hi list,
new to `context' and my first question to the list: how can I achieve
the following (`latex') behaviour:
\newcommand{\km}{\ensuremath{K_m}}
We can now use \km\ in the body text as well as in this
\begin{equation}
\km = 1
\end{equation}
display equation.
in `context'? I've tried something like
\def\km{\math{K_m}}
We can now use \km\ in the body text but get sytnax errors when
putting it in this
\startformula
\km = 1
\stopformula
formula.
but this fails for obvious reasons (as would using `$$' instead of
`ensuremath' in the `latex' case).
so what I need is a way of defining (potentially complex)
math-expressions via some shortcuts/definitions/macros/abbreviations
(whatever) which I can then use
in the formula environment (or whatever it's called in `context'...) as
well as in the body text.
any help appreciated,
In ConTeXt you have to write
\define\km{\mathematics{K_m}}
but there is not much to gain from this because you can enter math mode
in the text with \m{…}.
thanks for the response. in my silly example you are right (but even there
it saves more than 50% of keystrokes). but I'm thinking of course of more
tedious math expressions where it rapidly is handy to use such
abbreviations -- the more so, if you have, say, 20 different ones
appearing repeatedly in the document. but that would work with the
`\def..\math' construct in the body text. what does _not_ work, then, is
to use the definition in a display (\startformula...\stopformula) equation
(which it _does_ in latex when isolating the math expression with
`ensuremath'). so my real question(s) are:
1. is there any way to achieve the same functionality in `context'
(expansion of math-containing defintion/macro/abbreviation in text _and_
math environment? if yes, how would I do this?
2. if no, would it be sensible (and feasible) to modify `\math' behaviour
and to make it aware of whether it is called from within text or from
within a display equation (in which case it should do nothing...), i.e.
mkae it behave like `\ensuremath' in latex?
thx/joerg
Wolfgang
