        <pre>Hi,

when definitions of a macro spans several lines,
clang-format does this:

$ clang-format-5.0 foo.cc
#define FOO(x)                                                   \
  try {                                                          \
    ::foo::do_something(x);                                      \
  } catch (...) {                                                \
    throw ::foo::special_exception;                              \
  }

I can also do this:

$ clang-format-5.0 -style='{AlignEscapedNewlinesLeft: true}' foo.cc
#define FOO(x)                      \
  try {                             \
    ::foo::do_something(x);         \
  } catch (...) {                   \
    throw ::foo::special_exception; \
  }

But what I really want is, no alignment of the backslashes:

$ cat foo.cc
#define FOO(x) \
  try { \
    ::foo::do_something(x); \
  } catch (...) { \
    throw ::foo::special_exception; \
  }

Did I overlook a way to achieve this?
If not, I'd request to add a AlignEscapedNewlines: true/false switch
(or remove AlignEscapedNewlinesLeft and add
AlignEscapedNewlines: None/Left/Right instead)

Thank you very much.

Stephan</pre>
