Regex flavor

[Giray]

I need to write a super simple regex. I was going to post the ask on Reddit but they ask what flavor of Regex we're using: PCRE, Python, Javascript, Notepad++, Sublime, Google Sheets, etc

Thanks

in case anyone wants to try their hand, it's just:

• Any uppercase letters (no limit on # of characters) followed by exactly 4 digits
• No digits allowed before the the letters
• No letters allowed after the four digits
• No special characters allowed

So good:

• JOHN1960
• JEFF5120
• JIM2345

But bad:

• 12JOHN1960
• JOHN 1960
• JOHN19607
• JOHN1960T

All I really need is the 'flavor'. No need to really rack your brains over the expression. Just posted in case we have a wiz who can bang it out in their sleep. Otherwise will post on the regex subreddit.

Thanks all.

PCRE flavor.

As for the regex itself, try this one:

/^[A-Z]+[0-9]{4}$/gm

My bad, put it in the wrong place.

@Terabyte thanks. Almost perfect. For some reason, the [A-Z] is still allowing for lowercase letters to slip through?

Also, in regex101.com I can't seem to put the first / and the /gm. It asks for a \ escape. But without it works fine, I just have to force the uppercase 😉

DUH. Figured it out. Fantastic, works!! Thank you.
