RepoTools

The RepoTools gem can be used to clone Git repositories into a local application and only reclone the Git repository when it is behind origin/master.

The following code will clone the frontend-generators in the /root/path/tmp/test/frontend-generators directory:

puller = RepoTools::Puller.new("git@github.com:MrPowers/frontend-generators.git", "/root/path", "test")
puller.clean_and_clone

If origin/master stays the same and you run #clean_and_clone again, the repo will not be cloned again (because cloning is an expensive operation).

If origin/master is updated, then the repo will be re-cloned. This code will cause the repo to be re-cloned for example:

cd /root/path/tmp/test/frontend-generators
git reset --hard HEAD~4

puller = RepoTools::Puller.new("git@github.com:MrPowers/frontend-generators.git", "/root/path", "test")
puller.clean_and_clone

Add this line to your application's Gemfile:

gem 'repo_tools'

And then execute:

$ bundle
