Re: printing all commands' return value in debugger

I'm often using the debugger as a scratchpad to try things out. I'd
like to see the return value of all commands I type, so I don't have
to start each line with "p"- that is, something like:
perl -de 1
DB<3> print $a
I can't figure out how to twist the debugger commands/options around
to get this "auto-print" going! Any ideas?
I remember seeing someone's post a few years ago that addressed a
similar issue, but for the life of me I can't seem to locate it.
Anyway, you could try the follwoing:
perl -wne 'print eval, "$@\n> "' # for UNIX
perl -wne "print eval, qq/$@\n> /" # for DOS
That way, you can type the following input and get the following
(Note that "51" shows up because you didn't print a newline after
(Also note that, unlike the debugger, you can't exit by typing "q".
Instead, you exit by typing "exit".)
This is pretty much what you wanted, right? To be honest, I don't
really see what's so hard about using the regular perl debugger and
typing "p" or "x" before every statement (I would think that's easier
than typing out the full one-liner I gave above), but if you prefer it
that way, go ahead and use it.
(Like you, I use the debugger as a scratchpad all the time, but I
don't consider typing "x" in front of statements to be a hassle.)
I hope this helps, yary.
