2009-03-11contrib/difftool: use a separate config namespace for difftool commandsLibravatar David Aguilar3-23/+32
Some users have different mergetool and difftool settings, so teach difftool to read config vars from the difftool.* namespace. This allows having distinct configurations for the diff and merge scenarios. We don't want to force existing users to set new values for no reason so difftool falls back to existing mergetool config variables when the difftool equivalents are not defined.

2009-01-31contrib/difftool: Don't repeat merge tool candidatesLibravatar David Aguilar1-19/+12
git difftool listed some candidates for mergetools twice, depending on the environment. This slightly changes the behavior when both KDE_FULL_SESSION and GNOME_DESKTOP_SESSION_ID are set at the same time; in such a case meld is used in favor of kdiff3 (the old code favored kdiff3 in such a case), but it should not matter in practice.

2009-01-19contrib/difftool: remove distracting 'echo' in the SIGINT handlerLibravatar Markus Heidelberg1-1/+0
When interrupting git-difftool with Ctrl-C, the output of this echo command led to having the cursor at the beginning of the line below the shell prompt. Signed-off-by: Markus Heidelberg <markus.heidelberg@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-19contrib/difftool: change trap condition from SIGINT to INTLibravatar Markus Heidelberg1-1/+1
git-difftool worked for me on an up-to-date Gentoo Linux at home, but didn't work on a somewhat older Ubuntu Linux 7.10 at work and failed with the following error, where 'Makefile' was locally modified: trap: 244: SIGINT: bad trap external diff died, stopping at Makefile. In 'man 1p trap' there is written: "The condition can be EXIT, 0 (equivalent to EXIT), or a signal specified using a symbolic name, without the SIG prefix, [...]" "Implementations may permit names with the SIG prefix or ignore case in signal names as an extension." So now we do it the POSIX compliant way instead of using an extension. Signed-off-by: Markus Heidelberg <markus.heidelberg@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-18difftool: put the cursor on the editable file for VimLibravatar David Aguilar1-2/+6
You only need to edit worktree files when comparing against the worktree. Put the cursor automatically into its window for vimdiff and gvimdiff to avoid doing <C-w>l every time. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-18difftool: fix documentation problemsLibravatar David Aguilar2-13/+12
This patch makes the difftool docs always refer to the git-difftool script using the dashed form of the name. Only command examples use the non-dashed form now. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-17contrib: add 'git difftool' for launching common merge toolsLibravatar David Aguilar3-0/+418
'git difftool' is a git command that allows you to compare and edit files between revisions using common merge tools. 'git difftool' does what 'git mergetool' does but its use is for non-merge situations such as when preparing commits or comparing changes against the index. It uses the same configuration variables as 'git mergetool' and provides the same command-line interface as 'git diff'.
