descriptions and enumerations

descriptions and enumerations

[Guy Worthington]

I'm having trouble developing a coupling.  

In the code below, you'll see a skeleton example, after which
follows a discussion, and then a bit more code.  I'm trying to show a
that each code snippet is coupled to the first example by using an 
\exampleContinued macro.

\defineenumeration
 [example]
 [location=serried,
  text=Example,
  before=\blank,
  after=\blank,
  way=bychapter,
  style=italic]

\definedescription
 [exampleContinued]
 [location=serried,
  width=fit,
  distance=1em,
  text={Example~\headnumber[chapter].\nummer[example] 
            (continued)},
  before=\blank,
  after=\blank,
  style=italic] 

\setupcolors[state=start]

\starttext

\chapter{Introduction}

\input tufte

\example[ex:simpleExample] A Simple Example

\startJV
// A very simple applet
import java.applet.Applet;
import java.awt.Graphics;

/** This applet just says "Hello World"! */
public class HelloWorld extends Applet {
    ...
}
\stopJV

\input tufte

\exampleContinued[ex:simpleExample:1] The paint() method

\startJV
    /** Just says "Hello World
     * @param g
     */
    public void paint (Graphics g) {
        g.drawString("Hello World", 25, 10);
    }
\stopJV

\stoptext

You'll see that the example (continue) line is all garbled, with the
first word (in this case "The") set in wrong type and also in the
wrong place.  

I'm hoping someone can unravel the mess.

warning: space gets eaten after \nummer[...]. I don't think that this
is the expected behaviour, but it is the way it is.

this is because \description takes one argument:

 \description{...}...\par


{...}		   <text>
...		   <text>


the "The" is taken (why not only the "T"??) as the argument. See
cont-en?.pdf chapter 10.

Most likely there is some more clever or elegant way. But probably too
clever for me.

It's cleaner than my partial solution (and it works to boot).  In my
books I'd call that elegant.
