There are a number of alternatives, depending on your application. XEmacs is not a wordprocessor, and it is unlikely to become one any time soon. I don't think any of the developers have much interest in doing that, and creating a redisplay that could handle accurate positioning, pagination, and all the rest would have to be done from scratch. It would not be hard to produce something that allows you produce Memopad-quality printed output most of the time, and not too much harder to do as well as Memopad all the time. But I don't think there are very many Emacs users who care. Most people who use Emacs prefer to use a real text justifier like TeX or troff for camera-ready copy, HTML for web pages, and so on. If you really want WYSIWYG, use Word or Framemaker or one of the *nix compatibles. If you want a semi-realistic display in XEmacs of what LaTeX will do very nicely, you can use preview-latex or AUC-TeX and customize the faces they use. PSGML will do the same for *ML documents. And if you just want to do it in XEmacs (progn (make-face 'tr "Times-Roman") (set-face-font 'tr "-adobe-times-medium-r-normal--*-120-*-*-*-*-iso8859-15") (make-face 'hv "Helvetica") (set-face-font 'hv "-adobe-helvetica-medium-r-normal--*-120-*-*-*-*-iso8859-15") (let ((here (point)) tre hve) (insert "Times-Roman") (setq tre (make-extent here (point))) (set-extent-face tre (find-face 'tr)) (insert " ") (setq here (point)) (insert "Helvetica") (setq hve (make-extent here (point))) (set-extent-face hve (find-face 'hv)))) does the trick. (The Windows version of the font name would be more compact, but otherwise the code is the same.) Granted, it wouldn't be hard (merely tedious) to cook up a library to allow you to do that operation the same way that Memopad allows you to do it. Why do we make it so "hard"? Because that's not what XEmacs is for. Typically the more complex text processing tasks already involve setting extents to delimit logical units of text, so you don't need to make an extent, just grab the appropriate one. And logical units (such as emphasis or comment or docstring) can be shared among applications, so such common semantics typically already have faces associated with them. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
