How to call clang-format over a cpp project folder?

Question

Is there a way to call something like clang-format --style=Webkit for an entire cpp project folder, rather than running it separately for each file?

Answer 1

First create a .clang-format file if it doesn't exist:

clang-format -style=WebKit -dump-config > .clang-format

Choose whichever predefined style you like, or edit the resulting .clang-format file.

clang-format configurator is helpful.

Then run:

find . -regex '.*\.\(cpp\|hpp\|cc\|cxx\)' -exec clang-format -style=file -i {} \;

Other file extensions than cpp, hpp, cc and cxx can be used in the regular expression, just make sure to separate them with \|.

Answer 2

When you use Windows (CMD) but don't want to use the PowerShell cannon to shoot this fly, try this:

for /r %t in (*.cpp *.h) do clang-format -i -style=WebKit "%t"

Don't forget to duplicate the two %s if in a cmd script.

Answer 3

What about:

clang-format -i -style=WebKit *.cpp *.h

in the project folder. The -i option makes it inplace (by default formatted output is written to stdout).
