ConTeXt equivalent for \ensuremath?

ConTeXt equivalent for \ensuremath?

[Gerben Wierda]

I modeled this after the LaTeX sources because I had to move on:

\newcommand{\ensuremath}[1]{\ifmmode\expandafter\FirtsOfOne%
         \else\expandafter\EnsuredMath\fi}
\long\def\FirstOfOne#1{#1}
\long\def\EnsuredMath#1{$\relax#1$}

but is there a ConTeXt way of doing this?

Replacing \ensuremath above with \mathematics gives an error (both 
attempts):

>> \newcommand{\bit}[2]{\mathematics{{\hbox{\tf #1}_\hbox{\tf #2}}}}

But my way also doesn't work. I get empty output as a result of the 
\bit{b}{off} command.

Help?

This is probably not satisfying, because you probably want to get new
mathematics commands working, but if this is to be used solely in text,
you could use (or expand to):
 b\low{off}

\low (and \hi and \lohi) look like they work robustly in both math and
text modes.

I'm a bit confused by you using \newcommand in your (ConTeXt?) examples,
though...

I'll see. I wonder if it will look the same. Especially in terms of 
font. Do I get the same font in both sides? Do I get the same kerning?

Yes, strange, isn't it? It just works. I copied one accidentally over 
and it worked. So I kept using it.

you now say something like

<text>_\hbox

and since _ kind of takes an argument, it gets an hbox only; you need

<text>_{\hbox{..}}

as in:

\def\bit#1#2{\mathematics{\hbox{\tf#1}_{\hbox{\tf#2}}}}

\bit{1}{2}
