《Learning the vi editor》

docs

Documentation on vi, also some comp.editors postings.

macros

vi macros.

comp.editors

Various materials posted to comp.editors.

programs

Source code for vi clones for various platforms (and other programs). Take
things from here with caution, as much of it is out of date.

The docs and macros are the most interesting. The docs directory has a large
number of articles and references, ranging from beginner's guides, explanations
of bugs, quick references, and many short "how to" kinds of articles (e.g., how to
capitalize just the first letter of a sentence in vi). There's even a song about vi!

The macros directory has over 50 files in it that do different things. We mention
just three of them. (Files whose names end in .Z are compressed with the UNIX
compress program. They can be uncompressed with either uncompress or
gunzip.)

evi.tar.Z

An emacs "emulator." The idea behind it is to turn vi into a modeless
editor (one that is always in input mode, with commands done with control
keys). It is actually done with a shell script that replaces the EXINIT
environment variable.

hanoi.Z

This is perhaps the most famous of the unusual uses of vi; a set of macros
that solve the Towers of Hanoi programming problem. This program
simply displays the moves, it does not actually draw the disks. For fun, we
have reprinted it in the sidebar.

turing.tar.Z

This program uses vi to implement an actual Turing machine! It's rather
amazing to watch it execute the programs.

There are many, many more interesting macros, including Perl and RCS modes
and even a Word Star emulator.

" Everyone seems to be writing stupid Tower of Hanoiprograms.
" Well, here is the stupidest of them all: the hanoi solving" vi macros.
"
" Save this article, unshar it, and run uudecode on" hanoi.vi.macros.uu. This will give you the macro file" hanoi.vi.macros.
" Then run vi (with no file: just type "vi") and type:
" :so hanoi.vi.macros
" g" and watch it go.
"
" The default height of the tower is 7 but can be easilychanged" by editing the macro file.
"
" The disks aren't actually shown in this version, onlynumbers
" representing each disk, but I believe it is possible towrite
" some macros to show the disks moving about as well. Anytakers?

E.3 Tastes Great, Less Filling
We can't discuss vi as part of UNIX culture without acknowledging what is
perhaps the longest running debate in the UNIX community,[B] vi versus emacs.

[B] OK, it's really a religious war, but we're trying to be nice. (The other religious war, BSD vs. System V, was
settled by POSIX. System V won, although BSD received significant concessions. )

Discussions about which is better have cropped up on comp.editors (and other
newsgroups) for years and years. You will find summaries of some of these
discussions in the ftp archives described above. You will find pointers to more
recent versions on the web pages.

Some of the better arguments in favor of vi are:

which is derived from an earlier version of GNU emacs. Both have advantages
and disadvantages, and their own sets of devotees.[C]

[C] Who undoubtedly share a joint distaste for vi!
Second, while GNU emacs has always had vi-emulation packages, until recently,
they have not been very good. This has changed. The "viper mode" is reputed to
be an excellent vi emulation. It can serve as a bridge for learning emacs for those
who are interested in doing so.

To conclude, always remember that you are the final judge of a program's utility.
You should use the tools that make you the most productive, and for many tasks,
vi and its clones are excellent tools.

E.4 vi Quotes
Finally, here are some more vi quotes, courtesy of Bram Moolenaar, vim's author:

THEOREM: vi is perfect.

PROOF: VI in roman numerals is 6. The natural numbers less than 6 which divide
6 are 1, 2, and 3. 1 + 2 + 3 = 6. So 6 is a perfect number. Therefore, vi is
perfect.
