You can use External Tools in CLion.
Go to File->Settings->Tools->External Tools and click on the plus sign.
A window should pop up. Use a name of your choice.
For the Tool settings tab I’m using this configuration:
-
Program:
clang-format-3.7(you should use the name of your executable here) -
Parameters:
-i $FileName$ -
Working directory:
$FileDir$
Now, with your file open, you can go to Tools->External tools and run the config above. It basically calls clang-format and does inplace formatting.
You can also set a custom keymap to it, just search the name of your external tool in “Keymap” of the Settings menu.
