Indexes

[Simon Pepping]

Hi,

I have a few questions regarding indexes.

1. \completeindex generates a numbered chapter. Is there a way to make
   this unnumbered?

2. Is there a way to suppress the index when there are no index terms,
   in other words, can I let Context detect whether there are index
   terms? I tried \doifmode{*index}{\completeindex}, but that does not
   seem to do what I want.

3. In the recent beta, which I downloaded on 11 May, \completeindex
   generates an erroneous ToC entry, viz. titleindex. I traced this
   back to an \xdef that does not do what it probably was meant to do:

\convertmeaning #1\to ->\bgroup \honorunexpanded \dontexpandencoding \xdef \@@g
lobalexpanded {#1}\xdef \@@globalexpanded {\@@globalexpanded }\egroup \convertc
ommand \@@globalexpanded \to 
#1<-\headtext {\v!index }

\headtext ->\let \handletextprefix \firstoftwoarguments \dogetupsometextprefix 
\headlanguage \c!titel 

\firstoftwoarguments #1#2->#1
#1<-\dogetupsometextprefix 
#2<-\headlanguage 

\c!titel ->\c!internal! titel
{\string}

\v!index ->index
{\xdef}

\@@globalexpanded ->\let \handletextprefix \dogetupsometextprefix titel{index}

The \let does not work well in \xdef; instead, \firstoftwoarguments is
expanded. I cannot think of a way to correct this.

Regards,
Simon

numbered sections become unnumbered when used in:

\startbackmatter

\stopbackmatter

(als also in \startfrontmatter .. \stopfrontmatter; you can guess what 
happens in \startappendices \stopappendices; this is why sectionblocks are 
there)

you're nearly there:

first do a trial run:

   \determineregistercharacteristics[index][optional settings]

next test for a system mode:

   \doifmode{*register}

hm, here the toc entry has: \headtext {\v!title}

so, you probably have turned toc-expansion on,

in lang-lab, you can change the def :

\unexpanded\def\headtext
   {\let\handletextprefix\firstoftwoarguments
    \dogetupsometextprefix\headlanguage\c!titel}

(so, add \unexpanded; i'll add it too, since it does not harm compatibility)
