I believe a revolution is coming, and troff will be the first against the wall (to be sacrificed). Troff will die because of the t in it's name -- "Typesetter". Typesetters are being replaced by laserprinters, which do a lot more. Take a look at the output language of ditroff sometime. Here are the only graphics objects in the language: lines, thick lines (berkeley), circles, arcs, ellipses, and splines. characters, fonts, font sizes. Ask yourself, (1) How do I shade objects with different patterns or continuous halftones? (2) How do I draw thick objects in general? (3) How do I label the y axis of a graph, using 90-degree rotated words? (4) How would I label the arcs in a network flow graph with rotated letters? (5) How would I draw a black box and then etch characters into it (in reverse video?) (6) How do I include halftone / binary / floyded images? (7) How do I superimpose graphics objects on top of each other? The macintosh (and postscript) have all these abilities. Troff has none. All you need is a program to create these quickdraw/postscript images, and then you may paste them into your favorite WYSWYG word processor (mine is MS-Word, but Writenow, Fullwrite, Wordperfect, or Macwrite work equally well), and print them out at full postscript (300+ dpi) resolution. Face it, troff is an elephant, which deserves respect, a gold watch, and retirement very soon. Troff is also missing some formatting niceties, such as the ability to wrap text around a picture, or lay out pages like PageMaker or other page layout programs. About the only thing troff does better than these word processors is typeset mathematics. MS-Word typesets mathematics in an ugly fashion. I have talked to some people at microsoft, and they are considering improving MS-Word mathematics in Macintosh Word 5.0. Most other macintosh word processors do no math at all, but you can "draw" equations with one of a half-dozen equation-formatting desk accessories and paste them in. Some of these do an excellent job. I believe TeX will survive longer because its equation-formatting and word-spacing ability is unparalleled. But it will eventually succomb to the WYSWYG revolution, or its equations will be incorporated into a WYSWYG editor. If you want to have "a text stream I can ftp to my friends", then you should think about postscript. Postscript makes a great archival medium, as long as you treat the postscript file like a piece of immutable preprinted paper. Why not mail that friend a postscript master, and he can print it out on most of the laser printers in the country. Don Gillies, Dept. of Computer Science, University of Illinois 1304 W.
