\everymath and ' accent

\everymath and ' accent

[morgan.brassel]

Hi everyone,

This topic has already been discussed on the list, but I didn't clearly
understand the conclusion, so I'm asking again... It is not clear to me why the
following

\everymath{\displaystyle}
\starttext
\startformula \frac{1}{A'} \stopformula
$\frac{1}{A'}$
\stoptext

fails with ConTeXt (on the ' inside $.$), while

\documentclass{minimal}
\everymath{\displaystyle}
\begin{document}
\[ \frac{1}{A'} \]
$\frac{1}{A'}$
\end{document}

is ok with LaTeX.

The use of \everymath is to blame here, but why?
Thanks in advance!
Morgan

it's pretty dangerous to overload \everymath

maybe \appendtoks\displaystyle\to\everymath works

Selon Hans Hagen <pragma@wxs.nl>:

Yes, I guess so! It was just to see the difference between LaTeX and ConTeXt in
this case.

Indeed, thank you! What I need actually is to modify $.$ locally (in a tikz
picture) to produce \displaystyle maths. I don't know what is the best way to
achieve this. Is it to use \appendtoks like above?

Best regards,
Morgan
