Subject: calculating with dimension unit
Date: Mon, 22 Apr 2013 01:13:15 +0200 [thread overview]
Message-ID: <5174728B.70102@gmx.de> (raw)
In a book I produced with ConTeXt last year, I did a lot of
calculation to be able to change the layout dynamicaly.
With the actual version of ConTeXt I can't compile the book.
I have tried a lot of things today ... without success.
I hope my minimal-example helps you to understand, what I
want to do - and what I am doing wrong:
\starttext
\setupexternalfigures[location={local,global,default}]
\defineexpandable\ColumnA {30mm}
\defineexpandable\ColumnB {40mm}
\defineexpandable\ColumnABi {\dimexpr(\ColumnA + \ColumnB)}
\defineexpandable\ColumnABii {\ctxlua{context(\ColumnA +
\ColumnB)}}
\newdimen\ColumnABiii \ColumnABiii = \dimexpr(\ColumnA +
\ColumnB)
A \ColumnA% ok
B \ColumnB% ok
% I sadly get only errors when I delete the comments:
%ColumnABi: \ColumnABi
%ColumnABii: \ColumnABii
%ColumnABiii: \ColumnABiii
%\externalfigure[cow][width=\ColumnABiii]
~
\page
\stoptext
