How to avoid clang-format to format two separate '>' into a shift?

Question

When I use clang to format my C++ codes, I ran into a problem:

priority_queue<int, vector<int>, greater<int> > q;

will be automatically formatted into:

priority_queue<int, vector<int>, greater<int>> q;

Two separate '>' will be formatted into a shift >>.

So how should I configure the .clang-format file to avoid this situation?

That's not a shift, and since C++11 is syntactically equal as the first. — Some programmer dude, Oct 22 '17 at 09:28
But this would lead to error: '>>' should be '> >' within a nested template argument list — Thesharing, Oct 22 '17 at 09:31
It will only be a problem with older compilers. Is that your problem, that you have to use an old pre-C++11 compiler? — Some programmer dude, Oct 22 '17 at 09:32
Yes, because I'm submitting code to OJ, it doesn't support C++11. — Thesharing, Oct 22 '17 at 09:33
A number of bypassers actually need to enable C++11 in a CMake project and go to [c++11 - How to activate C++ 11 in CMake? - Stack Overflow](https://stackoverflow.com/questions/10851247/how-to-activate-c-11-in-cmake "c++11 - How to activate C++ 11 in CMake? - Stack Overflow"). — Stéphane Gourichon, Aug 03 '18 at 21:35

There is the Standard option that you can use. You want the C++03 option (which would include C++98), as that would format double > in templates to include a white space in between them.

Standard: Cpp03

You can even use Auto instead so that clang-format can auto detect the C++ version used.

As an addition, the `Standard` option can also be set to `Auto`, in which case it will be formatted as C++11 if it looks like C++11 code, and C++03 otherwise. `Cpp03` (or equivalently, `C++03`) makes more sense in the OP's specific case, but `Auto` could be more appropriate if the OP wants to set it globally. – Oct 22 '17 at 09:43
@hvd Isn't `Auto` the default? So assuming that OP didn't not know about "Standard", `Auto` didn't work correctly? – Rakete1111 Oct 22 '17 at 09:45
No, the default is `Cpp11`, at least according to my system's `clang-format -dump-config` output. – Oct 22 '17 at 09:47
@hvd Ahh. Thanks for the info! :) – Rakete1111 Oct 22 '17 at 09:47
