In .cpp files you'll get your own include at the top, then sorted separate blocks according to how they should go.

If you read the docs on IncludeCategories you'll see the main header always gets priority 0.

Thanks for this file--you saved me a lot of time. The only change I've made so far is NamespaceIndentation to "All" from "None"

No problem :) sharing is caring!

Thank you @intinig
Just asking, is it possible to disable formatting for inline functions?
f.e:

FORCEINLINE class USpringArmComponent* GetCameraBoom() const { return CameraBoom; }

breaks it to

FORCEINLINE class USpringArmComponent* GetCameraBoom() const
{
	return CameraBoom;
}

@JanSeliv just place ; :)

FORCEINLINE class USpringArmComponent* GetCameraBoom() const { return CameraBoom; };

@JanSeliv just place ; :)

FORCEINLINE class USpringArmComponent* GetCameraBoom() const { return CameraBoom; };

yeah, thank you! :)

This is breaking my code, for example:

becomes:

And it doesn't compile, any idea what setting would be causing this?

Anyone have a similar configuration for clang-tidy?
