[Maxima-discuss] verbatimmatrix

[Eduardo O. <edu...@gm...>]

Hi list,

I found a way to write the display code for `verbatimmatrix'es, that,
very roughly, are `matrix'es of strings without the outer brackets and
without interline spacings. My code is here,

  https://anggtwu.net/MAXIMA/dim-verbatimbox.lisp.html
  https://anggtwu.net/MAXIMA/dim-verbatimbox.lisp

and the part that is going to be more useful to other people is the
part of the comments that explain that in the display code lists like
these one

   ((3 0)
    (-2 -2 #\g)
    (-4 -1 #\f #\e)
    (0 0 #\d #\c #\b #\a))

are to be read by humans as:

  Start at (x,y)=(0,0). Typeset "abcd". Now (x,y)=(4,0).
  Move by x+=-4, y=-1. Now (x,y)=(0,-1). Typeset "ef". Now (x,y)=(2,-1).
  Move by x+=-2, y=-2. Now (x,y)=(0,-2). Typeset "g". Now (x,y)=(1,-2).
  Move by x+=3, y=0. Now (x,y)=(4,0), and we're after the "d" of the "abcd".

I'm attaching a screenshot and a copy of the current version of code
for reference, but the htmlized version in

  https://anggtwu.net/MAXIMA/dim-verbatimbox.lisp.html
  https://anggtwu.net/MAXIMA/dim-verbatimbox.lisp

is much better becase its Eduardisms are explained by hyperlinks.
Cheers =),
