Subject: [PATCH 0/7] submodule groups
Message-ID: <1462928397-1708-1-git-send-email-sbeller@google.com>

I started from scratch as I think there were some sharp edges in the design.
My thinking shifted from "submodule groups" towards "actually it's just an
enhanced pathspec, called submodulespec".

The meat is found in the last 3 patches.

What is this series about?
==========================

If you have lots of submodules, you probably don't need all of them at once,
but you have functional units. Some submodules are absolutely required,
some are optional and only for very specific purposes.

This patch series adds labels to submodules in the .gitmodules file.

So you could have a .gitmodules file such as:

[submodule "gcc"]
        path = gcc
        url = git://...
        label = default
        label = devel
[submodule "linux"]
        path = linux
        url = git://...
        label = default
[submodule "nethack"]
        path = nethack
        url = git://...
        label = optional
        label = games

and by this series you can work on an arbitrary group of these submodules
composed by the labels, names or paths of the submodules.

    git clone --init-submodule=\*<label> --init-submodule=:<name> git://...
    # will clone the superproject checkout
    # any submodule being labeled <label> or named <name>

    git submodule add --label <name> git://... ..
    # record a label while adding a submodule

    git submodule update [--init] \*label2
    # update only the submodules labeled "label2"
    
    git config submodule.updateGroups default
    git config --add submodule.updateGroups devel
    # configure which submodules you are interested in....
    git submodule update [--init-default-group] 
    # ... and update them    

    git status 
    git diff
    git submodule summary
    # unlike the last series, these are not touched
    
    git submodule status \*label2
    # only show information about "label2" submodules.
    

Any feedback welcome, specially on the design level!

Thanks,
Stefan
