basic question about logging from TT

Maybe a naive question here, but is there some typical
strategy
for logging from TT?

I know I can do:

 [% PERL %]
   print STDERR "message";
 [% END %]

But tedious (and presumably inefficient?)

I'm passing the Apache request object as a param, so I can
do:

 [% r.log_notice("message") %]

which is reasonsable.

But I wonder if I'm missing something else (perhaps
obvious?)


Thanks,

Mark

What about the std(out|err) filters?

I usually do something like this in a PRE_PROCESS config
file:

    [% IF debug;
         MACRO debug_msg(text)
           FILTER stderr; "  # $text\n"; END;
       ELSE;
         debug_msg = '';
       END;
    %]

I use a 'debug' flag (set in my ttree config file or in
variables passed 
in from my Perl code/Apache handle) to enable/disable
debugging en 
masse.  If debugging is on then the debug_msg() MACRO is
defined to 
print its argument to stderr (via the stderr FILTER),
otherwise it's a 
nullup.

Then in my templates I write:

    [% debug_msg("Hello World") %]
