Delete C, deploy drama
Zig Libc
Zig tosses old C code; fans cheer while skeptics shout “security!”
TLDR: Zig is replacing chunks of the basic system toolkit (libc) with its own Zig code, promising speed and smaller apps. Commenters are split between AI-fueled “finish it fast” optimism and tough security questions, with extra hype about future I/O controls—and memes sparked by “Abolish ICE.”
Zig just started a very public breakup with its old C baggage: 250 C files are gone, replaced by Zig-made wrappers for everyday functions like copying bytes and basic math. The promise? Faster builds, smaller installs, and leaner apps. Thanks to Zig’s integrated tools, the new libc now shares the same compilation unit with other Zig code, letting everything optimize together—think “turbo mode” done early, not slapped on at the end. And the teaser everyone’s drooling over: future switches that could reroute all input/output through fancy event loops (hello io_uring), or even turn on resource leak detection for outside C code.
Cue the comments: the AI crowd says this is “mechanically translatable” and wants to unleash LLMs and agents to finish the port in days. The BSD crew waves in, asking if kqueue gets love too. Security hawks crash the party with hard questions: if Zig rewrites libc pieces, who tracks new vulnerabilities (CVEs) from glibc and musl and decides what applies? Meme patrol seized the sign-off “Abolish ICE,” turning the thread into a Bad Bunny fan club. Practical voices remind: file bugs with Zig first, not musl/mingw/wasi. Meanwhile, calls of “Delete 2032 more!” and shout-outs to libc-test keep the vibe half hype, half reality check.
Key Points
- •Zig is replacing vendored C libc sources with Zig standard library wrappers, removing about 250 C files with 2032 remaining.
- •Integrating zig libc into the same Zig Compilation Unit as other Zig code enables cross-optimization and removes redundant code.
- •The transition improves compilation speed, reduces Zig’s installation size, and lowers binary sizes for statically linked applications.
- •Potential (not yet tested) exists to globally control libc I/O behavior via std.Io, e.g., routing read/write through io_uring or enabling leak detection.
- •Users should report issues with Zig-provided musl, mingw-w64, or wasi-libc to the Zig project first to avoid misdirected bug reports.
