2026-10-30docs(types): explain implicit constructors and raw text literalsHEADmain_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-28docs(overload): document default return selection_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-27docs(preprocessor): document switches and library regions_ov4
Add manuals and aliases for all five PP directives, replace the retired #LIB page, and update compiler and shared-editor architecture notes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-27docs(memory): describe standard-library allocation and explicit imports_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-24docs(overload): document return-type selection across keyword pages_ov4
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
2026-10-24feat(operator): select operator overloads by the expected result type_ov4

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.

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)!: reject implicit BOOLEAN, CHAR and INTEGER mixing_ov4
Arithmetic and unary minus accept only INTEGER and REAL, AND/OR/NOT need BOOLEAN, comparisons need equal types (or INTEGER with REAL), and only INTEGER converts implicitly to REAL. Use ASC and CHR for characters. No existing test program relied on the now-illegal mixing, so none changed. Co-Authored-By: Claude Sonnet 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.
