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
\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...
