2009-04-12mergetool--lib: simplify API usage by removing more global variablesLibravatar David Aguilar1-3/+3
The mergetool--lib scriplet was tricky to use because it relied upon the existance of several global shell variables. This removes more global variables so that things are simpler for callers. A side effect is that some variables are recomputed each time run_merge_tool() is called, but the overhead for recomputing them is justified by the simpler implementation.

2009-04-07difftool: add support for a difftool.prompt config variableLibravatar David Aguilar1-2/+8
difftool now supports difftool.prompt so that users do not have to pass --no-prompt or hit enter each time a diff tool is launched. The --prompt flag overrides the configuration variable. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-04-07difftool: move 'git-difftool' out of contribLibravatar David Aguilar1-0/+221
This prepares 'git-difftool' and its documentation for mainstream use. 'git-difftool-helper' became 'git-difftool--helper' since users should not use it directly. 'git-difftool' was added to the list of commands as an ancillaryinterrogator. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
