using command in package options

Question

Hi, I would like to know if there's a way to use a command (something I create with \newcommand) in a package configuration). Something like \usepackage[someoption=\somecommand]{somepackage} Thanks for your help!

Answer 1

Not unless you are altering the package itself and adding your options.

Answer 2

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}.
