Hello,

I've been trying to come up with a few methods to add definitions to
text with the help of the metafun and context manuals. The first method
adds the definition as sort of a "superscript" on top of the word, and
the second one marks multiple words with a curly bracket and adds the
definition on top of the tip of the bracket.

Here is the (ugly and hackish) code:

\startuniqueMPgraphic{defline}
path p; p:=(0,0)..controls (0,1) and (1,1)..(1,1)--(6,1)..controls(7,1)
and (7,1)..(7,2)--(7,2)..controls(7,1) and
(7,1)..(8,1)--(13,1)..controls(13,1) and (14,1)..(14,0);
draw (0,0)--(0,12pt) withcolor white;
draw p xscaled (\overlaywidth/15) yscaled 5 shifted (0,9mm) withpen
pencircle scaled 0.25mm withcolor red;
\stopuniqueMPgraphic

\defineoverlay[curlybracket][\includeMPgraphic{defline}]

\def\sentencedef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to
\the\wd\scratchbox{\cbox{\hbox{\tfxx\color[red]
#1}\\\hbox{\framed[background=curlybracket,frame=off]{#2}}}}}

\def\worddef[#1][#2]{\setbox\scratchbox=\hbox{#2}\hbox to
\the\wd\scratchbox{\cbox{\hbox{\rotate[rotation=25]{\tfxx\color[red]
#1}}\\\hbox{#2}}}}

\starttext

\hbox{\worddef[def1][Lorem] ipsum \worddef[def2][dolor] sit

\hbox{\sentencedef[def5][Lorem ipsum] dolor sit \sentencedef[def6][amet

\stoptext

I haven't figured a way to add the curly bracket graphic neatly nor
position the definition correctly on top of it.

I would be very interested in any advice regarding these two functions
and how to rewrite both of them in a more elegant way.


Wikifyable ...

\startuniqueMPgraphic{defline}{width}

Another solution, which might be easier to understand. This does not affect the lineheight. Depending on the usage, that may or may not be desirable.

\unprotect
\startuniqueMPgraphic{defline}
path p ;
p :=
( 0,0) .. controls  (0,1) and ( 1,1) ..
( 1,1) --
( 6,1) .. controls  (7,1) and ( 7,1) ..
( 7,2) --
( 7,2) .. controls  (7,1) and ( 7,1) ..
( 8,1) --
(13,1) .. controls (13,1) and (14,1) ..
(14,0) ;
draw
p
xysized (OverlayWidth,ExHeight)
shifted (0,OverlayHeight)
withpen pencircle scaled .1ExHeight
withcolor \MPcolor{\framedparameter\c!framecolor} ;

label.top((textext("\tfxx\color[red] \framedparameter\c!text") rotated 25),
(OverlayWidth/2, OverlayHeight+ExHeight));

setbounds currentpicture to boundingbox OverlayBox ;

\stopuniqueMPgraphic

\defineoverlay[curlybracket][\includeMPgraphic{defline}]

\defineframed[LineDef]
[
\c!location=\v!low,
\c!frame=\v!off,
