How to use :property properly?

[alphapapa]

Hi,

Please see the documentation of the property selector:

Group items with a property, optionally matching a value. Argument may be a property name string, or a list of property name string and either value string or predicate with which to test the value.

You're getting that error because it is indeed invalid.

If you want to insert the current week into the org-super-agenda-groups list, you'll need to use backquoting and unquoting, keeping in mind that the unquoting will only happen when you set the variable's value, not when the variable's value is accessed.

Backquoting, unquoting, and splicing is covered in a section of the Elisp manual. Simply, note the difference between what these forms evaluate to:

`(foo ,(format-time-string "%U"))
'(foo (format-time-string "%U"))

Thanks for your reply. In ielm I can see the difference between the both. When I then try to set:

  (:name "This Week"
    :property `("week" ,(format-time-string "%U"))
  )

then I get:

Wront type argument: sequencep, \`

Again: I want to match items with a property called week where the value is the current week number (aka format-time-string "%U")
