2026-10-18feat(driver): add #LIB directive hiding library lines in runtime errors_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-18feat(lexer): support C++ escape sequences in literals_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-18feat(operators): add member and unary overloads with explicit calls_ov4
Select member and global candidates together, enforce private access, and reuse argument marshalling. Materialize temporary receivers for chaining and register them for the existing object cleanup mechanism. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-18feat(operators): support global binary operator overloads_ov4
Resolve exact operand types and preserve declared operator return types. Reject implicit STRING to BOOLEAN conversion at typed expression boundaries. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-17feat(codegen): declare and call EXTERN C functions_ov4
Variadic arguments must be C values and receive C default argument promotions; narrow integer parameters carry sign/zero extension. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-17feat(parser): parse EXTERN "C" declarations and INCLUDE_OBJ_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

2026-10-17feat(parser): parse OVERLOAD prefix on FUNCTION and PROCEDURE_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-17refactor(runtime): write runtime diagnostics with fprintf(stderr)_ov4
Replace snprintf+write(2) with a single fprintf call on the platform's stderr: the C library's stderr / __stderrp, or __acrt_iob_func(2) on Windows, which the embedded runner binds to the host shim. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-17feat(runtime): write runtime diagnostics to stderr_ov4
Runtime check messages and the unhandled-exception message were printed to stdout by the generated program, so `cpsc x.cps -r >out.txt` captured them. They are now formatted with snprintf and written with write(2). Test expectations and docs are updated accordingly. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-17feat(codegen): FUNCTION MAIN entry point_ov4
Invoke the internal entry function through the generated exception handler and truncate its INTEGER result to the process exit status. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-17feat(driver): compile multiple source files with INCLUDE visibility_ov4

Use standard WHILE headers and default-public class fields, resolve pseudocode identifiers without case sensitivity, and check signed i64 literal boundaries before conversion. Preserve source locations across recursive emission and function diagnostics. Add 22 regression cases and update compiler examples and documentation. Validated all 69 CTest entries with the original Linux Actions seed and verified the release package's embedded, native and IR output paths.

2026-10-15fix(codegen): restore runtime diagnostics before throwing_ov4
Reuse historical runtime messages and source-line reporting for arithmetic, array, enum, pointer and file checks while preserving anonymous exceptions. Update the manuals and subsystem guidance to describe diagnostic output. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
2026-10-15fix(codegen): prevent NUM_TO_STR buffer overflow_ov4

2026-10-14feat(parser): add explicit parenthesized type casts_ov4

2026-10-14feat(types): add native C scalar types and imported aliases_ov4
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
2026-10-13feat(compiler)!: add try-catch with C++ stack unwinding_ov4
Add TRY/CATCH/ENDTRY and anonymous THROW statements. Use LLVM exception handling and the C++ ABI to propagate exceptions across function calls, clean up catch state, and handle uncaught exceptions at the program boundary. Register exception runtime symbols for the statically linked embedded runner. Verify runtime checks, nested catches, returns, loops, and invalid syntax with smoke programs; exercise unwinding with MCJIT, lli, and native binaries. BREAKING CHANGE: Runtime check failures now throw anonymous exceptions and print only a generic message when uncaught. Native binaries require linking the C++ runtime.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
2026-07-26fix: close type-safety holes found by adversarial review; update docs_ov4
Review findings (all reproduced, then fixed and re-verified): - '^x' leaked as a raw address into any builtin context (s <- ^x printed the variable's bytes as a C string; NOT ^x, '&', and ^x = ^x compiled). Address-of is now rejected everywhere except a pointer-typed target. - A whole-array variable passed the nominal gate as a value of its ELEMENT type (s <- arrayOfSeason stored the raw data pointer; = on it emitted invalid IR). Whole arrays are now rejected as operands and as coercion sources; array parameters are unaffected. - Enum values smuggled into INTEGER through array subscripts and DECLARE bounds (a[Autumn], ARRAY[Spring:Winter]); both now go through emitCoercedExpr like every other INTEGER context. - An array DECLAREd inside an IF/WHILE/REPEAT/FOR body and used after the block was a wild-pointer write (constant bounds) or a verifier dump (runtime bounds). Arrays are now block-scoped: control-flow bodies snapshot and restore the ArrayTable, so escape is a clean compile error. - Duplicate parameter names silently shadowed (BYREF write-back defeated); now a parse error. Trailing comma in parameter lists accepted; now a parse error consistent with every other list. - A variable/array/parameter/function could reuse a TYPE name; reserved. - RETURN with a value inside a PROCEDURE was silently discarded (control did not return); now an error, as is a bare RETURN in a FUNCTION. - INPUT r.f mis-parsed into a three-error cascade; now one clear error. - Assigning to an enum constant now says so instead of 'Unknown variable'. Docs: ARCH/CONVENTIONS/EXTENDING/SUBSYSTEMS/PITFALLS rewritten for the TYPE system (ABI additions, nominal-typing invariants, admission-gate doors, array-parameter ABI, new recipes, new sharp edges); README features/TODO updated — random files are unblocked.

2026-07-26feat: whole arrays (and records) as FUNCTION/PROCEDURE parameters_ov4
- Parameter syntax lands end-to-end: ARRAY OF T (rank 1, bounds travel with the argument) and ARRAY[l:u,...] OF T (any rank, literal bounds as a checked contract). Element type and rank must match exactly. - Flattened ABI: each rank-R array parameter becomes a data pointer plus kBoundArgsPerDim i64 bounds per dimension. The callee rebuilds ArrayMetadata from those bounds (ArrayHandler::bindArrayParameter via a binder callback injected by CodeGen, so FunctionGen stays ignorant of the array subsystem); the checked-indexing pipeline is reused unchanged. - BYVAL (the CIE default) copies the whole buffer at callee entry (malloc+memcpy, never freed — consistent with the string policy) so callee writes stay invisible; BYREF binds the caller's buffer. - Bounded-parameter contract: compile-time comparison when the caller's bounds are constants, else a runtime [Fatal] check (RuntimeCheck::emitArrayArgBoundsCheck). - marshalCallArgs gains the array branch and a call-site line number (CallStmtAST now carries one); whole-array-to-scalar keeps a clear error, FUNCTION RETURNS ARRAY is a dedicated parse error. - Verified: BYREF fill/sort-style mutation, BYVAL copy invisibility, 2-D bounded params, ARRAY OF <record> with field writes through the parameter, bounds-contract mismatches at compile time and run time.
