NAME
Devel::Command::Viz - graph data structures under the debugger
SYNOPSIS
# in .perldb:
use Devel::Command;
sub afterinit {
Devel::Command->install;
}
# In the debugger:
DB<1> my $a = [1, 2, {3=>4}, [5.6]]
DB<2> viz $a
# A 'dotty' window pops up, showing the data structure.
DESCRIPTION
Devel::Command::Viz
is a debugger extension command plugin for Devel::Command. It uses GraphViz::Data::Structure
to visualize a Perl data structure and dotty
to display the resultant graph.
ROUTINES
command
Standard Devel::Command
wrapper code to parse a debugger command line, render the graph, and display it.
BUGS
None known; it's possible that the resultant graphs may have probelms due to as-yet-uncaught bugs in GraphViz::Data::Structure
.
The command will not work if you have no way of running dotty
, which requires X Windows to be running.
