- Rewrite apps/nexus with modular architecture:
Config, Http, Errors, Parser, Router, Handlers, Server, Main
- Use algebraic enums for ParseResult/FileResult/HttpError
- Thread-pool server via Channel<ConnectionTask> and spawn
- Fix C backend type ordering for generic struct instances
(Array_T, Iter_T) and algebraic enum struct payloads
- Collect Slice_T types from struct fields and enum payloads
- Fix match lowering for simple enums (direct value compare)
- Resolve match expression return type from first arm
- Infer element type for for-in over Array<UserStruct>
- Preserve generic type args in field access resolution
- Add fflush to PrintLine/Print for immediate server logs
- Add modern_features golden regression test
- Regenerate golden expected.c files
- Extend Lcx_BuildAutoDropFree to detect TypeName_Drop methods
registered by sema for extend Type for Drop impl blocks.
- Preserve existing @[Drop] attribute path and move semantics.
- Add design doc and implementation plan.
- Mark Destructors/Drop roadmap item done in selfhost.
- Export typeToTypeExpr from sema and preserve generic type args
- Derive loop variable type from collection element type in sema
- Substitute generic struct type params on field access
- Add getCollectionElementTypeExpr helper in hir_lower
- Replace placeholder collection for-in lowering
- Add Array/Iter lowering: Array_Iter_T / Iter_HasNext_T / Iter_Next_T
- Add Channel lowering: Channel_Recv_Ok_T loop
- Register loop variable in varTypeExprs before body lowering
Fixes _test_forin_stdlib, _test_forin_channel, _test_generic_trait, _test_import, _test_mono
- Preserve type args on tkNamed in resolveType
- Resolve explicit generic call return types with concrete substitutions
- Substitute method type params when looking up operator_index_get
- Skip strict arg checks for generic function calls (deferred to inference)
- Fix generic struct monomorphization when no caller substitution map exists
- Fix parameter varTypeExprs ordering so pointer params are visible in bodies
Fixes _test_drop_trait and _test_checked_index
- Add -Wl,--build-id=none to C compilation flags (removes non-deterministic build ID)
- Update Makefile selfhost-loop to strip debug info before ELF comparison
- Bootstrap compiler and selfhost compiler both deterministic
- @[Release] disables borrow checking and bounds checking in the function
- --release passes -O3 -flto to the C compiler for optimized builds
- Selfhost loop still deterministic
- Parse --target flag in Cli_Run before command dispatch
- Pass targetTriple through Cli_Build, Cli_BuildProject, Cli_RunProject
- Use clang with -target when cross-compiling, cc otherwise
- Selfhost loop: C output identical
Also fix runtime scheduler bugs:
- g_task_creating was thread-local but set on main thread and read on worker
- g_scheduler_context was global shared by all workers instead of per-thread
- Auto-drop now only triggers for user-defined types explicitly marked
with @[Drop] on the struct declaration.
- Added move tracking in C backend to skip auto-drop for variables
that have been moved (via let y = x, return x, or assignment).
- Prevents double-free when ownership is transferred.
- Selfhost bootstrap loop verified: C output is deterministic.
- lib/Drop.bux: interface Drop { func Drop(self: *Self); }
- sema.bux: define TypeName_MethodName in scope for impl block methods
so auto-drop (Lcx_BuildAutoDropFree) can find Drop implementations
via extend Type for Drop, not just @[Drop] or standalone functions
- Verified: extend Buffer for Drop auto-calls Buffer_Drop in @[Checked]
- ast.bux: add isDrop field to Decl
- parser.bux: parse @[Drop] attribute and attach to struct Decls
- hir_lower.bux: auto-drop now looks for TypeName_Drop for any type
- Test: _test_drop_user verifies Buffer_Drop is auto-called
- Auto-register func Type_Method(self: T, ...) as methods in sema.
- Add method table lookup for binary operators in sema.bux ekBinary.
- Add method table lookup for operator_index_get in sema.bux ekIndex.
- Add HIR lowering for binary operators to method calls in hir_lower.bux.
- Add HIR lowering for operator_index_get/set in hir_lower.bux.
- Set expr.refType for overloaded operators so chained ops work.
- Fix hir_lower.bux to recognize Array_int/Iter_string etc. in for-in loops
by checking Array_/Iter_ prefix outside the empty-elemTypeName branch.
- Update all golden expected.c files to include duplicate bux_bounds_check
declaration (matches actual C codegen).
- Remove duplicate Drop trait item from ROADMAP.md.
- Add lib/Slice.bux with Slice<T> generic struct
- Fix C backend to recognize Slice/Slice* as generic types
- Use var instead of let for uninitialized Slice<T> locals
- Selfhost loop passes, tests pass
