Today: Fun with Unicode, Regex and Java.

03-Nov-09

Some would say, i have 3 problems ;) 

private final static Pattern placeholder = Pattern.compile("#\\{(\\w+?)\\}");

won’t match “Mot#{ö}rhead” for example.

To replace the word character \w you either need the list of possible unicodeblocks like [\p{InLatin}|\p{InEtc}] (you get the codes for the blocks through “Character.UnicodeBlock.forName” or you’re lazy like me and just use the dot:

private final static Pattern placeholder = Pattern.compile("#\\{(.+?)\\}");

Oh what a day… :/

How to change the image assets path in Rails

01-Nov-09

I found no other way to change the path of “images” in a Rails application than monkey patching the AssetTagHelper like so:

module ActionView
  module Helpers #:nodoc:
    module AssetTagHelper
      def image_path(source)
        compute_public_path(source, 'static_images')
      end
      alias_method :path_to_image, :image_path # aliased to avoid conflicts with an image_path named route
    end
  end
end
