CHANGELOG.md

4.0.5 / 2014-03-19

• Rename MethodChain#_() to MethodChain#__() to avoid clobbering Underscore in test suites

4.0.4 / 2013-12-01

• Remove Enumerable class methods from Test.Unit.TestCase
• Log all mock argument matchers that match a method call, so a test will not fail if two mocks match the same call

• Improve stub error messaging and argument matcher representations

4.0.2 / 2013-07-06

• Change AsyncSteps so it wraps all calls to before(), it() and after() so that each block waits for all the steps it queues to complete

4.0.1 / 2013-07-01

3.0.8 / 2012-08-04

• Ship source maps for minified JavaScript files

• Make Console stringify DOM nodes successfully in Chrome

3.0.6 / 2012-02-20

• Allow packages to contain multiple files as a convenience for loading 3rd-party libraries
• Fix script loading on Adobe AIR
• Fix fetching of scripts over HTTPS in jsbuild, and fail if requests return a non-200 status

• Improvements to jsbuild for managing bundles of scripts

3.0.2 / 2011-07-16

• Exit with non-zero exit status from Test.autorun() if there are any test failures
• Log test progress as JSON so we can pick up test results using PhantomJS
• Allow post-test reports to cause the build to fail by returning false from report(). e.g. Coverage can cause a red build if it finds methods that were not called
• Use synchronous console.warn() to produce output in Node, and System.out.print[ln] on Rhino platforms

3.0.1 / 2011-06-17

• Adds NPM package and jsbuild command-line program for bundling required modules for deployment, called jsbuild
• When using JS.require(), scripts from the same domain are prefetched over XHR to maximize parallel downloading
• Fixes support for negative mock expectations, e.g. expect(object, 'm').exactly(0)
• Fixes scheduling bugs in FakeClock so that current time remains correct when removing and restoring timers
• Avoids stubbing of setTimeout() inside AsyncSteps, otherwise it becomes very hard to use with FakeClock

3.0.0 / 2011-02-28

• All components now run on a much wider array of platforms
• JS.Class is now tested using its own test framework, JS.Test
• New libraries: Benchmark, Console, Deferrable, OrderedHash, Range, OrderedSet, TSort
• HashSet has become the base Set implementation, and the original Set implementation has been removed
• StackTrace has been totally overhauled to support extensible user-defined tracing functionality
• New core method Module#alias() for aliasing methods
• User-defined keyword methods using Method.keyword()
• JS.Class no longer supports subclassing the Class class
• Module#instanceMethod() returns a Method, not a Function
• Enumerable#grep() now supports selecting by type, e.g. items.grep(Array). It does not support functional predicates like items.grep(function(x) { return x == 0 }), you should use Enumerable#select() for this
• Objects with the same properties, and Arrays with the same elements are now considered equal when used as Hash keys
• MethodChain#fire() is now called MethodChain#__exec__()
• JS.Ruby has been removed
• JS.State now adds states() as a class method, rather than a macro in the class body. All classes using 'inline' states MUST call this method to declare and resolve their states

2.1.5 / 2010-06-05

• Adds support for Node, Narwhal and Windows Script Host to the JS.Package loading system
• Adds an autoload macro to the package system for quickly configuring modules using filename conventions
• Renames require() to JS.require() so as not to conflict with CommonJS module API

2.1.4 / 2010-03-09

• Rewritten the package loader to use event listeners to trigger loading of dependencies rather than polling for readiness
• package.js and loader.js no longer depend on or include the JS.Class core; you must call require() to use JS.Class, JS.Module, JS.Interface or JS.Singleton
• Fix bug in browser package loader in environments that have a global console object with no info() method

2.1.3 / 2009-10-10

• Fixes the load() function in the Packages DSL, and adds some caching to improve lookup times for finding a package by the name of its provided objects
• Non-existent package errors are now defered until you require() an object rather than being thrown at package definition time. This means require() won't complain about being passed native objects or objects loaded by other means, as long as the required object does actually exist
• MethodChain now adds instance methods from Modules, and adds methods that were defined before MethodChain was loaded
• State now supports callSuper() to state methods imported from mixins; previously you could only callSuper() to the superclass

2.1.2 / 2009-08-11

• LinkedList was defined twice in the stdlib.js bundle; this is now fixed (thanks @skim)

2.1.1 / 2009-07-06

• Fixes a couple of Set bugs: Set#isProperSuperset had a missing argument, and incomparable objects were being allowed into SortedSet collections

2.1.0 / 2009-06-08

• New libraries: ConstantScope, Hash, HashSet
• Improved package manager, supports parallel downloads in web browsers and now also works on server-side platforms (tested on SpiderMonkey, Rhino and V8). Also supports custom loader functions for integration with Google, YUI etc
• Enumerable updated with Ruby 1.9 methods, enumerators, and Symbol#to_proc functionality when passing strings to iterators. Any object with a toFunction() method can be used as an iterator. Search methods now use equals() where possible
• ObjectMethods module is now called Kernel
• New Kernel methods: tap(), equals(), hash(), enumFor() and methods(), and new Module methods: instanceMethods() and match()
• The double inclusion problem is now fixed, i.e. the following works in JS.Class 2.1:

A = new JS.Module();
C = new JS.Class({ include: A });
B = new JS.Module({ foo: function() { return 'B#foo' } });
A.include(B);
D = new JS.Class({ include: A });

new C().foo()   // -> 'B#foo'
new D().foo()   // -> 'B#foo'

• Ancestor and method lookups are cached for improved performance
• Automatic generation of displayName on methods for integration with the WebKit debugger
• API change: Set#classify now returns a Hash, not an Object
• PDoc documentation for the core classes

1.6.3 / 2009-03-04

• Fixes a bug caused by Function#prototype becoming a non-enumerable property in Safari 4, causing classes to inherit from themselves and leading to stack overflows

2.0.2 / 2008-10-01

• The function returned by object.method('callSuper') now behaves correctly when called after the containing method has returned

1.6.2 / 2008-10-01

• Fixes some bugs to make various forEach() methods more robust

2.0.1 / 2008-09-14

• Fixes a super()-related bug in Command
• Better handling of include and extend directives such that these are processed before all the other methods are added. This allows mixins to override parts of the including class to affect future method definitions
• Module#include() has been fixed so that overriding it produces more sane behaviour with respect to classes that delegate to a module behind the scenes to store methods

2.0.0 / 2008-08-12

• Complete rewrite of the core, including a proper implementation of Module with all inheritance semantics based around this. Ruby-style multiple inheritance now works correctly, and callSuper() can call methods from mixins
• Class and Module are now classes, and must be created using the new keyword
• Some backward compatibility breaks
• New method: Object#__eigen__() returns an object's metaclass
• Performance of super() calls is much improved
• New libraries: Package, Set, SortedSet and StackTrace
• Package provides a dependency-aware system for loading new JavaScript files on demand

1.6.1 / 2008-04-17

• Fixes bug in Decorator and Proxy.Virtual caused by the klass property being treated as a method and delegated

1.6.0 / 2008-04-10

• Adds a DSL for defining classes in a more Ruby-like way using procedures rather than declarations (experimental)
• New libraries: Forwardable, State
• The extended() hook is now supported
• The implement directive is no longer supported

1.5.0 / 2008-02-25

• Adds a standard library, including Command, Comparable, Decorator, Enumerable, LinkedList, MethodChain, Observable and Proxy.Virtual
• Renames _super() to callSuper() to avoid problems with PackR's private variable shrinking
• Adds an Object#wait() method that calls a MethodChain on the object using setTimeout()

1.0.1 / 2008-01-14

• Memoizes calls to Object#method() so that the same function object is returned each time

1.0.0 / 2008-01-04

• Singleton methods that call super() are now supported
• Object#is_a() has been renamed to Object#isA()
• Classes now support inherited() and included() hooks
• Adds Interface class for easier duck-typing checks across several methods
• New directive implement can be used to check that a class implements some interfaces
• Singletons are now supported as class-like definitions that yield a single object
• Module has been added as a way to protect sets of methods by wrapping them in a closure
• Removes the bindMethods class flag in favour of the more efficient and Ruby-like Ojbect#method(). This can also be used on classes to get bound class methods
• Exceptions thrown while calling super are no longer swallowed inside the framework
• Class#method() is now Class#instanceMethod

0.9.2 / 2007-11-13

• Fixes bug caused by multiple methods in the same call stack clobbering _super()
• Fixes some inheritance bugs related to class methods and built-in instance methods
• Improves performance by bootstrapping JavaScript's prototypes for instance method inheritance
• Allows inheritance from non-JS.Class-based classes

0.9.1 / 2007-11-12

• Improves performance by checking whether methods use _super() and only wrapping where necessary

0.9.0 / 2007-11-11

• Initial release. Features single inheritance and _super()
