Re: [Maxima-discuss] Writing low-level `dim-*' functions

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

Mi Matthias,

I've never used TeXmacs-Maxima, so this is just a guess...

I _guess_ that TeXmacs-Maxima displays its output cells by generating
the TeX code for them and then rendering that in some way, and to
change the TeX code that is generated for antideriv objects we just
need this (in Maxima - not in Lisp):

  format([args]) := apply(?format, append([false], args));
  texput(antideriv, antideriv_tex);
  antideriv_tex(o) :=
    block([fx,x,a,b], [fx,x,a,b]:args(o),
          format("\\left.~a\\right|_{~a=~a}^{~a=~a}",
                 tex1(fx), tex1(x),tex1(a), tex1(x),tex1(b)));

After that the result of:

   tex1(antideriv(f(x),x,a,b));

becomes:

   \left.f\left(x\right)\right|_{x=a}^{x=b}

Try this too:

   antideriv(f(x),x,a,b);

Cheers,
  Eduardo
