Method: Gash::Helpers#normalize

Defined in:
lib/gash.rb

#normalize(value) ⇒ Object

Converts the value to a Tree or a Blob, using some rules:

If value is already a Tree or a Blob:

  • If value comes from another repo, we load it and return a deep copy.

  • If value got no parent, we simply return the same tree.

  • If value‘s parent is self, we also return the same tree.

  • If value‘s parent is something else, we return a duplicated tree.

If it’s something else:

  • If value is a Hash, we create a Tree from it.

  • If it’s not any of the former rules, we turn it into a string and create a Blob from it.
