Description nesting

Description nesting

[nico]

Hello,

Is there a way to nest some descriptions, where the nested descriptions  
respect the enclosing indentation?

Funnily the wiki speaks about the subject  
(http://wiki.contextgarden.net/Description) but doesn't give any solution  
(btw, the given solution to have several paragraphs in a description looks  
obsolete since \start \stop works pretty well).

Here is an example that I would like to see working:

\definedescription[descr][
   headstyle=bold,style=normal,align=left,location=hanging,
   width=broad,margin=1cm]

\setupwhitespace[medium]

\starttext

\startdescr{Para}
   This is a shorter item label, and some text that talks about it.
   The text is wrapped into a paragraph, with successive lines indented.

   This is another paragraph under the "Para" item.

   \startdescr{SubPara1}
   This is a shorter item label, and some text that talks about it.
   The text is wrapped into a paragraph, with successive lines indented.
   \stopdescr
   \startdescr{SubPara2}
   This is a shorter item label, and some text that talks about it.
   The text is wrapped into a paragraph, with successive lines indented.
   \stopdescr
\stopdescr

\stoptext

Try,

  \definedescription[descr][
     headstyle=bold,style=normal,align=left,location=hanging,
     width=broad,margin=2em, before=\doMySetup]

  \def\doMySetup{
     \setupdescriptions[descr]
     [before=\startnarrower,after=\stopnarrower]}

you can play with this patch

\setvalue{@@description\v!hanging}[#1]#2%
  {\@@dostartdescription[#1]{\def\\{\crlf}}{#2}% % adds \c!margin to 
\leftskip
   \noindent\ignorespaces
   \advance\leftskip -\leftskipadaption \relax
   \ifdim\leftskipadaption=\zeropoint
     \leftskipadaption1.5em % just some default
     \ifnum\insidedefinition=\plusone
       \ifdim\leftskip>\zeropoint \relax
         \leftskipadaption\leftskip
       \fi
     \fi
   \fi
   \ifnum\insidedefinition>\zerocount
     \advance\leftskip \leftskipadaption
   \fi
   \hskip-\leftskipadaption
   \ifhbox\@@descriptionbox\unhcopy\else\copy\fi\@@descriptionbox
   \kern\ifdim\!!widthb=\zeropoint .75em\else\!!widthb\fi
   \ignorespaces
   \@@dodescription}

Ok, it works fine, thanks! It also makes the indentation of a hanging  
description put in an itemize more consistent.

BTW, I wonder if it should not be also applied to location=left.

btw, we need some test files for descriptions in the test-suite

I've added two tests under core-des.tex/, one about basic combination of  
location and width options, the other about the footnotes.
