= About

Fluently is a JavaScript toolkit for creating FluentInterfaces[http://martinfowler.com/bliki/FluentInterface.html].

I use this to define the mocks, stubs, and expectations in LzTestKit[http://osteele.com/sources/openlaszlo/lztestkit].

= Status

Alpha.  I use this in other projects, but it's got a known bug (chained modifiers
ignore all but the last one), and the API isn't final.

= Examples

With Fluently, you can do this:
    var o = Fluently.make(function(define) {
      define('fn1', function() {console.info('called fn1')});
      define('fn2', function() {console.info('called fn2')});
      define('fn3', function() {return 3});
    });
to define an object with chained methods, that can be invoked thus:
  o.fn1().fn2() // calls fn1 and then fn2
  o.fn2().fn1() // calls fn2 and then fn1
  o.fn1().fn3() // returns 3 (an explicit 'return' breaks the chain)

You can also define modifiers, and aliases:
    var o = Fluently.make(function(define) {
      define('fn1', function() {console.info('called fn1')});
      define('fn2', function() {console.info('called fn2')});
      define.empty('and');
      define.alias('fn3', 'fn1');
      define.modifier('not');
    });
  
  o.fn3(); // same as o.fn1()
  o.fn1().and.fn2() // same as o.fn1().fn2()
  o.fn1().and.not.fn2() // options.not is set when fn2 is called

I've extracted a couple of files, from LzTestKit, into the examples[http://osteele.com/sources/javascript/fluently/examples/]
directory.  These don't run on their own, but at least they show the
code in use.

You can also see a range of examples by viewing the specs[http://osteele.com/sources/javascript/fluently/specs/fluently-specs.js].
