.chezmoiexternal - support for git repositories?

[j-xella]

Hi,

Currently, .chezmoiexternal supports files and archives. Is it possible for it to also support git repositories? So that:

archive add ~ git clone
archive update ~ git update --rebase

Here is a use case - many vim plugins these days can simply be installed via git clone into ~/.vim/pack/author/start/xxx folder. It would be great if chezmoi could be configured to do this as a part of set-up. After reading the documentation, I could only come with the following solutions:

• use archives provided by github - but then I would not have access to plugin history
• create some run_xxx.sh script(-s) that would do it - but that would not be very declarative, and potentially require different code for different platforms, etc...

Let's discuss this in issue #1838.
