Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// ffi-objc-arc-01 — M4.A smoke test for NSObject + autoreleasepool.
|
|
//
|
|
// Exercises:
|
|
// 1. NSObject is declared in std/objc.sx and reachable from user code.
|
|
// `obj.retain()` / `obj.release()` dispatch via the M2.3 #extends-aware
|
|
// method chain. Pattern: `defer obj.release();` as the canonical
|
|
// sx idiom for owned Obj-C handles.
|
|
// 2. `autoreleasepool(body)` stdlib helper wraps `body` in a
|
|
// push/defer-pop pair so Foundation factory returns drain at block
|
|
// end.
|
|
//
|
|
// macOS-only — libobjc + NSObject must be available at runtime.
|
|
|
|
#import "modules/std.sx";
|
|
#import "modules/ffi/objc.sx";

#import "modules/build.sx";

main :: () -> i32 {

|
inline if OS == .macos {
|
|
// Manual retain/release on an NSObject instance — the
|
|
// `defer obj.release();` pattern is the canonical sx idiom.
|
|
obj := NSObject.alloc().init();
|
|
if obj == null { print("FAIL: alloc null\n"); return 1; }
|
|
defer obj.release();

|
// Bump the count and drop the extra; refcount math stays balanced.
|
|
_ = obj.retain();
|
|
obj.release();
|
|
|
|
print("retain/release: ok\n");
|
|
|
|
// autoreleasepool helper round-trip — just exercise that the
|
|
// push/pop pair executes. We don't have a side-effect to observe
|
|
// (NSObject.new returns a +1 retained, NOT autoreleased), so this
|
|
// is a smoke test of the helper's shape, not the runtime
|
|
// behavior.
