El siguiente es un ejemplo de cómo condensada para extraer los datos que entra en un *Org Agenda*
tampón cuando normalmente utilizando la función org-agenda-list
, con org-agenda-entry-types
tal como :deadline
, :scheduled
, :timestamp
, sexp
, :deadline*
, y :scheduled*
. El rango de fechas - begin
y end
- debe estar en un formato de lista gregoriano - por ejemplo, '(6 1 2015)
. Las opciones personalizables de let-bound son org-agenda-prefix-format
y org-agenda-entry-types
. La función devuelve un resultado en el formato de una lista.
