1.1 root 1: Advantages of Gosling Emacs:
2:
3: 1. The program itself is much smaller.
4: GNU Emacs uses about 250k more pure storage.
5: As a result, Gosling Emacs can run on machines
6: that cannot run GNU Emacs. There is not much difference
7: in the amount of impure storage in the two programs.
8:
9: 2. In some versions there is support for other forks to
10: establish communications channels to Emacs (using sockets?).
11:
12: 3. There is a direct interface to dbm (data bases).
13:
14:
15: Advantages of GNU Emacs:
16:
17: * True Lisp, not Mocklisp.
18:
19: GNU Emacs's extension language has real symbols, lists
20: and vectors. Many extensions are much simpler, and some
21: become possible that were nearly impossible in Gosling Emacs.
22: Many primitives can have cleaner interfaces, and some features
23: need not be put in as special primitives because you can do
24: them easily yourself.
25:
26: * But Mocklisp still works.
27:
28: An automatic conversion package plus a run-time library
29: allows you to convert a Mocklisp library into a Lisp library.
30:
31: * Commands are better crafted.
32:
33: For example, nearly every editing function for which a
34: numeric argument would make sense as a repeat count does
35: accept a repeat count, and does handle a negative argument
36: in the way you would expect.
37:
38: * The manual is clearer.
39:
40: Everyone tells me it is a very good manual.
41:
42: * Better on-line documentation.
43:
44: Both functions and variables have documentation strings that
45: describe exactly how to use them.
46:
47: * C mode is smart.
48:
49: It really knows how to indent each line correctly,
50: for most popular indentation styles. (Some variables
51: control which style is used.)
52:
53: * Compatible with PDP-10 Emacs, Multics Emacs and Zmacs.
54:
55: The commands in GNU Emacs are nearly the same as in the
56: original Emacs and the other Emacses which imitated it.
57: (A few have been changed to fit the Unix environment better.)
58:
59: * Support for Gosling's Emacs commands.
60:
61: M-x set-gosmacs-bindings rebinds many editing commands for
62: compatibility with Gosling's Emacs.
63: M-x set-gnu-bindings reverses the change.
64:
65: * Side-by-side windows.
66:
67: You can split a GNU Emacs window either horizontally or
68: vertically.
69:
70: * Redisplay is faster.
71:
72: GNU Emacs sends about the same stuff to the terminal that
73: Gosling's does, but GNU Emacs uses much less CPU time to
74: decide what to do.
75:
76: * Entirely termcap-driven.
77:
78: GNU Emacs has nearly no special code for any terminal type. Various
79: new termcap strings make it possible to handle all terminals nearly as
80: fast as they could be handled by special-case code.
81:
82: * Display-hiding features.
83:
84: For example, Outline Mode makes it possible for you to edit
85: an outline, making entire sub-branches of the outline visible
86: or invisible when you wish.
87:
88: * You can interrupt with Control-G.
89:
90: Even a looping Lisp program can be stopped this way.
91: And even a loop in C code does not stop you from killing
92: Emacs and getting back to your shell.
93:
94: * Per-buffer Undo.
95:
96: You can undo the last several changes, in each buffer
97: independently.
98:
99: * The editor code itself is clean.
100:
101: Many people have remarked on how much they enjoy reading
102: the code for GNU Emacs.
103:
104:
105: One other note: The program etc/cvtmail that comes with GNU Emacs can
106: be used to convert a mail directory for Gosling Emacs's Rmail into a
107: Unix mail file that you could read into GNU Emacs's Rmail.
108:
109:
110: A detailed comparison by Rodney Zykowitz ([email protected])
111:
112: Enclosed are two difference listings. The first one is a cross-reference
113: by Key bindings. The second is by alphabetized function name.
114: Only those functions normally bound to keys in a
115: "standard" version are included. As far as I know it excludes
116: bindings added here locally (but what do I know...)
117:
118: The Gosling's is version 2.02 and runs on VMS 4.2. The Gnu is
119: version 16.56.1 running under Ultrix 1.1.
120:
121:
122: And could someone send me some info on Gnu on VMS. I seem to have entirely
123: missed that posting. If it is hopeless, I just might sit down and write
124: a Gnu emulator for Unipress and a Unipress emulator for Gnu... But the
125: thought of that already makes me wanna....
126:
127:
128: ramin...
