It is something we thought would be helpful in the past: http://thread.gmane.org/gmane.comp.version-control.git/114269/focus=114367 On 2009-03-23 Junio C Hamano <gitster <at> pobox.com> wrote: > Perhaps we would want a convenient way for "log -p" or "show -p" to drive > difftool as a backend? I think that's exactly it. difftool wraps diff; a log equivalent would be quite helpful. One idea is for difftool to learn a "--log" option to make it wrap log instead. I don't know if a diff-like command having a "--log" option is ideal from a consistency-of-user-interface POV so I'm open to ideas. It is convenient, though. It does seem like difftool would be a good place to expose this feature. I'd be interested in the "teach log / show -p about GIT_EXTERNAL_DIFF" route, if that sounds like a good idea. -- David -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
