Hi
I am using context to run a metapost graph. I am however unable to
insert a label with \frac, since this is not pure Tex but Latex. This
seems to be a known problem for metapost:
-Seems for metapost only, one should add %&latex
(http://ryanmlayer.wordpress.com/tag/metapost/).
-I saw also one post where it was mentione done should add
//\setupMPpage[offset=1pt]
//(http://www.tug.org/pipermail/pdftex/2001-March/000429.html). I tried,
but did not work however...
Any idea how I should do? Find below minimal example, that does not work
on my computer when compiling with context...
Thanks!!
Matthieu
\starttext
\setupMPpage[offset=1pt]
\switchtobodyfont[10pt]
% Beginning MetaPost graphic
\startMPpage
label.top(btex 1.4 etex scaled 1.00, (10, 10));
label.top(btex $\sigma_t$ etex scaled 1.00, (0, 10));
label.top(btex $\displaystyle \frac{\sigma_t}{a}$ etex scaled 1.00,
(1, 1));

best use textext ...
label.top(textext("1.4") scaled 1.00,
(10, 10));
label.top(textext("$\sigma_t$") scaled 1.00, (0,
10));
label.top(textext("$\displaystyle \frac{\sigma_t}{a}$") scaled 1.00, (1,
1));
works ok (only tested mkiv); also \frac is available in context

Dear Hans
Thanks for your quick answer! I was however not able to produce the
graph with the textext code... Should I actually then use another
compiler? I tried with context and texexec (I thought texexec is the
compiler for mkiv, right? I'm on linux ubuntu).
I saw also that, as you mention, context has a \frac:
http://wiki.contextgarden.net/Math_with_newmat
I tried then to simply add \usemodule[newmat] and compile with context,
but did not work... Code below, error message below below...
Thanks a lot!!!!

no, use the 'context' command as texexec is for mkii

indeed, \frac is already there for a long time (ams compatible command)
btw, in mkiv there is no m-newmath

make sure that a font is loaded that has math before \starttext is seen
(try with \setupbodyfont[palatino] at the top of your file)

ok, so I was using the right compiler.... I get a mystake while trying
to compile a file with the code you sent... you didn't? Would you be so
nice and send complete file, so I can check what is wrong?

this does not work neither.... I still get error message with this code:
\usemodule[newmat]
\setupbodyfont[palatino]
\starttext
\startMPpage
label.top(textext("$ \frac{\sigma_t}{a}$") scaled 1.00, (1, 1));
%label.top(btex $ \frac{\sigma_t}{a}$ etex, (0, 10));
%label.top(textext( $\displaystyle \frac{\sigma_t}{a}$ ) scaled 1.00, (1, 1));
\stopMPpage
\stoptext
Thanks a lot for your help!!!!

Hi,
this works for me.
\setupbodyfont[palatino]
\startMPpage[offset=1ex]
u := cm ;
label.top(textext("$ \frac{\sigma_t}{a}$") scaled 2, origin);
label.top(textext("$ \frac{\sigma_t}{a}$"), (u,u));
label.top(textext("$\dfrac{\sigma_t}{a}$") scaled .5, (u,0));
\stopMPpage

Andreas

Thanks for answer!
Is this code you wrote supposed to be the whole doc to compile? And
compiled with context? If yes, I got an error again... I have version
context --version
MTXrun | main context file: /usr/share/texmf/tex/context/base/context.tex
MTXrun | current version: 2009.11.26 16:2
Is it likel;y then that the problem is solved in more recent versions? I
would try to update then... I am on Ubuntu 10.10 64b, is there a simple
way to update from other repos, or should I compile?
Thanks for your help!!!

that's rather old for a luatex/context combination
on the wiki you can find how to install minimals (takes a few minutes
only, no compilation needed)
