Copyright for the GNU ease.js project has been assigned to the Free Software Foundation. This allows the FSF to enforce the project licenses, which is something that I lack the time and money to do. It further ensures, through the contract I signed with the FSF, that all distrbutions of GNU ease.js, and all derivatives, will always ``be on terms that explicitly and perpetually permit anyone possessing a copy of the work to which the terms apply, and possessing accurate notice of these terms, to redistribute copies of the work to anyone on the same terms'' and that the project ``shall be offered in the form of machine-readable source code''. Consequently, any contributors to the project (aside from changes deemed to be trivial) will be required to assign copyright to the FSF; this puts GNU ease.js on a firm legal ground to prevent complicating enforcement. Contributors can rest assured that the code they contribute will always remain free (as in freedom). I thank Donald Robertson III of the FSF for his help and guidance during this process. |

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
- Abstract classes and methods
- Interfaces
- Traits as mixins
- Visibility (public, protected, and private members)
- Static and constant members
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".
