Hmm, personally I would prefer loading those pluggable files explicitly
- even if via a special method that only passes a directory name.
Library code typically resides in a different location than user
extensions so for me this makes more sense. In that case I would do
class Foo
def self.load_plugins(dir_or_file)
...
end
end
and then
require 'foo'
Foo.load_plugins ENV["HOME"] + "/foo_extension"
You could even make it more implicit by defaulting to an environment
variable.
class Foo
def self.load_plugins(dir_or_file = ENV['FOO_PLUGINS'])
...
end
end

Indeed, that's a downside. OTOH, I'd rather opt for fixing that then
neglecting autoload. It is apparent: I don't do gem development and I
rarely use gems. :-)

Hmm, I see your point. I am wondering though whether that might not be
too much magic.

Ah, I see! It seems for the class level methods one needs a second
module which is automatically used to extend a class that includes the
visible module. I agree, that's a bit clumsy.
module X
module Xcl
def bar
puts "X::bar"
end
end
def self.included cl
cl.extend Xcl
end
def foo
puts "foo"
self.class.bar
end
end
class A
include X
def self.bar
puts "A::bar"
super
end
end
irb(main):042:0* A.new.foo
foo
A::bar
X::bar
=> nil
But not really hard.

Ok, I'll try to.
