in reply to Neat Debugger tricks

One I use is to use Data::Dumper to display complex data structures whilst in the dbgr

DB<6>use Data::Dumper DB<7>print Dumper($complexity)

I think used in conjunction with the first point (opening a file handle in the dbgr) this could a neat way to capture an object or structure to a file at a point in time

    Or, if your development environment supports dotty (the interactive dot environment from graphviz), you can install Devel::Command::Viz and get pictures of your data structures drawn with dot by GraphViz::Data::Structure.

    Disclaimer: I wrote both of these and for the two or three times I've really needed them, they really helped.

    Sometime I should tell the story of how wanting to do this got me into completely recommenting the debugger...
