JavaScript Open Scripting Architecture (OSA), (originally JavaScript for OSA, then JavaScript OSA, abbreviated further as JSOSA), is a freeware inter-process communication scripting language for the Macintosh computer.
JavaScript OSA uses the "core language" of the Mozilla implementation of the JavaScript programming language, (see SpiderMonkey). The language is used as an alternative to the AppleScript language. Its use is unrelated to web browser-based scripting. It can be seen as having a similar function to Microsoft's JScript .NET language on Windows machines, although there is no interoperability between the two languages' system-level scripting.
Description
The language is identical to Mozilla's core language, with extensions added via a Core object and a MacOS object. The MacOS object has methods for obtaining objects that are bound to applications. This is done via the AppleEvent messaging system, a part of the Macintosh's Open Scripting Architecture.
The language was first released in 2001, and was bundled with Late Night Software's flagship product, Script Debugger. In May 2005, a new "alpha" version of the language was made available for testing. This improved second version of the language was bundled with version 4 of Script Debugger. JavaScript OSA was eventually discontinued due to lack of interest{{cite web|title=Yosemite JavaScript for Automation Support|url=http://www.latenightsw.com/2014/yosemite-javascript-for-automation-support/|website=Late Night Software|access-date=March 22, 2015}} and was dropped from Script Debugger 5 in 2012.{{cite web|title=What's New in Script Debugger 5.0|url=http://www.latenightsw.com/sd5/whats-new-in-script-debugger-5/|website=Late Night Software|access-date=March 22, 2015}}
Alternatives
OS X Yosemite introduced JavaScript for Automation (JXA): system-wide support for scripting with JavaScript, built upon JavaScriptCore and the Open Scripting Architecture.{{cite web|title=JavaScript for Automation|url=http://www.macstories.net/linked/javascript-for-automation-on-os-x-yosemite/|website=MacStories|access-date=August 31, 2014}} It features an Objective-C bridge which enables entire Cocoa applications to be programmed in JavaScript.{{cite web|title=JavaScript for Automation Release Notes|url=https://developer.apple.com/library/prerelease/mac/releasenotes/InterapplicationCommunication/RN-JavaScriptForAutomation/index.html#//apple_ref/doc/uid/TP40014508|publisher=Apple, Inc.|access-date=August 31, 2014}}
