Stringify::Deep - Stringifies elements in data structures for easy serialization
my $struct = { foo => 1, bar => [ 1, 2, 7, { blah => $some_obj, # Object that's overloaded so it stringifies to "1234" foo => [ 1, 2, 3, 4, 5 ], } ], }; $struct = deep_stringify($struct); # $struct is now: # { # foo => 1, # bar => [ 1, 2, 7, { # blah => "1234", # foo => [ 1, 2, 3, 4, 5 ], # } ], # }
Let's say that you have a complex data structure that you need to serialize using one of the dozens of tools available on the CPAN, but the structure contains objects, code references, or other things that don't serialize so nicely.
Given a data structure, this module will return the same data structure, but with all contained objects/references that aren't ARRAY or HASH references evaluated as a string.
Given a data structure, returns the same structure, but with all contained objects/references other than ARRAY and HASH references evaluated as a string.
Takes an optional hash reference of parameters:
leave_unoverloaded_objects_intact
If this parameter is passed, Stringify::Deep will unbless and stringify objects that overload stringification, but will leave the data structure intact for objects that don't overload stringification.
