  190. I handle sending messages to JavaScript objects, making JavaScript object accessing from Amber fully transparent.
  191. My instances make intensive use of `#doesNotUnderstand:`.
  192. My instances are automatically created by Amber whenever a message is sent to a JavaScript object.
  193. ## Usage examples
  194. JSObjectProxy objects are instanciated by Amber when a Smalltalk message is sent to a JavaScript object.
  195. window alert: 'hello world'.
  196. window inspect.
  197. (window jQuery: 'body') append: 'hello world'
  198. Amber messages sends are converted to JavaScript function calls or object property access _(in this order)_. If n one of them match, a `MessageNotUnderstood` error will be thrown.
  199. ## Message conversion rules
  200. - `someUser name` becomes `someUser.name`
  201. - `someUser name: 'John'` becomes `someUser name = "John"`
  202. - `console log: 'hello world'` becomes `console.log('hello world')`
  203. - `(window jQuery: 'foo') css: 'background' color: 'red'` becomes `window.jQuery('foo').css('background', 'red')`
  204. __Note:__ For keyword-based messages, only the first keyword is kept: `window foo: 1 bar: 2` is equivalent to `window foo: 1 baz: 2`.!

  349. I am similar to a "class category" typically found in other Smalltalks like Pharo or Squeak. Amber does not have class categories anymore, it had in the beginning but now each class in the system knows which package it belongs to.
  350. Each package has a name and can be queried for its classes, but it will then resort to a reverse scan of all classes to find them.
  351. ## API
  352. Packages are manipulated through "Smalltalk current", like for example finding one based on a name or with `Package class >> #name` directly:
  353. Smalltalk current packageAt: 'Kernel'
  354. Package named: 'Kernel'
  355. A package differs slightly from a Monticello package which can span multiple class categories using a naming convention based on hyphenation. But just as in Monticello a package supports "class extensions" so a package can define behaviors in foreign classes using a naming convention for method categories where the category starts with an asterisk and then the name of the owning package follows.
  356. You can fetch a package from the server:
  357. Package load: 'Additional-Examples'!

  544. ## API
  545. I have only one instance, accessed with class-side method `#current`.
  546. The `smalltalk` object holds all class and packages defined in the system.
  547. ## Classes
  548. Classes can be accessed using the following methods:
  549. - `#classes` answers the full list of Smalltalk classes in the system
  550. - `#at:` answers a specific class or `nil`
  551. ## Packages
  552. Packages can be accessed using the following methods:
  553. - `#packages` answers the full list of packages
  554. - `#packageAt:` answers a specific package or `nil`
  555. ## Parsing
  556. The `#parse:` method is used to parse Amber source code.
  557. It requires the `Compiler` package and the `js/parser.js` parser file in order to work.!
