How to configure fancyhdr depending on the document class

How to configure theorems depending on the document class?

I would like to have if the book class is loaded but if the article class is loaded. Can I do this with some sort of conditional?

I tried, but failed.

\makeatletter%
\@ifclassloaded{book}{%
  \renewcommand{\chaptermark}[1]{\markboth{#1}{}}
  \renewcommand{\sectionmark}[1]{\markright{\thesection\ #1}}
  \fancyhead{}
  \renewcommand{\chaptermark}[1]{\markboth{\thechapter.\ #1}{}}
  \fancyhead[LE]{\bfseries\leftmark}
  \fancyhead[RO]{\bfseries\rightmark}
  \fancyfoot{}
  \fancyfoot[LE,RO]{\bfseries\thepage}
  \fancyfoot[LO,RE]{Régis}
  \renewcommand{\headrulewidth}{0.5pt}
  \renewcommand{\footrulewidth}{0.5pt}
  \addtolength{\headheight}{0.5pt}
  \fancypagestyle{plain}{%
  \fancyhead{}
  \renewcommand{\headrulewidth}{0pt}
  }
  \typeout{Using book class.}%
}{%
\@ifclassloaded{article}{%
%   \renewcommand{\chaptermark}[1]{\markboth{#1}{}}
  \renewcommand{\sectionmark}[1]{\markright{\thesection\ #1}}
  \fancyhead{}
%   \renewcommand{\chaptermark}[1]{\markboth{\thechapter.\ #1}{}}
  \fancyhead[R]{\bfseries\rightmark}

Didn't we just answer an identical question of yours like this: How to configure theorems depending on the documentclass? This is (another) duplicate of Which document class is being used? — Alan Munn, Aug 11 '11 at 20:07
Alan is correct. Just inserting the appropriate sections of your code into the solution at How to configure theorems depending on documentclass should work. — Peter Grill, Aug 11 '11 at 20:13
can not you have two environments \makeatletter% on the same file? — Regis Santos, Aug 12 '11 at 04:13
The #1 is intended to refer to the first parameter to a macro call. Here you are not defining a macro so it doesn't have meaning. — Peter Grill, Aug 12 '11 at 04:13
There should not be any problems with multiple uses of \makeatletter ... \makeatother. I don't think you can nest then but have not tried that. — Peter Grill, Aug 12 '11 at 04:14
@Regis Two problems: (i) You are missing a brace in the line \typeout{Using article class} (needs one more closing brace) (ii) the macro\QUITHERE` is not a real macro: it was a pseudo-code macro that Peter used in his answer, so remove it. — Alan Munn, Aug 12 '11 at 05:15
@Regis Ideally what you're trying to do should be done by passing options to a package, not by having a huge preamble like this. You should read the documentation for writing classes texdoc clsguide for some information on this. — Alan Munn, Aug 12 '11 at 05:16

This should get you started. Just add the appropriate settings to BookHeader, ArticleHead, and ReportHead. Within these three you can use #1 to refer to what was passed to \SetHeaders.

The following is intended to exit if a class other than book or article or report is used. You can remove the \QUITHERE macro if that is not desired.

\documentclass{article}

\newcommand*{\BookHeader}[1]{% Add any customizations for book class here.
  \typeout{Using book class.}%
}%

\newcommand*{\ArticleHead}[1]{% Add any customizations for article class here.
  \typeout{Using article class.}%
}%

\newcommand*{\ReportHead}[1]{% Add any customizations for report class here.
  \typeout{Using report class.}%
}%

\makeatletter%
\newcommand*{\SetHeaders}[1]{%
    \@ifclassloaded{book}{\BookHeader{#1}%
    }{\@ifclassloaded{article}{\ArticleHead{#1}%
    }{\@ifclassloaded{report}{\ReportHead{#1}}{%
      \typeout{Error: Unsupported class: 'article' or 'report' or 'book' are suported.}\QUITHERE
    }}}%
}%
\makeatother%

\SetHeaders{foo}%


\begin{document}
Testing...
\end{document}

This is definitely easier to read code. (The original code also worked; see my comment above.) Also, @Regis Peter has the pseudo-code macro \QUITHERE; this document will fail inelegantly if an unsupported document class is used. – Alan Munn Aug 12 '11 at 05:20
How to use \renewcommand{\chaptermark}[1]{\markboth{\thechapter.\ #1}{}} for appear 1.foo (name of chapter) without CHAPTER 1.foo. Is failed in Report. – Regis Santos Aug 12 '11 at 05:24
@Alan: Thanks, have added the comment about \QUITHERE. I find it very useful to exit for cases that I have not yet handled in the code. – Peter Grill Aug 12 '11 at 05:25
It's also possible to use \PackageError{<package name>}{<error text>}{<help text>} inside a document. – Alan Munn Aug 12 '11 at 06:05
