I think it is quite good idea, but it covers only one of the three most common (I think) used versions of git-commit: * git commit <files> # your proposal covers this * git commit -a # but I think either this * git commit # or this is actually more common Also "git commit ." in a submodule cannot be done in this proposal, because it is indistinguishable from "git commit <submodule>" committing state of submodule in supermodule. Perhaps it would be matter of porting "--relative=<path>" or adding "--submodule=<name>" option to git-commit? > However, pushing is a separate issue entirely.

I think there should be two easy to obtain variants of recursive clone: 1. Current one, where each submodule gets its own repository in the place it is checked out in working area (in worktree) of supermodule. 2. New one, where submodule repositories are in .git/submodules/<name> in supermodule GIT_DIR, and submodules use gitfiles (probably with some notation that path is relative to supermodule, like e.g. //<path> or .../<path>). I'm not sure though how it would translate into pushing... -- Jakub Narebski Poland -- 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
