2026-10-30refactor(strings): construct string values implicitly from raw literals_ov4
Keep double-quoted literals and text constants as C_STRING values. Use marked STRING constructors for text and CHAR conversion, preserving string operations and I/O through the existing class machinery. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-30feat(types): support implicit single-argument constructors_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-27feat(library)!: replace #LIB with __LIB source regions_ov4
Track library mode by original source line, including deferred template bodies and automatic object cleanup. Update call lines from ordinary code and migrate the embedded standard library to PP_DEFINE __LIB. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-27refactor(memory)!: move allocation functions into memory.cps_ov4
Route keyword NEW and DELETE through the same library runtime and retain allocation tracking, runtime diagnostics and exception behavior. BREAKING CHANGE: -no-std programs using NEW or DELETE must explicitly import memory.cps. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-24feat(operator): select operator overloads by the expected result type_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-24feat(overload): select overloads by return type as well as parameters_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-22feat(input)!: validate INPUT and read whole lines into STRING_ov4
Scalar INPUT now reads one whitespace-delimited token through module-local IR helpers instead of scanf, then skips spaces and tabs and consumes one newline. INTEGER, REAL, BOOLEAN (TRUE or FALSE in any case) and CHAR are validated, and bad input or end of input is a runtime error. STRING INPUT reads the rest of the line. The unused scanf and REAL printf format globals are removed. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-22feat(codegen): convert implicitly between CHAR and STRING_ov4
A CHAR becomes a one-character STRING in &, comparisons, assignment, parameter passing and RETURN. A STRING becomes a CHAR in assignment, parameter passing and RETURN, with a runtime error when its length is not 1. CHAR with INTEGER or BOOLEAN still does not convert. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-22feat(codegen): short-circuit AND and OR_ov4
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-22feat(codegen)!: require explicit REAL to INTEGER conversion and add INT_ov4
Implicit REAL to INTEGER is now a compile error with an INT(...) hint. INT is a compiler builtin that truncates toward zero and raises a runtime error for NaN or values outside the INTEGER range. No existing test program relied on the implicit conversion. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
2026-10-22feat(codegen): pass C-struct records by value as variadic arguments_ov4
A variadic EXTERN call is now arranged by clang per call, from the fixed parameter count and the promoted argument types. C-struct records pass unchanged in variadic positions, as C11 6.5.2.2p6-7 and 7.16.1.1p2 allow; a record that is not a C struct names the offending field. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-22refactor(codegen): split large emitStmtImpl arms into methods_ov4
Move the self-contained FunctionDef, INPUT, OUTPUT and READFILE branches of emitStmtImpl into private emitFunctionDefStmt, emitInputStmt, emitOutputStmt and emitReadFileStmt methods. The dispatch order and the branch bodies are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-22refactor(codegen): share writable variable lookup_ov4
emitLValue (variable and designator base) and plain assignment repeated the same lookup, enum-or-unknown diagnostic and requireWritable check. Move it into a private lookupWritableSymbol helper. READFILE keeps its own lookup, which has no enum diagnostic. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-22refactor(codegen): share record field default construction_ov4
copyClassValue, emitConstruct and emitStringFromCString each walked the record fields and default-constructed those that need it. Move the loop into a private emitFieldDefaults helper; each caller passes the same line as before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-22refactor(codegen): share file keyword filename operand emission_ov4
EOF, OPENFILE, READFILE and CLOSEFILE each rejected a whole-array filename and then emitted it as a C string. Route them through a private emitFileNameOperand helper; diagnostics are unchanged. WRITEFILE keeps its own combined check. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

2026-10-18feat(classes): add copy constructors and statement-scoped temporaries_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>

2026-10-16fix(compiler): correct CIE semantics and diagnostic locations_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.

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>
2026-10-13feat: embed a statically linked LLVM execution engine_ov4
Add EMBEDDED mode to run generated modules in-process without lli or PATH lookup. Link LLVM and support archives plus the C++ runtime statically, while retaining the system C runtime on Linux. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
2026-10-13feat: compile source files with configurable IR output_ov4
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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 โ€” 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
2026-07-26feat: records with designator lvalues, and pointer types (CIE 4.1/4.2)_ov4
- New CodeGen::emitLValue resolves any designator โ€” variable, checked array element, record field chain (CreateStructGEP via the record payload), pointer deref (with the null-pointer [Fatal] check) โ€” to an address + type name; loadFromLValue centralizes the rvalue read and the STRING null->"" guard, so zero-initialized STRING fields read as "". - Designator assignment stores through emitLValue + emitCoercedExpr; whole-record copies (r2 <- r1, array elements, BYVAL args, RETURN) are aggregate loads/stores with name-checked admission. - getExprTypeInfo walks designator chains statically (field types from the record payload, deref to the pointee), so records/pointers type correctly in every expression context. - Address-of ^x admits into a pointer target only when the designator's type name equals the declared pointee exactly (nominal, strict: the guide's own ^INTEGER-at-a-Season example is a compile error by design); ^arr[i] and ^rec.field work through the same lvalue path. - Verified: the guide's ยง4.2 StudentRecord example (minus DATE), nested records, arrays of records with Form[i].YearGroup writes, record BYREF/BYVAL params, NodePtr = ^Node forward reference with writes through n1.Next^.Data, unset-pointer deref dying with [Fatal].
