Im looking for a way to parse regex using variables so i can dump the regex in question (substitutions) to a config file so it can be user editable, now i've tried simply using varaibles and found that although it does work i have to process the regex data before hard or force the user to write ridiculusly convoluted regex strings (as opposed to just convoluted :D), anyway in short what id like to know is if theres a better way of doing things, perhaps something i've missed or a module just for the task ?
