abbreviations as macros

abbreviations as macros

[ivo welch]

Hi Hans:

This is asking Armin Varmaz' question in a different way, although I
know even less.  I would like to define a macro that is just an
abbreviation.

For example, say I want to define a snippet \NPV which provides the
text NPV$_0$, and NPV is in textfont while 0 is in mathfont.  This
should work everywhere---formulas, subscripts, footnotes, etc., and
automatically appear in the correct sizing.

In LaTeX, this is easy to do:

  \newcommand{\NPV}{\text{NPV\ensuremath{_0}}}

I can now use \NPV\ in formulas, footnotes, subscripts, titles, etc.,
and it is properly sized everywhere.

Is there a recommended way to do this on conTeXt?

regards,

/iaw

If you never need to use a full form of the abbreviation, then you can 
just use the same in ConTeXt. The equivalent of \ensuremath is \math; 
everything else is the same.

\define\NPV{\text{NPV\math{_0}}

I would, however, write this slightly differently (even in LaTeX) as

\math{\text{NPV}_0}

but that is just a stylistic issue.

The usual way of defining abbreviations in ConTeXt is

\abbreviation [NPV] {\math{\text{NPV}_0}} {full form}

Then you can use

\NPV\ for a short form of the abbreviation and \infull{NPV} for the full 
form. The advantage is that you can also get a list of used abbreviations.
