Invalid preceding regular expression regex pattern

[Broick]

Tried adding several regex patterns like (?=.[a-z])(?=.[A-Z])(?=.[0-9])(?=.[!@\$%\^&\*])(?=.{8,})
(?=.\d)(?=.[a-z])(?=.[A-Z])(?=.[@$%&*]).{8,} etc but getting fatal error
Found that issue is caused when used ? after (
Can someone help?

I don't maintain this project, but I have worked with it quite a lot.

Both git_grep() and regular_grep() functions in git-secrets script pass the -E flag to use "extended regular expressions". It looks like ERE doesn't support lookaround (what you're referring to as "preceding regular expressions". Have a look at this table (you can pick regex flavors by dropdown) to see for yourself. https://www.regular-expressions.info/refadv.html
