[log4perl-devel] printf-like messages

[Tomáš N. <ne...@gm...>]

Hello,

I would like to request a feauture for printf-like logging via ->log(), -
>debug(), 

I tried to implement it by myself by subclassing Log::Log4perl (override 
get_logger() to delegage get_logger to my Logger class) and 
Log::Log4perl::Logger (override ->generate_coderef() to do sprintf() before 
passing parameters to the original coderef). However I don't like the way I 
had to override get_logger(), so I decided I rather request it as a feature 
here.

Is it interesting? I can live without it (and use sprintf() return value as a 
parameter to log methods), but it would be nice.

Thank for response.
Thomas.

Yeah, sprintf() should take care of all your formatting needs. I've
found that I use printf() very rarely in Perl, because you can
interpolate variables so elegantly in strings. Also, there's a lot of
hidden functionality in the loggers as is (think about loggers that take
fixed arguments like database loggers, or that you can pass a subroutine
to any logger which it will then evaluate), so having printf-like
functions would considerably complicate things. But thanks for the
suggestion!
