Subject: clang-format: Add test for AlignAfterOpenBracket = AlwaysBreak in C++.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8025bf5092dd039c8605d93f94ceeafa3921de0b;p=clang

clang-format: Add test for AlignAfterOpenBracket = AlwaysBreak in C++.

Revision 251405 added AlwaysBreak to support Google's JavaScript style. This
changeset complete existing AlignsAfterOpenBracket tests to exercise
AlwaysBreak for C++.

I thought this would be worthwhile.  With this option we can support request
from http://lists.llvm.org/pipermail/cfe-dev/2015-May/042942.html, that had
been requested a few times. This also partially solve related Bug 23422 and is
probably sufficient for most people.

  AlignAfterOpenBracket = FormatStyle::BAS_AlwaysBreak;
  BinPackArguments = false;
  BinPackParameters = false;

With these setting we obtain this formatting:

  void fooWithAVeryLongParamList(
      int firstParameter,
      int secondParameter
      int lastParameter)
  {
      object.alsoThisDoenstFitSoIBreakImmidiatly(
          firstParameter,
          secondParameter,
          lastParameter);
  }

Patch by Jean-Philippe Dufraigne, thank you.
