New checks

Changes in existing checks

  • Improved performance-faster-string-find check.

    Now checks std::basic_string_view by default.

  • Improved readability-else-after-return check now supports a WarnOnConditionVariables option to control whether to refactor condition variables where possible.

  • Improved readability-identifier-naming check.

    Now able to rename member references in class template definitions with explicit access.

  • Improved readability-qualified-auto check now supports a AddConstToQualified to enable adding const qualifiers to variables typed with auto * and auto &.

  • Improved readability-redundant-string-init check now supports a StringNames option enabling its application to custom string classes. The check now detects in class initializers and constructor initializers which are deemed to be redundant.

  • Checks supporting the HeaderFileExtensions flag now support ; as a delimiter in addition to ,, with the latter being deprecated as of this release. This simplifies how one specifies the options on the command line: --config="{CheckOptions: [{ key: HeaderFileExtensions, value: h;;hpp;hxx }]}"

Renamed checks

  • For ‘run-clang-tidy.py’ add option to use alpha checkers from clang-analyzer.
