well i do need the description as the items are not numbered or annotated in a 
sequential way.

i could use a \sym{tag} but then the available space is constant, and not 
variable as is when using description.

Or is there a better (simpler) way?

Re: [NTG-context] description renders unintended results (LUATEX BUG?)

[Alan Braslau]

You can see from your log that
context --pdftext
is running the MKII macros and
context
is running MKIV macros. The two systems are very different, MKII being
"frozen" and MKIV having evolved in some ways significantly. It is not
a question of TeX engines, but rather of entire systems.

But it sounds like you want to be using an itemize or enumeration
rather than a description.

Re: [NTG-context] description renders unintended results (LUATEX BUG?)

[Floris van Manen]

The incorrect nesting seems to be connected to the luatex engine.
If i have the same source compiled by pdftex, it works as intended.

So is the different rendering an intended feature of luatex, or a simple bug?

I got the left/right discrepancy between the sample code and the rendering.
However the unexpected is the fact that it does not indent properly:

The intended is this:

1   one
a   two
b   three
2   four
c   five
d   six
x   seven
y   eight
z   nine
3   ten

The unintended result (also in your rendering) is this:

1   one
a   two
b   three
2   four
c   five
d   six
x   seven
y   eight
z   nine
3   ten

While the alignment was to be expected, the items are still not nested.

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.

Re: [NTG-context] description questions

[Aditya Mahajan]

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.


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


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


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


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

Are these values accessible anyhow? Via Lua?


They are stored in \parindent but descriptions have the setting 
“indenting=never” which set parindent to 0pt. \setupindenting uses internal 
register to store the value before to assigns it to parindent but it’s not 
meant to be used by a user.

Re: [NTG-context] \description - indenting lines, alternative=top

[Procházka Lukáš Ing . - Pontex s . r . o .]

Hello Wolfgang,

thanks for the solution.

Two more questions:

- How to specify indenting to be equal to the normal paragraph indenting?

Here's my trial:


\setupindenting[yes,first,medium]

\define[1]\TestHeadCommand{\offset[x=-\parindent]{#1}} % This doesn't work

\starttext
  \definedescription
[test]
[alternative=top,
 margin=\parindent,
 headcommand=\TestHeadCommand,
]

  \input knuth

  \starttest{Knuth}
\input knuth
  \stoptest

  \input knuth
\stoptext


- Is it possible to reduce (or specify) the distance between the label and the 
next text?

XXX _
^
V - this distance to be specified.
  blablabla blabla
  blabla blabla bl
  a bla.


Best regards,

Lukas

 Hello Wolfgang,
 
 thanks for the solution.
 
 Two more questions:
 
 - How to specify indenting to be equal to the normal paragraph indenting?
 
 Here's my trial:
 
 
 \setupindenting[yes,first,medium]
 
 \define[1]\TestHeadCommand{\offset[x=-\parindent]{#1}} % This doesn't work
 
 \starttext
  \definedescription
[test]
[alternative=top,
 margin=\parindent,
 headcommand=\TestHeadCommand,
]
 
  \input knuth
 
  \starttest{Knuth}
\input knuth
  \stoptest
 
  \input knuth
 \stoptext
 


When you want a certain value in various places I would use \definemeasure to 
set it and \measure to access it.

\definemeasure[parindent][1em]

\define[1]\TestHeadCommand
  {\offset[x=-\measure{parindent}]{#1}}

\definedescription
  [test]
  [alternative=top,
   margin=\measure{parindent},
   headcommand=\TestHeadCommand]

\setupindenting[yes,\measure{parindent}]

\starttext

\input knuth

\starttest{Knuth}
\input knuth
\stoptest

\input knuth

\stoptext

Great, I didn't know about the \measure way.

Still - when I don't want to specify the indenting value directly, as I am 
satisfied with the value which is set by \setupindenting[medium] - is there a 
way how to get the indenting value in this case?

I mean - what value of indenting is set by \setupindenting[small], 
\setupindenting[medium], \setupindenting[big]?

Are these values accessible anyhow? Via Lua?

Best regards,

Lukas

They are stored in \parindent but descriptions have the setting 
“indenting=never” which set parindent to 0pt. \setupindenting uses internal 
register to store the value before to assigns it to parindent but it’s not 
meant to be used by a user.

You can indent the text with the margin parameter, the indenting of the head 
can be corrected with the \offset command.

\define[1]\TestHeadCommand
  {\offset[x=-1em]{#1}}

\definedescription
  [test]
  [alternative=top,
   margin=1em,
  %headcommand={\offset[x=-1em]},

 My trials e.g.:
 
 
 \definedescription[A][headstyle=bold,location=hanging,width=fit,]
 \definedescription[B][headstyle=bold,location=hanging,width=fit,margin=1cm,]
 \definedescription[C][headstyle=bold,location=hanging,width=fit,margin=1cm,command=\hskip-1cm]

\definedescription[B][headstyle=bold,alternative=hanging,width=fit,margin=2cm]
\definedescription[C][headstyle=bold,alternative=hanging,width=fit,margin=3cm]

When you don’t want any indentation you need “alternative=serried” because when
you set “margin=0pt” (for hanging) context don’t use this value but 1.5em 
instead.

... Thank you, now it's perfect.

So option alternative= is to be used instead of location=.

Does location still have any meaning or is it deprecated and replaced by 
alternative?

- On wiki, location is still frequently noticed...

Is this something like: red-right-returning?

Re: [NTG-context] description fails on \if

 Wolfgang,

  From your observation I am inclined to guess that the \ifx falls prey
 to the collection of arguments. The \relax can be replaced by an extra
 pair {} behind the description: \answerblock{}{}% also typesets
 without the if-error.

You could also add title=no to \definedescription[answerblock], this stops
TeX from looking after a optional argument between the braces.

 I more or less conclude that the lookahead from \dodoublegroupempty
 does not stop on the \if. If I remember correctly, that behaviour is
 to be expected from tex and the prospects for solving it generically
 within the format bleak. If Hans Hagen is listening, can he comment on
 this?

I tried your module also with my ancient ConTeXt from august last year
and it did also show this effect. Your module is broken since a very long time.

Re: [NTG-context] description fails on \if

 There is the following problem on code that did work around july 2007,
 but no longer under the current context version (2008-03-11).

 Define a description, I did:
 \definedescription[answerblock][%
\c!margin=\v!no,\c!location=\v!left,%
\c!headstyle=\@@exmintrostyle,\c!style=\@@exmstyle,%
\c!before=,\c!inbetween=,\c!after=,%
\c!hang=\@@exmhang,\c!width=\questionblockwidth,%
\c!text=\placeanswerstart]

Could you try to set title=no.

 Typeset with this description inside the following macro:
 \def\shortanswer#1\par{%
\par % be sure to end paragraph here
\answerblock{}% % {} needed here in description call
\ifanswers #1\else\dotfill\strut\fi %  crashing on this if
\par%  final \par of description ... \par
}
 The above code crashes with: ! Incomplete \ifx; all text was ignored
 after ...

 After some detective work in which Wolfgang Schuster had a large share
 and has found the most elegant workaround, the addition of a \relax
 just after the description call prevents the error:
 \def\shortanswer#1\par{%
\par % be sure to end paragraph here
\answerblock{}% % {} needed here in description call
\relax  %\relax prevents crash on if
\ifanswers #1\else\dotfill\strut\fi
\par%  final \par of description ... \par
}

 The way \relax stops the error reminds me of the \relax that one
 places after a number in order to separate that from the code following.
 I did compare core-des.tex, both the last version and the archived
 from 2007-04-17. But I must admit, I did not succeed finding a clue
 among the differences about what could have happened. The code is a
 bit too intricate to just jump in and pinpoint the culprit -- at least
 for me.

 Allthough Wolfgang's workaround saves the day, I feel this problem
 deserves solving inside ConTeXt, not outside it. Someday somewhere
 another person will stumble on the same problem -- a situation that
 can and should be avoided, in my view.
 Therefore I explain the problem here as fully as possible hoping
 someone knowledgeable with descriptions we might need to fall back
 to Taco or Hans will find the best remedy.

I would say the message comes from \dodoublegroupempty in \@@description.

i cannot put a \relax in there because \answerblock looks ahead

the argument grabber handles some of the if's but only the primitives;

in your case ... don't use \ifanswers, just use modes ...

\enablemode[answers] ... \doirmnode{answers}

you can play with this patch

\setvalue{@@description\v!hanging}[#1]#2%

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

 \definedescription[descr][

 \setupwhitespace[medium]

 \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.

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.
