Hi Hans,
The unit scanner in LuaMetaTeX fails for any of the "true" dimensions.
With this test file:
\starttext
\vrule width 1truein height 1pt depth 0pt\relax
\vrule width 1in height 1pt depth 0pt\relax
\stoptext
I get this output:
tex error > tex error on line 2 in file ./lmtx-true.tex: Valid keyword
expected, likely 'true'
<line 3.2>
\vrule width 1truei
n height 1pt depth 0pt\relax
1 \starttext
2 >> \vrule width 1truein height 1pt depth 0pt\relax
3
4 \vrule width 1in height 1pt depth 0pt\relax
5 \stoptext
6
I was able to fix this with the patch at the end of the email.
(Also, how do you want patches sent? Via email to the mailing list,
emailed directly to you, as a pull request on GitHub, or something
else?)
Thanks,
