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things from here with caution, as much of it is out of date.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.
