Re^2: How to perldebug a Term::ReadLine application (the other way round)

[RonW]

Why not:

DEBUG_TTY=`tty` xterm -e perl -d ./myRLprog.pl

Then in myRLprog.pl, include:

if (defined $ENV{DEBUG_TTY}) {
  my $tty = $ENV{DEBUG_TTY};
  open my $out,'>',$tty;
  open my $in,'<',$tty;
  my $term = Term::ReadLine->new('Simple Perl calc',$in,$out);
} else { ...; }

Would that work?

well this works

PERLDB_OPTS="ReadLine=0" MASTER_TTY=`tty` xterm -e perl -d calc_TRL.pl

otherwise the debugger starts spontaneously to write to the master terminal, IMHO a bug somewhere between debugger and TRL.

My former approach to redirect the app's tty to a slave terminal has the advantage to run without lost of features in IDEs like emacs.

The slave terminal can also be an extra sub-window within the IDE running a terminal emulation.
