There is a (new) problem typesetting text in chemical structures.
Alan
Minimal example:
\starttext
\startchemical
\chemical [ONE,Z0] [O]
\stopchemical
\stoptext
! terminal:
(/usr/local/context/beta/tex/texmf-context/metapost/context/base/mp-chem.mpiv)
>> labtype-10
! Unknown relation will be considered false.
<to be read again>
)
chem_text->...XPR3));p:=p.if(labtype(SUFFIX2)>=10)
:shifted(0,ypart.center.p)...
chem_z_zero->...(SUFFIX2)((TEXT3),chem_do(origin))
;endgroup
<*> chem_z_zero("\dochemicaltext{O}")
;
.
system > tex > error on line 4 in file foo.tex: terminal:
(/usr/local/context/beta/tex/texmf-context/metapost/context/base/mp-chem.mpiv)
>> labtype-10
! Unknown relation will be considered false.
<to be read again>
)
chem_text->...XPR3));p:=p.if(labtype(SUFFIX2)>=10)
:shifted(0,ypart.center.p)...
chem_z_zero->...(SUFFIX2)((TEXT3),chem_do(origin))
;endgroup
<*> chem_z_zero("\dochemicaltext{O}")
;
...
1 \starttext
2 \startchemical
3 \chemical [ONE,Z0] [O]
4 >> \stopchemical
5 \stoptext
6
\stopchemical ...erence \ctxlua {chemicals.stop()}
\egroup \chemicalwidth \wd...
l.4 \stopchemical
