how can I get the following to work, what am I not understanding about how
modules work?
there are many ways, but i usually start as simple as possible,
creating modules by fxn. classes simple as possible
# we have module that defines method
module MakeMethod
def make_method( name )
define_method( name ) do |count|
puts "you called method #{name.to_s}"
puts "the count is #{count}"
end
end
end
# we have module that modifies a class and creates corr methods
module MethodMaker
class<< self
include MakeMethod
end
make_method :hello
make_method :bye
end
# we create class, as simple as possible
class Person
def initialize( name )
@name = name
end
def greet
puts "Hello! I'm #...@name}"
end
end
# we create person class. it works
j=Person.new "rajin"
# but hello method does not work yet since we've not defined it yet on
person class
# j.hello 1 => will err here
# now we modify person
class Person
include MethodMaker
end
# the new methods now work
j.hello 1
j.bye 1
best regards

what i would like to do is be able to use make_method from class Person,
like:
class Person
include MethodMaker
make_method :hello
make_method :bye
end
