; $Header: /usr/build/vile/vile/macros/RCS/pictmode.rc,v 1.4 2005/04/19 19:21:59 tom Exp $
; this procedure implements a primitive ascii picture-drawing mode.
;		pgf, may '95

; motions are accomplished with the usual h, j, k, and l keys
; (the arrow keys do _not_ work here).  in addition, the u, i,
; n, and m keys will perform diagonal motions.  look at your
; keyboard to see why these were chosen.

; normally, entering the motion characters (h, j, k, l, u, i, n, m)
; will draw appropriate box outlines, using the -, |, /, and \ characters.

; lines will be drawn instead with a specific character if the 'c' command
; is given -- you will be prompted for a character.  this can be
; cancelled, to revert lines to their "natural" rendition, with the
; 'C' command.  for example, to draw with a '+' character, you would
; use "c+" and when finished, would cancel with "C".

; the ^T command will allow you to enter a string of text.  this
; text will accumulate until ESC, CR, or NL is typed.

; all other input will be inserted as-is, with no cursor movement.  so
; the space bar can be used to "erase" previously drawn stuff.

; space for the picture must be pre-allocated, with, for example:
;		80i <ESC>yy24p
;
; start this up with "run pic"
; to bind it to a key instead, change it to a "NN store-macro", and
; then bind "execute-macro NN" to the key you want.
