A warm welcome is very encouraging. I'll check that file.
I know nothing about how it is done, yet, but still I have some
simple vision, correct me when I'm wrong:
- to have a working connection with background maxima, we need a
maxima buffer. This buffer (a list of %inputs) is not a part of
latex/LyX document, so it should be stored somewhere. I was
thinking about putting it into .tex (.lyx) file as a comment, with
some magic keyword, like following:
% LYX+MAXIMA buffer, do not edit by hand, START
%
% * [wxMaxima: input start ] */
% e1:ellipse : x^2/a^2+y^2/b^2=1;
% e2:line : A*(x-x0)+B*(y-y0)=0;
% /* [wxMaxima: input end ] */
%
% LYX+MAXIMA buffer, do not edit by hand, END
the first two characters (the "% ") are always stripped, the rest is
treated as-is: the maxima input file format.
- there could be a split-window with just the maxima input buffer.
- interesting parts from the maxima buffer would be copied into
latex/lyx document, by using some sort of referencing.
- plot2d/3d would generate .ps files, provided correct gnuplot
parameters to generate .ps files (which I happen to know).
Pictures generated in this way would be entered into document
structure in the same manner as the equations.
- compiling lyx+maxima document, would mean to do some preprocessing:
+ first execute the maxima buffer in fresh maxima session. This
would calculate stuff, and generate .ps files.
+ enter the referenced equations in their latest form (freshly
calculated) into their proper places in the latex document
+ then continue the normal compilation, like invoking pdflatex
or others.
my head is bulging with ideas, but the time is really short.
I'll check what you've told me, tell me more. Do not expect me to be fast.
