in thread Capturing STDOUT and/or STDERR from Proc::Background

Hey Anonymous Monk, thanks for the reply!

Ok, cool I'll check out those links. Didn't think to check the cache, or to even add something to the background script
that could write out to a file instead of just STDOUT... Wasn't sure if I had mentioned that the background process is also
a script I wrote, so adding something to do the redirecting/capturing sounds like a plan...!

Great Idea...! Thanks!


Thanks Again,
Matt

    I meant Capture::Tiny, along the lines of

    ... my $session = get_session_id(); my $cache = get_cache_handle(); $cache->set( $session, [ 0, "" ] ); # no data yet my $background = go_background( $session ); ... if( not $background->alive ) { if( my $data = $cache->get( $session ) ){ return show_results( $data ); } } ... sub get_cache_handle { use Cache::FileCache; return Cache::FileCache->new ... }

    ## stuffintocache.pl #!/usr/bin/perl -- use strict; use warnings; use Getopt::Long(); use Capture::Tiny qw/ capture /; Main( @ARGV ); exit( 0 ); sub Main { my %opt; Getopt::Long::GetOptionsFromArray( \@_, \%opt, 'session=s', ... ) my($stdout, $stderr, $exit) = capture { system( $cmd, @args ); }; my $session = get_session_id(); my $cache = get_cache_handle(); $cache->set( $session, [ 1, $stdout, $stderr, $exit ] ); return; }
      Hey Anonymous Monk, thanks for the reply!

      Cool, thanks for the examples, much appreciated...
      I just checked out the CPAN link you posted for that Module and I like that you can also just
      include arbitrary code inside the capture() Function/Method and get STDERR/STDOUT and a
      return code from whatever you put inside the capture function... Pretty cool, thanks!
