Johannes Sixt	bfdd9ffd2f	Windows: Make the pager work. Since we have neither fork() nor exec(), we have to spawn the pager and feed it with the program's output. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>	17 years ago
Johannes Schindelin	ef90d6d420	Provide git_config with a callback-data parameter git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

Junio C Hamano	61b80509e3	sending errors to stdout under $PAGER If you do this (and you are not an Emacs user who uses PAGER=cat in your shell buffer): $ git init Initialized empty Git repository in .git/ $ echo hello world >foo $ H=$(git hash-object -w foo) $ git tag -a foo-tag -m "Tags $H" $H $ echo $H 3b18e512dba79e4c8300dd08aeb37f8e728b8dad $ rm -f .git/objects/3b/18e5* $ git show foo-tag tag foo-tag Tagger: Junio C Hamano <gitster@pobox.com> Date: Sat Feb 16 10:43:23 2008 -0800 Tags 3b18e512dba79e4c8300dd08aeb37f8e728b8dad you do not get any indication of error. If you are careful, you would notice that no contents from the tagged object is displayed, but that is about it. If you run the "show" command without pager, however, you will see the error: $ git --no-pager show foo-tag tag foo-tag Tagger: Junio C Hamano <gitster@pobox.com> Date: Sat Feb 16 10:43:23 2008 -0800 Tags 3b18e512dba79e4c8300dd08aeb37f8e728b8dad error: Could not read object 3b18e512dba79e4c8300dd08aeb37f8e728b8dad Because we spawn the pager as the foreground process and feed its input via pipe from the real command, we cannot affect the exit status the shell sees from git command when the pager is in use (I think there is not much gain we can have by working it around, though). But at least it may make sense to show the error message to the user sitting in front of the pager. [jc: Edgar Toernig suggested a much nicer implementation than what I originally posted, which I took.] Signed-off-by: Junio C Hamano <gitster@pobox.com>	17 years ago
Jeff King	6e9af863ee	Support GIT_PAGER_IN_USE environment variable When deciding whether or not to turn on automatic color support, git_config_colorbool checks whether stdout is a tty. However, because we run a pager, if stdout is not a tty, we must check whether it is because we started the pager. This used to be done by checking the pager_in_use variable. This variable was set only when the git program being run started the pager; there was no way for an external program running git indicate that it had already started a pager. This patch allows a program to set GIT_PAGER_IN_USE to a true value to indicate that even though stdout is not a tty, it is because a pager is being used.

Junio C Hamano	cad3a2056d	pager: find out pager setting from configuration It was very unfortunate that we added core.pager setting to the configuration file; even when the underlying command does not care if there is no git repository is involved (think "git diff --no-index"), the user would now rightfully want the configuration setting to be honored, which means we would need to read the configuration file before we launch the pager. This is a minimum change in the sense that it restores the old behaviour of not even reading config in setup_git_directory(), but have the core.pager honored when we know it matters. Note that this does not cover "git -p --git-dir where command"; the -p option immediately trigger the pager settings before we even see --git-dir to learn where the configuration file is, so we will end up reading the configuration from the place where we would _normally_ find the git repository.

Brian Gernhardt	54adf3706c	Add core.pager config variable. This adds a configuration variable that performs the same function as, but is overridden by, GIT_PAGER.

Linus Torvalds	35ce862279	pager: Work around window resizing bug in 'less' If you resize the terminal while less is waiting for input, less will exit entirely without even showing the output. This is very noticeable if you do something like "git diff" on a big and cold-cache tree and git takes a few seconds to think, and then you resize the window while it's preparing. Boom. No output AT ALL. The way to reproduce the problem is to do some pager operation that takes a while in git, and resizing the window while git is thinking about the output. Try git diff --stat v2.6.12.. in the kernel tree to do something where it takes a while for git to start outputting information. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Junio C Hamano	96a035d1db	pager: default to LESS=FRS Recent change to paginate "git diff" by default is often irritating when you do not have any change (or very small change) in your working tree. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Johannes Schindelin	b75a82b754	Fix linking for not-so-clever linkers. On one of my systems, the linker is not intelligent enough to link with pager.o (in libgit.a) when only the variable pager_in_use is needed. The consequence is that the linker complains about an undefined variable. So, put the variable into environment.o, where it is linked always.

Junio C Hamano	85fb65ed6e	"git -p cmd" to page anywhere This allows you to say: git -p diff v2.6.16-rc5.. and the command pipes the output of any git command to your pager. [jc: this resurrects a month old RFC patch with improvement suggested by Linus to call it --paginate instead of --less.] Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Johannes Schindelin	cd112cef99	diff options: add --color This patch is a slightly adjusted version of Junio's patch: http://www.gelato.unsw.edu.au/archives/git/0604/19354.html However, instead of using a config variable, this patch makes it available as a diff option.

Linus Torvalds	34fd1c9ac5	git-log produces no output 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>	19 years ago
Junio C Hamano	caef71a535	Do not fork PAGER=cat 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>	19 years ago
Johannes Schindelin	402461aab1	pager: do not fork a pager if PAGER is set to empty. This skips an extra pipe, and helps debugging tremendously.
