logger question

Brad Tilley

11/23/2006 10:43:00 PM

Is there a way to make logger not write the header line (first line) of a log
file? I'd rather it not write anything but log entries.

# Logfile created on Thu Nov 23 14:44:09 -0500 2006 by logger.rb/1.5.2.9
log_entry
log_entry
log_entry
...

Thanks,
Brad

$ cat b.rb
require 'logger'

class MyLogger < Logger
def add_log_header(*a, &b) 42 end
end

logger = MyLogger.new STDERR

logger.info{ "implementation inheritance is useful at times" }


$ ruby b.rb
