" Macros to play Conway's Game of Life in vi " Version 1.0m: edges wrap " by Eli-the-Bearded Benjamin Elijah Griffin " 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. " iz 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 " nvi 1.79 xterm 29 sec " vi 3.7 xterm 32 sec " elvis 2.1.4 xterm 34 sec " " And now the macros, more or less in top-down order.
