Hello,
in tex/texmath.c, the `math_param_names` array is missing the entries
`skewedfractionvgap` and `skewedfractionhgap`. This causes all array
indices to be shifted and therefore a mismatch between the parameter
names in Lua and the real names. For example:
\showthe\Umathlimitabovevgap\displaystyle
\showthe\Umathskewedfractionvgap\displaystyle
\directlua{
print('limitabovevgap:', tex.getmath('limitabovevgap', 'display'))
print('skewedfractionvgap:', tex.getmath('skewedfractionvgap', 'display'))
}
\bye
results in
> 1.11111pt.
l.1 \showthe\Umathlimitabovevgap\displaystyle
?
> 0.0pt.
l.2 \showthe\Umathskewedfractionvgap\displaystyle
?
limitabovevgap: 0
[\directlua]:1: bad argument #1 to 'getmath' (invalid option 'skewedfractionvga
p')
