Is possible to support '--depth=1' for plugin install

Is possible to support '--depth=1' for plugin install to enhance the installation speed?

like this:

git clone http:/xxx.git --depth=1

This would not be a hard thing to add in, but I wonder what you have in mind. Is there a particular plugin that takes forever, and you are installing it very frequently?

As known as, It is very slowly to access github.com in the China. So it can speed up the installing progress with depth option

That makes sense. I think I'll be able to write down something to do this weekend.

I explored the idea of adding this functionality to the vundle, but I found that it made the process of updating the plugins overly complicated (especially if they have submodules). I considered the idea of adding a note to the documentation that the best way to update a shallow-cloned git plugin would be to remove and then reinstall the plugin, but I also found this to be too inelegant. There might be a way, though.

For you, though, I'll note the one (ad-hoc) change needed for an initial shallow cloning. Change line 418 of installer.vim from

    let cmd = 'git clone --recursive '.vundle#installer#shellesc(a:bundle.uri).' '.vundle#installer#shellesc(a:bundle.path())

to

    let cmd = 'git clone --recursive --depth=1 --shallow-submodules '.vundle#installer#shellesc(a:bundle.uri).' '.vundle#installer#shellesc(a:bundle.path())

Two directives were added: a depth directive and a shallow-submodules directive. This should work for the vast majority of plugins out there. But note that if you plan on updating a plugin, you should first remove the plugin completely and then install it again.

Hi,

I just googled for this and found #28 which appears to have been merged. But then it must have been reverted at some stage later because I can't find in master.
