Hi, for logging purposes I’d like to print the Modules, Class and Method  
in  
with the logger is called. Imagine this case:

module App  
module TransportLayer  
class Server  
def get\_data()  
…  
…  
logger.info “We are in XXXXXXX”  
end  
end  
end  
end

I’d like to see:  
“We are in App::TransportLayer::Server#get\_data”

Is it possible in anyway? The only I know how to do if getting the  
current  
Class name by doing “self.class.to\_s”.

Thanks a lot.

Ok sorry, I can get the modules and classes via “self.class.to\_s”:  
=\> “App::Transport::Server::TCP”

The only I miss if the method name, is ti possible?

Thanks.

In 1.9 there is Method#name, but in 1.8.6 I think your best bet is to  
parse the output from Kernel#caller.

Look at Facets: facets/ruby.rb. There is 1.8 implementation of  
# **method**.

```
# Retreive the current running method name.
#
# def tester; __method__ ; end
# tester #=> :tester
#
# Technically __callee__ should provided alias names,
# where __method__ should not. But we'll have to
# leave that distinction to Ruby 1.9+.

def __method__
  /\`([^\']+)\'/.match(caller(1).first)[1].to_sym
end

```

Yes, from caller().
