Error Recovery

Hint:
Parse error recovery is by default turned off
(sonar.cxx.errorRecoveryEnabled=false).
To enable it set 'General / Parse error recovery'
to true in the C++ plugin settings.

To get meaningful SonarQube results your code should be syntactically correct code. The C++ community plugin has error recovery on declaration level, but do not expect as much guidance as you can get from a C++ compiler.

Error recovery:

• Syntax errors within a declaration are skipped, analysis is continued with next declaration.
• For erroneous declarations the parser output the file, line number and closest identifier during analyzer run (e.g. sonar-runner).
• Rule to detected skipped code do support you to find issues: Enable 'Sonar \ C++ skip parser error' in your Quality Profile.

Example:

01: int i=0;
02: 
03: void func1()
04: {
05:    i=1 //;
06: }
07:
08: void func2()
09: {
10:    i=2;
11: }

The parser will find a syntax error in line 5 (missing semicolon). This results in a syntax error in the func1 declaration. You will get the error message below. The parser ignores the whole declaration starting from line 3 and ending with line 6. The parser continues with analysis in line 7 (func2 is analyzed again).
