[NTG-context] Fira Math: goodies needed?

[Leah Neukirchen]

Hi,

I'm trying to use Fira Math (https://github.com/firamath/firamath).

But this small example yields both limits on the same horizontal axis,
i.e. the 0 is far away from the integral sign:


\definefontfamily [mainface] [mm] [Fira Math]
\setupbodyfont    [mainface]

\starttext
\startformula
  \int_0^1 e^x
\stopformula
\stoptext


Meanwhile, when I use LaTeX, the 0 is moved to the left and close to
the integral sign:


\documentclass{article}
\usepackage{amsmath}
\usepackage[mathrm=sym]{unicode-math}
\setmathfont{Fira Math}

\begin{document}
\[
  \int_0^1 e^x
\]
\end{document}


In both cases
/opt/texlive/2023/texmf-dist/fonts/opentype/public/firamath/FiraMath-Regular.otf
is used...

As far as I remember, we did not consider firamath usable last time we
tested. Is it OK?

Attached you find a very basic goodie file that 1) set the
primeshiftup parameter and 2) enables presets.moveintegrals. Also add

\definefontfeature[default][default][goodies=fira-math.lfg]

to use it.

It's not exactly great, but I like the font itself for slides; I guess
it works for simple math.

Thanks, that works!
