Because of the braces in \GeomOpts its expansion fails when inserted as parameter to \geometry. I did read [1] and [2] but I didn't find a way to adapt this to my simpler \geometry case.

I did try with \expandafter before \geometry and before its braces. Also I did try with xparse's commands intented to define macros/command without success.

[1] Keyval Error with \includegraphics: options undefined

[2] Strip one level of braces for using keyval-value within nested keyval

    You can use the standard trick: \begingroup\edef\x{\endgroup\noexpand\geometry{\GeomOpts}}\x – Marco Daniel Dec 10 '13 at 19:40
  • Worked! Thanks. Can't be written without defining a new command \x? Why \begingroup and \endgroup in these places? – Emilio Lazo Dec 10 '13 at 20:49
  • The encapsulation is needed to define \x local and to use the power \edef. – Marco Daniel Dec 10 '13 at 20:53

You don't need this type of tricks. Options passed to the \geometry command are cumulative. So you can simply say


(which I think is your standard) and then add whatever adjustment you like in another \geometry command.

So, saying


is just the same as doing


which I think was your aim. I don't see how


is clearer than my suggestion above.

  • I don't know what happened. I wrote my post because I thought I had tried with exactly this syntax, that was my first guess after keyval error. Now it worked; I don't know what happened before. :-) Thanks egreg and Marco Daniel! – Emilio Lazo Dec 11 '13 at 17:56
