Another system to consider is the Andrew Toolkit (ATK), its ez editor, and its suite of applications which share the same data formats and user interfaces. ATK generates troff code and documents may be augmented with embedded troff code if you want. It handles and displays various fonts, type sizes and face variants, justification, centered and right flush, sub- and superscript, indentation, explicit page breaks, footnotes.... The major feature is the capability of embedding objects in text--rasters, tables, equations, drawings, ...; this is an open system so users can create their own objects and embed them. For printing, ATK generates troff (with embedded postscript for rasters) which is run through troff (and psdit) to print the document. ATK is WYSIWYG only to the extent of showing all typography and embedded objects; line breaks on the display are adjusted to the display width. Lineand page breaks for printing are deferred to troff with its extensive knowledge of the exact fonts that will be used for printing, but the printed form can be viewed before printing via the 'preview' program. (Looking at a preview image shows one reason why WYSIWYG is not always a great idea; characters positioned on screen according to their print widths look awful.) NESS "Ness" is the extension language for ATK. It is a general purpose language with an emphasis on extending the behavior of embedded objects. String processing is especially well supported: fromrtf.n, a translator from RTF to ATK, is fully-functioned, and yet only 2600 lines long. String values in Ness can contain all the typographic formatting and embedded objects supported by ATK. The cost of ATK has an upside and a downside. It is free, so the price is reasonable. But it is not a "product" so some features are not fully implemented. I find it satisfactory for my work and have written half a dozen papers and thousands of lines of code using it over the past four years. (Among the ATK applications is the multi-media mail interface with which I am writing this note.) ATK is available on the X tape and from the various ftp sites that provide X--under directory contrib/andrew. Our own ftp site is emsworth.andrew.cmu.edu (128.2.30.62).
