Jared Miller	72dd047b7b	Port 5 complex opcodes to hybrid z-machine interpreter ... Implement op_sread (text input), op_save/restore (file I/O stubs), op_restart (exception-based reset), op_input_stream and op_sound_effect (no-op stubs). Add ZCpuRestart exception. All implementations follow TDD with comprehensive unit tests.	2026-02-09 20:44:22 -05:00
Jared Miller	c76ee337d3	Port 4 medium opcodes to hybrid z-machine interpreter ... Implements op_print_addr, op_print_num, op_ret, and op_show_status following TDD approach with tests first. Each opcode now properly decodes/prints text, handles signed numbers, returns from routines, or acts as a no-op as appropriate.	2026-02-09 20:44:22 -05:00
Jared Miller	1b9d84f41a	Port 10 object tree opcodes to hybrid z-machine interpreter ... Implemented 10 opcodes for object tree manipulation: get_sibling, test_attr, set_attr, clear_attr, jin, remove_obj, print_obj, get_prop_addr, get_next_prop, and get_prop_len. Added 6 supporting methods to ZObjectParser: set_attribute, clear_attribute, remove_object, get_property_data_address, get_next_property, and get_property_length. Fixed bug in insert_object where sibling chain walk never advanced the prev pointer, potentially causing infinite loops. Added 16 unit tests with MockObjectParser to verify CPU opcode behavior. All tests passing.	2026-02-09 20:44:21 -05:00
Jared Miller	5ea030a0ac	Re-copy fixed repos/zvm source into src/mudlib/zmachine ... Copies the cleaned-up zvm source (ruff-compliant, ty-clean) back into the zmachine module. Adds __init__.py with proper exports and updates .gitignore for debug.log/disasm.log.	2026-02-09 20:44:21 -05:00
Jared Miller	dcc952d4c5	Port 12 trivial opcodes to hybrid z-machine interpreter	2026-02-09 20:44:21 -05:00
