Title Body

I am using pdl2 (the PDL shell) also as a my default Perl interactive shell (it loads all the nice plugins for Devel::REPL ). But I am missing the x dumper-printing alias. p is nice for piddles but it does not work for a normal array ref or hash ref. I have loaded Data::Dumper but it lacks an easy way of controlling depth and I like the way you can quickly set depth limits with x , e.g. x 2 $deep_datastruct for complex data structures. But with Data::Dumper the process is more cumbersome: pdl> say $c HASH(0x53b0b60) pdl> p $c HASH(0x12b14018) pdl> use Data::Dumper pdl> p Dumper $c $VAR1 = { 'c' => { 'c' => 3, 'a' => 1, 'b' => { 'c' => '3', 'a' => '1', 'b' => '2' } }, 'a' => 1, 'b' => 4 }; pdl> $Data::Dumper::Maxdepth = 1; pdl> p Dumper $c $VAR1 = { 'c' => 'HASH(0x97fba70)', 'a' => 1, 'b' => 4 }; In the Perl debugger you can achieve the same thing with x 1 $c directly. Does pdl2 have something similar and so concise? [update] And related with this question: does pdl2 or Devel::REPL have convenience functions like the Perl debugger commands m or y ? Or should one create a module with PadWalker </a
