#704 STDERR is not showing in console during debugging

[Håkon Hægland]

Hi. I installed Eclipse 2019-03 on Ubuntu 19.04, then installed EPIC 0.7.7 from epic-ide.org/updates/testing . I am using perl 5.28.1. Here is a small test program, p.pl:

use feature qw(say);
use strict;
use warnings;
say "Hello world";
warn "A warning";
say "Done";

If I run the Eclipse debugger on this, the text "Hello world" and then "Done" is shown in the console as I step through the program. Expected output: As above and also "A warning" should be shown in red.

If I right-click the console and click "Preferences", the item "Show when program writes to standard error " is checked, and the "standard error text color" is set to red color, see attached screen shot.
So I cannot see that I missed some obvious settings.

I also tried to force STDERR to STDOUT, by adding

open(STDERR, ">&STDOUT");

or by adding

STDERR = STDOUT;

to the top of the script, but it did not help.

I have looked at the source code at https://github.com/jploski/epic-ide but I am not familar with java and I could not find any information about how to compile and deploy changes to the source.

This problem also affects another user, see

Thanks for working on this great plugin!

Hi,

I have not experienced your issue, with various versions of Perl and EPIC, all on Windows 10.
I have not tried to run your program, but here are a few items you could try. The first line sets a variable you can use to conditionally execute code while running under EPIC.

my $running_with_debugger = 1 if ($ENV{PERLDB_PIDS} eq $$); # $$ is the process ID of the current perl script

  STDOUT->autoflush(1); # To make sure messages are not printed out of order
  STDERR->autoflush(1); # To make sure messages are not printed out of order

I hope this helps.
