Hi ,
i hate to say but it was just an exhaustive whole week trying to convert nuclei regexes that are present in exposures/tokens templates ,
but all in vain , multiple errors .

What type of regular expressions are they ?
which regex engine nuclei uses ?

And most importantly i want to know : Which regex engines fully supports all the regexes that are in exposures templates ?
I tried to convert these regexes to be compatible with grep regex engine and PCRE engine , always an error comes stating certain operaters are not supported from regex ,

Kindly help me , this has become much exhausting task for me.

Regards,
