Well obviously Ruby and Sass, but what are some other ones?

I'm trying to achieve following:
class A {
def foo() { "foo" }
}
class B {
def bar() { "bar" }
}
A.mixin B
def a = new A()
a.foo() + a.bar()
with one significant difference - I would like to do the mixin on the instance:
a.mixin B
but this results in
groovy.lang.MissingMethodException:…

I am trying to use a mix that calculates the base line height in another that contains my base font styles. Each time I try to compile, I get an error.
Here is an example.
.lineHeight(@sizeValue){
@remValue: @sizeValue;
@pxValue: (@sizeValue * 10);
line-height: ~"@{pxValue}px";
line-height: ~"@{remValue}rem";
}

In Ruby, there's Modules and you can extend a class by "mixing-in" the module.
Module myModule
def printone
print "one"
end
end
Class myClass
extend myModule
end
theOne = myClass.new
theOne.printone
>> one
In Objective-C, I find that I have a set of common methods that I want…

Curious how one would go about calling a class method from inside an instance method of a module which is included by an active record class. For example I want both user and client models to share the nuts and bolts of password encryption.
# app/models
class User < ActiveRecord::Base
include…

In irb, I do this
class Text
include FileUtils
end
I get: NameError: uninitialized constant Test::FileUtils
If I just do: include FileUtils (i.e. now class) everthing works.
What gives?

Here's the scenario: I'd like to have a host class that can have a variable number of mixins (not too hard with variadic templates--see for example http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.103.144). However, I'd also like the mixins to be parameterized by the host class, so that they…

Hi,
Is there a way to redefine SASS mixins. I want to override SASS mixins for site specific styling needs. Is there a way to do it ?

I am wondering when to use mixins? I have read about them. Many authors compare them to interfaces, abstract classes, etc.
Mixins are modules that are mixed-in and modules are a way to group similar methods, constants and classes together.
I have seen examples where a module for math functions…

I need to find an elegant way to do 2 kinds of MixIns.
First:
class A(object):
def method1(self):
do_something()
Now, a MixInClass should make method1 do this: do_other() - A.method1() - do_smth_else() - i.e. basically "wrap" the older function. I'm pretty sure there must exist a good…
