Thanks!

Quick question..

How do parse/input a list of ints (:uint-le) where the first contains the number of ints to read?

Do I need to read the first (:size) and then parse the rest with 'repeat' with parameter (as code) or is there a way to set this in the data specification?

Cheers, Paul

You could either use (repeated :uint-le :prefix :uint-le) for repeated elements with a length prefix, or the more generalized (header :uint-le (fn [len] (repeated :uint-le :length len)) count) which can be used for any kind of header/body encoding. For examples please refer to the tests, for example at https://github.com/smee/binary/blob/master/test/org/clojars/smee/binary/codectests.clj#L125 or https://github.com/smee/binary/blob/master/test/org/clojars/smee/binary/codectests.clj#L204
