The 'true' and 'false' values to merge.ff are carry-over from the days when it was a boolean, _not_ a tristate. If we were to make the UI more rational by making it clear that this is not a boolean, it is a good time for us to aim a bit higher than merely repeating the mistakes we made in the past due to historical accident. In other words, we could add a synonym for the "default" mode in addition to "--ff=true" (and for the "always merge" mode in addition to "--ff=false") that makes it clear that the value is _not_ a boolean [*1*]. If we were to go the "--ff=<value>" route, we have to add support for other ways to spell boolean 'true' (e.g. 'yes', '1', and 'on') anyway, so it is not that much extra work to do so, I would think. > Otherwise, this looks like a very nice way to implement what I want: I > guess it is probably a mistake that the existing (documented) flags do > not behave in this way? Yeah, right now if you say "merge --ff-only --no-ff", we say these are mutually exclusive (which is true), but if you think about the tristate nature of the 'ff' option and spell it differently in your head, i.e. "merge --ff=only --ff=never", it is reasonable to argue that we should apply the usual "last one overrides" rule and behave as if "merge --no-ff" were given (for the purpose of "last one overrides", the configured defaults can be treated as if they come very early on the command line). After all "merge --no-ff --ff" does seem to use the "last one overrides" rule. [Footnote] *1* Perhaps 'allowed' instead of 'normal' (which I wrote out of thin-air; I do not have any strong preference on the actual values) may be a better choice for such a "this is not a boolean" spelling for the default mode. -- 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
