Hello, list!
I am writing down a macro package for commutative diagrams using metafun.
This is my first try:
https://bitbucket.org/andrecaldas/math-video-classes/src/9a050eab20348c9a9c9e50740618173648979f45/src/environments/diagrams.tex?at=default
Used here:
https://bitbucket.org/andrecaldas/math-video-classes/src/9a050eab2034/src/products/assorted/open_mapping_theorem/notes/introduction.tex?at=default#cl-106
But I would like to use some "object oriented" like approach. That is,
I'd like the diagram data structure to be set up like this:
d = CD.new;
d.vertex("$X$"); d.arrow("$f$"); d.vertex("$Y$");
d.newline;
d.arrow("$\pi$"); d.arrow("$\pi$");
d.vertex("$A$"); d.arrow("$g$"); d.vertex("$B$");
or even in some "thelabel" similar fashion,
d = CD.new;
CD.vertex(d, "$X$"); CD.arrow(d, "$f$"); CD.vertex(d, "$Y$");
CD.newline(d);
CD.arrow(d, "$\pi$"); CD.arrow(d, "$\pi$");
CD.vertex(d, "$A$"); CD.arrow(d, "$g$"); CD.vertex(d, "$B$");
How do I do that in METAFUN/METAPOST?
Cheers,
André Caldas.

I have done some OOP like coding...

This is my first METAFUN experience. Comments are very welcome!

You may want to take a look at my attempt:
http://users.dimi.uniud.it/~nicola.vitacolonna/home/content/metappeal
It is a library intended to provide a minimal framework for “oo-like” constructs.
It is a work in progress (actually, I have not worked on it for a while since I
didn't receive any feedback) and the documentation is a bit messy, but the core
is stable and well tested and should be compatible with MetaFun.
It is all based on a pair of macros that generalize MetaPost declarations, a
first draft of which is shortly described here:
http://oldwww.gust.org.pl/projects/pearls/2011p/index_html
For the functionality you are describing, you may just need to grab the file
metappeal.mp (and the files that it includes) and include it in your source.
Nicola
