Part of the cxx plugin is the Squid sensor. The sensor is responsible for the following points:

• Parsing source code files and creating an AST (Abstract Syntax Tree). To be able to parse files error free with the C++ grammar a preprocessor is also called.
• calculate and create software metrics (LoC, Complexity, ...)
• execute cxx rules (checks) by calling the AST with the visitor pattern
• syntax highlighting of source code

Parsing C++ code can be very time consuming, especially if the preprocessor has to include many include files. The processing can therefore take longer.

The configuration of the Squid sensor is done with sonar.cxx.squid.disabled in the configuration file sonar-project.properties or SonarQube UI.

Sample for sonar-project.properties:

Disable parsing of source code, syntax highlighting and metric generation. The source files are still indexed, reports can be read and their results displayed. Turning off will speed up reading of source files. The default of the value is False.

sonar.cxx.squid.disabled=True
