From not.com@gmail.com

I have been trying to discover why the plain-vanilla perl debegger
isn't sourcing ./.perldb and found two issues while looking
through the perl5db.pl source code​:

1. lines 1372+ of perl5db.pl say​:
if ( -e "/dev/tty" ) { # this is the wrong metric!
  $rcfile = ".perldb";
}
else {
  $rcfile = "perldb.ini";
}

- since the comment shows that the writer knew it was a poor way
of testing for interactivity, I'm not reporting it, but I did need
to quote those lines for the "real" issue I want to report​:

The perl debugger will look in the current directory for either
.perldb or perdb.ini BUT the perldb perldoc only mentions .perldb
and omits any mention of perldb.ini

This is the case even in perl 5.16.2 "perldebug" man page- so even
though this report is being written from 5.10.0, this doc omission
persisists to recent perls.

I suspect the issue that will emerge here is​: What information should
be in the POD for lib/perl5db.pl and what should be in pod/perldebug.pod?

Since I've never meddled with .perldb or perldb.ini, I don't have an
answer to that.

However, if you want to move the discussion forward, may I suggest that
you provide a patch to pod/perldebug.pod that you think would improve
the situation?

If you can supply a patch, please provide it as an email attachment or
an attachment to RT #117809, rather than in the body of an email or posting.

Thank you very much.

Thank you. :)

I can commit this to blead or you could create a Pull Request (or provide a full patch file with credit) and have your name added to AUTHORS.

Which would you like?

Go ahead and commit it in your account- when I have something substantial enough to fork & PR will be happy to, this doc adjustment is tiny!
