If you want to reformat the output so it looks different you can use templates.

To get Visual Studio compatible output you can use "--template vs":

cppcheck --template vs gui/test.cpp

This output will look like this:

Checking gui/test.cpp...
gui/test.cpp(31): error: Memory leak: b
gui/test.cpp(16): error: Mismatching allocation and deallocation: k

To get gcc compatible output you can use "--template gcc":

cppcheck --template gcc gui/test.cpp

The output will look like this:

Checking gui/test.cpp...
gui/test.cpp:31: error: Memory leak: b
gui/test.cpp:16: error: Mismatching allocation and deallocation: k

You can write your own pattern (for example a comma-separated format):

cppcheck --template "{file},{line},{severity},{id},{message}" gui/test.cpp

The output will look like this:

Checking gui/test.cpp...
gui/test.cpp,31,error,memleak,Memory leak: b
gui/test.cpp,16,error,mismatchAllocDealloc,Mismatching allocation and deallocation: k
