Sections, cross-references and separators

Sections, cross-references and separators

[Duncan Hothersall]

Dear all,

I am confused. Here is a minimal version of my problem:

---
\setupheads[separator=] %<-- this can't be right
\setupreferencing[state=start,chapternumber=yes,global=yes]
\setupsection[section-1][conversion=Characters]
\setupsection[section-2][previousnumber=yes]
\setuphead[part][placehead=yes,resetnumber=yes,page=no]
\setuphead[chapter][page=no]
\setuphead[section][number=no]
\setuppagenumbering[partnumber=no]
\starttext
\placelist[part,chapter,section][alternative=b,partnumber=no]
\part[ptest]{Ptest}
\chapter[ctest]{Ctest}
\section[stest]{Stest}
See \in{Chapter}[ctest] (should say A1) and \in{Figure}[ftest] (should 
say A1.1).
\placefigure[here][ftest]{Ftest (should be called A1.1)}{}
\stoptext
---

What I am aiming for is a style where:
    Parts are labelled A, B, C [done],
    Chapters are labelled A1, A2, A3 [done, but...],
    Cross-references to Chapters call them A1, A2, A3 [not done: I'm 
getting A.1]
    Figures are labelled A1.1, A1.2 [not done; I'm getting A.11 (eek!)]
    Cross-references to Figures call them A1.1, A1.2 [not done: I'm 
getting A.11]

It seems to me that the line
\setupheads[separator=]
can't possibly be right and is almost certainly causing the missing dot 
in the Figure number, but it was the only way I could find to remove the 
dot between the A and the 1 in the chapter label. I have toiled a little 
with the core-ref code and cannot fathom how any of the variety of uses 
of the word "separator" make sense, or indeed if they really have 
anything to do with it... :-)

I'm testing on the garden, using pdfTeX. I'd be *really* grateful for 
some help with this one.

Thanks,

Duncan

In this case it is easier to make the actual chapter number include
the 'A'. That way, you won't have to worry about "separator" at all
(which is good, because its use is confusing).

Try this:

@@ -1,4 +1,4 @@
-\setupheads[separator=] %<-- this can't be right
  \setupreferencing[state=start,chapternumber=yes,global=yes]
-\setupsection[section-1][conversion=Characters]
-\setupsection[section-2][previousnumber=yes]
+\def\Mychapter#1{\convertnumber{Characters}{\getvalue{@@sesection-1}}#1}
+\defineconversion[MyChapter][\Mychapter]
+\setupsection[section-2][conversion=MyChapter]


Question for Hans: is there a nicer way to get at the part number?
The explicit @@se is a bit too low-level for my taste ...

Best wishes,
Taco

Ah, thanks so much Taco, never thought of that approach - works like a 
charm. (I also thought that macros with @ in their names could only be 
used in protected mode, so that's two things I have learned for the 
price of one.)

Do you think this is general interest enough to warrant wikifying?

Thanks very much.

Duncan

As far as TeX is concerned, I am not actually using the macro myself,
just mentioning its name. The \getvalue macro then constructs the actual
macro name internally. That works always, but usually macro calls look
funny when used in that way.

I just found  \rawsectionnumber, so with this change it should also work 
(and look less low-level, which is good if you want to wikify it):

   \def\Mychapter#1%
      {\convertnumber{Characters}{\rawsectionnumber{section-1}}#1}

Best wishes,
Taco
