Hey all, just wanted to share the result of the work I've done recently here in the hope it helps people. Zippy <https://github.com/guzba/zippy>/ is new and pure Nim implementation of the deflate compression algorithm and the gzip and zlib data formats.
I hope this will save people a bunch of trouble fighting with wrappers for zlib, etc which I fought with myself (I work a lot Windows which makes this extra bad). There are a couple simple examples for using Zippy to handle gzip for HTTP client and HTTP server scenarios in the /examples dir of the repo. This is a fresh implementation so while I have a lot of tests in place and have fuzzed the library it is obviously not as mature as zlib. I'll be continuing to work on it from here.
