Question about Lo4R


#1

Hello,
I’m having an issue with a Formatter for Log4R.

I’m trying to use the %c format directive to display the Line Number of
the file and for some reason it keeps throwing an error.

I’m using Ubuntu Breezy 5.1, Ruby 1.8.3, and Log4R 1.0.5. Is anyone else
having any similar issues?

Error Msg :
(eval):2:in format': undefined method[]’ for nil:NilClass
(NoMethodError)
from
/usr/local/lib/site_ruby/1.8/log4r/outputter/outputter.rb:118:in

from ./blah.rb:37:in `happy’

Here is the small snipbit of code

require ‘log4r’
include Log4r

class MyClass

    def initialize
            puts('init')
            @my_log = Logger.new 'myLog'
            formatter =
                    PatternFormatter.new(

#:pattern => “%l[%d] %t %1M”)
:pattern => “%5l [%d] %t: %.25M”,
:date_pattern => “%H:%M:%S”)
@my_log.outputters = FileOutputter.new(‘myLog’,
:filename => “log_file”,
:trunc => false,
:formatter => formatter)

            puts(Kernel.caller[0].to_s)
    end

    protected
    def logger
            puts("got logger")
            @my_log
    end

end

class MyChild < MyClass
def initialize
super
end

    def happy
            logger.debug('happy')
    end

end

c = MyChild.new
c.happy

I’d appreciate any and all input. Thanks!

Just a note, the ruby included with breezy is not 1.8.3 release. ruby -v
Most people build their own snapshot of ruby. I never trust a
distributors
ruby because they 1) keep taking snapshots from a SCM, or 2) make
modifications which break existing code.

Exactly, 1.8.3 was released on 09/21/2005. Somebody took a development
snapshot instead of taking critical patches and declared it the ruby to
be
used in Ubuntu Breezy. The people who noticed the version were a bit too
late
and Breezy had already been frozen.
