Answer 1

We use Quack to pull a specific module from another Git repository. We need to pull code without the whole code base of the provided repository - we need a very specific module / file from that huge repository and should be updated every time we run update.

So we achieved it in this way:

Create configuration

name: Project Name

modules:
  local/path:
    repository: https://github.com//.git
    path: repo/path
    branch: dev
  other/local/path/filename.txt:
    repository: https://github.com//.git
    hexsha: 9e3e9642cfea36f4ae216d27df100134920143b9
    path: repo/path/filename.txt

profiles:
  init:
    tasks: ['modules']

With the above configuration, it creates one directory from the provided GitHub repository as specified in first module configuration, and the other one is to pull and create a file from the given repository.

Other developers just need to run

$ quack

And it pulls the code from the above configurations.
