CodeClone 1.2.0: Important fixes and improvements

BREAKING CHANGES

• CLI Arguments: Renamed output flags for brevity and consistency:
  • --json-out → --json
  • --text-out → --text
  • --html-out → --html
  • --cache → --cache-dir
• Baseline Behavior:
  • The default baseline file location has changed from ~/.config/codeclone/baseline.json to
    ./codeclone.baseline.json. This encourages committing the baseline file to the repository, simplifying CI/CD
    integration.
  • The CLI now warns if a baseline file is expected but missing (unless --update-baseline is used).

Added

• Detection Engine:
  • Deep CFG Analysis: Added support for constructing control flow graphs for try/except/finally, with/
    async with, and match/case (Python 3.10+) statements. The tool now analyzes the internal structure of these
    blocks instead of treating them as opaque statements.
  • Normalization: Implemented normalization for Augmented Assignments. Code using x += 1 is now detected as a clone of x = x + 1.
• Rich Output: Integrated rich library for professional CLI output, including:
  • Color-coded status messages (Success/Warning/Error).
  • Progress bars and spinners for long-running tasks.
  • Formatted summary tables.
• CI/CD Improvements: Clearer separation of arguments in --help output (Target, Tuning, Baseline, Reporting).

Improved

• Baseline: Enhanced Baseline class with safer JSON loading (error handling for corrupted files), better typing (
  using set instead of Set), and cleaner API for creating instances (from_groups accepts path).
• Cache: Refactored Cache to handle corrupted cache files gracefully by starting fresh instead of crashing.
  Updated typing to modern standards.
• Normalization: Added copy.deepcopy to AST normalization to prevent side effects on the original AST nodes during
  fingerprinting. This ensures the AST remains intact for any subsequent operations.
• Typing: General typing improvements across report.py and other modules to align with Python 3.10+ practices.
