InsertNewlineAtEOF still does not insert a newline character at EOF in 20.1.8

[basilm4r0]

With this .clang-format config file:

InsertNewlineAtEOF: 'true'
KeepEmptyLinesAtEOF: 'true'

If I create a file called foobar.cpp and write to it:

int foobar () {
return 0;
}

and then run 'clang-format foobar.cpp', the output is:

int foobar() { return 0;}

No newline character is being inserted at the end of the file.

LLVM version is 20.1.8

As documented, InsertNewlineAtEOF inserts a newline at eof if missing.

Yes, and there is no newline at the end of the file text I attached, before or after formatting.

With clang-format 21.1.6:

$ cat a.cpp
int foobar () {
return 0;
}$ clang-format a.cpp
int foobar() { return 0; }$ clang-format -style='{InsertNewlineAtEOF: true}' a.cpp
int foobar() { return 0; }
$ 

As you can see, a newline was inserted at eof.
