Supported languages

C++

CLion comes with two language engines. CLion's own language engine is the basis for all smart IDE actions and fully supports C++ standards up to C++14 (except for some constexpr cases) and some C++17 features. It works with libc++ and Boost, and correctly handles templates and macros.

An experimental complementary clangd-based language engine is used only to show errors and warnings in the editor.

C++ features supported by CLion

C

CLion supports C standards up to C99, C11 is supported partially (C11 keywords are completed: _Thread_local, _Alignas, _Noreturn, _Static_assert, and _Atomic).
