Description Features

This is a SonarQube plugin, which adds support for C++ language. It provides following features:

• Calculation of various size metrics (Number of lines/statements/classes/methods, LOC etc.)
• Feeding of code analysis results for virtually any analyzer, including but not limited to:
  • Cppcheck
  • RATS
  • Vera++
  • Valgrind
• Cyclomatic (McCabe) complexity metrics
• Code coverage metrics including:
  • Unit test coverage (line and branch)
  • Integration test coverage (line and branch)
  • Overall branch coverage (line and branch)
• Unit test execution metrics including
• Recognition of code duplication
• Basic highlighting mode for C++ in SonarQube UI

Dependencies

The plugin doesn't have obligatory dependencies.

However, you may need the following tools in order to extend the amount of metrics collected:

• Various external code analyzers:
  • Cppcheck: detects a wide range of problems ranging from performance issues and resource leakage to undefined behaviour. Binary packets are available on/for various platforms. Using the latest release pays off in general; compile from source if in doubt.
  • RATS: detects (potential) security problems in code, sensible for code bases with increased security requirements. Use binary packages or compile from source.
  • Vera++: focuses on code style issues. There's a binary package for Windows, users of other platforms are likely to compile themselves.
  • Valgrind: Detects various memory management problems at runtime. Basically Linux only; just use the packages from your distribution.
  • Pc-Lint. Static analyzer from Gimpel Software
• gcov, gcovr and Bullseye for coverage determination.

Known Limitations

• Not all of C++ can be parsed by now. You may hit parse errors when analyzing your project.
• The the plugin expects to be fed with syntactically correct code. This is a conscious design decision: we do not want to reimplement a compiler and try to follow the KISS principle. Do not expect as much guidance as you can get from a c++ compiler.
• The plugin doesn't know about standard include paths. You have to configure them manually using the property sonar.cxx.include_directories
