const S = struct {
    fn foo() void {}
};
comptime {
    const foo = S.foo;
    foo();
}

On the positive side, the new protocol lays the foundation for future improvements in ZLS and related tooling. Especially editors could utilize it to integrate unit testing, fuzzing, code coverage reports or debugging capabilities that are fully aware of the Zig build system.

All known regressions are tracked in #3277 and listed below:

Package @imports in build.zig

Type resolution for package imports in build.zig files have regressed.

Upstream Zig Issue: ziglang/zig#36387

Module @imports to exported modules without a compile step

Type resolution for modules that are only exported using b.addModule but aren’t tied to a compile step have regressed.

An build.zig file that would be affected:

const std = @import("std");
pub fn build(b: *std.Build) void {
    _ = b.addModule("foo", .{
        .root_source_file = b.path("root.zig"),
        .imports = &.{
            .{ .name = "bar", .module = b.createModule(.{ .root_source_file = b.path("bar.zig") }) },
        },
    });
}

In the above example, @import("bar") will not be resolved.

Upstream Zig Issue: ziglang/zig#36388

Build system protocol file watching doesn’t work on windows

File watching has regressed on windows due to a bug in the build system protocol. This does not affect the CLI when running zig build --watch.

ZLS does work around this issue by receiving file save events through the LSP protocol. File changes through external programs (e.g. version control) will not be detected.

Upstream Zig Issue: ziglang/zig#37236
