" 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.
