The program itself is much smaller. +GNU Emacs uses about 250k more pure storage. +As a result, Gosling Emacs can run on machines +that cannot run GNU Emacs. There is not much difference +in the amount of impure storage in the two programs. + +2. In some versions there is support for other forks to +establish communications channels to Emacs (using sockets?). + +3. There is a direct interface to dbm (data bases). + + +Advantages of GNU Emacs: + +* True Lisp, not Mocklisp. + +GNU Emacs's extension language has real symbols, lists +and vectors. Many extensions are much simpler, and some +become possible that were nearly impossible in Gosling Emacs. +Many primitives can have cleaner interfaces, and some features +need not be put in as special primitives because you can do +them easily yourself. + +* But Mocklisp still works. + +An automatic conversion package plus a run-time library +allows you to convert a Mocklisp library into a Lisp library. + +* Commands are better crafted. + +For example, nearly every editing function for which a +numeric argument would make sense as a repeat count does +accept a repeat count, and does handle a negative argument +in the way you would expect. + +* The manual is clearer. + +Everyone tells me it is a very good manual. + +* Better on-line documentation. + +Both functions and variables have documentation strings that +describe exactly how to use them. + +* C mode is smart. + +It really knows how to indent each line correctly, +for most popular indentation styles. (Some variables +control which style is used.) + +* Compatible with PDP-10 Emacs, Multics Emacs and Zmacs. + +The commands in GNU Emacs are nearly the same as in the +original Emacs and the other Emacses which imitated it. +(A few have been changed to fit the Unix environment better.) + +* Support for Gosling's Emacs commands. + +M-x set-gosmacs-bindings rebinds many editing commands for +compatibility with Gosling's Emacs. +M-x set-gnu-bindings reverses the change. + +* Side-by-side windows. + +You can split a GNU Emacs window either horizontally or +vertically. + +* Redisplay is faster. + +GNU Emacs sends about the same stuff to the terminal that +Gosling's does, but GNU Emacs uses much less CPU time to +decide what to do. + +* Entirely termcap-driven. + +GNU Emacs has nearly no special code for any terminal type. Various +new termcap strings make it possible to handle all terminals nearly as +fast as they could be handled by special-case code. + +* Display-hiding features. + +For example, Outline Mode makes it possible for you to edit +an outline, making entire sub-branches of the outline visible +or invisible when you wish. + +* You can interrupt with Control-G. + +Even a looping Lisp program can be stopped this way. +And even a loop in C code does not stop you from killing +Emacs and getting back to your shell. + +* Per-buffer Undo. + +You can undo the last several changes, in each buffer +independently. + +* The editor code itself is clean. + +Many people have remarked on how much they enjoy reading +the code for GNU Emacs. + + +One other note: The program etc/cvtmail that comes with GNU Emacs can +be used to convert a mail directory for Gosling Emacs's Rmail into a +Unix mail file that you could read into GNU Emacs's Rmail. + + +A detailed comparison by Rodney Zykowitz (rtgvax!ramin@eddie.mit.edu) + +Enclosed are two difference listings. The first one is a cross-reference +by Key bindings. The second is by alphabetized function name. +Only those functions normally bound to keys in a +"standard" version are included. As far as I know it excludes +bindings added here locally (but what do I know...) + +The Gosling's is version 2.02 and runs on VMS 4.2. The Gnu is +version 16.56.1 running under Ultrix 1.1. + + +And could someone send me some info on Gnu on VMS. I seem to have entirely +missed that posting. If it is hopeless, I just might sit down and write +a Gnu emulator for Unipress and a Unipress emulator for Gnu... But the +thought of that already makes me wanna.... + + +ramin... +Standard disclaimer excluded for humanitarian purposes. + + + +Command Binding Cross-references.
