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}

Thank you! I will wikify the examples with an explanation on the
syntax. However I would be interested in learning more about the bgrop,
dontleavehmode, raise etc. commands. The cont-eni manual uses them but
without explanation on their exact syntax and use cases.

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.
