[log4perl-devel] log4perl Data::Dumper and renaming $VAR1

2010-04-08 Thread Josh803316 
I often use Data::Dumper like this:

print Data::Dumepr->Dump([$name],['name']);

# Which will dump with the variable $name = {   } instead of $VAR1 = {
... }

I use log4perl and Data::Dumper like this (from the log4perl faq)

$logger->trace( {filter => \&Data::Dumper::Dumper, value => $name}, undef,
$TRACE, undef, undef);


So my question is, how can I log the value so it looks like $name instead of
$VAR1 in the saved log?

You can pass a reference to a subroutine to Log4perl's logging methods:

  $logger->trace( sub { Data::Dumper->Dump([$name], ['name']) } );

would do the trick while retaining the time-saving late evaluation.
