I want a better build executor (jyn.dev)

In the latest installment of a series on build systems, the author introduces a new build executor called Ronin, which aims to enhance the build process by integrating advanced querying capabilities and runtime tracing. Ronin is designed to read an improved action graph serialization format and seamlessly slot underneath existing build systems like CMake and Meson. It emphasizes a gradual transition to hermetic builds—where builds are isolated from the host system—allowing developers to implement changes without overhauling their entire build configurations at once. Significantly, Ronin seeks to combine the strengths of existing executors, such as Bazel and Ninja, by offering a sophisticated query language reminiscent of Bazel's extensive capabilities alongside the simplicity of Ninja's command filtering. Additionally, Ronin will incorporate a tracing system that monitors file access and helps identify missing dependencies over time. This innovative design not only aims to make the build process more efficient but also to empower developers to refine their build environments actively, enhancing productivity and reliability within the AI/ML community and beyond.
