Re: [NTG-context] Math prime issues for some fonts

Hi Jack, I've been working with Hans on math in general and primes in particular in the last week. I do not understand all the details, but I think primes are handled differently now, and that one essentially need to have some tuning in goodie files (the reason is that they are done differently in different fonts, and that there was not simple one-fits-all solution). We have not touched eulernova yet. In any case, if you replace euler-math.lfg and type-imp-euler.mkiv in ConTeXt-lmtx/tex/texmf-context/tex/context/fonts/mkiv/ with the attached files, I think at least the primes should look OK (you could experiment with the values in euler-math.lfg). The sample file \setupbodyfont[eulernova] \starttext \m{x'(t)f'(x)f''(x)e^{f'(x)}} \stoptext looks OK here. /Mikael On Fri, Nov 26, 2021 at 7:54 PM Jack Hill via ntg-context wrote:

Hi list,

When I run this test code

\definefontfamily[trm][math][tex gyre termes math] \definefontfamily[pag][math][tex gyre pagella math] \definefontfamily[bon][math][tex gyre bonum math] \definefontfamily[sch][math][tex gyre schola math] \definefontfamily[stx][math][stix two math] \starttext \starttabulate[|c|c|] \FL \NC \bf Font name \NC \bf Math prime \NR \ML \NC Latin modern \NC \m{x'} \NR \NC Termes \NC \switchtobodyfont[trm] \m{x'} \NR \NC Pagella \NC \switchtobodyfont[pag] \m{x'} \NR \NC Bonum \NC \switchtobodyfont[bon] \m{x'} \NR \NC Schola \NC \switchtobodyfont[sch] \m{x'} \NR \NC Stix \NC \switchtobodyfont[stx] \m{x'} \NR \BL \stoptabulate \stoptext

on my machine, the prime symbols are being placed too high (except for latin modern which is normal). Running the same code on the wiki gives the correct output though. Does anyone else get the same output? Screenshot attached.

Use \definetypeface to load/set the math fonts.

\starttext

\starttabulate[|l|c|] \FL \BC Font name \BC Math prime \NC\NR \ML \NC Latin Modern Roman \NC \m{x'} \NC\NR \NC TeX Gyre Termes \NC \switchtobodyfont[termes] \m{x'} \NC\NR \NC TeX Gyre Pagella \NC \switchtobodyfont[pagella] \m{x'} \NC\NR \NC TeX Gyre Bonum \NC \switchtobodyfont[bonum] \m{x'} \NC\NR \NC TeX Gyre Schola \NC \switchtobodyfont[schola] \m{x'} \NC\NR \NC STIX Two \NC \switchtobodyfont[stixtwo] \m{x'} \NC\NR \BL \stoptabulate

\stoptext

Thanks, \definetypeface fixes it. Should I not be using \definefontfamily? I've just checked eulernova and the prime is still too high for this font.
