Would be nice to have a regex for parsing HTML... grabs popcorn
With subroutines and recursive patterns I think you could do something parsing valid HTML.
Your sanity won't be left intact tho.

#42I don't understand why the Github repository lists regexper as the source of the visual graph code but the frame only shows iHateRegex as watermark?
If the only thing that is embedded in that frame was taken entirely from a different project, that project should at least be mentioned in the frame.

#43^[a-z0-9_-]{3,15}$ The username reference doesn't match 16 characters as claimed
I should match. the number 15 there means that repeat x up to 15 times. so 1+15=16. looks good to me
That is not correct. 15 is total maximum number of repeats including the first one. Even the diagram on https://ihateregex.io/expr/username correctly says that loop can be taken between 2 and 14 times.

#44neat site! clicking an example opens up a playground with live update and explanation and railroad diagrams, similar to sites like regex101[1] and regulex[2] one suggestion would be to mention clearly which tool/language is being used, regex has no unified standard.. based on "Cheatsheet adapted" message at the bottom, I think it is for JavaScript. I wrote a book on js regexp last year, and I have post for cheatsheet…
Totally agreed! Right now I only support javascript. But for everything shown there, it's pretty much the same for most flavors

#47Very cool! The site that worked best for me to learn regex was https://regexcrossword.com/ - after solving my way through all of them (I got really hooked when I discovered the site) I found I was alright at regex.

#48Nice tool!
I personally use https://regex101.com/ as I like the explanations and quick reference.

#49This is really cool! 2 points: 1. it fiddled with my back button which is a bit annoying 2. a better email sample is ^[^@]+@[^@]+\.[^@]+$ which removes the 2 ampersands problem.
That's not how the spec works. Compliant solution: https://stackoverflow.com/a/1917982
