map-indexed
Macro
(map-indexed result-type fn &rest seqs)
Map fn over seqs with incrementing zero-based idx. The idx will get supplied as first arg to fn. result-type serves the same purpose as in #'map.
Arguments
result-type |
Result type to return. If nil, don't return a result. |
fn |
Function to map over sequences. Needs to accept (+ 1 (length seqs)) arguments. |
seqs |
One or more sequences where mapping gets applied, similar to map. |
Example
(map-indexed 'list #'list '(a b c d e) '(20 10 30 50 40)) ;; => ((0 a 20) (1 b 10) (2 c 30) (3 d 50) (4 e 40))
