Changing the location of the line continuations ('\") used in macros with clang-format-CodePudding

I have code that uses Macros, some of them are long. Before running clang-format one example looks like the following:

    #define assertionTriggersExit { \
      std::cout.flush(); \
      std::cerr.flush(); \
      tarch::logging::Log::flushBeforeAssertion(); \
      assert(false); \
      exit(ASSERTION_EXIT_CODE); \
    }

After clang-format (scroll to see \ chars):

#define assertionTriggersExit                                                                                          \
  {                                                                                                                    \
    std::cout.flush();                                                                                                 \
    std::cerr.flush();                                                                                                 \
    tarch::logging::Log::flushBeforeAssertion();                                                                       \
    assert(false);                                                                                                     \
    exit(ASSERTION_EXIT_CODE);                                                                                         \
  }

The line continuations are placed at 120 characters, which is the column limit. I want clang-format to not change location of the \ characters (in general I want that they are either untouched and kept as in the original, or that they are 1-2 whitespaces away from the last character that is not ' '. I could not find the option (or the combination of options) to prevent it, could anybody help?

I am writing a fresh clang-format file based on the llvm style for a code base. The style file I have currently is as follows:

Try:

AlignEscapedNewlines: DontAlign

CodePudding user response：

I want that they are either untouched and kept as in the original

AlignEscapedNewlines: DontAlign

or that they are 1-2 whitespaces away from the last character that is not ' '

AlignEscapedNewlines: Left
