I'm actually assured to hear the git CLI is better covered than libgit2 since the CLI test suite is what I used as my "validation" for progress on meeting git's functionality As fo…

Bun's attempted to integrate with libgit2 instead of spawning calls to the git CLI and found it to be consistently 3x slower iirc The micro-benchmarks are for the internal git oper…

If this were 2+ years ago perhaps, with industry adopting more agents in their SDLCs (ie Stripe minions or Ramp background agents), I think we're more a matter of time before we tr…

> Sure, if you have a complete test suite for a library or CLI tool, it is possible to prompt Claude Opus 4.6 such that it creates a 100% passing, "more performant", drop-in replac…

This was orchestrated and developed by agents with verifications like the codebase compiling or git's CLI test suite passing. That was so the commit authors don't all appear like b…

The original target was bun since it itself is written in zig, not because of anything specific to the language When it was clear that there were benefits in filling in more of git…

The reason being bun actually tested both using the git CLI as well as libgit2. Across the board the C library was 3x slower than just spawning calls to the git CLI. Under the hood…

I cross-posted to my personal blog too https://yev.bar/ziggit

Edge cases certainly apply with scripts depending on specific git CLI args or stdout strings may not suffice with ziggit. _However_, for the use cases that most developers or agent…

I ran the test suite specifically for git's CLI as that was the target I wanted to build towards (Anthropic's C compiler failed to make an operating system since that was never in …

> maintain a separate git implementation If git were a rapidly evolving project then I'd think this'd be a stronger issue. With git being more of an established protocol that proje…
