> yes, it's still unclear for me if you want to step thru or run an automatic trace.

I think stepping thru the code would imply an interactive session. I am looking for an automatic trace, it would be nice to indicate which lines/variables should be printed, but having something that prints all of the variables modified and statements run would suffice. (huge output, but that isn't a problem!) There are some autotrace modules that may work, but I would like to accomplish this without additional modules. (lets make believe we are air gapped and getting to cpan is a problem)

> At least in .perldb with afterinit
sub afterinit { push @DB::typeahead, "b 4", "b 6"; }

So this isn't exactly thru the $ENV{PERLDB_OPTS} environment variable but using a file .perldb is easy enough to do. (though, @DB::typeahead is not a supported interface and is subject to change in future releases.)

I attempted the following:
echo "sub afterinit { push @DB::typeahead, \"a 119 p \$var\"; }" > .perldb

I see:


 29: main();
auto(-1) DB<1> a 199 p __DB<2> (some program output)
and then it shows 6556 segmentation fault  with exit code 139.

not sure what is causing the seg fault and I again lose the automatic printing of all the statements, but I see some of the program output. Hopefully the above typeahead gives you an idea of what I'm trying to accomplish.


Thanks again for all the thought and replies.
