Chapter numbering that does not follow a regular pattern

Chapter numbering that does not follow a regular pattern

[jbf]

Hi there,

I have a situation where numbered chapters are occasionally interspersed 
with unnumbered chapters, so, for example, it might be:

1 First chapter title with number

   second chapter title unnumbered

2 Second chapter title with  number

3 Third chapter title with number

-----------

Now, I can achieve what I want by putting something like the following 
for a 'normal' chapter (by which I mean one that needs to be numbered, 
but would otherwise be out of sequence):

\chapter[title={\sc My chapter title that needs a different 
number},ownnumber=2]

And in the case of the interspersed 'other' chapter (that is, the one 
that follows Chapter 1 numbered, still needs a title, but no number, and 
therefore breaks the normal number increment), I define 'mychapter' in 
the initial setup, then:

\mychapter[title={\sc MY UNNUMBERED CHAPTER TITLE},number=no]

-----------

But I was wondering if there was a way that I could achieve the result I 
want in the initial setup for the two different kinds of chapters. If it 
were a regular pattern, e.g. 1 chapter, unnumbered chapter, 2 chapter, 
unnumbered chapter, that might be easier to do, but in the situation I 
am dealing with, there is not this regularity.

You may well tell me that since I can achieve what I want as described 
above, that should suffice. I will be happy to have that confirmed. On 
the other hand, someone may have a more elegant suggestion in the 
initial setup that enables me to call in the specific kind of chapter I 
need at the time in a simpler way.

Julian

Use \title (or \starttitle[title={}]) for unnumbered and \chapter (\startchaper) for numbered.

If you need the unnumbered chapters in your ToC, you must add them like \setupcombinedlist[content][list={chapter,title}]

You can setup most options for both using \setuphead[chapter,title][...]

That's obviously much simpler! I was under the impression that 'title' was
only for use in front matter, or that if I used it elsewhere, then it
didn't show the number but that the next use of 'chapter' would increment
as if it had a number. I was wrong!

titles normally don't end up in the toc, chapters do ... in frontmatter 
chapters are unnumbered too so it's kind of a combination: 
numbers/unnumbered and tocontents/nottocontents depending on the 
'matter' at hand
