Lex 'extern' and 'export' as keywords beside 'callconv': new token.Tag
variants + keywords StaticStringMap entries + LSP semantic-token keyword
classification. Adds a 'lex linkage keywords' unit test.
Tokens only — parser/AST plumbing and lowering land in later phases.
Corpus sweep confirmed no .sx identifier collides with the new reserved
words. lock commit per the cadence rule.
Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.
Each side of '..' takes an optional bound marker, defaulting to
start-inclusive, end-exclusive (a..b == a=..<b; a..=b stays the short
end-inclusive spelling):
for 0<..<N (i) { } // 1 .. N-1 (both exclusive)
for 0=..=N (i) { } // 0 .. N (both inclusive)
for 0<..=N (i) { } // 1 .. N
for 0..<N (i) { } // 0 .. N-1 (explicit default)
for xs, 2<.. (x, i) // open range, exclusive start: i = 3, 4, ...
The nine lexemes are single tokens (maximal munch on '<'/'='/'..'), so
expression parsing never sees the leading marker as a comparison; '<',
'<<', '<=', '==', '=>' lex unchanged. An explicit end marker makes the
end expression mandatory; open forms are a.. / a<.. / a=... Works in
runtime, multi-iterable, and inline-for headers.
Regression: examples/0051-basic-for-range-bounds.sx (full matrix, open
start-marked ranges, comptime unroll, runtime bounds, lexer
non-regression); 1152's pinned message generalized.
The for header is now a comma-separated list of iterables with a
positional capture group and no ':' separator:
for xs (x) { } // collection
for 0..n (i) { } // range (end exclusive)
for 1..=5 (a) { } // ..= inclusive end
for xs, 0.. (x, i) { } // index idiom (replaces (x, i))
for xs, ys (x, y) { } // parallel (zip) iteration
for xs (x) => sum += x; // arrow body (full statement)
First-iterable-wins: the first iterable's length drives the loop and
must be bounded; the other positions follow by their own cursors (a
non-first range's end is not consulted or evaluated; a shorter
non-first collection is read past its length on mismatch). The old
single-iterable index capture is replaced by the trailing open range.
Capture/call disambiguation is positional: the paren group immediately
before '{' or '=>' is the capture, every earlier top-level group is a
call. 'for zip(a, b) (x, y)' calls zip; 'for f(n) { }' reads (n) as
the capture and errors with a parenthesize/add-capture hint. The old
':' form errors with a migration hint.
Lowering is unified across forms: one cursor slot per position (ranges
start at their start, collections at 0), all advanced together, the
first position's bound terminating. inline for keeps the single
bounded comptime range.
Migrated the full corpus (examples, library modules, issue repros,
in-source test strings). New coverage: examples/0050 (the full feature
surface) and examples/1149-1155 (seven diagnostic faces). specs.md For
Loop section + grammar rewritten; readme teaser updated.
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.
Adds `src/lsp/corpus_sweep.test.zig`: a permanent test that drives the
editor analyzer (`DocumentStore.analyzeDocument` — the exact path the
server's `textDocument/didOpen` uses) over EVERY `.sx` file in the
example + issue corpora, in process. The contract: analysis must
complete without panic/abort for any file. A panic aborts the test
binary — the loud CI signal that some new AST node shape crashes the
analyzer (the bug class issue 0099 fixed at sema.zig:397).
- Corpus dirs are injected as absolute paths at configure time
(build.zig `corpus_paths` options module) so the sweep is
CWD-independent; the FILE LIST is still read from disk at test time,
so new examples are covered automatically with no test edit.
- Imports resolve against the shipped `library/` (root_path + stdlib
path set), so the analyzer runs over real, fully-resolved code —
maximum crash surface, mirroring an editor session opened on the repo.
- Wired into `zig build test` via the `src/root.zig` lsp barrel, same
mechanism document.test.zig uses (refAllDecls reaches one struct deep,
so the file is referenced directly).
- `SX_LSP_SWEEP_VERBOSE` prints each file before analysis; on a crash the
last printed line names the offending file.
Coverage: 470 examples + 1 issue repro analyze with zero crashes.
Regression-guard proven: temporarily reverting A's sema.zig:397 fix
(`@intCast(ate.length.data.int_literal.value)`) makes the sweep abort
with `access of union field 'int_literal' while field 'identifier' is
active`; restoring it turns the sweep green.
`Analyzer.resolveTypeNode` read the array `.length` node's `.int_literal`
union field unconditionally. For a named-const dimension (`MAX :: 4;
[MAX]u8`) that node is an `identifier`, so the access tripped Zig's
checked-union panic and `sx lsp` aborted on didOpen. The main compiler
was unaffected (it folds the dim through the IR).
- New `arrayDimLength` helper switches on the dimension node tag:
int_literal → value; identifier → a recorded module-const int value;
anything else / out-of-u32-range → unknown. Never assumes a node shape.
- `Type.ArrayTypeInfo.length` is now `?u32`; null is an explicit "editor
couldn't fold this dimension" marker (rendered `[_]T`), never a
fabricated concrete length.
- New `const_int_values` registry records integer-literal consts at
registration time for the identifier path.
Regression: first `src/lsp/*.test.zig` (the minimal LSP harness), wired
into the test graph via `src/root.zig`. Drives `analyzeDocument` over
`[MAX]u8` (folds to 4, no panic), `[64]u8` (happy-path guard), and
`[N]u8` (explicit unknown). Fail-before/pass-after verified.
Sibling audit of the resolveTypeNode/fieldType family: the array dim was
the only unchecked union-field access; all other arms recurse or
tag-check first. Noted a non-crashing display gap in server.zig hover
rendering for step B.
Remove the last compiler dependency on sema as semantic truth and stop
publishing as-you-type sema diagnostics from the LSP.
- core.zig: drop dead `Compilation.analyze()`, the `sema_result` field,
and the sema->diagnostics merge; drop the now-orphaned sema import.
The CLI pipeline (parse -> resolveImports -> generateCode) never called
analyze(), so this removes only dead code.
- lsp/server.zig: rename `analyzeAndPublish` -> `refreshEditorIndex` and
delete its sema-diagnostic publish (and the now-unused `semaToLspDiags`).
The editor index (doc.sema) is still refreshed for nav/refs/completion/
tokens. On-save/on-open diagnostics still come solely from the canonical
compiler pipeline in `runProjectCheck` (unchanged).
- Document sema as an editor-indexing API (doc.sema field comment).
Intended behavior change: as-you-type sema diagnostics no longer publish;
on-save canonical diagnostics are the sole source. CLI compile output and
the 361-example suite are unchanged (361/0, zero snapshot churn).
Finishes Phase E4. `process.exit` / `assert` now report the caller's location.
#caller_location + Source_Location:
- new `hash_caller_location` token (lexer) + a leaf `caller_location` AST node
(parser primary-expr; sema + lsp arms).
- `Source_Location :: struct { file; line; col; func }` in std.sx.
- expandCallDefaults rewrites a `#caller_location` param default to a marker
carrying the CALL site's span + source_file.
- lowerCallerLocation synthesizes the struct: file + line:col via
errors.SourceLoc.compute over the diagnostics file→source map, stamped with
the enclosing (caller) function name. inferExprType resolves it to
Source_Location. Explicitly forwarding a Source_Location through an inner
call preserves the outermost site.
namespaced default-param expansion (pre-existing crash): expandCallDefaults
bailed on field_access callees, so `mod.fn(args)` with an omitted defaulted
param passed too few args → LLVM "incorrect number of arguments". Now resolves
the namespace fd (by field / qualified name); method-on-value calls (where
`self` shifts the count) stay excluded. Prerequisite for process.exit/assert
(always called namespaced) taking `loc = #caller_location`.
comptime flush: interp.callForeign flushes the interpreter's buffered print
output before invoking any host symbol, so a comptime diagnostic emitted just
before a terminating `_exit` (process.exit at comptime) survives.
process.exit/assert take `loc: Source_Location = #caller_location`; assert
prints `ASSERTION FAILED at <file>:<line>: <msg>`. examples 250 (assert
file:line), 251 (caller-location + forwarding). The two ffi-objc *.ir
snapshots are regenerated — adding Source_Location to std.sx renumbers the
global string pool the type/field-name tables index (benign, identical IR).
Parser-only second step of the error-handling stream. No sema/codegen.
- token: 4 keywords — `raise`, `try`, `catch`, `onfail`.
- ast: RaiseStmt, TryExpr, CatchExpr {operand, binding?, body, is_match_body},
OnFailStmt {binding?, body}.
- parser:
- `try` is a unary prefix (binds tighter than `or`; right-recursive so it
stacks under `xx`/`@`/etc).
- `or` is already left-associative (precedence-climbing loop) — no change.
- `catch` is a postfix with four body shapes (no-binding block / block /
bare-expr / `== { case }` match-body, the latter reusing parseMatchBody
with the binding as subject).
- `raise EXPR;` and `onfail [e] { } | onfail EXPR;` statements; `error`
parses in expression position so `raise error.X` works; raise rejected
in expression position and inside an onfail body (in_onfail_body flag).
- consumer-aware `|>`: pipes the LHS into the head call through a
try/catch/or wrapper, preserving the wrapper.
- print: printExpr + match-arm printing for round-trips (anyerror!void to
break the printExpr<->printMatchArms inferred-error-set loop).
- sema/lsp: exhaustive switch arms for the 4 nodes + 4 keyword tokens.
- tests: ~22 inline parser tests (precedence, all catch forms, both
rejections, pipe cases, round-trip prints incl. match-body).
zig build, zig build test (264), and 254/254 examples green.
Reuse the compiler's lowering pass instead of re-implementing its checks
in sema. A module can't be lowered standalone — lowering only type-checks
functions reachable from a root — so the open file alone misses errors
like a *Move passed into a by-value method parameter. Drive the workspace
entry (main.sx) through parse → resolveImports → lowerToIR, then attribute
each diagnostic back to its file via source_file and publish per file
(clearing files whose errors are gone).
Runs on didOpen/didSave (disk-based); sema stays the live per-keystroke
layer. Advertise textDocumentSync.save so the editor sends didSave.
collectProjectDiagnostics is split out (transport-free) and covered by a
hermetic temp-project test.
Cmd+clicking a struct field / method / enum-variant at its own
declaration returned null, so nothing happened — while find-references on
the same token worked. Resolve a definition-site click to its own
location; the editor then surfaces references on a definition-click
instead of doing nothing. Member uses still resolve to their definition.
Add selfMemberDefAt + a regression test.
find-references only searched documents the editor had open, so asking
for references to a field from a file whose users were all closed
returned just the definition. Load every .sx under the workspace root
before matching so uses in unopened files are found too.
The LSP server's own tests were dormant: nested under the `lsp` struct in
root.zig, refAllDecls never reached them, and they had bit-rotted (stale
DocumentStore.init arity, an unaligned dummy io, fake /test/ paths that
no longer resolve). Reference the lsp files directly so their tests run,
give the doc-store tests a real Threaded io with bare paths, and fix the
stale extractIdentAtOffset expectation.
Extract referencesPayload from the transport so it is unit-testable, and
add tests covering cross-document field references, includeDeclaration,
the for-loop capture inlay hint, and workspace file loading.
The sema analyzer bound a for-loop capture with no type, so navigating
or hinting through it (m.flag, m: Move) failed. Instantiate generic
field types (legal_moves: List(Move)) and infer the capture's element
type from the iterable — List-like structs, slices, arrays, many-
pointers, and a pointer followed to its pointee. By-ref captures bind a
pointer to the element; range cursors bind s64.
Inlay hints now descend into struct method bodies and emit a type label
for the capture itself.
Members aren't symbols, so their uses were never recorded. Adds a member-reference list (declaration + uses) tracked during analysis: struct fields/methods and enum variants as declarations; field access, method calls, bare enum literals, qualified Type.variant, and match-arm patterns as uses. Spans are derived from the source-relative name slices; uses carry the owner type (via inferExprType, dereferencing pointers). find-references matches by (owner, name) across loaded documents, treating an unknown owner as a wildcard.
Verified: references for a field (legal_moves), a method (clear_valid_targets), and a variant (promote_rook — decl + comparisons + case patterns + struct-literal values across 5 files).
cmd-clicking a definition (or any use) now lists all references. Same-file matches are precise (by symbol index); cross-file matches a top-level name across loaded documents. Advertises referencesProvider. Verified: references to a free function resolve across files (rules.sx def + internal calls + main.sx caller).
resolveStructTypeName returned null unless the variable's type was exactly a struct, so 'board.castling' (board: *Board) couldn't locate the Board declaration. It now also returns the pointee struct name for a pointer-to-struct, read from the resolved symbol type. Verified: board.castling navigates to board.sx's castling field.
Feature 0 complete. addNote/addHelp bundle notes and help-blocks under a
primary diagnostic (handle from new addId/addFmtId); help blocks carry an
optional fix-it line that substitutes the suggested source. renderExtended
now renders primary -> notes -> helps with blank-line separators.
Wire the CLI to the extended renderer (renderErrors -> renderStderr) and
flip render_style default to .extended; the previous renderErrors ->
renderDebug path bypassed render() entirely, so flipping the field alone
was a no-op. 13 diagnostic snapshots re-rendered to the extended format.
Make-green half of the cadence step started in A1. Wires the
`#selector` directive end-to-end:
- Lexer token `hash_selector` at src/token.zig + lookup row in
src/lexer.zig.
- AST field `selector_override: ?[]const u8 = null` on
`ForeignMethodDecl` (src/ast.zig).
- Parser block in src/parser.zig that mirrors
`#jni_method_descriptor` — both occupy the same slot after the
optional `-> ReturnType` and before the body/terminator. Not
mutually exclusive at parse time.
- LSP semantic-token list (src/lsp/server.zig) updated.
- Lowering: `deriveObjcSelector` returns
`{ sel, keyword_count, is_override }`. When `is_override` is true,
the selector string is the user's literal and `keyword_count` is
the colon count in that literal. Both `lowerObjcMethodCall` and
`lowerObjcStaticCall` use the result.
Diagnostic policy when override colon-count ≠ call arity:
- Default mangling path: stays an error (`.err`). The user can fix
the sx-side name to produce the right keyword count.
- Override path: downgrades to a warning (`.warn`). Rationale:
Obj-C's `objc_msgSend` doesn't validate colon-vs-arg the way JNI's
`GetMethodID` validates the descriptor — the runtime dispatches
regardless and the wrong-arity case becomes silent calling-
convention corruption. The compiler is the last line of defense
for this typo class, but the warning preserves the override's
escape-hatch character (deliberate mismatches still proceed).
Snapshot for `examples/ffi-objc-dsl-06-selector-override.sx` flips
from the pre-3.2 parser-error to working output:
static override non-null: true
The mismatch diagnostic text in
`examples/ffi-objc-dsl-04-mismatch.sx`'s snapshot is updated to
drop the "once that lands (3.2)" phrasing now that 3.2 is here.
165/165 example tests.
The session-long set of changes that lay the groundwork for the
Jai-literal implicit-Context-parameter refactor. Lots of accumulated
work; the new arrival is the implicit-ctx foundation (steps 1+2 of
the plan in current/CHECKPOINT-MEM.md):
Step 1 — `CAllocator :: struct {}` stateless allocator in
library/modules/allocators.sx, delegating directly to
libc_malloc/libc_free. `ConstantValue` in src/ir/inst.zig gains a
`func_ref: FuncId` leaf so nested aggregates can carry function
pointers (the inline Allocator value's fn-ptr fields). Switch
sites updated in emit_llvm.zig, print.zig, interp.zig.
Step 2 — `emitDefaultContextGlobal` in src/ir/lower.zig synthesises
a static `__sx_default_context` global with a nested-aggregate
init_val pointing at the CAllocator → Allocator thunks. The
second-pass `initVtableGlobals` in emit_llvm.zig is generalised
to handle `.aggregate` init_vals (re-emits after func_map is
populated so func_ref leaves resolve to real symbols).
Also folded in from earlier work this session:
- Phase 1.1: `xx value` heap-copy in `buildProtocolValue` routes
through `context.allocator` via the new `allocViaContext` helper.
- interp.zig: `marshalForeignArg` double-offset bug fixed —
`heapSlice` already adds `hp.offset` to the slice ptr, so the
extra `+ hp.offset` was scribbling memcpy/memset into adjacent
heap state, corrupting `heap.items[0]`. Symptom: `build_format`
at comptime produced zero bytes, all `print` calls failed.
- Lazy lowering: `lazyLowerFunction` now declares foreign-body
functions as extern stubs in the local (comptime) module so
cross-module foreign calls resolve.
- Allocator API: all stdlib allocators on one-line `init() -> *T`
(CAllocator/GPA: libc-backed; Arena/TrackingAllocator: parent-
backed; BufAlloc: embeds state at head of user buffer).
- issues 0038 (transitive #import), 0039 (chess + stdlib migration
fallout), 0040 (generic struct method dot-dispatch), 0041
(pointer types as type-arg), 0042 (alias name resolution) — all
fixed; regression tests in examples/.
- Diagnostic: `emitError` now embeds the lowering's
`current_source_file` and enclosing function in the literal
message; SX_TRACE_UNRESOLVED=1 dumps a Zig stack trace at the
emit site so misattributed spans can't hide where the failure
is.
- tools/verify-step.sh (all-platforms gate) and tools/scratch.sh
(interp/codegen parity tester) added.
Test suite: 152 example tests pass; chess builds + screenshots on
macOS / iOS sim / Android.
Flip the surface semantics for type-introducer directives: bare
`Foo :: #jni_class("path") { ... }` now means "DEFINE a new Java class
at that path" (sx-side provides the implementations). The `#foreign`
prefix modifier flips it back to "REFERENCE an existing class on the
foreign runtime." Matches how `#foreign` already reads in sx for C
function declarations (`printf :: ... #foreign;`).
Foo :: #foreign #jni_class("path/to/Foo") { ... } // reference
Foo :: #jni_class("path/to/Foo") { ... } // define
Foo :: #jni_main #jni_class("path/to/Foo") { ... } // define + main Activity
Compiler-side changes:
- New `hash_jni_main` lexer token (the launchable-Activity marker).
Existing `hash_foreign` is reused; no new modifier token there.
- `ForeignClassDecl` gains `is_foreign: bool` + `is_main: bool`.
`ForeignMethodDecl` gains `body: ?*Node` so defined-class methods
can carry sx-side implementations (foreign-class methods stay
`;`-terminated).
- Parser learns `tryParseForeignClassPrefix` — peek-and-consume the
modifier tokens, then dispatch to the unchanged
`parseForeignClassDecl` with the flags threaded through.
- Sema rejects two illegal combinations: `#foreign + #jni_main`
(can't be both an external reference and the app's main entry),
and bodied methods on `#foreign` decls (foreign methods are
runtime-provided).
- Lower's foreign-class dispatch errors on non-foreign decls with
a pointer to the runtime-synthesis follow-up; defined-class
codegen (Java class emission, RegisterNatives wiring, manifest
entry generation) lands in a separate session.
Migration:
- `library/modules/platform/android_jni.sx`: all four foreign class
decls (`Activity`, `Window`, `View`, `WindowInsets`) gain `#foreign`.
- `examples/ffi-jni-class-{01..08}*.sx`: every test's `#jni_class` /
`#jni_interface` / `#objc_class` / `#objc_protocol` / `#swift_class`
/ `#swift_struct` / `#swift_protocol` usage gains `#foreign`. All
9 files mechanical perl rename; snapshots unchanged.
Verified locally:
- `zig build test` clean.
- `bash tests/run_examples.sh` 129/129.
- `bash tests/cross_compile.sh` 3/3.
- Chess APK rebuilds, reinstalls, launches on Pixel; safe-area
clearance preserved.
New `hash_jni_env` lexer token; `parsePrimary` dispatches to a small
`parseJniEnvBlock` that consumes `(env) { body }` and returns a new
`JniEnvBlock` AST node (env_expr + body block).
Sema's analyzeNode arm recurses into env + body inside a pushed
scope; findNodeAtOffset descends through both children for go-to-
definition.
Lowering treats it as a syntactic wrapper around the block: env is
evaluated for side effects, body lowers as a normal block. The TL
push/pop semantics (synthesizing the env stack so `#jni_call`'s env
arg can become optional) land in 2.16b.
`expectSemicolonAfter` recognises `jni_env_block` as block-form so
statement-position uses don't need a trailing `;` — matches `if` /
`while` / `for` / bare blocks.
Test runs through the block body and prints expected output; xfail
snapshot flips to green. 127/127 examples green.
Six new lexer tokens (`hash_jni_interface`, `hash_objc_class`,
`hash_objc_protocol`, `hash_swift_class`, `hash_swift_struct`,
`hash_swift_protocol`) join the existing `hash_jni_class`. All seven
share the body grammar from Phases 2.1–2.6.
AST refactored: `JniClassDecl` → `ForeignClassDecl` with a
`runtime: ForeignRuntime` enum discriminator; `JniMethodDecl` →
`ForeignMethodDecl` (with `jni_descriptor_override` renamed for
clarity since it's JNI-only); `JniFieldDecl` → `ForeignFieldDecl`;
`JniClassMember` → `ForeignClassMember`. AST variant renamed
`jni_class_decl` → `foreign_class_decl`.
`parseForeignClassDecl` takes the runtime as a parameter; the
`parseConstBinding` dispatch table now maps each of the seven
directive tokens to its `ForeignRuntime` variant via
`foreignRuntimeForCurrent`. No codegen yet — Phase 3 picks up Obj-C
runtime, Phase 4 picks up Swift. Runtime-specific body items (fields,
descriptor override) are validated at sema time in later steps.
126/126 examples green.
New `hash_jni_method_descriptor` lexer token + LSP keyword
classification. `JniMethodDecl` gains `desc_override: ?[]const u8`.
parseJniClassDecl accepts an optional `#jni_method_descriptor("...")`
clause between the return type and the terminating `;`, stashing the
literal as the override. Auto-derivation in Phase 2.8 will treat
this as the precedence override when present.
The 2.6 xfail commit (0ed4799) used the working name `#desc` in its
test file; this commit renames to `#jni_method_descriptor` for
parallel naming with the rest of the FFI directive set (`#jni_call`,
`#jni_class`, `#jni_env`, ...). Test snapshot flips xfail → green.
125/125 examples green.
Two new lexer tokens `hash_extends` / `hash_implements` (global tokens,
context-meaningful inside #jni_class bodies — same pattern as #using).
`JniClassDecl.methods` refactored into `members: []const JniClassMember`,
a tagged union with `method` / `extends` / `implements` variants.
Body loop dispatches on the leading token: `#extends Alias;` /
`#implements Alias;` consume the alias name and push a non-method
member; everything else falls through to the existing method path.
The alias on the right of `#extends` is the sx-side name (resolved
to the corresponding #jni_class at sema time in a later step), not
the foreign Java path — the path lives only in the alias's own
directive arg.
123/123 examples green.
New `hash_jni_class` token + lexer entry, `JniClassDecl` AST node
(alias + java path; body deferred to 2.2+), `parseJniClassDecl`
consuming `("...") { }` and rejecting non-empty bodies for now.
Sema registers the alias as a type_alias symbol; LSP classifies
the directive as a keyword. The 2.0 xfail snapshot flips to
`parse-only ok`, exit 0.
120/120 examples green; zig test clean.
98/98 regression tests pass; ffi-objc-call-01-parse flips from
parse-error xfail to passing.
Shape: `#<intrinsic>(ReturnT)(args...)`. The return-type generic
sits in the first parens, the actual call args in the second. All
three intrinsics share the same parse rule; only the kind tag and
the downstream lowering differ.
token.zig | three new hash_* tags
lexer.zig | matches the directive keywords with the same
isIdentContinue boundary check as the rest
ast.zig | FfiIntrinsicCall node with `kind`, `return_type`,
and `args` fields; FfiIntrinsicKind enum
parser.zig | parseFfiIntrinsicCall — same call-arg loop shape
as Call, with the leading return-type slot
sema.zig | analyzeNode + findNodeAtOffset arms walk the args
+ return-type child nodes
lsp/server.zig | classify the new tokens as ST.keyword
Codegen for the new intrinsic isn't wired yet — examples that
reach the body of a non-suppressed call would fail at lowering.
The current parse test uses `inline if false { ... }` to suppress
the dead branch, so sema/codegen don't see the node. Phase 1.3+
adds the lowering and the gate comes off.
Chess Android + iOS-sim builds clean — no regression on the
existing `objc_msgSend` cast pattern or the JNI helper.
Android (toolchain):
--target android / --target android-arm64 → aarch64-linux-android21.
target.zig discovers $ANDROID_NDK_HOME (or scans
~/Library/Android/sdk/ndk/* for the newest), invokes the NDK clang
with -shared -fPIC and links libsxhello.so against -llog -landroid
-lEGL -lGLESv3 -lm -ldl. native_app_glue.c from the NDK is compiled
and linked alongside the sx .o so apps can use the conventional
android_main(struct android_app*) shape; -u ANativeActivity_onCreate
keeps glue's symbol live.
Android (APK):
--apk <out> wraps the .so into a debug-signed installable APK.
target.zig discovers the SDK at $ANDROID_HOME (or
~/Library/Android/sdk), picks the newest build-tools + platforms,
generates a NativeActivity AndroidManifest.xml from --bundle-id,
packages via aapt2 link, appends the lib/ tree, zipalign, then
apksigner against ~/.android/debug.keystore (auto-generated via
keytool on first use). One command end-to-end:
sx build --target android --apk out.apk \\
--bundle-id co.swipelab.foo main.sx
Verified on Pixel 7 Pro: install + launch reaches android_main.
Compiler (entry-point linkage):
Top-level fn defs default to LLVM internal linkage and are lazily
lowered (only `main` was eagerly lowered before). Added
isExportedEntryName() — a small allowlist for names the OS loader
calls: `main`, `android_main`, `ANativeActivity_onCreate`,
`JNI_OnLoad`. These get eagerly lowered AND keep external linkage,
so they actually land in .dynsym.
LSP (imports):
DocumentStore now takes the install-discovered stdlib_paths and
forwards them into resolveImportPath, mirroring the compiler. Before
this, every `#import "modules/..."` resolved through the stdlib path
failed silently inside the LSP and identifiers from those modules
showed as `undefined variable`. Repro on label.sx: 1 false positive
before, 0 after.
- examples/modules/ -> library/modules/ (top-level, no more
symlink hacks in consumer projects)
- compiler discovers stdlib via _NSGetExecutablePath / readlink
/proc/self/exe; searches dev layout (../../library), install
layout (../library), and alongside-binary fallback
- SX_STDLIB_PATH env var overrides for tests / dev convenience
- SX_DEBUG_STDLIB env var dumps the discovery results
- build.zig installs library/ alongside the binary
- Compilation gains stdlib_paths field threaded through resolveImports
- 50 tests pass; consumer projects can now build from any cwd
