Itemize Prefixes

Itemize Prefixes

[Kip Warner]

[-- Attachment #1.1: Type: text/plain, Size: 726 bytes --]

Hey list,

I'd like an itemized list using the following format...

Article I ...
Article II ...
Article III ...

...and so on. I've tried defining the behaviour with...

\defineenumeration[article]
    [location=top,
    text=Article,
    between=\blank,
    before=\blank,
    after=\blank]
\setupenumerations[article][R]

...but the problem is that after a list of items provided with matching
\startarticle \stoparticle pairs, the last count persists to the next
list of items which should start at 'I' again. I am assuming I am not
doing this correctly and would appreciate any suggestions.

Use itemgroup rather than enumerations.

Thanks Aditya, but could you give me an example of how to do this? As
usual, I am not able to take much away from the ConTeXt wiki. Sorry.

Why is another \setupitemgroup being used here when broad,fit could have
been merged with its previous one that both affected the article
itemgroup?

How do I add an extra line after the header? I tried adding another
\blank to the after parameter of \setupitemgroup, but it didn't seem to
use it.

Lastly, how do I change the text colour of the item header? I tried the
following to no avail,

\setuphead
  [article]
  [color=colour_head]

Another thing I just noticed is that using \startarticle[start=20]
before an item block doesn't always begin counting at that. On some
blocks it starts where it should at 'start', and other times it ignores
it and starts from 1 again.

Thats how itemgroup are configured. You cannot mix assignments (key=value) 
with options.

You can use

\setupitemgroup
     [article]
     [command=\blank]

(in this case you can remove the second configuration (the one with broad, 
fit) or explicitly set width=0).

Why do you expect \setuphead to change the way itemgroups behave? Use


\setupitemgroup
    [article]
    [color=...]

I don't follow. What is the difference between this,

\setupitemgroup
   [article]
   [
     left={Article },
     stopper=,
     symbol=R,
     before=\blank,
     after=\blank,
     distance=0.5em,
   ]
\setupitemgroup
   [article]
   [broad,fit]

, and this?

\setupitemgroup
   [article]
   [
     left={Article },
     stopper=,
     symbol=R,
     before=\blank,
     after=\blank,
     distance=0.5em,
     broad,
     fit
   ]

That worked. Thanks.

> Why do you expect \setuphead to change the way itemgroups behave? 

Because I can't make any sense of the thousands of pages of ConTeXt
documentation scattered everywhere with little apparent rhyme or reason
to its usage and with everything other than whatever it is that I seem
to need present in them.

I tried that and it did nothing.

\definecolor[colour_text][r=0.754,g=0.516,b=0.324]
\setupitemgroup
    [article]
    [color=colour_text]

ConTeXt checks if the argument of \setupitemgroup has an assignment 
(key=value), then it calls a version of \setparameters; otherwise it calls 
a version of \processcommalist. So, if you use assignments and options in 
the same command, the options get ignored.

All ConTeXt commands behave like this.

If you define a command using \define<...>, then you configure it using 
\setup<....>. Other than a few exceptions, that's how it is.

That's probably buried deep in the documentation somewhere and in that
sense it's my fault. But at the same time, that's got to be the most
counterintuitive syntax of any language I've ever used.

It's ok, I found the problem. The code works, but I was setting the
wrong color value ;)
