How to typeset a line as if it had zero height

How to typeset a line as if it had zero height

Dear all,

I have this simple MWE :

\starttext
\startsection[title=Section]
\startalignment[flushright]Line.\stopalignment  %% how to make this « 0 height » ? 
\input knuth
\stopsection
\stoptext

How can I, with ConTeXt or plain TeX, modify this simple example to typeset the text above as if the right aligned line (‘Line’ just below the section) had 0 height (ie the main paragraph with knuth quot is just after the section without blank line) ? By « 0 height » I mean it takes no vertical space but it is still typeset.

I hope my question makes sense.
Thanks a lot for any insiight.

Best regards

Joseph Canedo

Joseph,

I have come up with this very plain TeXy solution.

Cheers, Henri

\starttext

\startsection[title=Section]

\dontleavehmode% manually start a paragraph (smash does not)
\smash{% remove height
  \rlap{% remove width
    \raise \baselineskip \hbox to \textwidth{% shift one line back
      \rightaligned{Line}% typset right aligned
    }%
  }%
}%
\input knuth

\stopsection

\stoptext

You can use \offset to shift the text to a different position.

\define[1]\MoveText
   
{\dontleavehmode\offset[width=0pt,height=0pt,y=-\lineheight]{\rightaligned{#1}}\GotoPar}

\starttext

\startsection[title=Section]

\MoveText{Line}

\input knuth

\stopsection

\stoptext

The \GotoPar removes the following \par or empty line to ensure the 
previous and the following text stay on the same line.

%%%% begin example
\define\RuleOne{\dontleavehmode\blackrule[width=4cm,color=orange]}
\define\RuleTwo{\dontleavehmode\blackrule[width=4cm,color=yellow]\GotoPar}

\starttext

\RuleOne

\input ward

\RuleTwo

\input ward

\stoptext
%%%% end example
