Arguments

documentation: A string.
sort-time: One of:execute or:define-action.
dummy-actions: A list.
default-order: A list.
execution-function: A function.

Description

Return an action-list not registered in the global registry of lists. The keyword arguments are as for define-action-list.

The documentation string allows you to provide documentation for the action list.

sort-time is a keyword specifying when added actions are sorted for the given list -- either:execute or:define-action (see *default-action-list-sort-time*).

dummy-actions is a list of action-names that specify placeholding actions; they cannot be executed and are constrained to the order specified in this list, for example

'(:beginning :middle :end)

: default-order specifies default ordering constraints for subsequently defined action-items where no explicit ordering constraints are specified. An example is

'(:after beginning :before :end)

: execution-function specifies a user-defined function accepting arguments of the form:

(the-action-list other-args-list &rest keyword-value-pairs)

: where the two required arguments are the action-list and a list of additional arguments passed toexecute-actions, respectively. The remaining arguments are any number of keyword-value pairs that may be specified in the call toexecute-actions. If no execution function is specified, then the default execution function will be used to execute the action-list.
