Visualization of Regular Expression Character Classes
We all know the regular expression character classes, right? There are 12 standard classes: [:alnum:] [:digit:] [:punct:] [:alpha:] [:graph:] [:space:] [:blank:] [:lower:] [:upper:] [:cntrl:] [:print:] [:xdigit:] But have you seen a visual representation of what these classes match? Probably not. Therefore I created a visualization that illustrates which part of the ASCII set each character class matches. » Peteris Krumins | catonmat.net
