Open Scripting Architecture(OSA) - Extensions

There are many very useful OSA extensions - libraries of functions, that can be put to very good use when creating AppleScript Applets. OSAXEN by the way are not restricted to use by AppleScript. Any OSA compliant language, and unfortunately you can count them on the fingers of one hand, can make use of OSAXEN.

Here is a list of some and from where you can download them. Some of these may "break" in a 64-bit Mac OS X system in Leopard(10.5) and in Snow Leopard(10.6) . One possible workaround is to go to the Information panel(select the icon and press command-I) and force execution in 32-bit mode. They could all be placed in the System/Library/ScriptingAdditions folder so that all users have direct access. You may need to provide an administrator name and password to do this. To access their dictionary just double-click the icon. OSAXEN generally have the file extension .osax . In some cases, also .app in which case a tell(context) wrapper is required.
