# How could glossaries' numberlabel use the manually defined number of Sections(or other Sectional Units)?

I am using 'glossaries' to make index after my book, I set the numberlist to section, so the number of the section will in the numberlabel. eg:

                               INDEX
Unix, a multitasking, multi-user computer operating system  1
Unix-like, operating system is one that behaves in a manner similar to a Unix system 2


It means that the word Unix is in the section 1, the word Unix-like is in section 2.

But right now I have some sections whose names are not genarated by default, they are defined manually by the commands as follows:

\section*{2a Linux}


The meanest code is as follows:

\documentclass{book}
\renewcommand\thesection{\arabic{section}}
\usepackage[counter=section]{glossaries}
\makeglossaries

\newglossaryentry{Unix}{
name={Unix},
description={a multitasking, multi-user computer operating system}
}
\newglossaryentry{Unix-like}{
name={Unix-like},
description={operating system is one that behaves in a manner similar to a Unix system}
}
\newglossaryentry{Linux}{
name={Linux},
description={Linux was originally developed as a free operating system}
}
\newglossaryentry{FreeBSD}{
name={FreeBSD},
description={a free Unix-like operating system, an operating system}
}
\newglossaryentry{Windows}{
name={Windows},
description={a series of graphical interface operating systems}
}
\newglossaryentry{Mobile Operating System}{
name={Mobile Operating System},
description={the operating system that operates a smartphone...}
}

\begin{document}
\section{Unix}

\section{Unix-like}
A Unix-like \glsadd{Unix-like}(sometimes referred to as UN*X or *nix) operating system is one that behaves in a manner similar to a Unix system, while not necessarily conforming to or being certified to any version of the Single UNIX Specification.

Linux \glsadd{Linux}was originally developed as a free operating system for Intel x86-based personal computers. It has since been ported to more computer hardware platforms than any other operating system.

FreeBSD \glsadd{FreeBSD} is a free Unix-like operating system descended from AT\&T UNIX via BSD UNIX.  Although for legal reasons FreeBSD cannot be called "UNIX".

\section{Windows}

So, if some entries are in these manually defined sections, the 'glossaries' can not read the number of setions then the numberlists of these entries don't work. Right now it looks like:

                            INDEX
Unix, a multitasking, multi-user computer operating system  1
Unix-like, operating system is one that behaves in a manner similar to a Unix system 2
Linux,Linux was originally developed as a free operating system 2
FreeBSD, a free Unix-like operating system, an operating system  2
Windows, a series of graphical interface operating systems 3
Mobile Operating System, the operating system that operates a smartphone... 3


Actually, It should like this:

                            INDEX
Unix, a multitasking, multi-user computer operating system  1
Unix-like, operating system is one that behaves in a manner similar to a Unix system 2
Linux,Linux was originally developed as a free operating system 2a
FreeBSD, a free Unix-like operating system, an operating system  2alpha
Windows, a series of graphical interface operating systems 3
Mobile Operating System, the operating system that operates a smartphone... 3delta


How to resolve these problems? How to make 'glossaries' can read the number of sections which were defined manually correctly?

The glossaries package writes the location as the value of the counter assigned to the particular entry, so you can't just specify a particular location as a string. In addition, makeindex only understands a limited number of location styles (arabic, roman and alph), so if you have any location that doesn't fit that style you will have to use xindy. Here's a possible solution:

\documentclass{book}
\renewcommand\thesection{\arabic{section}}
\usepackage[counter=section,xindy]{glossaries}

\newcounter{sectionalph}
\newcounter{sectiongreek}

\renewcommand{\thesectionalph}{\thesection\alph{sectionalph}}
\renewcommand{\thesectiongreek}{\thesection\greekstring{sectiongreek}}

\newcommand{\greekstring}[1]{%
\ifcase\value{#1}\relax
\or
alpha%
\or
beta%
\or
gamma%
\or
delta%
\or
epsilon%

There are still two issues: 1.a suspect BUG. The parameter \alph doesn't work fine in my MAC OSX, when the counter is bigger than 6, in the section it is 2f, 2g, 2h, there will be something wrong. So I have to use \newcommand{\alphstring} and define \GlsAddXdyAlphabet{alph} from a to z manually same as greekstring and greek. –  WonderTree Oct 14 '12 at 3:37
@WonderTree \newcounter has an optional argument (which comes after the mandatory argument) where you can specify the parent counter. More detail at (dickimaw-books.com/latex/novices/html/counters.html) and (tex.ac.uk/cgi-bin/texfaq2html?label=addtoreset) –  Nicola Talbot Oct 15 '12 at 7:35

I think it need not concern Makeindex or Xindy. These entries are not in the Sectional Units which are unnumbered, they are in the Section Units which have been manually numbered, eg 2a, 2alpha, 3delta etc. They were actually defined by author with for example

\section*{2a  Linux}


So the solution is very simple, since they need be defined manually, then we can add one parameter to supply the number of these sectin for glossaries. If the number of this section is '2a', it could look like in the preamble:

\newcommand\mysection[2]{
%----------------------

%----------------------
}


There parameter #1 is the manully defined number of the section, #2 is its' name. We just need add a new function '\add-glo-diy-number-of-sec' in package 'glossaries' to make it true

that glossaries can read the #1, and in the tex we just need

\mysection{2a}{Linux}


then, the glossaries can use the location---- 2a

All in one, we just need add a new funcion

 \addglodiynumberofsec


or in some other names in glossaries. It's resolved.

But I'm not a programmer, I can't modify the code of glossaries, so here asking for help.
