I would like to know if there's a way to use a command (including custom commands created with \newcommand) as parameter/option values). I would like to do something like this

\usepackage[someoption=\somecommand]{somepackage}
\usepackage[supporters={First line\\ Second Line}]{someotherpackage}

  • Not unless you are altering the package itself and adding your options. – Mica Jan 06 '10 at 00:23
  • Also note that package options are fully expanded, which makes them sort of impossible to use for anything like this. (Not so with keyval options, though.) – Will Robertson Jan 06 '10 at 02:58

  • The original question has been edited into an entirely different one. This is not allowed! The editor should ask their own question. The initial question was about passing option values via \documentclass, not via \usepackage. – Ahmed Musa Nov 26 '12 at 11:44

If you load the xkvltxp (or kvoptions-patch or catoptions) package before \documentclass, you will be fine: you can pass commands as values of options. To load a package before \documentclass, you should of course use \RequirePackage instead of \usepackage.

Two options

  1. You can check to see if a csname is defined using \ifdef in the package, so that defining \csname as a macro before invoking \usepackage can be checked. This isn't exactly what you asked, but it should, I guess, do what you want;
  2. You can pass the name of a command as a string without the backslash (say, to \input) in the options, and then bind the command using \edef\inputcs{\def\passname#1{\csname#1\endcsname}\expandafter\passname\input}.
