tt> is for unicode support.<\/p>\n So how's it work?<\/p>\n It's simple and easy, and typically saves you from calling lcase<\/tt> on the string before the regex test.<\/p>\n","protected":false},"excerpt":{"rendered":" One of the things that I find I need to do every now and then is to have a case-insensitive regex pattern match in clojure, and I always have to spend 15 mins looking for it on the net.
