description questions

[Csikos Bela]

Dear context users:

I am experimenting with descriptions and I couldn't find in the documentation
the following:

1. What is the default value of width option? It seems that default width uses the
longest head + some distance for every head in a descriptions list. Neither
width=fit nor width=broad,distance=dimension results in the same.

2. In the same document how can I reset to the default options of a defined
description list? For example:

\definedescription[defa]

\defa{head} .... % deafult options are used

\setupdescription[defa][width=broad,distance=1cm] 
\defa{head} .... % above options are used

Now I would like to use again the default options, how can I?

I tried:
\setupdescription[defa][] 
\defa{head} .... 

But still the previously set options are used, they haven't been reset.

Thank you in advance,

bcsikos

Some information is given here: http://www.ntg.nl/maps/36/09.pdf
Enumerations and descriptions share a lot of settings.

There is no way to reset options in ConTeXt. The canonical way to do this 
is:

\definedescription[defa]
\definedescription[defb][defa][width=broad, distance=1cm]

\startdefa ... \stopdefa

\startdefb ... \stopdefb

(Untested): This should also work:

\startdefa[width=broad, distance=1cm] ... \stopdefa

Sorry, I wasn't right. context uses a default width for head. Accidentally the longest
term I used in my document was almost the same as the default head width, therefore
I thought that the head was calculated according to my term's width.

Thank you. I read it. I have a question: is it possible to add some text or command
between the head and text in description? For example a dash or symbol which separates the head from the text. In enumerations it seems to be different, because
there the variable head (title) goes after a static head. I would need the opposite:
variable head part - static head part. I tried to use headcommand option but it puts
stuff before head.

I see. 

Thank you again,
