Enumeration of variables in current and higher frames

I am trying to debug a script with perl -d ... After I break down where I want, I would like to print the current environment and the environment from higher frames.

I see the stack through T Now, if I try V , I get a list of everything that is pretty much useless, since it includes things like SO_BROADCAST constants, etc. How can I filter them and get only local ones?

How do I do the same for higher frames?

Also, how do I print code around a line of a higher stack frame? V / l performs only the current one.

Have you tried y [level] , which shows lexical (my) variables in the current or higher (specified level )?

Provided that you mean "getting only local", of course.

You can also use the PadWalker module to provide you with a list of lexical files in a given area. The peek_my and peek_our return a hashref of variables in scope in the relative frame of the call (0 - current frame, 1 - calling frame, ...)
