<div>
<pre>The following C++ header file is confused for Objective-C code:
```
#pragma once
#include <memory>
class SomeClass : public Object {
int member;
};
void some_function() {
hello();
}
[[ noreturn ]] void other_function(int arg);
```
Removing the `[[ noreturn ]]` attribute results in correct detection.
My project uses a `.clang-format` configuration file that only specifies
configuration for `Language: Cpp`, and so invoking clang-format results in an
error:
$ clang-format -style=file simple.h
Configuration file(s) do(es) not support Objective-C:
/path/to/project/.clang-format
I also tried forcing language detection with:
$ clang-format -style=file -assume-filename=simple.hpp simple.h
but that results in the same error (I guess because this option is only active
when reading from stdin).
---
Workarounds:
$ mv simple.h simple.hpp
$ clang-format -style=file simple.hpp
Or:
$ cat simple.h | clang-format -style=file -assume-filename=simple.hpp</pre>
