Hi,
In order to trash the need of tex2xindy, I wrote a small package,
which provides a new indexing-behavior. By using this package,
the index file (.idx) will contain the raw index.
The package provides the command
\indexindy[<options>]{<Layers>}
<options> is a list of one (or more) of the following:
attr=<attribute> key is indexed with :attr "<attribute>"
open-range " " " " :open-range
close-range " " " " :close-range
xref=<string-list> " " " " :xref (<string-list")
<Layers> is the string-list for the layers in the following syntax
<layer0>,<print-key>;<layer1>,<print-key>
There are another two commands to generate different location-refs:
\newindexstyle{<name>}{<reference>} : define a style
\indexstyle{<name>} : select a style
Thus,
\newindexstyle{chapter}{\thechapter-\thepage}
\indexstyle{chapter}
will generate a different location reference for the following
indices (e.g. 1-5, 2-7, A-6)
Examples.
--------
The input
\indexindy[attr=definition]{Euler}
\indexindy[open-range,attr=definition]{Euler,\textsc{Euler}}
\indexindy[attr=see,xref="Euler"]{Personen;Mathematiker}
\indexindy[close-range,attr=definition]{Euler,\textsc{Euler}}
\indexindy{Layer 0;Layer 1,\textsc{Layer 1};Layer 2}
\indexstyle{chapter}
\indexindy{Index the comma{,} too}
leads to the output (assuming random locrefs :)
(indexentry :tkey ( ( "Euler" ) ) :attr "definition" :locref "11")
(indexentry :tkey ( ( "Euler" "\\textsc{Euler}" ) ) :attr "definition"
:open-range :locref "12")
(indexentry :tkey ( ( "Personen" ) ( "Mathematiker" ) ) :attr "see"
:xref ("Euler"))
(indexentry :tkey ( ( "Euler" "\\textsc{Euler}" ) ) :attr "definition"
:close-range :locref "17")
(indexentry :tkey ( ( "Layer 0" ) ( "Layer 1" "\\textsc{Layer 1}" ) ( "Layer 2" ) )
:locref "11")
(indexentry :tkey ( ( "Index the comma{,} too" ) ) :locref "1-11")
You should note, that the backslash \ in the input is converted to \\ automatically.
But as you see, there are some problems left, which I couldn't solve yet.
1. The input {,} leads to an raw-entry containing {,}.
I'd like to convert this to , without the brackets.
2. There is a minor problem on the spacing. I'd like a output
like :tkey (("Layer 0") ("Layer 1" "\\textsc{Layer 1}"))
3. The xref-tag is specified in another form than the key-tag.
I'd like to use the same syntax, but don't know how to
combine keyval.sty with this syntax.
4. Currently the style interferes with LaTeX-\index, since
I redefine some internal commands. Anyone there, who think
this might cover errors?
Thus, the above example leads (using a special .xdy-file for \textsc{}, ...)
\begin{theindex}
\item \textsc{Euler}, \textbf{11}--\textbf{17}
\indexspace
\item Index the comma{,} too, 11
\indexspace
\item Layer 0
\subitem \textsc{Layer 1}
\subsubitem Layer 2, 11
\indexspace
\item Personen
\subitem Mathematiker, \see{Euler}
\end{theindex}
Since I am not to deep into TeX, I would be glad if a wizard could
check the code, which I will append to this message. So would I,
if someone would help me solving the mentioned "problems".
Sorry, that the code isn't documented, nor a .dtx-file. But cause
this is only a first attemp, I spend the time on the code instead
of a documention.
Best Regards,
Andi
