A detailed blog post about building a C compiler from scratch using the Zig programming language. The author explores compiler design principles, parsing, code generation, and how Zig's unique features like comptime and explicit memory management make it a compelling choice for systems programming tasks like compiler development.
Zig's strict anti-LLM contribution policy (banning LLM use for issues, PRs, and comments) is rooted in valuing long-term human contributors over code. Loris Cro explains that reviewing LLM-written PRs does not help grow new trusted project members. As a consequence, Bun—a major Zig-based project—will not upstream performance improvements due to this ban.
Zed is a font superfamily designed for reader needs, tested with visually impaired patients where it outperformed Helvetica in reading speed. It includes Text and Display optical versions, supports 547 languages, and offers variable axes for width, weight, roundness, and slant.
Zig creator Andrew Kelley argues that it's a misconception people can't tell who is using LLMs, claiming LLM hallucinations differ fundamentally from human mistakes and that frequent agentic-coded contributors have a noticeable "digital smell." He compares it to smokers entering a room and states his project will not accept LLM-assisted contributions.
Zed is a type system designed for optimal readability, tested with visually impaired patients where it outperformed Helvetica in reading speed. It comes in Text and Display optical versions with four variable axes and supports 547 languages.
Zig's build system is becoming faster with improvements to the compiler and build runner. Recent changes have reduced build times by optimizing dependency tracking and parallel execution. These enhancements make development workflows more efficient for Zig programmers.
