Hans,
Since we have some leverage with backward compatibility in MkIV, can we
make \setuppapersize (slightly) more intuitive.
Normally, one would expect
\setuppapersize[A5]
to be equivalent to
\setuppapersize[A5][A5]
but currently it is equivalent to
\setuppapersize[A5][A4]
This is a bit confusing, and means that we always have to specify the
printpaper size; even if it is equal to paper size. Can we modify the
definition of \dodefinepapersize to change this behavior?
\def\dodefinepapersize[#1][#2][#3]%
{\ifsecondargument
\doifsomething{#1} % to be sure
{\doifassignmentelse{#2}
{\getparameters
[\??pp#1] % geen \c!scale, scheelt hash ruimte
[\c!width=\@@ppwidth,\c!height=\@@ppheight,\c!offset=\@@ppoffset,#2]%
%AM: Added these two lines
\setvalue{\??pp:1:#1}{#1}%
\setvalue{\??pp:2:#1}{#1}}%
{\setvalue{\??pp:1:#1}{#2}%
\setvalue{\??pp:2:#1}{#3}}}% (*) see below
\else
\getparameters[\??pp][#1]%
\setuppapersize % hm. this will freeze !
\fi}
Perhaps, in line (*), we should also check if #3 is something, otherwise
set ??p:2:#1 to #2:
\doifsomethingelse{#3}
{\setvalue\??pp:2:#1}{#3}}
{\setvalue\??pp:2:#1}{#2}}
What do you think?
more elegant and downward compatible is this:
\definepapersize
[samesized]
[ \c!width=\paperwidth,
\c!height=\paperheight]
\setuppapersize
[A4][samesized]
in page-lay.mkiv
