I'm writting a package in which the user may choose between three types of documents through declared options when issuing the usepackage command: undergraduatethesis, technicalreport and academicpaper. For this I'm using xkeyval so people use the command like usepackage[documenttype=academicpaper]{mypackage}.

I'm organizing the package in different sections, each with a type of configuration (spacing, figure configuration, titles, etc.) and I would like to put my document-type-specific commands in these separate sections, for example:

if{documenttype}{undergraduatethesis}

    % do something

fi



if{documenttype}{academicpaper OR technicalreport}

    % do some other thing

fi

I've tried a couple things, but I failed. The method I tried were not exactly like my situation, though.

Is this possible?

Thanks!

Found an answer myself after realizing I made the mistake everyone warned me about: the placement of ProcessOptions, or, in my case ProcessOptionsX, since I'm using the xkeyval package.

I used the following bit if code to assign values to some variables in order to distinguish the three document types (for simplicity I'll call them A, B and C):

defA{A} % creates macro named A (not sure if this value matters)

defB{B} % creates macro named B

defC{C} % creates macro named C

I did that in order to later use the ifx command and compare two macros. Now, using the xkeyval package's syntax to create package options:

makeatletter

define@key{fam}{documenttype}{%

    ifthenelse{equal{#1}{A}}{% if user types: documenttype=A

    defdocumenttype{A}}{% assigns value "A" to documenttype macro

    relax % not sure if needed

    }



    ifthenelse{equal{#1}{B}}{% if user types: documenttype=B

    defdocumenttype{B}}{% assigns value "B" to documenttype macro

    relax % not sure if needed

    }



    ifthenelse{equal{#1}{C}}{% if user types: documenttype=C

    defdocumenttype{C}}{% assigns value "C" to documenttype macro

    relax % not sure if needed

    }

}

makeatother

ProcessOptionsX<fam>relax

Great, now the macro documenttype has a value defined by the user. Now, we can write codes that will be compiled only when the user has specified a certain value to documenttype, using ifx.

ifx documenttype A % check if documenttype is equal to A

% insert commands for when user chooses A

else % not sure if needed

relax % not sure if needed

fi



ifx documenttype B % check if documenttype is equal to B

% insert commands for when user chooses B

else % not sure if needed

relax % not sure if needed

fi



ifx documenttype C % check if documenttype is equal to C

% insert commands for when user chooses C

else % not sure if needed

relax % not sure if needed

fi



% exactly HERE is where I was placing ProcessOptionsX, shame on me!!

That's it! Now I can use any booleans!!
