Hey Tzach, If I understand what you're trying to do, you want something like this:
[ :uint32 :ubyte ;; or bit-seq, depending (delimited-block (prefix uint24 #(- % 5) #(+ % 5))) ] And then you'll need to parse the final block separately. I've left defining the uint24 as an exercise for the reader (sorry, long day), but using (compile-frame [:uint16 :uint8] ...) should be pretty straightforward. Hope that helps, happy to answer any followup questions.
