For some unknown reason, the WINTERP BOF was scheduled to occur at the same time, and same date as the LISP BOF. This is unfortunate since there is a strong intersection of interests between the two BOF's. WINTERP (please don't pronounce it WINTER-PEE unless you like yellow snow :-) is a Widget INTERPreter that uses XLISP and the XLISP object system to provide a high-level, fully interactive interface to the OSF/Motif widget set. WINTERP is useful as an application prototyping environment -- I use it to interactively create widget-based graphical UIs for programs in the same way that people use gnuemacs to create text-based interfaces. WINTERP can also be embedded in applications requiring end-user tailoring of the application functionality and extension of the application user interface. The WINTERP BOF will be of interest to: (1) People interested in Motif bindings to Lisp. (2) People interested in UI languages with object orientation (WINTERP allows Motif widgets to be subclassed and extended within the language). (3) People interested in delivering hybrid programs that consist mostly of C (for efficiency & speed), with an embedded lightweight Lisp interpreter as a prototyping/extension language. (4) Those believing that Common Lisp is not a suitable platform for delivering portable applications with good multiprocessing performance on Unix workstations. For more information, here's the blurb announcing the WINTERP BOF: -------------------- Subject: WINTERP B.O.F. at 5th Annual Tech. Conf. on the X Window System I'm posting this note to announce that there will be an informal "birds of a feather" session on the WINTERP OSF/Motif Widget INTERPreter at the upcoming 5th Annual Tech. Conf. on the X Window System. The conference is happening at the Boston Marriott Copley Place in Boston, Massachusetts, 14-16 January 1991. I figured that since I'm attending this conference, I might as well get together with any current or prospective WINTERP users. The BOF will be held on Tuesday, January 15 8:00 PM to 9:30 PM. In the "Provincetown/Orleans room" of the Mariott. I'd like to use this session as an informal information exchange: * For interested folks to find out more about WINTERP. * To get input on desired features and improvements. * Discuss upcoming plans for WINTERP (e.g. the real soon now WINTERP 1.1 // Motif 1.1 release) * Exchange ideas on how people are using WINTERP for application prototyping. * Find out how people are using WINTERP as a platform for building customizable/extensible applications. * Discuss issues: WINTERP vs. UIL, WCL, Tcl, Builders, UIMSs, etc. * etc. If you are planning on attending, please reply by e-mail to mayer@hplabs.hp.com (or {decwrl,sun,etc}hplabs!mayer). If you want, you may also suggest further topics for discussion. PS: for further info on WINTERP, see the proceedings of Xhibition '90 (pls ignore formatting and spelling errors introduced by ICS), or see the proceedings of the EXUG First European X Conference (Sept 1990). PPS: The following is a blurb introducing WINTERP and telling you how to get this software: -------------------- WINTERP: An object-oriented rapid prototyping, development and delivery environment for building user-customizable applications with the OSF/Motif UI Toolkit. ------------------------------------------------------------------------------ WINTERP is a Widget INTERPreter, an application development environment enabling rapid prototyping of graphical user-interfaces (GUI) through the interactive programmatic manipulation of user interface objects and their attached actions. The interpreter, based on David Betz's XLISP, provides an interface to the X11 toolkit Intrinsics (Xtk), the OSF/Motif widget set, primitives for collecting data from UN*X processes, and facilities for interacting with other UN*X processes. WINTERP thus supports rapid prototyping of GUI-based applications by allowing the user to interactively change both the UI appearance and application functionality. These features make WINTERP a good tool for learning and experimenting with the capabilities of the OSF/Motif UI toolkit, allowing UI designers to more easily play "what if" games with different interface styles. WINTERP is also an excellent platform for delivering extensible or customizable applications. By embedding a small, efficient language interpreter with UI primitives within the delivered application, users and system integrators can tailor the static and dynamic layout of the UI, UI-to-application dialogue, and application functionality. WINTERP's use of a real programming language for customization allows WINTERP-based applications to be much more flexible than applications using customization schemes provided by the X resource database or OSF/Motif's UIL (user interface language). An environment similar to WINTERP's already exists in the Gnu-Emacs text editor -- WINTERP was strongly influenced by Gnu-Emacs' successful design. In Gnu-Emacs, a mini-Lisp interpreter is used to extend the editor to provide text-browser style interfaces to a number of UN*X applications (e.g. e-mail user agents, directory browsers, debuggers, etc). Whereas Emacs-Lisp enables the creation of new applications by tying together C-implemented primitives operating on text-buffer UI objects, WINTERP-Lisp ties together operations on graphical UI objects implemented by the Motif widgets. Both achieve a high degree of customizability that is common for systems implemented in Lisp, while still attaining the speed of execution and (relatively) small size associated with C-implemented applications. Other features: * WINTERP is free software -- available via anonymous ftp from expo.lcs.mit.edu:contrib/winterp/winterp-1.01.tar.Z * Portable -- runs without porting on many Unix systems. * Interface to gnuemacs' lisp-mode allows code to be developed and tested without leaving the editor; * Built-in RPC mechanism for inter-application communications; * XLISP provides a simple Smalltalk-like object system. * OSF/Motif widgets are real XLISP objects -- widgets can be specialized via subclassing, methods added or altered, etc. * Automatic storage management of Motif/Xt/X data. * Contains facilities for "direct manipulation" of UI components; You may obtain the current source, documentation, and examples via anonymous ftp from host expo.lcs.mit.edu: in directory contrib/winterp you will find the compress(1)'d tar(1) file winterp-1.01.tar.Z. Slides, papers and further documentation can be found in directory contrib/winterp/papers. There is also a mailing list for WINTERP-related announcements and discussions.
