I have browsed mptopdf.pl code and I have discovered that I can process
my original example with
mptopdf --rawmp --metafun example.mp
(en passant, it would be nice if 'mptopdf --help' showed the available
options).
The script recognizes when LaTeX is being used (lines 78--84), but
unless --rawmp is given, it processes the file with texexec (which, as
far as I have understood, does not currently work correctly with LaTeX,
even if it probably should).
It has turned out that the combination mptopdf/latex seems quite an
unusual one: apparently, a ConTeXt user does not need to care about
LaTeX stuff (of course); on the other hand, a LaTeX user might want to
include the powerful MetaFun macros in raw MetaPost files (that was my
case), without using ConTeXt. The latter can be accomplished as shown
above, which implies
mpost --tex=latex --progname=mpost --mem=metafun
So, why not change mptopdf.pl so that it uses the command above when the
latex switch is present and texexec only when there is no LaTeX related
stuff? That is, change lines 86-100 to read:
if ($Latex) { # Use mpost + metafun macros
$mpbin = "mpost --tex=latex --progname=mpost --mem=metafun" ;
} else {
$mpbin = "texexec --mptex $PassOn" ;
}
The rationale here is that, probably, the more complicated processing by
texexec is not relevant to the LaTeX user.
My other question was: is page 5, ?1 in metafun-p.pdf obsolete? As I
have already pointed out, 'input mp-tool; input mp-spec;' at the
beginning of my original example results in no errors, but the output
has a blank figure. Or is this a question for the metapost mailing list?
