Hm, I think it is the correct approach because readers of diffcore are probably going to look at the source: it's not exactly an end-user manpage. I've not explained it as G king versus S kind in the diff-options documentation. Or are you just talking about the error message? That's simple: --pickaxe-regex is what triggers this off, and we've made it clear that it applies to both commands (-G implicitly; see doc). -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

It happens to be implemented in the same source file as pickaxe, but they do logically quite different things. -G does not even have a reason to pay attention to --pickaxe-regexp (it is "grep in the log -p"). I suspect that it might avoid unnecessary confusion to explain them as totally separate operations, and not labelling this error with "pickaxe regex". I dunno. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH] diffcore-pickaxe: make error messages more consistent
Currently, diffcore-pickaxe reports two distinct errors for the same user error: $ git log --pickaxe-regex -S'\1' fatal: invalid pickaxe regex: Invalid back reference $ git log -G'\1' # --pickaxe-regex is implied fatal: invalid log-grep regex: Invalid back reference Since the error has nothing to do with "log-grep", change the -G error message to match the -S error message.
