Direzione di ricerca

The traceback points to parse_checker_config_new in codechecker_analyzer/analyzers/clangtidy/analyzer.py, where yaml.safe_load receives the output of clang-tidy -dump-config. That output begins with a Resource filename: line before the --- document marker, which the YAML parser rejects. Start by reproducing the failure with the --checker-config example, or by running clang-tidy -dump-config -checks=* and loading the result with yaml.safe_load. Done means the config is parsed without error and the readability-function-cognitive-complexity:Threshold option validates. Check the open thread first, since the issue has had no activity for over a year.
