+file_metrics: + max_complexity_per_function: + max: 10 # No function should be too complex + complexity: + max: 50 # Total file complexity +``` + +### Ensure Test Coverage Balance +```yaml +file_metrics: + number_of_functions: + max: 30 # Keep files focused + min: 1 # Ensure files have at least one function +``` + +### Monitor Function Size +```yaml +file_metrics: + max_rloc_per_function: + max: 50 # No giant functions + mean_rloc_per_function: + max: 20 # Keep average function size small +``` + +## Notes + +- The tool uses Jackson for YAML/JSON parsing (no CVEs in current version) +- Thresholds are applied only to files that contain the specified metrics +- All metrics are file-level; function data is aggregated as max/min/mean/median statistics +- The tool respects `.gitignore` files by default (use `--bypass-gitignore` to disable) +- Violations are grouped by metric type and sorted by severity within each group +- Only use `file_metrics` in your
