Background
Looking to indent an arbitrary n-level hierarchy within an index and have hyperlinks for the final item, using the memoir class and pdfTeX 3.1415926-2.4-1.40.13 (TeX Live 2012).
For example:
\index[classification]{Anthropoidea!Hominoidea!Hominidae!Homo!sapiens}
Should produce:
Where the 2 in "sapiens, 2" is hyperlinked back in the document (PDF).
Problem
First, makeindex
can only nest 3-levels deep. Second, xindy
is incompatible with hyperref; from the man page:
In particular, this means that by default the LaTeX package "hyperref" will create raw index files that cannot be processed with xindy. This is not a bug, this is the unfortunate result of an intented [sic] incompatibility. It is currently not possible to get both hyperref's index links and use xindy.
Question
How would you create hyperlinked indexes that nest to an arbitrary depth?
Example Document
A minimal document might resemble:
\documentclass{memoir}
\usepackage{filecontents}
\begin{filecontents*}{style1.xdy}
(markup-index :open "~n\begin{theindex}~n"
:close "~n\end{theindex}~n"
:tree)
(markup-indexentry :open "~n \sssssubitem " :depth 5)
\end{filecontents*}
\long\def\lettergroup#1\item{\item\textbf}
\let\lettergroupDefault\lettergroup
\usepackage{makeidx}
\makeindex
\begin{document}
Start
\index{Anthropoidea!Hominoidea!Hominidae!Homo!sapiens}
End
\printindex
\end{document}
However, this does not produce the correct results, when run with:
pdflatex file.tex; texindy file.idx; pdflatex file.tex
