Re: [log4perl-devel] [unclassified] Re: log and exit in one function call. How ?

[Kristis M. <kri...@as...>]

Hey Mike, thanks again for your help.

Would it make sense to have another interface that allows one to specify
the exit value ? Doing the following e.g.

$Log::Log4perl::LOGEXIT_CODE = 113;
$logger->logdie( "my message" );

Is still two lines of code instead of one. I was hoping for the
possibility that a function like:

$logger->logdie ( "my message", 113 ); 

existed, or could be added in log4perl. I mean, I don't see how what is
suggested for suppressing duplicate logdie messages is any different, or
more efficient, than:

$logger->error( "my message" ) && exit 113;


In particular, I'm trying to "format" messages before I emit them
through the logger. This requires me to always call something like:

$logger->error ( my_special_function_that_formats_the_message
( $error_value, "my message") );

and I'm trying to avoid calling

$logger->error ( my_special_function_that_formats_the_message
( $error_value, "my message") ) && exit $error_value;

This all looks and feel dirty.

I'm essentially constructing parts of the ConversionPattern (perhaps
there's a better way to do this). Would it be a good idea for log4perl
to provide a way for both allowing multiple arguments supplied to the
ConversionPattern, and also supplying an (optional) error code ? It is
natural that error log messages also contain an error value. I'd like to
construct the message in the ConversionPattern to include the error
code, and also exit with that error code.
