To prove that you can do anything in vi, I wrote a couple of macros that
allows vi to solve mazes. It will solve any maze produced by maze.c
that was posted to the net recently.

Just follow this recipe and SEE FOR YOURSELF.
1. run uudecode on the file "maze.vi.macros.uu" to
produce the file "maze.vi.macros"
(If you can't wait to see the action, jump to step 4)
2. compile maze.c with "cc -o maze maze.c"
3. run maze > maze.out and input a small number (for example 10 if
you are on a fast machine, 3-5 if slow) which
is the size of the maze to produce
4. edit the maze (vi maze.out)
5. include the macros with the vi command:
:so maze.vi.macros
6. type the letter "g" (for "go") and watch vi solve the maze
7. when vi solves the maze, you will see why it lies
8. now look at maze.vi.macros and all will be revealed

Tested on a sparc, a sun and a pyramid (although maze.c will not compile
on the pyramid).

Anyone who can't get the maze.c file to compile, get a new compiler,
try maze.ansi.c which was also posted to the net.
If you can get it to compile but the maze comes out looking like a fence
and not a maze and you are using SysV or DOS replace the "27" on the
last line of maze.c by "11"

The macros in the maze and hanoi directories can be used to test Vim for
vi compatibility. They have been written for vi to show its unlimited
possibilities.

HANOI are macros that solve the tower of hanoi problem.
MAZE are macros that solve a maze (amazing!).

They are unmodified.


The other files contain some handy macros:

center: center current line in 80-character line
keyword: keyword completion
README for version 2.0 of Vim: Vi IMproved.

Vim is an almost compatible version of the UNIX editor vi. Only the 'Q'
command is missing (you don't need it). Many new features have been added:
multi level undo, command line history, filename completion, block operations,
etc. See difference.doc.

This editor is very useful for editing programs and other plain ASCII files.
All commands are given with normal keyboard characters, so those who can type
with ten fingers can work very fast. Additionally function keys can be defined
by the user.

Vim currently runs under Amiga DOS, MSDOS and many UNIX versions. Porting to
other systems should not be very difficult.

Documentation:
tutor/readme - one hour training course for beginners
reference.doc - complete reference of all Vim commands
difference.doc - summarizes the differences with UNIX vi
index - alfabetical list of commands
amiga.doc - remarks for Amiga
unix.doc - remarks for unix
msdos.doc - remarks for MSDOS

Vim is Charityware. You can copy it as much as you like. Please read
uganda.txt for details.


The makefile offers some compilation options. If you do not use digraphs, you
can save some memory by recompiling without the DIGRAPHS option. The Amiga
and MS-DOS versions are compiled for a limited number of supported terminals.
If you want to use Vim with other terminals you can recompile with the
TERMCAP option. See the makefiles for further options.

Vitutor is a "hands on" tutorial for new users of the Vim editor.

Most new users can get through it in less than one hour. The result
is that you can do a simple editing task using the Vim editor.

Tutor is a file that contains the tutorial lessons. You can simply
execute "vim tutor" and then follow the instructions in the lessons.
The lessons tell you to modify the file, so DON'T DO THIS ON YOUR
ORIGINAL COPY.

I have considered adding more advanced lessons but have not found the
time. Please let me know how you like it and send any improvements you
make.
