\definehead with some extra's

\definehead with some extra's

[Gilbert van den Dobbelsteen]

I have a nice problem:

  \definehead[MYMONTH][paragraph]

Ok, Now I want to suppress the generation of heads:

  \setuphead[MYMONTH]
    [command=\mycommand]

  \def\mycommand#1#2#3{}

Ok, that works, but it has an expected side effect: The heads don't show up
in the contents. After studying several things I found out that #2 contains
the commands for putting things in the .tui file. So I want to execute the
commands to create the correct entries in the .tui file, but I do not want
to typeset anything at all. Can I do something like:

  \writetolist[MYMONTH][blahblah]

Or do I need to hand-code the stuff, something like this:

\definelist[MYLIST]

  \def\MYMONTH#1{%
    \writetolist[MYLIST][#1]}

(Sorry about the syntax, it is probably not correct CONTeXt, and the
arguments are probably not in the correct order).

Gilbert.

This feature is already built in for quite some years:

\definelist[MyMonth]

\writetolist     [MyMonth]{a}{b}  % two entries 
\writebetweenlist[MyMonth]{a}     % one entry, e.g. \blank or \page

\placelist[MyMonth]               % or [MyMonth,MyDay,..]

You can set up lists (assign commands to handle the entries). Lists obey
the section numbering mechanism, so you can ask for local ones.
Actually, this is how tables of contents etc are produced. 

Lots of surprises still waiting for you ...

Can you try the attached cont-new.tex? I didn't check out the other
options, but it looks like a double attributes handling takes place. The
attached version removes the outer attribute handler. These macros need
a bit cleaning up, I admit. 

Can you check if things still work ok? 

(There is a \def\kap##1{##1} still somewhere; has to do with complicated
interactive stuff; can probably be removed.)

Bug in \defineenumeration

[Taco Hoekwater]

Hello Hans,

At least my version of context exhibits a rather nasty bug in 
enumerations: \cap prevents the reading of the optional argument to
the defined command.

Try this little document (sorry, nl version):

\doornummeren[rommel][kopletter=kap]
\starttekst

\startrommel [-]
Wat tekst
\stoprommel

\tracingnone

\rommel[-]
Nog wat text

\stoptekst

How can I fix this?

Greetings, Taco

Getthe latest from www.pragma-ade.nl.  A few days ago I added a feature
(cross linking enumerations was already supported, but I added global
cross linking).

Let's hope this code is rather ok. We use enumerations/descriptions a
lot, and in general the code is ok (like most old context stuff).
Looking forward to tantilizing feature requests. 

What are enunciations? What problems do you expect? The kap is among the
most troublesome concerning attributes.

I haven't installed the new one from tetex yet. 
Mine is half-februari somewhere.

This is ok I think, but i'm not certain (I get an error related to
numbers, but it might be something completely different). 

Anyway, I'm going home: done enough for today. I am using the
\defineenumeration to handle scientific enunciations, btw. This
obviously has not been done before, and it is quite likely that there
will be new/more bugs/feature requests to report soon. 

Greetings, Taco

Sorry, but it is not OK. 

\doornummeren[definition][tekst=Definition]
\steldoornummerenin[definition] % some more here
	[plaats=aanelkaar,kopletter=kap,
	 paragraafnummer=ja,wijze=perdeel]

\startdefinition
....
\stopdefinition

This tries to evaluate the counter \@@ddDEFINITION@@ddnummer when
typesetting (as well as \@@ddDEFINITIONlinks etc. etc.).

	\doornummeren[][plaats=aanelkaar,breedte=passend]

This is too literal in it's interpretation of 'fitting'. I'd like at
least one space between the number and the first char of the following 
paragraph.

	\doornummeren[][wijze=perdeel,paragraafnummer=ja]

Does not give the desired result, which is:

	Theorem 2.1 % 1st global theorem, in paragraph 2
	Theorem 3.2 % 2st global theorem, in paragraph 3

etc. Instead I get:

	Theorem 1 % 1st global theorem, in paragraph 2
	Theorem 2 % 2st global theorem, in paragraph 3

	\doornummeren[theorem][tekst=Theorem]
	\doornummeren[lemma][theorem][tekst=Lemma]
	\steldoornummerenin[...][wijze=perparagraaf,paragraafnummer=ja]

Only works out OK if the first thing I encounter is indeed a
theorem:

	Theorem 2.1 % 1st theorem, in paragraph 2
	Lemma   2.2 % 1st lemma, in paragraph 2

Otherwise, I'll get:

	Lemma     1 % 1st lemma, in paragraph 2 
	Theorem 2.2 % 1st theorem, in paragraph 2

Theorems, propositions, corollaries etc. Problems as above.

Indeed. The \uppercase in \kap is the troublemaker. There is no easy way
around this, which is (see source) why \def\kap##1{##1} was there inside
this macro. I forgot to adapt that one to an update. I now simply
disable the kap option, because the proper solution (there are
workarounds possible, but they should work at all levels and thereby
increase the code a lot) is to let eetex provide something \nocase{},
which, when issued inside \uppercase or \lowercase, disables the
conversion.   

Suggestion: say  [...,tekst=DEFINITION,letter=\tx,...] instead and you
will get what you want: an uppercase label is a smaller typeface.

Use   breedte=ruim (width=broad)   instead.

The current numbering scheme is based on a tree like structure. Some
commands permit turning prefix numbers on/off, others don't. This has to
do with forcing consistency. 
In your case, paragraaf=ja does not work that way. Would it do, then
something else would be inconsistent. When I come to 'documenting' and
'optimizing' this part of context, I'll extend the mechanisms involved
to support this kind of reverse prefixing (down->top settings). 

For the moment, you need to play around a bit with numbers yourself. A
paragraph is a section-3 level heading. You can turn the prefix off at
every level. Next you can call for the paragraph number. By assigning it
to 'links' (left) it is put left of the number, and the period is added
there too. 

Concerning the related things: Define one parent and let all the others
hang on that one. The kap can be realized by using uppercase strings and
switching to the smaller typeface. 

Remind me to put this example in the manual!

\doornummeren

  [tekst=DEFINITION,

links={\stelsectiein[sectie-3][vorigenummer=nee]\kopnummer[paragraaf].},
   letter=klein,
