Registers

< Structurals | References > (It's also in the manual at "Registers")

Basics

Putting a word into the index as simple as \index{word}. (Always type \index before the word you refer to!)

To sort e.g. \ConTeXt under "C", you write \index[CONTEXT]{\ConTeXt}.

If you need multiple levels (up to three), use "+" or "&" separators like in \index{beans+baked}.

You get a cross reference in your index with \seeindex like in \seeindex[CONTEXT]{\ConTeXt}{\TeX} (ConTeXt: see TeX).

To typeset the index, use \placeindex (without title) or \completeindex (with titling).

Example

My \index{dog}dog is a \index{dog+bullterrier}bullterrier named \seeindex{Dolly}{Underware}Dolly.
He doesn't like \index{cat}cats.
There are a lot of \index{cat+stray}stray cats, but only a few of them are \index{cat+Siamese}Siamese.

\placeindex


Styling the Index

\setupregister[index] is your friend. \placeindex and \completeindex take the same options.

You can also style single entries with the :: syntax like this (from the manual):

\setupregister[index][form][pagestyle=bold,textstyle=slanted]
\setupregister[index][tb][textstyle=bold]
\setupregister[index][nb][pagestyle=bold]
\setupregister[index][hm][pagestyle=slanted]

\index{tb::foot+squarefoot} % text in "tb" style
\index[nb::]{squareroot} % number in "nb" style
\index[hm::root]{$\srqt{2}$} % number in "hm" style, sorted at "root"


More Registers

\index is only one special case of \register. You can define as much different registers as you like:

\defineregister[singular name][plural name], e.g.

\defineregister[mouse][mice]
\setupregister[mouse][style=\ss]

\mouse{rat}

\placemouse


(Don't know if the plural form is used anywhere...)

Tricks

• \startregister[mymouse]{mouse} ... \stopregister[mymouse]: to mark several pages for the same entry; becomes e.g. "mouse 12--16". Note that if you have two or more of these ranges, you need them to have different [key] values to stop the system treating them as part of a great big range. So, use \startregister[mymouse1]{mouse} ... \stopregister[mymouse1] and then \startregister[mymouse2]{mouse} ... \stopregister[mymouse2].
• \writetoregister (sometimes needed to avoid macro expansion issues)
• A register per chapter: \placeregister[index][criterium=chapter]
• Place a word in text and index: \def\Tindex#1{\index{#1}#1} -- Please someone enhance this to get space correction, [] sorting etc.!

Coupled Registers

This is a special feature for documents that are only used on screen: Make a word clickable to jump to the index, the first or last occurrence.

Enable it with \setupregister[index][coupling=yes]. Substitute \index with \coupledindex and enjoy!
