|
|
* This build of GCLI for Firefox comes from 4 bits of code:
|
|
* - prefix-gcli.jsm: Initial commentary and EXPORTED_SYMBOLS
|
|
* - console.js: Support code common to web content that is not part of the
|
|
* default firefox chrome environment and is easy to shim.
|
|
* - mini_require: A very basic commonjs AMD (Asynchronous Modules Definition)
|
|
* 'require' implementation (which is just good enough to load GCLI). For
|
|
* more, see http://wiki.commonjs.org/wiki/Modules/AsynchronousDefinition.
|
|
* This alleviates the need for requirejs (http://requirejs.org/) which is
|
|
* used when running in the browser. This code is provided by dryice.
|
|
* - A build of GCLI itself, packaged using dryice
|
|
* - suffix-gcli.jsm - code to require the gcli object for EXPORTED_SYMBOLS.
|
|
*
|
|
* See Makefile.dryice.js for more details of this build.

|
|
* This term is used because carries the notion of a work-flow, or process to

* getting the information to execute a command correct.
|
|
* There is little point in a requisition for parameter-less commands because
|
|
* there is no information to collect. A Requisition is a collection of

|
|
* <ul>
|
|
* <li>commandChange: The command has changed. It is likely that a UI
|
|
* structure will need updating to match the parameters of the new command.
|
|
* The event object looks like { command: A }
|
|
* <li>assignmentChange: This is a forward of the Assignment.assignmentChange
|
|
* event. It is fired when any assignment (except the commandAssignment)
|
|
* changes.
|
|
* <li>inputChange: The text to be mirrored in a command line has changed.
|
|
* The event object looks like { newText: X }.
|
|
* </ul>
|
|
*
|
|
* @param environment An opaque object passed to commands using ExecutionContext
