title: Configuring clang-format for isocpp's core guidelines
body: <p>I want to follow the <a href="https://github.com/isocpp/CppCoreGuidelines" rel="nofollow">CppCoreGuidelines</a> as close as possible but I have some problems configuring clang-format.</p>
  
  <p>How do I configure clang-format to conform with the isocpp core guidelines?</p>
  
  <p>For example the following guideline gives me some trouble.</p>
  
  <p><a href="https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Rl-ptr" rel="nofollow">https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Rl-ptr</a></p>
  
  <p>clang-format always seems to choose <code>T &amp;operator[](size_t);</code> and I am unable to find the correct setting for it.</p>
