NAME

Language::Befunge::Wrapping::LaheySpace - a LaheySpace wrapping

DESCRIPTION

LBW::LaheySpace implements a wrapping as defined in befunge specs - ie, when hitting a bound of the storage, the ip reverses and backtraces until it bumps into another bound, and then it reverses one last time to keep its velocity.

CONSTRUCTOR

LBW::LaheySpace->new;

Creates a new LaheySpace wrapping.

PUBLIC METHODS

$wrapping->wrap( $storage, $ip )

Wrap $ip in $storage according to this module wrapping algorithm. See DESCRIPTION for an overview of the algorithm used.

Note that $ip is already out of bounds, ie, it has been moved once by LBI.

As a side effect, $ip will have its position changed.
