struct::compare

Compare(3pm)						User Contributed Perl Documentation					      Compare(3pm)

NAME

       Struct::Compare - Recursive diff for perl structures.

SYNOPSIS

	   use Struct::Compare;
	   my $is_different = compare($ref1, $ref2);

DESCRIPTION

       Compares two values of any type and structure and returns true if they are the same. It does a deep comparison of the structures, so a hash
       of a hash of a whatever will be compared correctly.

       This is especially useful for writing unit tests for your modules!

PUBLIC FUNCTIONS

       o   $bool = compare($var1, $var2)

	   Recursively compares $var1 to $var2, returning false if either structure is different than the other at any point. If both are
	   undefined, it returns true as well, because that is considered equal.

BUGS
/NEEDED ENHANCEMENTS
       o   blessed references

	   compare currently does not deal with blessed references. I need to look into how to deal with this.
