5 Yassl: Scripting language

Yassl is yet another extensible scripting language to work with Java classes. New functions can be added to the language quickly, and as a demonstration I've created a set of functions that bundle some of the AWT functionality to create "widgetized" user interfaces.

Yassl and Javascript
Javascript is aimed at the HTML writer who wants to add programming functionality to a page. Yassl is useful for the Java programmer who wants to write user interfaces and applications more productively. Like Tcl does for C/C++ code, yassl provides a way to glue together java classes interactively.

There are links from here to demonstrations of its use. These demonstrations will load very slowly. The interpreter for the language is runnable as an applet, and these demos first download the interpreter and then run it.

Finally, all this is work in progress, and you will likely come upon rough edges periodically. Give me feedback, play with it, and if there is interest I'll continue to make it better. And without furthur ado, on to the fun stuff.
