Description

SNUSP is a two-dimensional programming language described here:

• http://c2.com/cgi/wiki?SnuspLanguage

• http://rosettacode.org/wiki/Category:SNUSP

Here is the well-known FizzBuzz algorithm, written in SNUSP:

/               'B' @=@@=@@++++#
           // /             'u' @@@@@=@+++++#
          // // /           'z' @=@@@@+@++++#
         // // // /         'i' @@@@@@=+++++#
        // // // // /       'F' @@@=@@+++++#
       // // // // // /      LF  ++++++++++#
      // // // // // // /   100 @@@=@@@=++++#
    $@/>@/>@/>@/>@/>@/>@/\   0
    /                    /
    !                             /======= Fizz <<<.<.<..>>>#

This module installs a SNUSP interpreter so that you can run this code yourself. It also installs a visual debugger, to help you follow the flow of SNUSP programs.

Try it. It's very cool!

Credit

This code originated from http://c2.com/cgi/wiki?SnuspLanguage but has been fairly heavily refactored to be clear, DRY and conform to modern Perl standards.

I have packaged it on CPAN and GitHub for easy installation and continued maintenance.
