Greetings, All!
It was bugging me for quite some time now. I don't like POSIX RE - they are
cumbersome and unwieldy.
Is there a possibility to build man for Cygwin with PerlRE support?

Presumably that would come via PCRE, which man-db does not currently
support. Perhaps PTC upstream.

If there were such a mode, would it be allowed to enable it, since that would effectively put libpcre into Base?

grep already requires libpcre1.

All my Linux boxes recognize PerlRE in man. >.<
Given, they are all Debian based... And most of them are Ubuntu. I don't know
how it is widespread.

I’m curious: what sort of incantations do you frequently give to man which involve REs?
Maybe I’m just too old-school, but I wasn’t aware that modern man programs even supported REs. Back when I was a boy, we said “man -k whatsit” and we liked it! :)
I think if I wanted to grep man pages with Perl syntax, I’d say
grep -PRsl whatsit /usr/share/man
Poking around on machines near me, I see Lucifredi’s version of man — which doesn’t seem to support regexes — on OS X 10.10, FreeBSD 10.1, and CentOS 5. Apparently RHEL moved to man-db in EL6 or EL7, since it’s on an EL7 box nearby.

Typical ones. F.e.

to quickly find term references.

Maybe someone can rebuild less(1) to build with PCRE, and then you can set MANPAGER=less.

I don’t think Andrey means PCRE when searching the man page he is reading right now. I think he means he wants PCRE support in “man --regex whatsit”.

But I did mean exactly that.
Sorry, probably I should have been clearer. And, well, think my question more
thoroughly.
It seems like Mike's right, and the actual culprit is "less", rather than man.
