I am running cppcheck on a big project and I'm trying to exclude a couple of files and folders that are 3rd party and/or generated. Is it possible to let cppcheck do a dry run and let it show the files it would normally try to check?
No, such a functionality is not (yet) implemented.
The best solution that comes to my mind is to use options like this:
cppcheck --check-config ./ 2> /dev/null
Explanation:
--check-config
option lets Cppcheck only check if includes are
missing. No further analysis is done, no bugs are reported../
with the path to the source files that you want to have the output for.2> /dev/null
suppresses Cppcheck messages for missing includes and other errorsRunning this on the Cppcheck sources I get an output like this:
$ ./cppcheck --check-config ./ 2> /dev/null
