Comment 1 Magnus Glantz 2010-11-20 14:08:53 EST
Reason of setting LESS_IS_MORE was at least some years ago to be able to exit a man page without clearing the screen, keeping what was displayed on the screen when issuing 'q'. This actually still works when setting the variable, but, the man-page's formating so bad that it's useless.

The problem is fixed in man-db-2.5.9-2.fc15.

Comment 7 Pádraig Brady 2010-11-26 07:54:47 EST
I use vim to browse my man pages and also noticed this new messed up format. But I was able to work around it by setting: export GROFF_NO_SGR=1 I see you hardcoded the addition of the -c option to nroff. That means that if you do want SGR codes shown, you can't. I.E. with the above change, one can no longer use the following command to dump a man page with highlights: MANPAGER=cat man man Would it perhaps have been better to auto set GROFF_NO_SGR in the logic dealing with LESS_IS_MORE?
Comment 8 Pádraig Brady 2010-11-26 07:55:51 EST
BTW it would be nice to link the changes made from the bug reports: http://pkgs.fedoraproject.org/gitweb/?p=man-db.git;a=commitdiff;h=e8aabf03 Cheers.
Comment 9 Pádraig Brady 2010-11-29 08:17:52 EST
Some more notes for reference: on ubuntu 10.04 with groff-base 1.20.1-7 The following does _not_ show highlights (SGR codes) printf '.TH header\n.SH highlight\n' | nroff -mandoc while on fedora 14 + groff-1.20.1-2.fc14.i686 the above _does_ show SGR codes unless GROFF_NO_SGR is set The nroff commands run by both ubuntu and fedora are the same I think, apart from this new -c option in fedora added in the above patch.
Comment 10 Peter Schiffer 2013-04-29 11:59:01 EDT
Guys, I just wanted to let you know that I'm going to drop the patch used to fix this bug. As Pádraig mentioned, now it's impossible to show SGR codes when desired. Magnus, if you want to use LESS_IS_MORE variable, please use also GROFF_NO_SGR. Thanks, peter
