Wrong results for chemical structures and reactions
Hi, chemical structures and reactions produce wrong results. Here is one example from the wiki and two from the manual. \starttext %% does not typeset the reaction, prints the commas, wrong spacing %% and no arrow \startformula \chemical{2H_2,+,O_2,->,2H_2O} \stopformula %% same here, GIVES is not interpreted \startformula \chemical{A,GIVES,B,EQUILIBRIUM,C,MESOMERIC,D} \stopformula %% wrong alignment, rules overlay symbols \startformula \setupchemical [width=fit, height=fit, scale=small, size=small] \startchemical \chemical[ONE,Z0,DB1,SB46,MOV1,Z0,SB28][C,C] \stopchemical \startchemical \chemical[SPACE,PLUS,SPACE] \stopchemical \startchemical \chemical[ONE,Z0,SB146,Z6][N,H] \stopchemical \startchemical \chemical[SPACE,GIVES,SPACE] \stopchemical \startchemical \chemical[ONE,Z07,SB1357,MOV1,Z0,SB27,PB:Z2,ONE,Z0,SB13,PE][C,H,C,N] \stopchemical \stopformula \stoptext Am I missing something? Is this mechanism not supported any more or just broken? Marco

Hi,
chemical structures and reactions produce wrong results. Here is one example from the wiki and two from the manual.
\starttext
%% does not typeset the reaction, prints the commas, wrong spacing %% and no arrow \startformula \chemical{2H_2,+,O_2,->,2H_2O} \stopformula
%% same here, GIVES is not interpreted \startformula \chemical{A,GIVES,B,EQUILIBRIUM,C,MESOMERIC,D} \stopformula
%% wrong alignment, rules overlay symbols \startformula \setupchemical [width=fit, height=fit, scale=small, size=small] \startchemical \chemical[ONE,Z0,DB1,SB46,MOV1,Z0,SB28][C,C] \stopchemical \startchemical \chemical[SPACE,PLUS,SPACE] \stopchemical \startchemical \chemical[ONE,Z0,SB146,Z6][N,H] \stopchemical \startchemical \chemical[SPACE,GIVES,SPACE] \stopchemical \startchemical \chemical[ONE,Z07,SB1357,MOV1,Z0,SB27,PB:Z2,ONE,Z0,SB13,PE][C,H,C,N] \stopchemical \stopformula
\stoptext
Am I missing something? Is this mechanism not supported any more or just broken?

\startchemicalformula not \startformula \startchemicalformula \chemical{2H_2} \chemical{PLUS} \chemical{O_2} \chemical{GIVES} \chemical{2H_2O} \stopchemicalformula Also, the shorthand "+" for "PLUS", "->" for "GIVES", etc. seems to be interpreted only inline, not in displayed chemical formula mode. I am working (with Hans) to correct the mkiv chemical code, which has been completely re-written (from ppchTeX macros). Also working on a new manual, at the same time... Alan

\startchemicalformula not \startformula
\startchemicalformula \chemical{2H_2} \chemical{PLUS} \chemical{O_2} \chemical{GIVES} \chemical{2H_2O} \stopchemicalformula
The spacing is still wrong. Compare: \starttext \chemical{2H_2,+,O_2,->,2H_2O}\blank \startchemicalformula \chemical{2H_2} \chemical{PLUS} \chemical{O_2} \chemical{GIVES} \chemical{2H_2O} \stopchemicalformula \stoptext How to mid-align the reaction? Wrapping the \startchemicalformula in \startformula works, but it's clumsy.
Also, the shorthand "+" for "PLUS", "->" for "GIVES", etc. seems to be interpreted only inline, not in displayed chemical formula mode.

That's brilliant! Marco
