NAME

  pdl2 - Simple shell (version 2) for PDL

SYNOPSIS

  Use PDL interactively:

  %> pdl2

  pdl> $a = sequence(10)  # or any other perl or PDL command
  
  pdl> print "\$a = $a\n"; 
  $a = [0 1 2 3 4 5 6 7 8 9]

DESCRIPTION

The pdl2 program, also known as the Perldl2 shell, is a second generation version of the original perldl interactive PDL shell. It attempts to be backward compatible in usage while providing improved more features, better support for Perl syntax, built on an easier to extend framework based on Devel::REPL.

If you have Devel::REPL version 1.003011 or later, then pdl2 will start with full functionality. If Devel::REPL is not installed or found then pdl2 will print a warning and run the legacy perldl shell command instead.

By default, command lines beginning with the default prompt of either pdl2 or perldl (one of 'pdl> ', 'PDL> ', or 'perldl> ') will have the prefix string and surrounding whitespace stripped. This allows for easy cut-and-paste from example PDL shell sessions or examples into another shell session.
