Regexper: Beautiful regexp visualizations

Re: Regexper: Beautiful regexp visualizations
#12Neither beautiful nor a visualization really. For the uninitiated, there's an isomorphic relationship between regular expressions (not PCREs which are way more complicated) and finite state automata proving that if you have a regexp you can generate a FSA for it, and visa versa. What we have here is a system that generates a graph of the finite state automaton for any given regular expression. Neat project, misleadin…
The path idea is a great one! If the original dev doesn't add that I may be tempted to try building my own regex tool with these features.

#13The following valid js regexp gives a server error:
^/([^/]+)[/]?(_((site)?(edit|show|manager))(/|$))?([\s\S]*)

#14Nice, but would be nicer if it had a couple of samples to show what the site can do for you.

You need to remove the slashes from that example
Re: Regexper: Beautiful regexp visualizations
#17but it doesn't show what is matched - as in a example matched string - which is the most important thing
also how do you put in the case insensitive flag?

I disagree. It could look better, but I fail to see how a graph is not a visualization (?)
Quite useful to show junior devs who are usually afraid of RegExp. Example from jQuery/Sizzle's: http://cl.ly/image/321F0E2B222o (^ and $ removed since it's failing to parse)
Re: Regexper: Beautiful regexp visualizations
#19Be nice to be able to include the regex in the url so I could link it in documentation or have some sort of rest interface.
Re: Regexper: Beautiful regexp visualizations
#20looks neat. can you please make the regex textbox use a fixed width font, reading a regex is already hard enough, let alone when it is in Verdana
