The new beta

The new beta

Hi, Hans
   I download the new beta context today. It seems have some problems
when deal with the metapost graphics. I test it with a small file,
use the s-pre-04.tex. when compile, it give error message likes:

(mpgraph.mp (/usr/local/teTeX/share/texmf/metapost/context/mp-tool.mp)
(/usr/local/teTeX/share/texmf/metapost/context/mp-page.mp)
(/usr/local/teTeX/share/texmf/metapost/context/mp-tool.mp)
! Missing parameter type; `expr' will be assumed.

                                    t col) = x1 := x3 := y1 := 0 tex\relax etex

?

                   t

                                      col) = x1 := x3 := y1 := 0 tex\relax etex

? 

I  think it may have some problem in supp-mps.tex with \writeMPgraphics macros.
I saw the mpgraph.mp and find taht in line 9 it is:

def triangle (expr wid,rot)(tex t col) = x1 := x3 := y1 := 0 tex\relax etex
;

but in s-pre-04.tex, the line is :

def triangle (expr wid,rot)(text col) = x1 := x3 := y1 := 0;

When I edit the mpgraph.mp so that it has the same line as that in s-pre-04.tex,
mpost works well.

You're right. I changed the tex .. etex recently to catch tex .. verbatimtex (was discussed at the context list). This problem can be solved by adding a space after 'tex' in the argument of the macros in supp-mps: 

\dowriteMPgraphicline##1##2tex \relax etex\MPend

\long\def\dodowriteMPgraphicline#1tex #2#3etex#4\MPend%

\immediate\write\MPwrite{#1tex \ascii etex}%

\dowriteMPgraphicline#4tex \relax etex\MPend

I'll upload a new beta later.
