A real working model. See it walk the maze in front of your very own eyes.
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 alt.sources last month. (Maze.c is also included
in this posting as well as an example of its output.)
The uncommented version of the macros was sent to alt.sources last month.
However, so many people mailed me requesting the commented version of the
macros that I decided to post it. I have made some modifications to the
original macros to make them easier to follow and also after I learnt
that you can escape the special meaning of '|' in macros by using '^V|'.
After studying these macros, anyone who cannot write an emacs emulator
in vi macros should just curl up and :q!.

XTo prove that you can do anything in vi, I wrote a couple of macros that
Xallows vi to solve mazes. It will solve any maze produced by maze.c
Xthat was posted to the net recently.
X
XJust follow this recipe and SEE FOR YOURSELF.
X 1. run uudecode on the file "maze.vi.macros.uu" to
X produce the file "maze.vi.macros"
X (If you can't wait to see the action, jump to step 4)
X 2. compile maze.c with "cc -o maze maze.c"
X 3. run maze > maze.out and input a small number (for example 10 if
X you are on a fast machine, 3-5 if slow) which
X is the size of the maze to produce
X 4. edit the maze (vi maze.out)
X 5. include the macros with the vi command:
X :so maze.vi.macros
X 6. type the letter "g" (for "go") and watch vi solve the maze
X 7. when vi solves the maze, you will see why it lies
X 8. now look at maze.vi.macros and all will be revealed
X
XTested on a sparc, a sun and a pyramid (although maze.c will not compile
Xon the pyramid).
X
XAnyone who can't get the maze.c file to compile, get a new compiler,
Xtry maze.ansi.c which was also posted to the net.
XIf you can get it to compile but the maze comes out looking like a fence
Xand not a maze and you are using SysV or DOS replace the "27" on the
Xlast line of maze.c by "11"
XThanks to John Tromp (tromp@piring.cwi.nl) for maze.c.
XThanks to antonyc@nntp-server.caltech.edu (Bill T. Cat) for maze.ansi.c.
X
XAny donations should be in unmarked small denomination bills :^)=.
