partial derivatives with bonum/pagella font
Hi all, The following examples give wrong space. There is a space between the prime and the subscripted x. If I do not load the bonum font it just looks as it should. \setupbodyfont[bonum] \starttext $f'_x$, $f_x'$ $f\prime_x$. \stoptext (it does not look good with the pagella font either...) Any ideas? /Mikael

cambria is the benchmark ... indeed bonum looks somewhat weird (also because the f is rather tightly bounded; the same with pagella) (there are some primes-*.tex test files in the test suite) the primes mechanism is somewhat non-trivial as ' is not really the prime symbol and some additional parsing / hackery happens; also, traditionally primes in tex sit on the baseline and need to be lifted one problem is that texgyre math is still beta so messing around at the tex end will interfere with improvements Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
OK!
is there a quick fix/hack that somehow allows me to get it look "almost
like it should" in a small document today with bonum? I'll give a
presentation tomorrow, and if this is not the case I'll change the notation
of partial derivative to the one using \partial instead...

one problem is that texgyre math is still beta so messing around at the tex end will interfere with improvements

Hi Mikael,

This might get you somewhere. I hope you don't have too many double primes in your document... NB: `%macros=mkvi` has to be the first line in the file. Cheers, Sietse % macros=mkvi \setupbodyfont[bonum] % This macro takes 1 arguments, #upper. It postfixes a negative kern just a % bit larger than the width of #upper, so that #upper does not push % the next content away to the right. \def\myprime#upper% {% 1. Store the width of the primes in a box, so we can get its width \setbox\scratchbox=\hbox{$#upper$}% % 2. We'll want to kern back by a bit more than \scratchdimen=\dimexpr \wd\scratchbox + 0.3em \relax% % The actual typesetting \kern 0em #upper\kern -\scratchdimen} \starttext % Quick and dirty 1: just pretend the prime is uppercased $f'_x$, $f_x'$ $f^{\prime\prime}_x$. % Less quick, still dirty: the \myprime macro defined above $f'_x$, $f_x'$ $f\myprime{\prime\prime}_x$. % Slow and dirty: add a kern between the \primes, % because bonum pushes them apart a bit. $f'_x$, $f_x'$ $f\myprime{\prime\kern -0.1em \prime}_x$. \stoptext
Thank you very much Sietse! This fits my needs for the students for
tomorrow...
I also defined
\def\sprime{\myprime{\prime}}
\def\dprime{\myprime{\prime\kern-0.1em\prime}}
Then $f\sprime_x$ and $f\dprime_{xx}$ is not too hard to write :)
