CXX Plugin

Description / Features

This plugin adds basic support of C++ language into Sonar.

Current feature list:

• Basic size metrics:
  
  • Files (number of)
  • Lines
  • Lines of comments
  • Lines of code
  • Lines of commented out code
• Static code checking via Cppcheck, RATS and Vera++
• Dynamic checking for memory management problems via Valgrind
• Cyclomatic (McCabe) complexity metrics including: 
  • Projects complexity
  • Average function/method complexity
  • Average file complexity
  • Complexity distributions
• Code coverage metrics including:
  • Line coverage
  • Branch coverage
  • An aggregated coverage measure
• Unit test execution metrics including:
  • Successfully executed tests
  • Failed tests
  • Skipped tests
  • Execution time
• Recognition of code duplication
• Basic highlighting mode for C++ in Sonar UI

Dependencies

The Cxx-Plugin has an obligatory dependency on Java (of course... the plugin itself and all runners are Java programs).

Moreover, there are optional dependencies on:

• 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 (memcheck). Detects various memory management problems at runtime. Basically Linux only; just use the packages from your distribution.
  • CppNcss. Provides cyclomatic (McCabe) complexity measures. This is a Java program distributed as a zip archive. Just unpack and make sure the "bin" directory is in PATH.
• GCC, gcov, gcovr and Python for coverage determination. Install Python and place the script somewhere on the PATH.
  

Installation

1. Copy the jar-archive into <sonar home>/extensions/plugins/ directory
2. Restart the Sonar web server

Known limitations

TBD
