Dear Ledgersmb developers in order for me to debug applications I use a
what I call a 'stack trace'. To do this in Ledgersmb I have some code in
the beginning of every subroutine like so:

if ( ${LedgerSMB::Sysconfig::debug} ) {
open FILE, '>>', "../debug.txt";
my $debug_sub = ( caller(0) )[3],;
my $debug_file = __FILE__,;
$debug_sub =~ s/.*:://g;
print FILE __FILE__, " sub $debug_sub Line: ", __LINE__, "\n";
print FILE "Caller: ", caller, "\n\n";
close FILE;
}

Options, options, options....

If you need to do this, you can write Carp::longmess() instead.

However, better IMO is to use Carp::Always and warn(). That way when Carp::Always is loaded you get a full stack trace, and when it is not, you don't.

Another option you can do is alter your log4perl configuration to log to a custom file, and add a %T to the layout pattern. This would require very light patching to Sysconfig.pm (

log4perl.appender.Debug.layout.ConversionPattern = %d - %p - %l -- %m%n

could get changed to

log4perl.appender.Debug.layout.ConversionPattern = %d - %p - %l -- %m%n %T %n

)

Maybe we should make the default configuration read from a log4perl configuration file to make it easier to change?

In Form.pm, User.pm or other frequently hit files I will add varying
levels if ( ${LedgerSMB::Sysconfig::debug} > 2 )

I end up with a file that steps through the program like so:
arap.pl 1310 continue
mainmenu.pl191

pe.pl 1138 sub project_report
mainbin/arap.pl1314
LedgerSMB/PE.pm sub projects Line: 45
Caller: mainbin/pe.pl1146

Is there any easier way to achieve this in 1.4?
Cheers
