DESCRIPTION

This module adds a create_structured_tree subroutine to the Directory::Scratch.

DOCUMENTATION

I needed a subroutine to create a bunch of temporary directories and files while running tests. I used the excellent Directory::Scratch to implement such a functionality. I proposed the subroutine to the Directory::Scratch author but he preferred to implement a subroutine using an unstructured input data based on the fact that Directory::Scratch didn't use structured data. This is, IMHO, flawed design, though it may require slightly less typing.

I proposed a hybrid solution to reduce the amount of subroutines and integrate the subroutine using structured input into Directory::Scratch but we didn't reach an agreement on the API. Instead I decided that I would piggyback on Directory::Scratch.

You can access create_structured_tree through a subroutine or a method through a Directory::Scratch object.

Whichever interface you choose, the argument to the create_structured_tree consists of tuples (hash entries). The key represents the name of the object to create in the directory.

If the value is of type:

ARRAY

A file will be created, it's contents are the contents of the array (See Directory::Scratch)

HASH

A directory will be created. the element of the hash will also be , recursively, created

OTHER

The subroutine will croak.

SUBROUTINES/METHODS

  use Directory::Scratch::Structured qw(create_structured_tree) ;
  
  my $temporary_directory = create_structured_tree(%tree_structure) ;
  my $base = $temporary_directory->base() ;

  use Directory::Scratch ;
  use Directory::Scratch::Structured qw(piggyback_directory_scratch) ;
 
  my $temporary_directory = Directory::Scratch->new;
  $temporary_directory->create_structured_tree(%tree_structure) ;

BUGS AND LIMITATIONS

None so far.
