I do believe log4r has a rolling file appender that will perform date/  
size based rolling of your log files. This will not alter the basename  
of the log file, just increment a counter …

basename.1.log  
basename.2.log  
etc.

Changing the basename is something you would have to do  
programatically from your own code. I do not think log4r supports that.

Hi Col,  
of course you can. Pls use the outputter DateFileOutputter.  
Have a look at the files in gems’ example directory:  
/install\_dir/ruby/lib/ruby/gems/1.8/gems/log4r-1.0.5/examples:  
yaml.rb & log4r\_yaml.yaml.

You can change the logfile name each year or month or day or hour or  
minute …

Cheers

Andreas
