clang-format: Align asterisk (*) of pointer declaration with variable name

by

PointerAlignment: Right is unfortunately not implemented yet. See https://github.com/llvm/llvm-project/blob/master/clang/lib/Format/WhitespaceManager.cpp#L643 void WhitespaceManager::alignConsecutiveDeclarations() { if (!Style.AlignConsecutiveDeclarations) return; // FIXME: Currently we don’t handle properly the PointerAlignment: Right // The * and & are not aligned and are left dangling. Something has to be done // about it, but it raises the question of alignment of code like: … Read more

How to indent after access modifiers with clang-format

Where I work, we’ve stumbled upon the same problem. Since the IndentWidth parameter controls the indentation everywhere (classes, functions, etc.) what you’re trying to achieve seems impossible.

Since the corresponding SortIncludes option is set to true by several of the built-in styles, it might not be obvious that clang-format is going to reorder … Read more

How to auto indent a C++ class with 4 spaces using clang-format?

As near as I can tell, clang-format offers no option for indenting function contents differently from non-access-modifier class contents. That is, consider the following code: class A { public: void foo() {} } void bar() { int a; } In this code, the line “void foo() {}” will always be indented the same amount as … Read more
