[Tex/LaTex] Different \section for odd and even pages

conditionalsdouble-sidedpage-numberingsectioning

I would like to make the section titles look different on even and odd pages. I have the following MnWE with the trivial approach. The problem is that you don't know that your section header gets moved to the next page. I even tried to check the oddity of the page number after the section is typeset, but with no success (that is the "After:" text).

\documentclass[a4paper,twoside]{article}

\makeatletter
\let\X@section\section
\def\section#1{%
  \ifodd\c@page\relax
    \X@section{ODD: #1}%
  \else
    \X@section{EVEN: #1}%
  \fi
  \par After:\ifodd\c@page\relax odd\else even\fi \par % <-- for testing purposes
}
\makeatother

\usepackage{lipsum}

\begin{document}

\section{Test section} \lipsum[1]
\section{Test section} \lipsum[1]
\section{Test section} \lipsum[1]
\section{Test section} \lipsum[1]
\section{Test section} \lipsum[1]

\end{document}

Try using the titlesec package. The command \titleformat included in it can take an page=odd or page=even option to give different formatting depending on even or odd page numbers, just like you want.

\usepackage{titlesec}
\titleformat{name=\section,page=odd}{}{ODD:}{.5em}{}
\titleformat{name=\section,page=even}{}{EVEN:}{.5em}{}

in the preamble should give what you want.

[Tex/LaTex] Different \marginparsep for odd and even pages

I would think that accessing the page number at shipout would be robust enough. For this, use the everyshi package. Here is a small trial run:

\documentclass[twoside]{scrartcl}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{everyshi}% http://ctan.org/pkg/everyshi
\usepackage{xifthen}% http://ctan.org/pkg/xifthen

\begin{document}
\EveryShipout{%
  \ifthenelse{\isodd{\value{page}}}%
    {\global\marginparsep=22pt}% Next page is even
    {\global\marginparsep=11pt}% Next page is odd
}

\lipsum[1]
\marginpar[This is a paragraph in the left margin]{This is a paragraph in the right margin}
\lipsum[2-5]
\marginpar[This is a paragraph in the left margin]{This is a paragraph in the right margin}
\lipsum[6-8]
\end{document}

Different marginparsep values for odd/even pages

The key is to make the change \global within \EveryShipout, since it is grouped. You could apply similar modification to the \marginparwidth.

[Tex/LaTex] Different headers for odd and even pages

This request only seems viable in the context of headers. As such, here's a fancyhdr implementation using a standard document class (article):

enter image description here

\documentclass[twoside]{article}
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{fancyhdr}% http://ctan.org/pkg/fancyhdr
\fancypagestyle{mypagestyle}{%
  \fancyhf{}% Clear header/footer
  \fancyhead[OC]{An Author}% Author on Odd page, Centred
  \fancyhead[EC]{A title}% Title on Even page, Centred
  \fancyfoot[C]{\thepage}%
  \renewcommand{\headrulewidth}{.4pt}% Header rule of .4pt
}
\pagestyle{mypagestyle}
\title{A title}
\author{An Author}
\begin{document}
\maketitle
\section{A section}\lipsum[1-20]
\end{document}

twoside is required to allow Odd and Even side varying page styles, but you most likely already use this class option.

Since the \maketitle macro is "self-destructing" and thereby erases \@author and \@title, you need to either make a copy of it into a different macro, or write the author and title in the respective headers manually.
