Returns a list of subsequences of a sequence, split at elements for which a predicate returns true.
A function designator.
A sequence.
Bounding index designators for sequence .
A function designator or
nil
.
The function
split-sequence-if
returns a list of subsequences of
sequence
(between start and end), split by where the function
predicate
returns true for an element. The structure of
sequence
is not changed and the elements identified by the predicate are not included in the resulting sequences.
If non-nil, the function key is applied to the elements of sequence before predicate is called.
If coalesce-separators is true, then empty sequences are omitted from result .
