Hello there.
Currently \writebetweenlist doesn't work as advised. It inserts the
argument before the last entry of the list. The minimal example is
provided by the reference itself.
http://wiki.contextgarden.net/Reference/en/writebetweenlist
The rule is correctly inserted at http://live.contextgarden.net/ and in
the ConTeXt shipped with TeXlive 2010 (2010.05.24), but not with the
current beta and the 2010.07.30 version. mkii works fine.
It prints
--rule--
List entry A
List entry B
Best regards
--
Marco

Unfortunately, I can confirm this with current version:
ver: 2010.12.12 17:06 MKIV
Help please!

There is a good reason for this. Inbetween has multiple usage and these
are conflicting:
- in order to get the right page info associated it needs to be anchored
in the text stream
- in that case a node can interfere with spacing and can come unexpected
- sometimes direct flushing is needed, sometimes delayed
btw, all these issues have been observed by users every now and then
Now, if unexpected interference is the hardest to track down, inbetween
is an immediate action. In principle one can influence that but it's not
that intuitive. So, I've now added an option to (1) the flushers and (2)
the list placers.
The following example shows this:
\definelist[testlist][criterium=all]
\starttext
Regular list entries are bound to a specific location in order to
get the right pagenumber etc.\ associated. When pushing something
inbetween (in mkiv) it ends up directtly in the list. This is the
default because otherwise users will wonder why spacing might get
messed up (due to an unseen but present node). It is possible to
force a location by explicitly setting \type {location} to \type
{here}.
Another way to force a certain order is to set the \type {order}
variable when placing a list. The \type {command} option only
pushes commands into the right order, and \type {all} orders all
entries (which might be too much). In this case no specific
location is needed with the inbetween method. Maybe additional
mechanisms show up some day.
\subject{normal} \placelist[testlist]
\subject{command} \placelist[testlist][order=command]
\subject{all} \placelist[testlist][order=all]
\page \input tufte
\writetolist [testlist] {1} {One}
\writebetweenlist[testlist]
{\blackrule[color=red,width=\hsize]}
\writebetweenlist[testlist][location=here]{\blackrule[color=blue,width=\hsize]}
\writetolist [testlist] {2} {Second}
\writetolist [testlist][location=none]{W} {Whatever}
\writebetweenlist[testlist]
{\blackrule[color=green,width=\hsize]}
\stoptext
I admit that it's not an easy mechanism but any default would at some
point trigger complaints. So it probably needs to be wikified.

Thanks for this. It's been wikified in the reference wiki:

Thank you Hans for that extension
and thank you Marco for prompt wikifying!
