From 344206d57e834b2394cbe2ec0df50b04a8b3c171 Mon Sep 17 00:00:00 2001 From: _ov4 Date: Sun, 26 Jul 2026 15:45:40 +0000 Subject: feat: implement CIE 9.1 text file handling (OPENFILE/READFILE/WRITEFILE/CLOSEFILE/EOF) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Front end: OPENFILE/READFILE/WRITEFILE/CLOSEFILE plus reserved mode keywords READ/WRITE/APPEND (RANDOM reserved with a dedicated not-implemented error); statement nodes in new FileAST.h, parsing in new ParserFile.cc; EOF joins the Builtins table as the 12th builtin and CallExprAST now carries a line number for its runtime diagnostics. Runtime: new FileHandler (StringHandler-shaped leaf) lazily synthesizes internal __cps_file_* helper functions and a 16-slot open-file table keyed by filename content (strcmp — STRING '=' is pointer identity). EOF is an fgetc/ungetc peek; READFILE grows a malloc/realloc line buffer and strips a trailing CR; fopen uses text modes so mingw-w64 line translation works. File-free programs get byte-identical IR. All misuse (not open, wrong mode, reopen, fopen failure, read past EOF, table full) dies with the existing "[Fatal] line N:" pattern via a new RuntimeCheck::emitErrorAndExit overload taking runtime printf args. Also fixes a pre-existing ArithmeticHandler hole surfaced by adversarial review: mixed-width integer operands (i1 BOOLEAN / i8 CHAR vs i64) now widen via ZExt instead of emitting invalid IR, and remaining type mismatches get a clean diagnostic; -EOF(f) and -IS_NUM(x) compile.
