Show HN: Stb_zip – header-only C ZIP parser, zero dependencies, fast

4 points by Forgret 1y ago

I've built a small, header-only C library to parse ZIP archives with no external dependencies. It works on everything from embedded devices to desktop games and supports both "store" and "deflate" compression. Benchmarks (Core i7-12700K, 32GB RAM): - Decompress 1GB: 0.8s (2.1x faster than miniz) - Parse 100k files: 12ms (3.2x faster) - CRC32 of 1GB: 0.2s (5.5x faster) GitHub: https://github.com/Ferki-git-creator/stb-zip https://github.com/Ferki-git-creator/stb-zip MIT licensed, feedback welcome.

What is the significance of a library being "header-only"? C headers can include arbitrary code, right? So why is "header-only" better than having file.h & file.c?

  Why would I want to deal with downloading and handling multiple files when I can just use a single file? Turning a header-only library into file.h and file.c is easy if I want to do it. Turning a multi-file project into a single header file is a lot more work.

    A "header-only" library can presumably be multiple header files, which is not what you are discussing. Why not say what you really mean? Which seems to be: "single-file" library.

I tried it out to see if I would want to use this instead of miniz which I am using at the moment, but the example seems to be missing some includes. I filed an issue with the details: https://github.com/Ferki-git-creator/stb-zip/issues/1 https://github.com/Ferki-git-creator/stb-zip/issues/1 Edit to add: I see now that you also did the Uprintf submission from a few days ago (https://news.ycombinator.com/item?id=44960664 https://news.ycombinator.com/item?id=44960664) which had some baffling bugs, and then you mentioned that you were using AI for some of it. That might explain the missing parts here too.

  This is possible not only fault with AI, because I always do tests, but sometimes I don't always manage to cover all platforms like this Linux, because I have to admit that I don't have a PC, and I did all this on my phone.
