I, too, do not understand the
\definetextbackground
\starttextbackground
\stoptextbackground
commands, even though I tried looking at "details.pdf" (and core-
pgr.tex).
My particular problem is rather classic, that of illustrating
examples, set off from the main text.
I first used
\defineframedtext [example]
[width=fit,background=screen,backgroundscreen=0.7]
\startexample
...
\stopexample
and this is appropriate if the example is short enough to fit on one
page.
However, a long example (many paragraphs) that spans more than one
page
runs off the bottom.
Textbackground seems more appropriate, so I tried
\definetextbackground [example]
[location=paragraph,backgroundcolor=middlegray,frame=off]
\definestartstop [example]
[before={\starttextbackground[example]},after=\stoptextbackground]
but this does not work. I tried other variants (such as adding
state=start, ...) with no success.
Does anyone have suggestions on where to look for further
documentation or examples of use?
This works for me.
\setupcolors[state=start]
\definetextbackground
[example]
[location=paragraph,
background=color,
backgroundcolor=middlegray,
frame=off]
\starttext
\input knuth
\startexample
\dorecurse{4}{\input knuth\par}
\stopexample
\input knuth
\stoptext
