2026-10-22refactor(codegen): remove dead parameters, fields and branches_ov4
Drop the never-read StackObject::IsCopy flag and registerStackObject parameter, the unused NewExprAST forward declaration, the unused Ret parameter of FunctionGen::emitReturn and CG parameter of ArrayHandler::loadElement, unused <cstdio> includes, and the coerceValueToType early returns already covered by the exact LLVM type check (builtin kinds always map to double/i64/i1/i8).

2026-10-21feat(driver): color diagnostics like gcc with -fdiagnostics-color_ov4
Add -fdiagnostics-color[=auto|always|never] and -fno-diagnostics-color. The default auto mode colors only a terminal stderr (TERM set and not dumb on Unix; a console that accepts VT sequences on Windows), so test harnesses, the desktop bundle and other pipes stay plain. Every diagnostic label now comes from cps::diagnosticPrefix, which emits gcc's default GCC_COLORS bytes: bold locus, bold red error/fatal error, bold magenta warning, bold cyan note. compilation terminated., runtime messages of the compiled program and lld output are unchanged.

2026-10-21feat(diagnostics): print source diagnostics in gcc file:line: layout_ov4
Lexer, parser, driver and codegen diagnostics now read "<path>:<line>: error: <message>" instead of "error: <message> at line N in <path>". The path is always printed as given on the command line. Call sites pass the bare message to cps::sourceError/sourceWarning, which carry printf format checking; reportError routes through the same helper. The suite iii harness parses the new layout and matches the reason against the message only. iii/template-class-pack-field passed only because its reason regex matched the case path, so it is now case-insensitive.

2026-10-20fix(strings): preserve enclosing class lifetimes during assignment_ov4

2026-10-20refactor(strings): replace compiler builtins with the STRING library_ov4

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): allow identical EXTERN redeclarations across files_ov4
Repeated EXTERN declarations with the same signature share one C symbol, as C declarations do; conflicting signatures are errors. 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>

2026-10-17refactor(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>
