\glueexpr in lmtx

\glueexpr in lmtx

[Marcel Fabian Krüger]

Hi,

I stumbled upon some odd behaviour of \glueexpr in lmtx. Take the
following document:

\starttext
\the\glueexpr 0.0pt \relax
\newskip\myskip
\myskip=\glueexpr 0.0pt \relax
\stoptext

Without lmtx this works fine. Under lmtx, the *first* use of
`\glueexpr`, after `\the`, works fine too. On the other hand, the other
`\glueexpr`, after `\myskip=`, complains about a "Illegal unit of
measure (pt inserted)". It does not seem to accept the fractional part,
everything works again if I use

\starttext
\the\glueexpr 0.0pt \relax
\newskip\myskip
\myskip=\glueexpr 0pt \relax
\stoptext

Am I missing something here or is this a bug?


Best regards,

Marcel Krueger

fixed in next lmtx beta (was a wrong symbolic constant someplace)

(context never uses gluexpr so it went unnoticed)
