The typearea module fails on LMTX (runs ok with MkIV):

tex error > tex error on line 89 in file /usr/local/share/context-lmtx/tex/texmf-modules/tex/context/third/typearea/t-typearea.tex: Missing number, treated as zero

Sorry, forgot the MWE:

\usemodule[typearea] \starttext\null\stoptext

To fix the module you have to change the line

\edef\Ratio{\withoutpt{\the\dimexpr2\paperheight/(\PageWidth/32768)\relax}}

with (remove one pair of curly braces)

\edef\Ratio{\withoutpt\the\dimexpr2\paperheight/(\PageWidth/32768)\relax}

Similar problems can happens with other modules because many of them are outdated and they should be either updated or removed (the files can still be archived).

Hi Wolfgang,

Thanks. Here a new version: http://pmrb.free.fr/tmp/t-typearea.zip

Even though the module works now with LMTX it needs a proper update to ensure it can be used in future documents.

Another suggestion from myself is to use the \averagecharwidth length for the calculation of the text width because it takes the document language into account.
