单个段落 (ConTeXt) 没有网格？

Question

是否有可能grid=yes只在文本中对单个段落进行停用？应该是这样的\nogrid{ paragraph.... }。有\placeongrid{}- 但这不允许分页，因此如果需要分页，整个段落将在新页面上设置为一个段落。我认为这里不需要 minexample，任何段落都可以。

您只需将内容放入其中，\vbox然后\vsplit将其拆分成多页即可。为了不弄乱网格，请\snaptogrid在放置框时使用。

\showgrid
\setuplayout[grid=yes]

\unexpanded\def\startnogrid{%
  \setbox\scratchboxone=\vbox\bgroup}

\unexpanded\def\stopnogrid{%
  \egroup
  \scratchdimen=\dimexpr\pagegoal-\pagetotal-\topskip\relax
  %                                          ^^^^^^^^
  % This should not be \topskip but something else, but I don't know what.
  \ifdim\dimexpr\ht\scratchboxone+\dp\scratchboxone\relax>\scratchdimen
    \setbox\scratchboxtwo=\vsplit\scratchboxone to \scratchdimen
    \snaptogrid\hpack{\box\scratchboxtwo}
    \snaptogrid\hpack{\box\scratchboxone}
  \else
    \snaptogrid\hpack{\box\scratchboxone}
  \fi}
