[Björn Schäpers via Phabricator via cfe-commits]

HazardyKnusperkeks added a comment.

In my opinion we are nearly done.



================
Comment at: clang/docs/ClangFormatStyleOptions.rst:3698
 
-      QualifierOrder: ['inline', 'static', 'type', 'const']
+      QualifierOrder: ['inline', 'static' , 'type', 'const']
 
----------------
Anyone knows where this comes from?
You are using the script to generate the rst, right?


================
Comment at: clang/include/clang/Format/Format.h:154
   /// \code
   ///   AlignConsecutiveMacros: AcrossEmptyLines
   ///

The example mentions explicitly only `AlignConsecutiveMacros` which is a bit misleading if you are only looking at the documentation of `AlignConsecutiveAssignments` for example.

This is not your fault, and I'm fine with ignoring it here. A separate patch to fix that is welcome. :)


================
Comment at: clang/lib/Format/WhitespaceManager.cpp:930
   unsigned Newlines = 0;
+  unsigned int NewLineThreshold = Style.AlignConsecutiveTrailingComments.AcrossEmptyLines ? 2 : 1;
   for (unsigned i = 0, e = Changes.size(); i != e; ++i) {
----------------
And accompanied by a short test. That should be everything to support the mixture of the options, right?


================
Comment at: clang/lib/Format/WhitespaceManager.cpp:984
+    }
+    else if (BreakBeforeNext || Newlines > NewLineThreshold ||
                (ChangeMinColumn > MaxColumn || ChangeMaxColumn < MinColumn) ||
----------------
Is this clang-format formatted?

Please revert this.
