+The macros in the maze, hanoi and urm directories can be used to test Vim for
+vi compatibility.  They have been written for vi to show its unlimited
+possibilities.	The life macros can be used for performance comparisons.
+
+hanoi	Macros that solve the tower of hanoi problem.
+life	Macros that run Conway's game of life.
+maze	Macros that solve a maze (amazing!).
+urm	Macros that simulate a simple computer: "Universal Register Machine"
+
+
+
+The other files contain some handy utilities.  They also serve as examples for
+how to use Vi and Vim functionality.
+
+less.sh + less.vim	make Vim work like less (or more)
+
+
+
+The following have been moved to an optional package.  Add the command to your
+vimrc file to use the package:
+
+packadd! dvorak		" Dvorak keyboard support; adds mappings
+
+packadd! editexisting	" when editing a file that is already edited with
+			" another Vim instance, go to that Vim instance
+
+packadd! justify	" justifying text.
+
+packadd! matchit	" makes the % command work better
+
+packadd! shellmenu	" menus for editing shell scripts in the GUI version
+
+packadd! swapmouse	" swap left and right mouse buttons

+Subject: VI SOLVES HANOI
+Message-ID: <2323@otc.otca.oz>
+Date: 19 Feb 91 01:32:14 GMT
+Sender: news@otc.otca.oz

+Archive-name: hanoi.vi.macros/part01
+
+Everyone seems to be writing stupid Tower of Hanoi programs.
+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 easily changed by editing
+the macro file.
+
+The disks aren't actually shown in this version, only numbers representing
+each disk, but I believe it is possible to write some macros to show the
+disks moving about as well. Any takers?
+
+(For maze solving macros, see alt.sources or comp.editors)
+

+" Macros to play Conway's Game of Life in vi
+" Version 1.0m: edges wrap
+" by Eli-the-Bearded Benjamin Elijah Griffin <vim@eli.users.panix.com>
+" Sept 1996
+" This file may be free distributed so long as these credits remain unchanged.
+"
+" Modified by Bram Moolenaar (Bram@vim.org), 1996 Sept 10
+" - Made it quite a bit faster, but now needs search patterns in the text
+" - Changed the order of mappings to top-down.
+" - Made "g" run the whole thing, "C" run one generation.
+" - Added support for any uppercase character instead of 'X'
+"
+" Rules:
+"   If a germ has 0 or 1 live neighbors it dies of loneliness
+"   If a germ has 2 or 3 live neighbors it survives
+"   If a germ has 4 to 8 live neighbors it dies of starvation
+"   If an empty box has 3 live neighbors a new germ is born
+"
+"   A new born germ is an "A".	Every generation it gets older: B, C, etc.
+"   A germ dies of old age when it reaches "Z".
+"
+" Notice the rules do not mention edges. This version has the edges wrap
+" around. I have an earlier version that offers the option of live edges or
+" dead edges. Email me if you are interested. -Eli-
+"
+" Note: This is slow!  One generation may take up to ten minutes (depends on
+" your computer and the vi version).
+"
+" Quite a lot of the messy stuff is to work around the vi error "Can't yank
+" inside global/macro".  Still doesn't work for all versions of vi.
+"
+" To use these macros:
+"
+" vi		start vi/vim
+"
+" :so life.mac	Source this file
+"
+" g		'g'o!  runs everything until interrupted: "IR".
+"
+" I		Initialize everything. A board will be drawn at the end
+"		of the current buffer. All line references in these macros
+"		are relative to the end of the file and playing the game
+"		can be done safely with any file as the current buffer.
+"
+"	Change the left field with spaces and uppercase letters to suit
+"	your taste.
+"
+" C		'C'ompute one generation.
+" +		idem, time running one generation.
+" R		'R'un 'C'ompute until interrupted.
+" i<nr><Esc>z	Make a number the only thing on the current line and use
+"		'z' to time that many generations.
+"
+" Time to run 30 generations on my 233 AMD K6 (FreeBSD 3.0):
+"   vim   5.4 xterm	51 sec
+"   gvim  5.4 Athena	42 sec
+"   gvim  5.4 Motif	42 sec
+"   gvim  5.4 GTK	50 sec
+"   nvi   1.79 xterm	58 sec
+"   vi	  3.7 xterm	2 min 30 sec
+"   Elvis 2.1 xterm	7 min 50 sec
+"   Elvis 2.1 X11	6 min 31 sec
+"
+" Time to run 30 generations on my 850 AMD Duron (FreeBSD 4.2):
+"   vim   5.8   xterm    21 sec
+"   vim   6.0   xterm    24 sec
+"   vim   6.0   Motif    32 sec

+To run the maze macros with Vim:
+
+	vim -u maze_mac maze_5.78
+	press "g"
+
+The "-u maze.mac" loads the maze macros and skips loading your .vimrc, which
+may contain settings and mappings that get in the way.
+
+
+The original README:
+
+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"
+Thanks to John Tromp (tromp@piring.cwi.nl) for maze.c.
+Thanks to antonyc@nntp-server.caltech.edu (Bill T. Cat) for maze.ansi.c.

+" These macros 'solve' any maze produced by the a-maze-ing maze.c program.
+"
+" First, a bit of maze theory.
+" If you were put into a maze, a guaranteed method of finding your way
+" out of the maze is to put your left hand onto a wall and just keep walking,
+" never taking your hand off the wall. This technique is only guaranteed to
+" work if the maze does not have any 'islands', or if the 'exit' is on the
+" same island as your starting point. These conditions hold for the mazes
+" under consideration.
+"
+" Assuming that the maze is made up of horizontal and vertical walls spaced
+" one step apart and that you can move either north, south, east or west,
+" then you can automate this procedure by carrying out the following steps.
+"
+" 1. Put yourself somewhere in the maze near a wall.
+" 2. Check if you have a wall on your left. If so, go to step 4.
+" 3. There is no wall on your left, so turn on the spot to your left and step
+"    forward by one step and repeat step 2.
+" 4. Check what is directly in front of you. If it is a wall, turn on the
+"    spot to your right by 90 degrees and repeat step 4.
+" 5. There is no wall in front of you, so step forward one step and
+"    go to step 2.
+"
+" In this way you will cover all the corridors of the maze (until you get back
+" to where you started from, if you do not stop).
+"
+" By examining a maze produced by the maze.c program you will see that
+" each square of the maze is one character high and two characters wide.
+" To go north or south, you move by a one character step, but to move east or
+" west you move by a two character step. Also note that in any position
+" there are four places where walls could be put - to the north, to the south,
+" to the east and to the west.
+" A wall exists to the north of you if the character to the north of
+" you is a _ (otherwise it is a space).
+" A wall exists to the east of you if the character to the east of you
+" is a | (otherwise it is a .).
+" A wall exists to the west of you if the character to the west of you
+" is a | (otherwise it is a .).
+" A wall exists to the south of you if the character where you are
+" is a _ (otherwise it is a space).
+"
+" Note the difference for direction south, where we must examine the character
+" where the cursor is rather than an adjacent cell.
+"
+" If you were implementing the above procedure is a normal computer language
+" you could use a loop with if statements and continue statements,
+" However, these constructs are not available in vi macros so I have used
+" a state machine with 8 states. Each state signifies the direction you
+" are going in and whether or not you have checked if there is a wall on
+" your left.
+"
+" The transition from state to state and the actions taken on each transition
+" are given in the state table below.
+" The names of the states are N1, N2, S1, S2, E1, E2, W1, W2, where each letter
+" stands for a direction of the compass, the number 1 indicates that the we
+" have not yet checked to see if there is a wall on our left and the number 2
+" indicates that we have checked and there is a wall on our left.
+"
+" For each state we must consider the existence or not of a wall in a
+" particular direction. This direction is given in the following table.
+"
+" NextChar table:
+" state        direction       vi commands
+"  N1              W               hF
+"  N2              N               kF
+"  S1              E               lF
+"  S2              S               F
+"  E1              N               kF
+"  E2              E               lF

+"  W2              W               hF
+"
+" where F is a macro which yanks the character under the cursor into
+" the NextChar register (n).
+"
+" State table:
+" In the 'vi commands' column is given the actions to carry out when in
+" this state and the NextChar is as given. The commands k, j, ll, hh move
+" the current position north, south, east and west respectively. The
+" command mm is used as a no-op command.
+" In the 'next state' column is given the new state of the machine after
+" the action is carried out.

+"      W2                 .            hh          W1
+"
+"
+" Complaint about vi macros:
+" It seems that you cannot have more than one 'undo-able' vi command
+" in the one macro, so you have to make lots of little macros and
+" put them together.
+"
+" I'll explain what I mean by an example. Edit a file and
+" type ':map Q rXY'. This should map the Q key to 'replace the
+" character under the cursor with X and yank the line'.
+" But when I type Q, vi tells me 'Can't yank inside global/macro' and
+" goes into ex mode. However if I type ':map Q rXT' and ':map T Y',
+" everything is OK. I`m doing all this on a Sparcstation.
+" If anyone reading this has an answer to this problem, the author would
+" love to find out. Mail to gregm@otc.otca.oz.au.
+"
+" The macros:
+" The macro to run the maze solver is 'g'. This simply calls two other
+" macros: I, to initialise everything, and L, to loop forever running
+" through the state table.
+" Both of these macros are long sequences of calls to other macros. All
+" of these other macros are quite simple and so to understand how this
+" works, all you need to do is examine macros I and L and learn what they
+" do (a simple sequence of vi actions) and how L loops (by calling U, which
+" simply calls L again).
+"
+" Macro I sets up the state table and NextChar table at the end of the file.
+" Macro L then searches these tables to find out what actions to perform and
+" what state changes to make.
+"
+" The entries in the state table all begin with a key consisting of the
+" letter 's', the current state and the NextChar.  After this is the
+" action to take in this state and after this is the next state to change to.
+"
+" The entries in the NextChar table begin with a key consisting of the
+" letter 'n' and the current state. After this is the action to take to
+" obtain NextChar - the character that must be examined to change state.
+"
+" One way to see what each part of the macros is doing is to type in the
+" body of the macros I and L manually (instead of typing 'g') and see
+" what happens at each step.
+"
+" Good luck.
+"
+" Registers used by the macros:
+" s (State)        - holds the state the machine is in
+" c (Char)         - holds the character under the current position
+" m (Macro)        - holds a vi command string to be executed later
+" n (NextChar)     - holds the character we must examine to change state
+" r (Second Macro) - holds a second vi command string to be executed later

+Archive-name: maze_solving_vi_macros
+
+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|'.
+
+Save this article and unshar it. Then read maze.README.
+
+After studying these macros, anyone who cannot write an emacs emulator
+in vi macros should just curl up and :q!.
+
+Coming soon to a newsgroup near you: "Vi macros solve Tower of Hanoi",
+and a repost of the original "Turing Machine implemented in Vi macros"
+
+Anyone who has a version of these macros for edlin or nroff, please post.

+This is another proof that Vim is perfectly compatible with Vi.
+The URM macro package was written by Rudolf Koenig ("Rudi")
+(rudolf@koeniglich.de) for hpux-vi in August 1991.
+
+Getting started:
+
+type
+in your shell:	 vim urm<RETURN>
+in vim:		 :so urm.vim<RETURN>
+in vim:		 *	(to load the registers and boot the URM-machine :-)
+in vim:		 g	(for 'go') and watch the fun. Per default, 3 and 4
+			are multiplied. Watch the Program counter, it is
+			visible as a comma moving around.
+
+This is a "standard URM" (Universal register machine)  interpreter. The URM
+concept is used in theoretical computer science to aid in theorem proving.
+Here it proves that vim is a general problem solver (if you bring enough
+patience).
+
+The interpreter begins with register 1 (not 0), without macros and more-lines
+capability.  A dot marks the end of a program. (Bug: there must be a space
+after the dot.)
+
+The registers are the first few lines, beginning with a '>' .
+The program is the first line after the registers.
+You should always initialize the registers required by the program.
+
+Output register:	line 2
+Input registers:	line 2 to ...
+
+Commands:
+a<n>		increment register <n>
+s<n>		decrement register <n>
+<x>;<y>		execute command <x> and then <y>
+(<x>)<n>	execute command <x> while register <n> is nonzero
+. 		("dot blank")  halt the machine.
+
+Examples:
+
+Add register 2 to register 3:
+	(a2;s3)3.
+Multiply register 2 with register 3:
+	(a4;a5;s2)2; ((a2;s4)4; s3; (a1;a4;s5)5; (a5;s1)1)3.
+
+There are more (complicated) examples in the file examples.
+Note, undo may take a while after a division.
