Non userei affatto la sintassi di xifthen per quel tipo di impostazioni (non userei \ifthenelse nemmeno sotto minaccia fisica, per la verità :)). Forse sarebbe più semplice dire
`\DeclareOption{red}{\def\mirko@color{red}\chardef\mirko@colnumber\z@}
\DeclareOption{green}{\def\mirko@color{green}\chardef\mirko@colnumber\@ne}
\DeclareOption{blue}{\def\mirko@color{blue}\chardef\mirko@colnumber\tw@}`
Per il codice successivo puoi usare \mirko@color quando hai bisogno del nome del colore; per codice diverso a seconda dei colori puoi usare \ifcase:
`\ifcase\mirko@colnumber
\or
\or
\fi`
Molto più facile da mantenere, secondo me, e anche da estendere.

Ciao Enrico,
Grazie dei consigli, che han fatto funzionare il codice, almeno parzialmente.
Nel senso che usando dei flag, il codice va effettivamente all’interno dei casi previsti, ma i comandi non vengono eseguiti… Riporto quello che si trova subito dopo lo stralcio di codice dei messaggi precedenti`\usetheme{Warsaw}
\beamertemplatenumberedballsectiontoc
\ifcase\mirko@colnumber
{ %Rosso
\usecolortheme[rgb={.5,0,0}]{structure}
}\or
{ %Verde
\usecolortheme[rgb={0,.5,0}]{structure}
}\or
{ %Blu
\usecolortheme[rgb={0,0,.5}]{structure}
}\fi`Questo equivale a non dare nulla (che per la struttura del tema, è come dare il blu)… strano comportamento!
Per flag, ho tolto i commenti a Rosso, Verde, Blu e ho visto che effettivamente scopre solo l’errore nella posizione giusta e lo scrive nel pdf.

Il codice dentro i case, se portato fuori, funziona correttamente e fa il suo lavoro!

Come mai?

Grazie e buona serata,

Perché quelle graffe? Specificando il rosso sarebbe come scrivere
`\usetheme{Warsaw}
\beamertemplatenumberedballsectiontoc
{\usecolortheme[rgb={.5,0,0}]{structure}}`
che non è certo corretto.

Ciao
Enrico

Me culpa…

Grazie!!

Ciao a tutti,

Quindi non riesce a gestire l’opzione per isodate e soprattutto non riesce a cambiare il colore…

Qualcuno sa aiutarmi?

Grazie a tutti,

P.s. Non è che magicamente ora non funziona; non ricordo di averlo modificato dopo l’ultimo messaggio in discussione, ma ora di fatto non va…

Ciao a tutti,
Risollevo questo topic che avevo creato tempo fa e che avevo lasciato in quanto tutto funzionava.

Perché \RequirePackageWithOptions{isodate}? Togli WithOptions: stai chiedendo a isodate di valutare esplicitamente le opzioni globali e non sa che farsene. Già che ci sei togli anche la chiamata di graphicx che è già fatta da beamer. Toglierei anche WithOptions dalla chiamata di beamer.

Ciao
Enrico

Ok, tolto graphicx…
Quanto ad isodate, facevo così in modo che “leggesse” la lingua che passo come opzione globale a tutti i pacchetti. Non è corretto?
Togliendo il withoptions alla chiamata di beamer, tutto è tornato a funzionare.

Altra domandina:
Ora, se io passo l’opzione handout per fare le trasparenze in versione stampa, non funziona… questo è un po’ scomodo…
