* difftool: Allow specifying unconfigured commands with --extcmdDavid Aguilar2010-01-091-7/+23
| | | | | | | | | | | git-difftool requires difftool.<tool>.cmd configuration even when tools use the standard "$diffcmd $from $to" form. This teaches git-difftool to run these tools in lieu of configuration by allowing the command to be specified on the command line.

* difftool--helper: Remove use of the GIT_MERGE_TOOL variableDavid Aguilar2010-01-091-5/+4
| | | | | | | | | | | | | An undocumented mis-feature in git-difftool is that it allows you to specify a default difftool by setting GIT_MERGE_TOOL. This behavior was never documented and was included as an oversight back when git-difftool was maintained outside of git. git-mergetool never honored GIT_MERGE_TOOL so neither should git-difftool.

* difftool--helper: Update copyright and remove distracting commentsDavid Aguilar2010-01-091-4/+1
| | | | | | | | Some of the comments in git-difftool--helper are not needed because the code is sufficiently readable without them. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* mergetool--lib: simplify API usage by removing more global variablesDavid Aguilar2009-04-121-3/+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.

* difftool/mergetool: refactor commands to use git-mergetool--libDavid Aguilar2009-04-081-177/+9
| | | | | | | | This consolidates the common functionality from git-mergetool and git-difftool--helper into a single git-mergetool--lib scriptlet. Signed-off-by: David Aguilar <davvid@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* difftool: add support for a difftool.prompt config variableDavid Aguilar2009-04-071-2/+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>
* difftool: move 'git-difftool' out of contribDavid Aguilar2009-04-071-0/+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>
