Overlapping terms in description lists

Overlapping terms in description lists

[Tom Harrop]

Hello again,

The document I'm typsetting uses description lists. To keep the list 
entries close together I'm using before=\nowhitespace and 
after=\nowhitespace in \definedescription. This is fine so long as the 
term is short, but when the term wraps to two lines it can overlap with 
the term below.

Here's an example:

> \setuppapersize[A5]
> \setupalign[flushleft, nothyphenated]
>
> \definedescription[description]
>     [before=\nowhitespace, after=\nowhitespace]
>
> \starttext

> \stopdescription
>
> \startdescription{This is a really long term:}
>   ... the long term of the item above the mashes into the term below.
> \stopdescription
>
> \stoptext

And here is an attempt at a plain text representation of what I'm trying 
to achieve:

Is this possible using \definedescription? I tried some combinations of 
\vfill and \framed but I couldn't get it to work.

Sorry to repeatedly post newbie questions. Any tips would be appreciated!

Thanks,

Tom

the title is in  a \vtop and not a \vbox, and its height is fixed to
\strutht (and the depth to \strutdp)
so basically the title is one line.

You can try with hand-tuning, ie

\definedescription[description][before=\nowhitespace,
after=\vskip0.25em,width=7\emwidth]
\starttext
\startdescription[title=This is a really long term:]
\crlf
  Long term + short definition
\stopdescription

\startdescription[title=This is a really long term:]
\crlf
  ... the long term of the item above the mashes into the term below.
\stopdescription
\stoptext

OK, I’ll do my best to stick to one line.

I guess it would be better to use a paragraphs or column environment for long labels but the ConTeXt is generated by pandoc, which writes 'definition lists' as \startdescription \stopdescription.
