Getting the current module(s), class name and method in Ruby 1.9

[Iñaki Baz Castillo]

Hi, first of all I'm sorry since I already did this question some time ago=
=20
(but I ca't find it now).

Basically I want the following:

=2D--------------
module MyModule

class MyClass
def show_log
puts "I'm here: ###### FIXME ######"
end
end

end


my_class =3D MyModule::MyClass.new
my_class.show_log
=3D> I'm here: MyModule::MyClass#show_log
=2D--------------

When I did this question I remember that it was not possible with Ruby 1.8 =
but=20
it was feasible in Ruby 1.9.

Could you please show me how to get it?
Thanks a lot.

Something I prefer to use is the __LINE__ and __FILE__ constants. They
work a treat!

That's ok, but it's not what I'm looking for.
Basically I want a logger that shows the current module(s), class name and=
=20
method name.

Thanks.

Hi,

The following works in both 1.8.6 and 1.9.1 (calling_method is by
Robert Klemme - see ruby-talk 205150 & 205950).

module Kernel
private
def calling_method(level =3D 1)
caller[level] =3D~ /`([^']*)'/ and $1
end

def this_method
calling_method
end
end

module MyModule
class MyClass
def show_log
puts "#{self.class}.#{this_method}"
end
end
end

MyModule::MyClass.new.show_log # =3D> MyModule::MyClass.show_log

Regards,
Sean

Fantastic! Thanks a lot.

If somebody is interested, I've implemented the above code adding Class=20
methods logging feature:

=2D---------------
module Kernel
=09
def this_method
if self.class =3D=3D Class
"#{self.to_s}.#{caller[0][/`(.*)'/, 1]}"
else
"#{self.class}##{caller[0][/`(.*)'/, 1]}"
end
end
private :this_method
=09
end



module MM
class AA
def self.class_method
puts this_method
end

def instance_method
puts this_method
end
end
end


MM::AA.class_method
=3D> "MM::AA.class_method"

MM::AA.new.instance_method
=3D> "MM::AA#instance_method"
=2D---------------


Regards.

Hi again. Wouldn't make sense to have such features in Ruby core instead of=
=20
having to parse "caller[0][/`(.*)'/, 1]" and so?

Is it possible to open a feature request for it? or is it too late for such=
=20
wishes in 1.9?

Thanks.
