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).
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.
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).
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
