Good evening.
I apologize that I dare to post here such offtopic, but I feel this is
the right place to get an answer.
I try to write some general-purpose MetaPost macros for me with
ConTeXt-like interface. For instance, I'd like something like this:
label(point, "label=$A$, xlabel=$x_A$, ylabel=$y_A$,
ylabelshift=left, lines=no, dotstyle=bigdot, ...");
I've done a lot of work and it almost works, but ... I failed to notice
that TeX sequences are in normal cases included between btex ... etex
and are preprocessed. In other words, they cannot be typeset as a
string. I could use TEX macro, but it slows the process down in a
horrible way.
I think the best way is this: In the first run of MetaPost to flush out
all TeX codes, then process it with TeX (texexec), and then to include
it in the second MetaPost run. But I don't know how to do it? Can you
help me or at least hint where I could find an answer? And BTW, is this
a good idea at all? Isn't there a better/faster way?
Many thanks for you kind help.
