Hi List,
I am converting problem sets from LaTeX to ConTeXt and ran into a puzzling
problem. I define \sub to produce subscript text in math mode. (See definition
below.) This worked for my ConTeXt book, but fails in the problem sets because
in ConTeXt \sub is a special item command, and I use itemize to number problems.
Obviously, I can rename my \sub command, but it is already used in hundreds of
problems and solutions that I am converting. Is there a way to get my \sub to
work in an itemize? I only need it in math mode. I will never use \sub for its
ConTeXt itemizing purpose.
\appendtoks
\define[1]\sub{_{\text{\rm\tf#1}}}%
\to \everymathematics
or nicer:
\define[1]\MyMathSub{_{\text{\rm\tf#1}}}
\appendtoks
\let\sub\MyMathSub
\to \everymathematics
Thanks!
Gavin
\define[1]\sub{_{\text{\rm\tf#1}}}
\starttext
$E\sub{final}$ is the final energy, but not in an itemize:
\startitemize
\item $E_{\text{\rm final}}$ is the final energy.
\item $E\sub{final}$ is a mess.
\stopitemize
\stoptext
