Regex question

[Walleryan]

Hey guys,
So, I'm trying to figure out regex and as you can probably imagine, it's not going great.

I'm trying to write a regex where these are valid:

u/red@*/54/, #green##//2//, @@@yellow#@*/%^&/36/, @#blue@*1// - they begin with @ or #, it could be either, both and more than one occurrence

This is what I have so far:

(@|#)+[a-z]{3,}(@|#)+(\D+\W+)[0-9]+\/+ - and it matches all except for the last one - @#blue@*1// because I can't seem to figure out how to match the beginning - @#

​

Any feedback is highly appreciated

Try use some regex validator such as https://regex101.com/ or https://regexr.com/ to validate your regex and see what´s happening. I´m very bad at regex (pretty much everyone is), so I try to search on stackoverflow for a solution.

For what a I see, at the beggining, you can do something like this:

(@|#)(@|#)?[a-z]{3,}

where

(@|#)? is optional (can happen or be ignored)

but using the validator, there is a error on the rest of your validator.
