From 2d10c555374df257e32848ba6f77fd73d608645f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 20 Sep 2006 13:21:56 -0700 Subject: [PATCH] git log: Unify header_filter and message_filter into one. Now we can tell the built-in grep to grep only in head or in body, use that to update --author, --committer, and --grep. Unfortunately, to make --and, --not and other grep boolean expressions useful, as in: # Things written by Junio committed and by Linus and log # does not talk about diff. git log --author=Junio --and --committer=Linus \ --grep-not --grep=diff we will need to do another round of built-in grep core enhancement, because grep boolean expressions are designed to work on one line at a time.
