scratchdimen mess (alpha)

scratchdimen mess (alpha)

[Peter Rolf]

[-- Attachment #1: Type: text/plain, Size: 457 bytes --]

Hi all,

can someone test the attached example with the (latest) alpha version of 
ConTeXt?
Using mkiv I get no additional space in case of the \scratchdimen example.
I tried it with two new installations (minimals) from the scratch and 
also used several luatex versions, but the error remains. Strange...

Best wishes, Peter

\scratchdimen is a internal value and redefined in the \framed macro,
you get different results in MkII and MkIV because both use their own
definition of \framed.

The same "error" is in the month old context and luatex that I have.  I 
suspect that framed or the page builder is using \scratchdimen internally, 
and that is messing things up.

well, you can never rely on scratchdimen not being used inside the macro 
that you call (in this case it's used right at the start of \framed)

for mkiv i now use a local scratchdimen but you can not rely on that to 
happen fro all places where i use scratcdimen myself


\def\Space#1#2%
  {\expanded
     {\framed
        [width=\the\dimexpr#1\relax,
         height=\the\dimexpr#1\relax,
         frame=on,
         framecolor=green,
         rulethickness=.25pt,
         offset=overlay]}
        {}}

or so is another solution

no need to change things on your side. i already use private 
(scratchdimen) registers in nearly all of my macros, so i'll simply fix 
the remaining ones.
