Class Method Details

.flatten_dep_tree(dep_tree) ⇒ Object

This is experimental code to test the working of the dependency loader - perform a proper dependency related search in the future.

Flatten tree because that is all we know how to deal with for right now. Last dep seen for a given name wins right now.

Return a dependency set given a lockfile.

Parameters:

  • lockfile (Inspec::Lockfile) —

    A lockfile to generate the dependency set from

  • cwd (String) —

    Current working directory for relative path includes

  • vendor_path (String) —

    Path to the vendor directory
