- 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.
- 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.
Mark as done:
- for x in collection iterator loops
- Trait bounds (T: Comparable)
- CTFE (compile-time const evaluation)
- Selfhost bootstrap loop (deterministic C output)
- Implicit generic type argument inference
- Mark capture-less closures as ✅ Done in ROADMAP
- Add closure syntax examples to LanguageRef.md Functions section
- Update PHASE8_STRATEGY.md Milestone A with closures
Updated documentation to reflect changes from the last 2 days:
ROADMAP.md:
- Mark string interpolation, named/default params, bux fmt/test/new/init,
and basic borrow checker as ✅ Done
- Update Recommended Order (next: closures)
PHASE8_STRATEGY.md:
- Update date, achievements, and milestone statuses
- Borrow checker is now ✅ working in selfhost
- CTFE, LSP, formatter, test runner marked done where applicable
LanguageRef.md:
- Add defer, switch/case, string interpolation (f"...")
- Add &T, &mut T, own T to composite types
- Add named/default parameters and operator overloading sections
- Expand @[Checked] rules with double-mut-borrow and use-after-move
- Update keywords and operators
STRATEGY.md:
- Update date and version (0.3.0 selfhost)
- Mark 8.2 borrow checker, 8.4 CTFE, 8.7 LSP as ✅
BuildAndTest.md:
- Add bux init, bux fmt, bux test commands
- Expand test sections with golden tests and Std::Test
Bootstrap compiler:
- ast.nim: add exprCallArgNames to ekCall for named arg tracking
- parser.nim: detect name: value syntax in call args
- sema.nim: add resolveCallArgs helper that injects default values
for missing params and reorders named args into param order.
Parser already parsed default param values; sema now uses them.
Selfhost compiler:
- ast.bux: add defaultExpr to Param, argName to ExprList
- parser.bux: parse = defaultExpr in param list, detect name: value
syntax in call arguments
- sema.bux: add Sema_ResolveCallArgs with same logic as bootstrap
Tests:
- _test_named_params verifies defaults, named args, mixed positional+named,
and named args with defaults in both compilers.
All verifications pass: build, selfhost-loop, test-examples, test-golden.
- Add operatorMethodName mapping (tkPlus -> operator_add, etc.)
- Add tryLowerOperatorCall / tryLowerIndexCall in HIR lowerer
- Modify ekBinary lowering to check method table before builtins
- Modify ekAssign lowering to detect ekIndex target and emit
operator_index_set method call when available
- Add sema type-checking for operator overloads in ekBinary
and ekIndex paths (method-table lookup before builtin rules)
- Fix sema compile errors: minfo.params[N].typ -> minfo.params[N]
- Fix hir_lower forward decl ordering for resolveExprType
- Update golden test expected.c files for current C backend
- Update ROADMAP.md and PHASE8_STRATEGY.md status
- Add statement for function-level deferred execution
- Deferred expressions run in LIFO order on function exit (return or implicit)
- Bootstrap: desugar defers in hir_lower.nim (inject before return + end of func)
- Selfhost: emit defers in c_backend.bux via CEmitter defer stack
- Both: add tkDefer token, skDefer AST node, hDefer HIR node
- Parser, lexer, sema, token files updated in both bootstrap/ and src/
