Yes it is the "current in next" behaviour, and no that is not what you should expect, and that is why I earlier said it is a mistake. The ability to choose which part to leave out of the working tree should not change the fact that git is about managing the history of the whole tree, not an individual file nor a subset of files. I do not think it is unreasonable to have a mechanism to let the user limit the area of the whole tree often used Porcelain commands look at. We already have pathspec "git grep -e foo kdeutils/" mechanism that lets you do such limiting. It is conceivable that some workflows _might_ find having the default pathspec convenient in end-user initiated operations, but then it would be convenient whether the end-user uses the sparse checkout to limit the area to kdeutils/ or has the whole checkout. Although I think it would be Okay to default the default pathspec match the checkout area when the sparse checkout feature is in use, I think the "checkout area" and "area of interest" should be two independent concepts. I said "_might_" in the above because I do not think it is such a good idea to have _the_ default pathspec to begin with, though. It would probably be more useful to allow people to use shorthands to pathspecs, and at that point you can use usual shell variables to do that already, e.g. instead of having to say "git grep -e foo arch/x86 include/asm-i386", you would say "git grep -e foo $i386", after "i386=arch/x86 include/asm-i386", or something like that. -- 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
