Properly handle error subtype #constructor (#__constructor alias) 
Using `#constructor' in place of `#__construct' caused an error attempting
to "redefine" `#__constructor' (once the alias was applied); the system was
making improper assumptions and not accounting for aliases.

In fact, everthing about how this was being done was bad, since adding any
keywords would have thrown it off as well!

* lib/ClassBuilder.js (build): Move ector detection past prop
  parsing.  Check parsed properties instead of raw.
* test/ClassBuilder/ErrorExtendTest.js: Iterate ctor override test on new
    `ctors'.
  (caseSetUp) [ctors]: Add property.

GNU ease.js

GNU ease.js is a classical object-oriented framework for Javascript, intended to eliminate boilerplate code and "ease" the transition into JavaScript from other object-oriented languages.

Current support includes:

  • Simple and intuitive class definitions
  • Classical inheritance
  • Traits as mixins
  • Access modifiers (public, protected, and private)
  • Abstract classes and methods
  • Interfaces
  • Static and constant members
  • Transparent error subtyping

Documentation

Comprehensive documentation and examples are available on the GNU ease.js website and in its manual.

Bug Reports / Feature Requests

Please direct bug reports and feature requests to bug-easejs@gnu.org or the project page on Savannah.

Why Classical OOP in JavaScript?

GNU ease.js was created (historically) for a number of reasons:

  • To "ease" object-oriented developers into JavaScript by providing a familiar environment.
  • To provide the maintenance and development benefits of classical OOP.
  • To provide features not included in the language, such as proper encapsulation through private/protected members, interfaces, traits, intuitive inheritance, and other conveniences.
  • To encapsulate the hacks commonly used to perform the above tasks.

Many JS purists believe that classical object-oriented programming should be left out of JavaScript and that one should stick strictly to prototypal development. While the two are related (they are both object-oriented), they can be applied to different problem domains in order to achieve results that are more natural or intuitive to developers; GNU ease.js works seamlessly with existing prototypes, allowing the developer to choose whether or not they want to use "classes".

Building and Installation

For information on installing ease.js on your system, see INSTALL. Alternatively, you may install the software using npm by issuing the following command:

$ npm install easejs

Configuring

If your distribution contains a configure file in the project root, you may jump immediately to INSTALL.

Otherwise, you likely have the sources as they exist in the project repository, which does not contain the generated `configure' script; you may generate it by issuing the following command:

$ autoreconf -fvi

Please note that certain files (such as AUTHORS, NEWS, and ChangeLog) are generated as part of the dist target and do not exist as part of the repository.
