Regular expression tool

A webapp to test, match, exec and replace with regular expressions on strings

Inspired by the great tool of Grant Skinner: RegExr (Flash online tool)

It's use JavaScript's regular expression (supported by the browser)

• Regular Expression Syntax, Regular Expression Object and RegExp Object at the MSDN
• Regular Expressions Chapter and RegExp Object Referenc at the MDN
• ECMA-262, ECMAScript Language Specification
• http://docs.webplatform.org/wiki/concepts/programming/javascript/regex

Future improvements

• [critical] implements save/restore selection in #text. See _updateHighlights() and http://stackoverflow.com/a/5596688/470117
• enhance user interface!
• implements in #text and #output a HTML renderer of RAW text (\t\n\r) (or using the <pre> wrapper trick). It's a Firefox bug
• implements a RegExp parser like RegExr + predefined and community patterns (use datalist?)
• check if ReplacePatternSlicer handle correctly escaped chars (specially unknowns or marlformed escaped chars like \10 \z \x2 etc.)
• replace ReplacePatternSlicer by string.replacer(regexp, replacerFunction)?
• add support of XRegExp as an option (native or XRegExp)
• add timers for grouping input and change multiple frame events
• add process timing to: detect a potential bug (there are infinites loops here) or a heavy task could required be in worker (larges texts or lot of matches)
