Hi,
Something goes wrong while using metaobj and point something along
somepath. I do not know if point ... along... is a mp core command or
something introduced by metafun. Is this metafun's fault, metaobj's
fault or simply a metapost issue (and thus I should ask on the
metapost list).
\setupcolors
[state=start]
\startMPinclusions
input metaobj;
\stopMPinclusions
% Everything works fine if I comment metaobj.
\starttext
\startMPpage
path p ; p := (0,0)--(1cm,0) ;
draw p
withpen pencircle scaled 2bp
withcolor 0.8white;
draw (point .25 along p)--(point .75 along p)
withpen pencircle scaled 2bp
withcolor red ;
\stopMPpage
\stoptext
gives
! Missing argument to arctime.
<to be read again>
of
along->(arctime((EXPR0)*(arclength(EXPR1)))of
(EXPR1))of(EXPR1)
<to be read again>
)
l.295 draw (point .25 along p)
--(point .75 along p)

It is Metaobj's fault, it redefines (and therefore blocks access to)
the primitive command arctime. So I guess you should complain to
Denis Roegel (at the very least he should save the primitive arctime
under a different name). A workaround (I think) is this:
input metaobj;
primarydef pct along pat =
arctime (pct,pat) of pat
enddef ;

To all,
I am the author of a physics booklet written in LATEX+PsTRICKS.
Now, my I intend is to make one improved version in Context, but I
have many
schems with PSTRICKS commands. Did you know a easy way to make the
migration?
Thanks a lot
Jorge

there is a module, m-pstric.tex
\usemodule[pstrick]
\startPSTRICKS
\pspicture(0,0)(10,10)
\dorecurse{10}{\psline(0,0)(\recurselevel,10)}
\dorecurse{10}{\psline(0,0)(10,\recurselevel)}
\endpspicture
\stopPSTRICKS
an option is to put the graphics in separate files and/or use checksum trickery as used in m-r (not yet done)

Thanks.
But, in this LATEX_to_Context migration, I need to convert at hand
several latex commands. For example:
\begin{itemize} to \startitemize
\end{itemize} to \stopitemize
\begin{table}_to_\starttable
and so on.
this is a very hard task.
Perhaps I need to make: perl -ps 's/\begin{itemize}/\startitemize/g'
