lazy dependency ergonomic enhancements #36009

Merged
andrewrk merged 9 commits from lazy-dependency-ergo into master 2026年07月02日 05:02:51 +02:00
  • fix maker crash when lazy dependencies are fetched
  • log when lazy dependencies are fetched
  • std.Build.dependency: support lazy dependencies
  • introduce std.Build.dependencyLazy which possibly returns error.LazyDependencyNeeded instead of null, so that you can use try
  • when user build functions return error.LazyDependencyNeeded, build system proceeds to fetch them rather than failing configuration
* fix maker crash when lazy dependencies are fetched * log when lazy dependencies are fetched * `std.Build.dependency`: support lazy dependencies * introduce `std.Build.dependencyLazy` which possibly returns `error.LazyDependencyNeeded` instead of `null`, so that you can use `try` * when user `build` functions return `error.LazyDependencyNeeded`, build system proceeds to fetch them rather than failing configuration
when running user build functions. This makes control flow a lot easier
to manage for lazy dependencies.
in favor of dependencyLazy which has a different function signature and
will be eventually renamed to dependency
migrating to all dependencies being potentially lazy by setting the flag
in build.zig.zon and embracing error.LazyDependencyNeeded propagation as
the way to deal with discovered needed dependencies.
solves the problem that handling the `null` case from `lazyDependency`
was annoying.
Now it supports lazy dependencies and if it needs to be fetched then it
will serialize the configuration and early-exit.
Maker: fix double use of Cache.hit() inside loop
