Hi Hans,
can you add a \vspace command which behaves like \hspace but for vertical mode,
there are some cases where \blank is not so well suited (i know the \??vs
namespace
is already used by \blank)
\def\definevspace
{\dotripleempty\dodefinevspace}
\def\dodefinevspace[#1][#2][#3]%
{\ifthirdargument
\setvalue{\??vs#1:#2}{#3}%
\else
\setvalue{\??vs:#1}{#2}%
\fi}
\unexpanded\def\vspace
{\dodoubleempty\dohspace}
hm, untested ... ^^^^^^^^^
\def\dovspace[#1][#2]%
{\ifsecondargument
\dodovspace[#1][#2]%
\else\iffirstargument
\vspace[][#1]%
\else
\vspace[][\s!default]%
\fi\fi}
\def\dodovspace[#1][#2]%
{\vskip\vspaceamount{#1}{#2}}
\def\vspaceamount#1#2%
{\executeifdefined{\??vs#1:#2}{\executeifdefined{\??vs:#2}\zeropoint}}
i'm always a bit relucate to let users mess with vertical spacing ...
anyhow, in \hspace we clean up preceding space so vspace should behave
the same i.e. there should be a \removelastskip before the vskip
\def\dodovspace[#1][#2]%
{\par
\ifvmode
\removelastskip
\vskip\vspaceamount{#1}{#2}\relax
\fi}
i'll add it but we should not encourage too much in using it, that is,
i'm *not* going to look into spacing related bug reports that use this
command
Hans
