Calling a class method with self. doesn't work?

Ruby
#1

Hey guys

This may be a very beginner’s question, but I just don’t get it. This
works:

module MyModule
class MyClass
def file_colon_line(*arg)
MyModule::MyClass::textmate_colon_line(old_file_colon_line)
end

  def self.textmate_colon_line(file_colon_line)
    # ...
  end
end

end

But I’d rather just use self when calling text_mate_colon_line like
this:

self::textmate_colon_line(old_file_colon_line)

But this doesn’t work (method not found). What’s the right way to do it?

Thanks,
Josh

self always points current scope. so, to call class method from the
instance method, use self.class.method_name:

module MyModule
class MyClass
def file_colon_line(*arg)
self.class.textmate_colon_line(old_file_colon_line)
end

  def self.textmate_colon_line(file_colon_line)
    # ...
  end
end

end
