Sweep all src/**.zig comments that cite resolved issues (issue NNNN /
fix-NNNN / KB-N): the invariant or mechanism each comment states is
kept; the historical citation is dropped, per the no-conclusion-comments
rule. Pure-history parentheticals are removed outright. References to
the 16 still-open issues (0030, 0041-0056) are untouched, as are test
NAMES carrying regression provenance (matching the sanctioned
"Regression (issue NNNN)" example-header convention).
Also removes the issues/0019-import-non-transitive-c-scope/ fixture dir
— the issue is superseded and its behavior is covered by
examples/0706-modules-import-non-transitive.sx (the .md writeup stays).
issues/0030's repro .sx stays: that issue is an open feature request.
Gate: zig build OK; zig build test 426/426; run_examples 541/0; zero
expected/ snapshot churn.
A bare reserved-type-name `::` declaration was silently accepted, and the
attempt-2 lowerCall rewrite then made a bare `s2 :: (…) {…}` function callable —
bypassing the backtick rule for handwritten sx. The reserved-name binding check
covered `:=` / typed-local / param / captures but NOT the `::` declaration form.
- ast: `ConstDecl`/`FnDecl` carry `is_raw` + `name_span` threaded from the parser
(parseConstBinding / parseFnDecl, all call sites incl. struct/impl methods).
- semantic_diagnostics: reject a bare reserved spelling at EVERY declaration-name
site — const, function (incl. struct/impl methods), struct/enum/union/error-set,
protocol, foreign-class, ufcs alias, namespaced/library/c-import name. Backtick
(`is_raw`) and the compiler's `#builtin` definition (`string :: []u8 #builtin`)
are the only exemptions; a value whose node is itself a named decl defers to
that node's own check.
- c_import: synthesized foreign fn_decls are `is_raw = true`, so a C function
whose own name collides with a reserved spelling (`int s2(int);`) imports and
bare-calls unedited.
- lower: scope the `.type_expr`→`.identifier` call rewrite to a callee FnDecl of
RAW provenance (`is_raw`) — only a backtick / `#import c` foreign fn can carry a
reserved-name spelling, so a non-raw match never gets rewritten.
- examples: 0153 (positive — backtick `::` const + fn, bare + tick call), 1140
(negative — bare `::` const + fn rejected).
- docs: specs.md + readme.md state the backtick is required at every binding site
including `::` const / function / type declarations; issue 0089 banner updated.
Reserved type-name spellings (s1, s2, u8, …) can now be used as value
identifiers two ways, resolving issue 0089:
1. Backtick raw identifier: a leading backtick (`s2) lexes to an
.identifier token carrying a new Token.is_raw flag, with the backtick
excluded from the text. A raw identifier is never type-classified — the
parser skips Type.fromName for it — so it is always a value identifier.
The flag threads to VarDecl.is_raw / Param.is_raw at binding sites, and
the reserved-type-name check (UnknownTypeChecker) skips raw bindings.
Because the token tag stays .identifier, the escape works in every
position (local, global, param, field, fn name, struct member, later
reference) with no per-site parser change.
2. #import c exemption: c_import.zig synthesizes foreign decls with
Param.is_raw = true, so generated C param names that collide with
reserved type names (s1, s2) import unedited.
A bare reserved-name binding in sx still errors (issue 0076 preserved):
the is_raw-gated skip only fires for backtick / foreign names, and a raw
binding's address-of / autoref lowering stays correct because every
occurrence is an .identifier, never a .type_expr.
Tests: examples/0151 (backtick, every position),
examples/1220 (foreign exemption, compiled+run), lexer unit tests.
1119 (bare-binding rejection) stays green. specs.md + readme.md updated.
C imports (stb_image, stb_truetype) compiled via the embedded LLVM
clang library now resolve bionic headers on Android. main.zig auto-
fills target_config.sysroot with the NDK root (mirroring the iOS path
that auto-fills the iOS SDK path); c_import.zig derives the bionic
sysroot inside it and passes `--sysroot <ndk>/toolchains/llvm/prebuilt/<host>/sysroot`
to the embedded clang.
Android link branch in target.zig stops auto-appending entries from the
collected `#library` / `#framework` lists. Most `#library` directives
in the stdlib (`objc.sx`'s `objc :: #library "objc";`, frameworks set
by uikit.sx, etc.) describe Apple-specific intent that's nonsensical on
Android. Users opt into Android-side libs via `opts.add_link_flag(...)`
in build.sx — same shape as how the iOS branch already lists frameworks
in chess's configure_build.
Verified end-to-end: chess game compiles for Android, packages into a
debug-signed APK, installs and launches on Pixel 7 Pro. It crashes in
UIRenderer.init because raw GL calls run before EGL is up — same
architectural gap iOS bridges via the Metal GPU protocol. Next step
is a GLES3 GPU impl or a lazy-init in UIRenderer. 86/86 regression
tests + iOS-sim chess build clean.
- `-F <dir>` CLI flag adds Apple framework search paths (parallel to `-L`).
- `TargetConfig.framework_paths` flows into the iOS link line (`-F<dir>`).
- iOS link adds `-Wl,-rpath,@executable_path/Frameworks` so embedded
frameworks resolve at runtime.
- `createBundle` now takes the framework list; for each one it locates
`<name>.framework` in the `-F` paths and `cp -R`s it into
`<bundle>.app/Frameworks/`.
- `c_import.compileCToObjects` forwards `-target`/`-isysroot` to clang so
`#c_import` works under cross-compile (was using host clang implicitly).
- iOS SDK is auto-discovered once at startup and shared by both the C
compile and the link paths.
- `SX_DEBUG_LINK=1` prints the resolved link argv.
- `library/modules/sdl3.sx`: drop `#library "SDL3"` — linking is now
per-target (build.sx handles `-lSDL3` on macOS, `-framework SDL3` on iOS).
