Selectively clone Git submodules -- a useful feature?

Selectively clone Git submodules -- a useful feature?

[Lars Schneider]

Hi,

AFAIK Git has two ways to clone a repository with respect to submodules:

(1) Plain clone of just the repository itself:
git clone git://github.com/foo/bar.git

(2) Recursive clone of the repository including all its submodules:
git clone --recursive git://github.com/foo/bar.git

I am working on a big cross platform project and on certain platforms I don't need certain submodules. AFAIK there is no way to selectively clone only a subset of the submodules with the standard command line interface. I wonder if something like an exclude pattern for submodules would be of general interest. I imagine a call like this after a plain "clone" operation:

git submodule update --init --recursive --exclude 3rdParty/Windows/*

or even:

git clone --recursive --exclude 3rdParty/Windows/* git://github.com/foo/bar.git

Please let me know what you think.


Thanks,
Lars

I am sorry, but I discovered this mailing list afterwards and I am not sure which one is the appropriate one. Please advise.

Git already supports that use case: Just set the "submodule.<name>.update"
configuration to "none" for all submodules you aren't interested in and
"git submodule update" will always skip them.

You can also set this config option globally:

git config --global submodule.<name>.update=none

That'll set the default for all repositories of the logged in user on this
computer to not update submodule <name>.

git clone will be influenced by the global setting. If you just want to
skip submodule <name> for a single clone you can do it like this:

   git -c submodule.<name>.update=none clone --recursive git://github.com/foo/bar.git

I am looking forward for exactly that feature, I even proposed exactly this
(in form of RFC patches, see
http://thread.gmane.org/gmane.comp.version-control.git/281670)

I plan on reviving this soon. Did you solve this problem as Jens proposed
or are you still looking for a solution?

Thanks,
Stefan
