* fix: git-log produces no output
2006-04-21git-log produces no outputLibravatar Linus Torvalds1-0/+2
When $PAGER is set to 'less -i', we used to fail because we assumed the $PAGER is a command and simply exec'ed it. Try exec first, and then run it through shell if it fails. This allows even funkier PAGERs like these ;-): PAGER='sed -e "s/^/`date`: /" | more' PAGER='contrib/colordiff.perl | less -RS' Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-16Do not fork PAGER=catLibravatar Junio C Hamano1-1/+1
Unless the user has a nonstandard "cat" command that does not meow like a cat, this should not break anything and would save an extra pipe. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-04-16pager: do not fork a pager if PAGER is set to empty.Libravatar Johannes Schindelin1-7/+10
This skips an extra pipe, and helps debugging tremendously. [jc: PAGER=cat is a questionable hack and should be done as a separate patch. ] Signed-off-by: Johannes Schindelin <Johannes.Schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-02-28Introduce trivial new pager.c helper infrastructureLibravatar Linus Torvalds1-0/+48
This introduces the new function void setup_pager(void); to set up output to be written through a pager applocation. All in preparation for doing the simple scripts in C. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
