The execute-actions
macro executes, in sequence, the actions on the specified list. If the action-list specified by name-or-list does not exist, then this is handled according to the value of *handle-missing-action-list*. Note that name-or-list is evaluated.
If a user-defined execution function was specified when the action list was defined, then it should accept the following arguments:
( action-list other-args &rest keyword-value-pairs )
Note that other-args is passed as a single list.
If a user-defined execution function was not specified when the action list was defined, then the following default mapping occurs. Each action's data is invoked via apply on other-args:
( apply data other-args )
This behavior is modified by the keyword-value-pairs, thus:
If the keyword parameter :ignore-errors-p
is non- nil
, any otherwise-unhandled errors signalled inside the execution of that function will be trapped, and a warning issued. Execution continues with the next action-item. If :ignore-errors-p
is nil
(or not specified), then the error is not trapped.
If the keyword parameter :post-process
is non- nil
, the first value returned by each action is handled, according to :post-process
, thus:
collect values into list
return t
only if all values are t
. Return nil
immediately if any value is nil
return first non- nil
value
