Define a class method

ruby-talk
1

dear list,

I know, I can use send( :define_method, "testmeth") to
define an object method (i.e. a singleton method of a class).

but how can I define a "normal" method within the class (that is available
for the objects)

I simply want to define method to which I pass the name and the code for a
new method to created with a certain class

any ideas?

regards benny

class Foo;end

=> nil

Foo.define_method( :bar ) { "bar" }

NoMethodError: private method `define_method' called for Foo:Class
        from (irb):2

Foo.instance_eval { define_method( :bar ) { "bar" } }

=> #<Proc:0x10180da0@(irb):3>

Foo.new.bar

=> "bar"

Cheers
