description renders unintended results

description renders unintended results

[Floris van Manen]

[-- Attachment #1.1.1: Type: text/plain, Size: 1523 bytes --]

The documentation on page
http://wiki.contextgarden.net/Description

provides sample code to stack multiple levels of description such as:

\setuppapersize[A5]
\definedescription[descr][

  headstyle=bold, style=normal, align=left, location=hanging,
  width=broad, margin=1cm
]
\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{Sub Item}

    This is a description of an item which is within the "Para" item.

\stopdescr
\startdescr{Sub Item}

    Another Sub Item

\stopdescr
\stopdescr
\startdescr{Short}

  A short item that's not part of that really long "Para" item.

\stopdescr
\stoptext

which should generate the included rendering.




But reality is somewhat more diverse …
My current context / luatex, as well as the online context engine come up with a different rendering



Even when you correct for the right/left alignment, the itemising does not properly stack up:



It there a work around ?


$ context --version

mtx-context     | ConTeXt Process Management 0.63
mtx-context     |
mtx-context     | main context file: /Applications/ConTeXt/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2016.09.24 12:40

$ luatex --version
This is LuaTeX, Version 1.0.0 (TeX Live 2017/dev)


Thanks

Hi Floris,

Since you specify
	align=left
in the setup of your description, I don’t see why the output would be unexpected. With the following version of your example code I get the attached PDF output.

%%% begin 
\setuppapersize[A5]
\definedescription[descr][
	headstyle=bold,
	style=normal,
%	align=flushright,
	location=hanging,
	width=broad,
	margin=1cm
	]
\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{Sub Item}
  
		This is a description of an item which is within the "Para" item.
  
	\stopdescr
	\startdescr{Sub Item}
 
		Another Sub Item 
  
	\stopdescr
\stopdescr
\startdescr{Short}

	A short item that's not part of that really long "Para" item.

\stopdescr

\stoptext
%%% end

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

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

Is there anyone out there who has a clue as how to fix this?

Re: 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?

mkii or mkiv?

(pdftex is mkii, luatex is usually mkiv)

Re: 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.

\startitemize [n]
  \startitem one
     \startitemize [a]
         \startitem two \stopitem
         \startitem three \stopitem
     \stopitemize
  \stopitem
  \startitem four
     \startitemize [a,continue]
         \startitem five \stopitem
         \startitem six
             \startitemize
                 \startitem seven \stopitem
                 \startitem eight \stopitem
                 \startitem nine \stopitem
             \stopitemize
         \stopitem
     \stopitemize
  \stopitem
  \startitem ten \stopitem
\stopitemize

ok, that makes sense.

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?
