WINTERP (Widget INTERPreter) is an application development environment developed at HP. It enables the rapid prototyping of graphical user-interfaces through direct manipulation of user interface objects and their attached actions. WINTERP provides an interface to the X11 toolkit (Xt) and the OSF/Motif widget set and a built-in RPC mechanism for inter-application communication. It includes an object-oriented 2.5D graphics and animation widget based on the Xtango path transition animation system, the XmGraph graph browser (with graph nodes as arbitrary WINTERP widgets), and GIF image support. The interpreter is based on David Betz's XLISP interpreter, which implements a small subset of Common Lisp and runs on PCs, Decstation 3100s, HP9000s, Sun3, Sparcs, SGI, and NeXT. XLISP provides a simple Smalltalk-like object system, with OSF/Motif widgets as real XLISP objects -- they can be specialized via subclassing, methods added or altered, etc. WINTERP includes an interface to GNU-Emacs which allows code to be developed and tested without leaving the editor. WINTERP is a free-standing Lisp-based tool for setting up window applications.
