I realize that I have been guilty of this, but I wish that people would stop comparing the DM to Emacs. I don't know anyone who would think that the DM is more powerful than Emacs as an editor. Several people have stated very strong arguments for Emacs. I personally like it better than the DM. The strength the DM has over Emacs is that it is integrated into the environment and Emacs is not; the DM can be used anywhere on the Apollo screen -- Emacs cannot (yes, I know, you can run a shell from inside Emacs. But you still can't touch the command window). The same arguments can be made, though less strongly, for 'vi' over the DM, but the DM still has the same strength of integration. (BTW, SUNs do not have an integrated editor like either the DM or Emacs. Just the history substitutions of 'csh', and the 'again'-like mousing/scrolling/picking method). The only system that I know of that has an Emacs-like editor integrated into the system to the extent that the DM is, is Symbolics (as has been pointed out). And as has been pointed out, Zmacs is getting pretty slow. As I said to Ashwin Ram, if Emacs could be integrated to the same degree as the DM is, and remain as fast as the DM, I'd buy it immediately. Since it is not, I will use Emacs for editing large text files, and the DM for quick messages like this one and for command line editing. P.S. As far as 'cut and paste' between windows is concerned, the same package of Apollo GNUEmacs extensions that uses the GPR graphics also implements the 'cut' and 'paste' keys on the Apollo keyboard in Emacs to use the same paste buffers as when using those keys outside of Emacs. Therefore, you can cut and paste between separate Emacs windows, and also between Emacs windows and DM windows. .

And as has been pointed out, Zmacs is getting pretty slow. The TI Explorer (and LMI Lmabda) also have integrated emacs. Since they have not "improved" the window interface, they are still quite fast.

When I edit text, I want one set of mappings. When I'm programming, I want a different set; in fact, I want a different set for shell programming and C programming. I also want to be able to change the mappings in one text editing window and not another, and I don't want any of these changes to affect how my "shell" character mappings are affected. When DM can do this, it will be a useful editor. When I worked on Apollos, I chose to use vi because it didn't stick me with a single set of key bindings. -- David Elliott {decvax,ucbvax,ihnp4}!decwrl!mips!dce

The *real* reason(s) that Emacs is better than DM: 1) You don't need an Apollo to run it. 2) It's free. (Sort of.) If DM source code can be UUCP'd from someplace and ported to a Sun, I might be willing to reconsider. -- ------------------------------------------------------------------------------ Dave Mack (from Mack's Bedroom :<) McDonnell Douglas-Inco, Inc.
