Regular expression syntax packs a lot of power into terse notation, which makes it easy to forget whether a particular construct uses parentheses or brackets, or whether a quantifier is greedy by default. This page combines a comprehensive reference for regex syntax with a live testing area, so you can look up the syntax you need and immediately try it out. No more switching between documentation tabs and your testing tool.
