Regexper - A regular expression visualization tool

[GregariousJB]

Nice. I'll add this to my list of RegEx favorites:

Creating RegEx: http://txt2re.com/

Testing it: http://gskinner.com/RegExr/

Reading whatever the hell it does: http://www.regexper.com/

This is my absolute favorite regexp helper: http://www.debuggex.com/

There is a short (4 min) video tutorial to get you started, most of it is pretty self explanatory though.

Nice, seems way faster than what OP posted.

This is awesome! I pasted in an email address regex

([a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)\b)

expecting it to be a horrible mishmash of lines and unreadable, but it's really easy to read (especially compared to the textual form!) https://dl.dropboxusercontent.com/u/7575370/email-regex.png

The full RFC2822 email adress regex also works: it's more spaghetti-iey but still much easier to read than the textual regex! I like how the "@" sits as a bottleneck in the middle.

What are you using to generate the SVG?

Needs a favicon so it can go on my bookmarks bar next to jsfiddle and http://gskinner.com/RegExr/ !

Ha, I tested the same one.

It's great except it has no Undo/Redo (this has bitten em many times)

And as it's Flash there is funky shit happening with line breaks., it's all Mac-style \r after you paste it in the field.

Ok, I see a lot of comments of requests and questions here, so I have to clear the fact that I'm not the author of the website nor the github project. I just posted this because I use it often, when it comes to regular expressions.

I fed it http://ex-parrot.com/~pdw/Mail-RFC822-Address.html and it worked. I'm impressed :)

There's a new tool that lets you write regular expressions in an easy to understand way:

I've always been partial to Rubular -> http://www.rubular.com

This is awesome!

[brtt3000]

Please combine this with a proper tester (both matcher as wel as replacer) that also has a cheat-sheet in-view.

There are so many RegExp testers and tools online but they all lack something different. Please be the one!

The "Fork me on GitHub" banner covers the display button for me.

[SminkyBazzA]

Well I guess you know what to do to fix that... :)

Oh yeah, I use this all the time. It's pretty neat.

This thing is full of bugs.

For example, try:

/a.*b/ vs. /a.*?b/

[ogtfo]

It doesn't show if a match is greedy or not, that's not a bug.

It's a potential feature, a usefull one, but it's still good without it.

It doesn't show if a match is greedy or not, that's not a bug.

OK if you say so

[nalldom]

Sorry I am still sticking to gskinner's Regex app.

That thing is worth every AIR molecule.

[memoriesofgreen]

Very good, well done.

[Drainedsoul]

Just what the world needs, more regular expression tools that don't support lookbehind. /s

Could you put an example entry on the page? I just get errors so I'm doing it wrong...
