Jose Luis Montañes Ojados	65220f88c6	Add if statements, unary minus, and fix GC safe points ... - Lexer: recognize 'if' as keyword (TOK_IF) - Parser: add NODE_IF with if_statement union, parse if/cond/body, handle unary minus in parse_term as 0 - expr - Eval: add NODE_IF evaluation, move GC to NODE_BLOCK level to avoid destroying temporary values during sub-expression evaluation	2026-02-16 05:12:28 +01:00
Jose Luis Montañes Ojados	84b3abbfda	Add while loops, GC mark-and-sweep, and malloc block reuse ... - Lexer: add INDENT/DEDENT tokens, <, >, : operators, while keyword, closing DEDENT emission, include guards - Parser: add NODE_WHILE with while_loop union, parse while/cond/body blocks, include guards - Eval: add while loop evaluation, GC integration with roots from env, debug and gc flags, <, > comparison operators - GC: implement mark-and-sweep collector with 3 stages (mark roots, sweep unmarked, join free blocks) - Allocator: block reuse via first-fit search with splitting, exponential heap growth, NULL check on malloc, include guards, marked field in metadata - Object: add include guards, fix include to use allocator.h	2026-02-16 04:55:52 +01:00
Jose Luis Montañes Ojados	14b6a2ddd2	Add * and / operators, VM step debugger, and visualizer tweaks ... Support multiply and divide in lexer, parser and eval. Add step-by-step VM debug output with AST and heap visualization. Remove spacing in visualizer hex output.	2026-02-16 02:24:37 +01:00
Jose Luis Montañes Ojados	01740d4892	Add evaluator with environment and file-based execution ... Implements recursive AST evaluator with variable environment, reads .j files from command line args, and executes programs end-to-end (lexer -> parser -> eval).	2026-02-16 02:08:54 +01:00
