How to make CLion use "#pragma once" instead of "ifndef ... def ..." by default for new header files?

By default, CLion will add the following lines to a newly created header file:

#ifndef SOME_NAME_H
#define SOME_NAME_H
.... your code here
#endif //SOME_NAME_H

But I like #pragma once more. How can I configure CLion so that it uses #pragma once by default for new header files?

Solution

  • Go to File-> Settings -> Editor -> File and Code Templates. You will find there 3 tabs, namely, Templates, Includes, and Code. Now under Templates choose for example C Header File. Insert #pragma once to replace its content. Now every time you add a new Header from project menu you will have your template.
