Dear Alan, thanks a lot for fixed code. Could you point out where to find the updated manual for MkIV? Cheers, Henri On 07/07/2016 08:26 PM, Alan BRASLAU wrote:

Dear list,

I just wanted to check whether chemical structures typeset in ConTeXt can be exported as XML. Therefore I wanted to setup a simple example with ppchTeX. I copied example 3.1 from the manual [1]

...

\usemodule[chemic] \starttext

\startchemical[height=4500,bottom=2500] \bottext{$\beta$-D-Fructopyranose} \chemical[SIX,FRONT,BB1236,+SB4,-SB5,Z5][O] \chemical[SIX,FRONT,+R12346,+RZ12346][\SR{HO},H,H,H,OH] \chemical[SIX,FRONT,-R12346,-RZ12346][H,OH,\SR{HO},H,CH_2OH] \stopchemical

\stoptext

Unfortunately, typesetting with MkIV distributed with TL 2016 produces something really weird (see attached).

Is the module `chemic` compatible with MkIV or am I doing something wrong?

Cheers, Henri

\usemodule[chemic] is MKII. It has been replace with core MKIV commands.

The syntax has been somewhat rationalized and many bugs corrected.

The example can be reproduced as follows:

\starttext

\startchemical [height=4500,bottom=2500] \bottext{$\beta$-D-Fructopyranose} \chemical[SIXFRONT,BB123,B4,+SB5,-SB6,Z6] [O] \chemical[+LR12345,LRZ12345] [OH,\SR{HO},H,H,H] \chemical[+RR12345,RRZ12345] [CH_2OH,H,\SL{OH},\SR{HO},H] \stopchemical

\stoptext

Unfortunately, the revised manual still has some errors that I need to fix...

Alan
