Hi,

Something has changed in the past couple months that causes my stretched title code to fail with the message:

! You can't use `\end' in internal vertical mode. <recently read> \normalend

I've attatched a small example. Has anyone a suggestion how I can adapt my code accordingly?

in a coming release i will support a more transparent stretching mechanism (using a font handling) so that such hacks are no longer needed anyhow, the problem with your 'plug-in' is that it acts on a complex stream of tokens, run this: \def\CapStretchAmount {0.3em} \def\CapStretch {\let\stretchedspaceamount\CapStretchAmount \stretchednormalcase} \def\stretchedbox#1% {\framed [frame=off, offset=.5em, align=middle, width=broad] {\showargument{#1}% \sc\CapStretch{#1}}} \setuphead [subject][rawtextcommand=\stretchedbox] \starttext \subject{feeling stretched feeling stretched feeling stretched feeling stretched} \processfile{tufte} \subject{feeling stretched} \processfile{tufte} \stoptext you will see that #1 is more than text, and i'm even surprised that it worked in previous versions. What you actually need is a deep hook: \def\c!deeptextcommand {deeptextcommand} \def\c!deepnumbercommand{deepnumbercommand} \def\doplaceheadtext#1#2#3#4% {\beginheadplacement{#1}% \ifemptyhead % = needed \setbox0=\ifvertical\vbox\else\hbox\fi to \zeropoint {\headnumbercontentfalse \resetsystemmode\v!sectionnumber #2}% \makestrutofbox0 \else % = needed \setbox0=\ifvertical\vbox\else\hbox\fi % \vhbox {\headnumbercontentfalse \resetsystemmode\v!sectionnumber % less interfering \ifcase\headtimingmode\or#2\fi % outerside font determines distance \dosetfontattribute{\??ko#1}\c!style % but we don't want color to influence user commands % todo: get the if-else out of it \getvalue{\??ko#1\c!command} {} % no number {\dostartattributes{\??ko#1}\c!style\c!color\empty \dostartattributes{\??ko#1}\c!textstyle\c!textcolor\empty \dontconvertfont \ifdisplaysectionhead \setupinterlinespace \else \setupspacing \fi % \ifcase\headtimingmode#2\fi % can introduce cr \getvalue{\??ko#1\c!commandbefore}% \placeheadmargintexts{#1}% binnen #3? \ifdisplaysectionhead \getvalue{\??ko#1\c!textcommand}% struts can be nilled with \setnostrut {\setstrut \begstrut \ifcase\headtimingmode\hbox{#2}\fi \executeifdefined{\??ko#1\c!deeptextcommand}\firstofoneargument{#3} \endstrut}% \hbox prevents break \xdef\localheadheight {\the\strutht}% \xdef\localheaddepth {\the\strutdp}% \xdef\localheadlineheight{\the\lineheight}% % == \globallet\localheaddepth\strutdepth \else \ifcase\headtimingmode#2\fi \getvalue{\??ko#1\c!textcommand}% {\executeifdefined{\??ko#1\c!deeptextcommand}\firstofoneargument{#3}}% \fi \getvalue{\??ko#1\c!commandafter}% \ifdisplaysectionhead\endgraf\fi \dostopattributes \dostopattributes}}% \fi \endheadplacement{#1}{#4}} \def\doplaceheadnumbertext#1#2#3#4#5% maybe move modes outside box {\beginheadplacement{#1}% \ifemptyhead % = needed \setbox0=\ifvertical\vbox\else\hbox\fi to \zeropoint {\doiftextelse{#3} {\setsystemmode \v!sectionnumber\headnumbercontenttrue } {\resetsystemmode\v!sectionnumber\headnumbercontentfalse}% #2}% \makestrutofbox0 \else % = needed \setbox0=\ifvertical\vbox\else\hbox\fi % \vhbox {\doiftextelse{#3} {\setsystemmode \v!sectionnumber\headnumbercontenttrue } {\resetsystemmode\v!sectionnumber\headnumbercontentfalse}% % less interfering \ifcase\headtimingmode\or#2\fi % outerside font determines distance \dosetfontattribute{\??ko#1}\c!style % but we don't want color to influence user commands \getvalue{\??ko#1\c!command}% {\dostartattributes{\??ko#1}\c!style\c!color\empty \dostartattributes{\??ko#1}\c!numberstyle\c!numbercolor\empty % \getvalue{\??ko#1\c!commandbefore}% strange, why here? moved 21/11/2005 \placeheadmargintexts{#1}% binnen #3? \ifdisplaysectionhead % can be nilled with \setnostrut \getvalue{\??ko#1\c!numbercommand}% {\setstrut \begstrut \executeifdefined{\??ko#1\c!deepnumbercommand}\firstofoneargument{#3}% \endstrut}% \else \getvalue{\??ko#1\c!numbercommand}% {\executeifdefined{\??ko#1\c!deepnumbercommand}\firstofoneargument{#3}}% \fi \dostopattributes \dostopattributes} {\dostartattributes{\??ko#1}\c!style\c!color\empty \dostartattributes{\??ko#1}\c!textstyle\c!textcolor\empty \dontconvertfont \ifdisplaysectionhead \setupinterlinespace \else \setupspacing \fi % \ifcase\headtimingmode#2\fi % can introduce cr \getvalue{\??ko#1\c!commandbefore}% makes more sense here \placeheadmargintexts{#1}% binnen #3? \ifdisplaysectionhead \getvalue{\??ko#1\c!textcommand}% struts can be nilled with \setnostrut {\setstrut \begstrut \ifcase\headtimingmode\hbox{#2}\fi \executeifdefined{\??ko#1\c!deeptextcommand}\firstofoneargument{#4}% \endstrut}% \hbox prevents break \xdef\localheadheight {\the\strutht}% \xdef\localheaddepth {\the\strutdp}% \xdef\localheadlineheight{\the\lineheight}% % == \globallet\localheaddepth\strutdepth \else \ifcase\headtimingmode#2\fi % inside textcommand ? \getvalue{\??ko#1\c!textcommand}% {\executeifdefined{\??ko#1\c!deeptextcommand}\firstofoneargument{#4}}% \fi \getvalue{\??ko#1\c!commandafter}% \ifdisplaysectionhead\endgraf\fi \dostopattributes \dostopattributes}}% \fi \endheadplacement{#1}{#5}} \protect \def\CapStretchAmount {0.3em} \def\CapStretch {\let\stretchedspaceamount\CapStretchAmount \stretchednormalcase} \def\stretchedbox#1% {\framed [frame=off, offset=.5em, align=middle, width=broad] {%\showargument{#1}% \sc\CapStretch{#1}}} \setuphead [subject][deeptextcommand=\stretchedbox] \starttext \subject{feeling stretched feeling stretched feeling stretched feeling stretched} \processfile{tufte} \subject{feeling stretched} \processfile{tufte} \stoptext
