Typearea module fails with “Missing number”

Typearea module fails with “Missing number”

[Marco Patzer via ntg-context]

Hi!

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

LMTX 2022.08.25 19:21

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outdated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

Unfortunately, I can not upload it to modules.contextgarden.net:
"Unknown user or bad password!"

Taco, what should I do please?

TIA,

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.
