Local and global cross-references

Question

Sections are referenced in a lot of distinct places:

In table of contents. Managed by \tableofcontents In minitocs. Managed by minitoc package In headers. Managed by fancyhdr package Like a leader section. Managed by \section In text. Managed by \ref In tocs and minitocs, because of each section appears below its chapter (wits some indentation) it's not necessary to prefix the section number with the chapter number. The label scope is local; so I need a local renderization. Example:

              1. Chapter One ------------------1
                   1. First section -----------1
                   2. Second section ----------3
               2. Chapter Two -----------------5
                   1. First section ...........5

This means that sections 1.1 and 2.1 must be rendered as section 1.

When we use \section command we know what chapter we are in: it's showed in the headers of te page. So I want also local scope:

         1. First section
                    bla bla
         2. Second section
                   bla bla

In headers I want global scope:

         1. Chapter One                      1.1. First section

In text we can make a crossreference to whatever point of text. So we need global scope:

            See section 1.1 (first section in first chapter)

This is the problem: The default behavior give as global scope every where. But if I redefine \thesection to local scope, then I redefine everywhere.

This is my code:

\documentclass[catalan]{book}
\usepackage{fancyhdr}
\usepackage{nameref}
\usepackage{minitoc}
\usepackage{hyperref}

\makeindex
\dominitoc

%\renewcommand{\thesection}{\arabic{section}}

\renewcommand{\chaptermark}[1]{\markboth{\thechapter\ #1}{}} \renewcommand{\sectionmark}[1]{\markboth{\thechapter.\thesection\ \ #1}}

\fancyhead{}
\fancyhead[LO]{\leftmark}
\fancyhead[RE]{\thechapter.\rightmark}

\pagestyle{fancy}

\begin{document} \tableofcontents \chapter{One}

\minitoc[e]

\section{First section}
\label{sec:A}
aaaaaa \newpage bbbbbbbb \newpage
ccccccccccc

\chapter{Two} \minitoc[e]
\section{Second section}
\label{sec:B}

See sections \ref{sec:A} and \ref{sec:B}

\end{document}

Answer 1

Use \renewcommand{\thesection}{\arabic{section}} to get the numbers beside the section titles right. Changing this otherwise is difficult.

Use \renewcommand{\sectionmark}[1]{\markright{\thechapter.\thesection\ #1}} for the headers.

For the references you can use e.g. zref to set up a "fullsec" reference. But I would find it confusing. And what if you have a subsection 2.1? I would put a \label behind the chapter too and then write something like see section 1 in chapter 2.

Answer 2

Originally I posted a confused question, how-can-i-get-the-chapter-number-like-a-prefix-of-all-references. That question was the genesis of this one.

The answer posted by TH. there is the good answer to the current question
