emulators-code-complexity-audit

Measure and audit C/C++ code size, namespace distribution, function complexity, nesting, recurrence, and namespace coupling in the EMULATORS framework. Use when Codex needs codebase statistics, complexity baselines, namespace comparisons, duplication indicators, hotspots, architectural growth analysis, or before/after complexity reports while excluding third-party code.

EMULATORS Code Complexity Audit

Workflow

  1. Run scripts/analyze_complexity.py from the repository root. Its default scope is include/ and src/.
  2. Use Markdown for a human review and JSON when results will be compared or processed later.
  3. Report totals and every requested ratio by namespace. Keep GLOBAL visible because it exposes unattributed implementation, macros, includes, and global declarations.
  4. Read references/metrics.md before interpreting recurrence, cyclomatic complexity, or namespace attribution limitations.
  5. Inspect the listed hotspot functions and repeated blocks before proposing refactors. Treat the script as a deterministic screening tool, not a full C++ parser.

Commands

python .codex/skills/emulators-code-complexity-audit/scripts/analyze_complexity.py
python .codex/skills/emulators-code-complexity-audit/scripts/analyze_complexity.py --format json --output complexity.json
python .codex/skills/emulators-code-complexity-audit/scripts/analyze_complexity.py projects emulators tests
python .codex/skills/emulators-code-complexity-audit/scripts/analyze_complexity.py --namespace COMMODORE --namespace C64

Reporting Rules

  • State the scanned paths, extensions, exclusions, and number of files.
  • Use code lines, not physical lines, as the denominator for namespace ownership percentages.
  • Present namespace totals before individual hotspots.
  • Keep recurrence and cyclomatic complexity labelled as heuristic.
  • Compare changes using JSON generated with identical paths, exclusions, and block size.
  • Do not include thirdparties/, generated output, binaries, documentation, or Codex metadata unless explicitly requested.
