[TEST] Refactor instruction normalization and expand test coverage#302
[TEST] Refactor instruction normalization and expand test coverage#302
Conversation
- Completely rewrote the brittle `normalize_instruction` function in `evolverstage.py` to use a robust regex-based parser. - Added support for missing modifiers (defaults to .I), missing addressing modes (defaults to $), case-insensitivity, varied whitespace/tabs, and trailing comments. - Expanded `tests/test_instruction_normalization.py` with 12 comprehensive test cases covering these edge cases. - Verified that all 118 tests in the suite pass.

Returning "" for comment-only lines makes callers treat a non-instruction as successfully normalized, which is harmful in the unarchive workflow: the loop increments its line counter before calling normalize_instruction, so comment/header lines consume the warrior length budget without writing an instruction and the DAT padding step may no longer fill to the intended length. This can silently produce truncated warriors when importing third-party .red files that include metadata comments.

The new operand parser converts any non-numeric operand suffix (for example malformed tokens like $foo) into 0, which silently rewrites invalid instructions into valid-but-different code. In normalization paths this corrupts warrior behavior and makes bad input hard to detect; previously these cases raised and could be surfaced by callers (e.g., warning/skip logic in normalization mode) instead of mutating semantics to $0/#0.

This PR improves the robustness of the
normalize_instructionutility inevolverstage.pyand addresses a significant gap in test coverage.Changes:
Refactored
normalize_instruction:re.splitlogic with a robust regular expression (re.match) that correctly parses Redcode instructions even with non-standard formatting..I, and missing addressing modes default to$.mov->MOV).OPCODE.MODIFIER MODE VALUE,MODE VALUE.Expanded Test Suite:
tests/test_instruction_normalization.pyfrom basic happy-path tests to a comprehensive suite of 12 tests.Impact:
These changes prevent potential crashes and warrior corruption during the unarchiving and normalization processes, making the evolver much more resilient to varied Redcode source files. All existing and new tests pass successfully.
