0.17 drops `**`, findProgram's two-slice form, b.install_prefix and b.build_root, std.builtin.Type.UnionField, and @typeinfo's decls list, which is now decl_names. The rest is zig fmt's own upgrade to @backingInt and @fromBackingInt. @hasDecl now sees only pub decls, even from the same file, so the "Stream decls" tests returned before checking anything: S is private. Every type that runs them has S, so the guard is gone. The prefix in libxev.pc is no longer known when build.zig runs; it is relative to the .pc file instead. build.zig declares the directories it lists, so a new example, benchmark or man page reruns it.

Most of CI builds inside the flake, so it takes 0.17.0 from a zig-overlay revision that has it. libxev.pc now finds its prefix relative to itself, and nix moves it into the dev output, apart from the libraries in $out; the package sets the prefix back to $out. Assisted-by: Claude Opus 5.5

Closes #248.
Builds and tests on Zig 0.17.0, which this makes the minimum.
**is gone: test arrays use@splat.b.findProgramtakes.{ .names = ... }and returns an optional.b.install_prefixisn't known when build.zig runs any more, solibxev.pcsetsprefix=${pcfiledir}/../.., relative to where it isinstalled. The nix package moves the
.pcinto itsdevoutput, away fromthe libraries, so
nix/package.nixsets the prefix back to$out.b.build_rootisb.root, a path. build.zig declares the directories itlists (
src/bench,examples,docs) withdependOnDirectoryContents,so adding a file to one reruns it under 0.17's configure cache.
@typeInfo(...).@"struct".declsisdecl_names;std.builtin.Type.UnionField.Attributesisstd.lang.Type.Union.FieldAttributes.zig fmtupgraded@intFromEnum/@enumFromIntto@backingInt/@fromBackingInt.One behaviour change to know about:
@hasDeclnow sees onlypubdecls,even from the same file. The "Stream decls" tests began with
if (!@hasDecl(Impl, "S")) return;, andSis private, so on 0.17 theyreturned before checking anything. Every type that runs them has
S, so theguard is gone and they check again.
The flake takes 0.17.0 from the zig-overlay (
nix flake update zig, todcffc7a); nothing else in the lock moved.
Tested:
zig build teston macOS (59 pass) and on Linux aarch64 with epolland io_uring (143 pass, 3 skipped), the examples and benchmarks, and a build
for each CI target (aarch64/x86_64 Linux gnu and musl, aarch64/x86_64 macOS,
x86_64 Windows). The same counts as main on 0.16. In a
nixos/nixcontainer (aarch64-linux):
nix flake check, the dev shell'szig buildforevery CI target, its tests (143 pass, 3 skipped), examples and benchmarks,
and
nix build, whoselibxev.pcresolves to thedevoutput's headers and$out's libraries.🤖 Generated with Claude Code
