Hello,
I need a small bit of help, I am playing with Logger class and ran into a small problem I am not sure how to solve. Namely, I was interested in command line setting of the logging level, however, the passed argument is not accepted as a method name nor can I figure out how to get the arg "coherced" to a string prior to evaluation of the method call. Here is my code:
when "--debug"
if(DEBUG_LEVELS.include?(arg))
mylog.level = Logger::arg.to_s
^^^^^^^^^^^^
else
puts " "Debug level can be one of DEBUG, INFO, WARN, ERROR, or FATAL."
.....
(hi-lited is the code segment in question)
I am using GetoptLong to do the cmd line processing. The error given by ruby is:
test.rb:136 undefined method `arg' for Logger:Class (NoMethodError)
...
TIA,
Phy

Logger#level actually takes an integer. Maybe something like this:
if Logger::Severity.const_defined?(arg)
mylog.level = Logger::Severity.const_get(arg)
else
puts "Debug level must be one of #{Logger.Severity.constants.join(',')."
end
