Re: Re: [perl #22758] debugger command "|x" swallows all output
This is a known bug which seems to hit the debugger periodically, and I think is related to the particular combination of modules installed on a given system, in particular Term::ReadLine::Gnu. There is a simple workaround which involves setting, (if I remember correctly), PERLDB_RL=1.You might also try installing Term::ReadLine::Perl, I think that solves it too. Basically, I think PERL_RL just has to be non-zero. Something like this: $> PERL_RL=1 perl -d ... I realize the answer is a bit vague, but my reference is elsewhere, among other things ;-) -- Ciao Richard Foley Ciao - shorter than aufwiedersehen http://www.oreilly.com/catalog/perldebugpr/ -Original Message- > Date: Mon, 1 Aug 2005 11:32:41 +0200 > Subject: Re: [perl #22758] debugger command "|x" swallows all output > From: "Ulrich Windl" <[EMAIL PROTECTED]> > To: "Michael G Schwern via RT" <[EMAIL PROTECTED]> > On 12 Jul 2005 at 16:19, Michael G Schwern via RT wrote: > > > > [EMAIL PROTECTED] - Sun Jun 22 23:53:28 2003]: > > > - > > > The debugger command "x" works as expected, but "|x" shows no > > > output at all: > > > > > > > I am unable to reproduce this problem.

Shouldn't perl print some diagnostics if the pager cannot be found?

What pager does the debugger think you're using? You can find out with this: $ perl -de 1 Loading DB routines from perl5db.pl version 1.28 Editor support available. Enter h or `h h' for help, or `man perldebug' for more help. main::(-e:1): 1 DB<1> print DB::pager |/usr/bin/less
