IIRC, the original definitions are from plain.tex and amstex.tex.
plain.tex says:
\def\joinrel{\mathrel{\mkern-3mu}}
So I guess that \joinrel indeed needs to be defined on per-font basis
instead of being hardcoded into definitions.
the macro \loadfontgoodies in font-gds.mkiv should be extended
to something like
\def\loadfontgoodies[#1]%
{\ctxlua{fonts.goodies.get("#1")}%
\InputIfExists #1.tex%
}
which already load a lucida-math.ldf (lua code)
and then an optional lucida-math.tex (tex code)
don't know how ConTeXt can handle the \InputIfExists
The file lucida-math.tex in /context/fonts/
gets all font specific redefinitions, in this case
\def\joinrel{\mkern-4mu}
\def\longrightarrow{\relbar\joinrel\rightarrow}
\def\longleftarrow{\leftarrow\joinrel\relbar}
....
sich files are then possible for all other fonts
In lucida-math.lfg there is now:
variables = {
joinrelfactor = 4, -- default is 3
}
and when set that variable will be used in composing the virtual glyph
(the default is 3). So, no complex defs are needed. Maybe there are
more relevant variables.
