Serialize data in zserio format

EnzoXenon has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks ...

I have serialized data files in a format from zserio -> https://zserio.org/

I've read through the documentation for File::Serialize but there's no specific zserio serializer.

Is there a perl module which can read/write zserio blobs?

Humble thanks

If I understand your question, you only need Perl to decode file you already have? And as far as I can tell from some quick scanning of the docco, zsero "files" include some (compiled?) metadata about the structure, and a bit stream of the actual data. After having a quick look over the wire format at https://zserio.org/doc/ZserioEncodingGuide.html It looks like most of the actual work can be done by pack/unpack and a few %hash lookups. If there is need I could probably whip up a PP reader 🤷‍♂️	[reply]

My quick googling didn't show any. A quick read of the website shows it supports C++. To make a Perl module, you'd want to make an Alien package, see Alien::Build::Manual::AlienAuthor. Then make a separate Perl module that implements a Perl-idiomatic interface.	[reply]

Alright; I feel motivated. Do you have both the defs.zs and the data.zsb files? If you do, let me know and I'll go ahead and build a Pure Perl^* decoder. Looks like `Data::BitStream` can do the necessary reading. ^{* Well, my code will be PP. No promises about Data::BitStream}	[reply] [d/l]
