split-sequence separator-bag sequence &key start end test key coalesce-separators => sequences
A sequence.
A sequence.
Bounding index designators for sequence.
A function designator.
A function designator or nil.
The function split-sequence returns a list of subsequences of sequence (between start and end), split when an element in the sequence separator-bag is found. The structure of sequence is not changed and the elements matching separator-bag are not included in the resulting sequences.
The function test, which defaults to eql, is used to compare the elements of sequence and the elements of separator-bag.
If true, the function key, is applied to the elements of sequence before test is called.
If coalesce-separators is true, then empty sequences are removed.
