All of a project's header files should be listed as descendants of the project's source directory without use of UNIX directory shortcuts . (the current directory) or .. (the parent directory). For example, project/Classes/Entity/Role/Role.h should be included as:

#include "Entity/Role/Role.h"

Prefer no spaces inside parentheses. The if and else keywords belong on separate lines.

	if (condition) { // no spaces inside parentheses
	... // 4 space indent.
	} else if (...) { // The else goes on the same line as the closing brace.
	...
	} else {
	...
	}

	// Sort conditional statements may be written on one line if this enhances readability.
	if (x == kFoo) return new Foo();

If not conditional on an enumerated value, switch statements should always have a default case (in the case of an enumerated value, the compiler will warn you if any values are not handled). If the default case should never execute, simply assert:

	switch (var) {
	case 0: // 4 space indent
	... // 8 space indent
	break;
	case 1:
	...
	break;
	default:
	assert(false); // If the default case should never execute, simply assert
	}

When you have a boolean expression that is longer than the standard line length, be consistent in how you break up the lines.

	if (
	this_one_thing > this_other_thing &&
	a_third_thing == a_fourth_thing &&
	yet_another && last_one
	) {
	...
	}

You may choose between =, (), and {}; the following are all correct:

	int x = 3;
	int x(3);
	int x{3};
	string name = "Some Name";
	string name("Some Name");
	string name{"Some Name"};

Last active October 18, 2015 08:09

Sections in public, protected and private order, each indented zero space.

	class MyClass : public OtherClass {
	public: // Note the 0 space indent!
	MyClass(); // Regular 4 space indent.
	explicit MyClass(int var);
	~MyClass() {}

	void someFunction();

	void setSomeVar(int var);
	int getSomeVar();

joyhuang9473 / team_c++_style_guide_constructor_initializer_lists.h

Created October 18, 2015 08:02

Constructor initializer lists can be all on one line or with subsequent lines indented four spaces.

	// When it all fits on one line:
	MyClass::MyClass(int var) : some_var_(var), some_other_var_(var + 1) {}

	// When it requires multiple lines, indent 4 spaces, putting the colon on
	// the first initializer line:
	MyClass::MyClass(int var)
	: some_var_(var), // 4 space indent
	some_other_var_(var + 1) { // lined up
	...
	DoSomething();

joyhuang9473 / team_c++_style_guide_namespace_formatting.h

Created October 18, 2015 08:05

The contents of namespaces are not indented.

	namespace {

	void foo() { // Correct. No extra indentation within namespace.
	...
	}

	} // namespace
