Summary of Changes

Hello @ensi321, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces zbuild as the new build system for the project. The change involves replacing the existing manual build.zig and build.zig.zon files with versions that are automatically generated by zbuild. A new zbuild.zon file is added to serve as the declarative configuration for all build artifacts, including executables, libraries, and tests. This adoption aims to streamline the build process and centralize build definitions.

Highlights

  • Migration to zbuild: The project's build system has been migrated to use zbuild, a new build tool for Zig projects.
  • Automated Build Script Generation: The build.zig file is now automatically generated by zbuild based on the new zbuild.zon configuration, replacing the previous manually maintained script.
  • New zbuild.zon Configuration File: A new zbuild.zon file has been introduced to centralize the definition of executables, libraries, and tests, serving as the primary configuration for the zbuild system.

Code Review

This pull request migrates the project's build system to use zbuild, which involves adding a zbuild.zon configuration file and auto-generating build.zig and build.zig.zon. The migration looks good overall, but I have a few suggestions for the configuration files to improve clarity, correctness, and adhere to best practices. My main points are to rename the executable for better description, remove redundant test definitions that cause tests to run twice, and restore an important security-related comment in the package manifest.

.options_modules = .{},
.modules = .{},
.executables = .{
.main = .{

The executable is currently named main, which is not very descriptive. The previous build.zig script named the executable state-transition, which seems more appropriate given the project's name. Consider renaming main to state_transition for clarity.

        .state_transition = .{

There is a naming conflict between this and .libraries.state-transition because zbuild will define module for each executable and library. So having state-transition in executables and libraries will generate a build.zig with naming conflict

lgtm as far as a port of what's already there.

I suppose most of the work is on other branches, but immediate things I see:

  • ssz-z isn't a dependency?
  • why is there an executable?
  • the state transition should be exported as a module, not a library
  • any bun-ffi binding library should consume the state transition module
