NAME

Data::InputMonster::Util - handy routines for use with the input monster

VERSION

version 0.010

DESCRIPTION

These methods, which provide some helpers for use with InputMonster, can be exported as routines upon request.

METHODS

dig

  my $source = dig( [ $key1, $key2, $key2 ]);
  my $source = dig( sub { ... } );

A dig source looks through the input using the given locator. If it's a coderef, the code is called and passed the input. If it's an arrayref, each entry is used, in turn, to subscript the input as a deep data structure. If it's a plain scalar, it's treated like a one-element arrayref would have been.

For example, given:

  $input  = [ { ... }, { ... }, { foo => [ { bar => 13, baz => undef } ] } ];
  $source = dig( [ qw( 2 foo 0 bar ) ] );

The source would find 13.
