[Tex/LaTex] New class base on book class with options

document-classesdocumentclass-writing

I created a class of my own that uses book as base class.

\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{manuscript}[2013/03/23 Creative writing manuscripts class]
\LoadClass[a4paper,12pt,oneside]{book}

The problem is that I want to be able to choose paper size and other options the book class has. The only way to do that is to redefine all the options the book class already has with the same values and pass it when I load the base class?

Also, let's say I want to add a language option to my class so that if I choose Portuguese, for example, I want to load babel with portuguese.

How can I create use the options already defined in book class to change the values of that class and use my new Portuguese option to load babel with that language.

You can use

\DeclareOption*{\PassOptionsToClass{\CurrentOption}{book}}

to pass all not used option to your basic class book when it is called with \LoadClass{book}.

To give you a better advice you should add a MWE what you doing in your class.

In order to do this correctly you should create an if-switch or boolean which is modified by the oneside and twoside options of your package, which then pass the final option to memoir. Note that you should process or execute your options before loading another class or package.

\NeedsTeXFormat{LaTeX2e}[1999/12/01]
\ProvidesClass{mythesis}[01/01/2011, v1.0, my own thesis class]
\RequirePackage{ifthen}
\RequirePackage{calc}
\AtEndOfClass{\RequirePackage{microtype}}
%
\newboolean{@myopti}
\setboolean{@myopti}{false}
\newboolean{@myoptii}
\setboolean{@myoptii}{false}
\newboolean{@myopt@oneside}
\setboolean{@myopt@oneside}{true}
%
\DeclareOption{myopti}{\setboolean{@myopti}{true}}
\DeclareOption{myoptii}{\setboolean{@myoptii}{true}}

\DeclareOption{oneside}{\setboolean{@myopt@oneside}{true}}
\DeclareOption{twoside}{\setboolean{@myopt@oneside}{false}}
%
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{memoir}}
\ExecuteOptions{myopti}
\ProcessOptions*
\ifthenelse{\boolean{@myopt@oneside}}
    {\PassOptionsToClass{oneside}{memoir}}
    {\PassOptionsToClass{twoside}{memoir}}
\LoadClass[12pt,final]{memoir}

[Tex/LaTex] Changing the default options of a document class

You could declare a string option that accepts the font size and defaults to 11pt. However, this will come at the expense of the top class no longer being aware of what exactly it is doing. But that's a principal problem of upwards compatibility. E.g.

\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{atop}[16/07/2011]

\RequirePackage{kvoptions}
% Declare a string option `fntsize' that is unique to the derived
% class `atop'. It will accept anything assuming `11pt' if
% unspecified.
\DeclareStringOption[11pt]{fntsize}
% probably more options...
\ProcessKeyvalOptions{atop}\relax
\PassOptionsToClass{\atop@fntsize}{article}

% Assume that any unknown option will be understood by the base class:
\DeclareOption*{%
  \PassOptionsToClass{\CurrentOption}{article}%
}
\ProcessOptions\relax

% Now load the base class with the `fntsize' option and any unknown
% option:
\LoadClass{article}

If you happen to be the author of the base class and hence have the freedom to make it "a good base class", you might do some fancier things. For example, you could add a macro that allows executing options after the class has been loaded. (Like hyperref's \hypersetup or geometry's \geometry.) Then you could further add a macro, say \getOptionList, that returns a comma separated list of all options. You may then retrieve the list of options accepted by the base class in the derived class and use it to make further decisions without hardcoding the status quo of base options.
