It is relatively obsolete and has been written out of [Exhibit](https://github.com/zepheira/exhibit3/) entirely. You should probably choose jQuery or other similar tools to meet your needs, this primarily exists as a compatibility shim until it can be replaced. + +Usage +----- + +SimileAjax now comes in two flavors. You can continue to call `simile-ajax-api.js` (a built file) which is a self-contained bundle that should be backwards compatible with any prior usage of the library. + +```html + +``` + +Or you can use your own RequireJS configuration to include SimileAjax in your application. The RequireJS-aware bundled file is quite different from the older convention and should take advantage of the RequireJS config system for setting things embedded URL parameters or global script variables used to provide. A sample configuration: + +```javascript +require.config({ + // ... your other configuration material ... + paths: { + "simile-ajax": "ajax/api/simile-ajax-bundle" + }, + config: { + simile-ajax: { + bundle: true, // default + prefix: "ajax/api" + } + } +}); +require(["simile-ajax"], function(SimileAjax) { + if (SimileAjax.loaded) { + console.log("SimileAjax is working."); + } +}); +``` + +Mailing List and Forum +---------------------- + +Join the community by joining the [Google Group SIMILE Widgets](http://groups.google.com/group/simile-widgets/). + +Licensing +--------- + +SimileAjax is open source software and is licensed under the modified BSD license located in the LICENSE.txt file located in the same directory as this README. + +This code contains libraries found in `src/webapp/api/lib/` that are covered by their own licenses. + + * [RequireJS](http://requirejs.org/) is covered by the [modified BSD license](https://github.com/jrburke/requirejs/blob/master/LICENSE). + * [almond](https://github.com/jrburke/almond) is covered by the [modified BSD license](https://github.com/jrburke/almond/blob/master/LICENSE). + +This code contains libraries found in `lib/` and `optimize/` that support development that are covered by their own licenses. + + * [Jetty](http://jetty.codehaus.org/) is covered by the [Apache 2.0 License](http://jetty.codehaus.org/jetty/license.html) + * [r.js](http://requirejs.org/docs/optimization.html) is covered by the [modified BSD license](https://github.com/jrburke/r.js/blob/master/LICENSE). + +Bundling +-------- + +You will need `ant` and `node` in order to build the SimileAjax bundles.

Also known as aliasing, this feature has been deprecated in the Closure Compiler since its + * initial release, where it is unavailable from the CLI. The Closure Compiler allows one to log and + * influence this process. In contrast, this implementation does not introduce + * any variable declarations in global code and derives String values from + * identifier names used as property accessors.

+ *

Consolidating literals may worsen the data compression ratio when an encoding + * transformation is applied. For instance, jQuery 1.7.1 takes 248235 bytes. + * Building it with + * UglifyJS v1.2.5 results in 93647 bytes (37.73% of the original) which are + * then compressed to 33154 bytes (13.36% of the original) using gzip(1). Building it with the same + * version of UglifyJS 1.2.5 patched with the implementation of consolidation + * results in 80784 bytes (a decrease of 12863 bytes, i.e. 13.74%, in comparison + * to the aforementioned 93647 bytes) which are then compressed to 34013 bytes + * (an increase of 859 bytes, i.e. 2.59%, in comparison to the aforementioned + * 33154 bytes).

+ *

Written in the strict variant + * of ECMA-262 5.1 Edition. Encoded in UTF-8. Follows Revision 2.28 of the Google JavaScript Style Guide (except for the + * discouraged use of the {@code function} tag and the {@code namespace} tag). + * 100% typed for the Closure Compiler Version 1741.
