[MACTCL] ANN: aem 1.0, a lightweight mechanism for Tcl/Tk applications on Mac OS X to respond to Apple Events

[Kevin W. <kw...@co...>]

I have just released aem 1.0, a lightweight mechanism for Tcl/Tk 
applications on Mac OS X to respond to Apple Events

This package allows Tcl/Tk applications on Mac OS X to respond to 
arbitrary Apple Events, the Mac's system-level application IPC protocol. 
The Apple Events mechanism allows Mac applications to script other 
applications using the AppleScript language--to query them for data, 
execute commands, and similar functions--in a manner similar to COM 
scripting on Windows and shell scripting on Unix. The package differs 
from an older Apple Events package, TclAE 
(http://tclae.sourceforge.net/), which is a thin wrapper over tne entire 
Apple Event framework and is more low-level and complex. The aem package 
only provides a way for a Tcl application to respond to Apple Event 
queries sent to it by other processes, i.e. to make a Tcl application 
scriptable via AppleScript.

The aem package defines only a single command, aem::installeventhandler, 
which takes three parameters: an event class, an event ID, and a Tcl 
command. The event class and event ID are arbitrary four-character codes 
that are registered with the operating system via the 
installeventhandler command, and the Tcl command is the internal Tcl 
command that is executed when the application receives an Apple Event. 
Conceptually, the event class can be viewed as the application or 
developer's signature, while the event ID corresponds to specific 
commands it may execute.

The package can be downloaded from 
http://fossil.codebykevin.com/fossil.cgi/tk-components/timeline as part 
of the tk-components suite; see instructions there on how to download 
the library. It is released under Tcl's BSD-style license.

Thanks,
Kevin
