problem with \appendtoks \to\everypar

problem with \appendtoks \to\everypar

[Steffen Wolfrum]

Hi,


There is no hangover for italics. Please have a look:



\starttext
\def\hangover{\hangafter=1\hangindent=1em}

\definestartstop[hangingarea]
     [before={\bgroup\appendtoks\hangover\to\everypar},
      after=\egroup]

\starthangingarea
\input tufte

{\it italic} text roman test text roman test text roman test text  
roman test text roman test text roman test text roman test text roman  
test text roman test text
\stophangingarea

\stoptext



Thanks,

Steffen

This is a typical TeX gotcha. Don't start a paragraph with a group,
because the \everypar will be executed within the group. The problem
is not the italics but the { .

Do this:

\leavevmode
{\it italic} text roman test text roman test text  roman test text

> roman test text roman test text roman test text roman test text roman  
> test text roman test text
> \stophangingarea

Best wishes,

that's because the everypar happens in a group then (one of the nasty 
thinsg that is hard to take care of)

\dontleavehmode {\it ...

or put a strut in front
