Hans Hagen: "an index entry needs an anchor" (Mail Archive 3/19/2014)

[Rudolf Bahr]

Hi,

LaTeX "index" command doesn't need an anchor in order to print the page number.

Sometimes you can't give the ConTeXt-Command "index" any anchor. Think of an
external figure on a page and nothing else, without any text. When I say, for instance:

\index{Brigitte Bardot}\strut

I get a correct index, but an unsolicited extra empty page, too. What could be a solution?
My ConTeXt version is: "ConTeXt  ver: 2014.11.12 21:46 MKIV beta  fmt: 2014.11.14"

Greetings, Rudolf

i'm pretty sure that any index mechanism that is supposed to provide the 
right page does a delayed write, so some kind of anchoring is there

(you could try \index{...}\null or maybe \setregisterentry)

Sorry, Hans. \index{...}\null isn't the solution either: I get an unwanted additional empty page,
but no pagenumbers in the index. 

Regarding \setregisterentry I cannot say very much because I didn't find enough information 
about that topic:  I fear I have to set in advance the appropriate page numbers and cannot 
use ConTeXt's page number facilities.

Ok, I shall look for other solutions, thank you.
