[Nfd-dev] C++11 code style

[Junxiao Shi]

Dear folks

List initialization: I suggest the following rule:

rule x. List initialization should have the following form:

T object { arg1, arg2 };

T { arg1, arg2 };

new T { arg1, arg2 };

return { arg1, arg2 };
function({ arg1, arg2 }, otherArgument);

object[{ arg1, arg2 }];

T({ arg1, arg2 })


class Class
{

private:

  T m_member = { arg1, arg2 };

};

Class::Class()

  : m_member { arg1, arg2 }
{
}

T object = { arg1, arg2 };


Static assertion: I suggest the following rule:

rule x. BOOST_ASSERT and BOOST_ASSERT_MSG are preferred over assert.
BOOST_STATIC_ASSERT and BOOST_STATIC_ASSERT_MSG are preferred over
static_assert.
The reason is that BOOST_* macros are more eye-catching with upper case.

Right angle brackets: std::list<std::list<int>> should be preferred. This
doesn't need a new rule because it's not forbidden by any rule.

Strongly-typed enumerations: Yes we can use them. This doesn't need a new
rule because it's not forbidden by any rule.

STL classes and functions vs Boost classes and functions: This isn't a code
style problem. Generally STL is preferred.

Yours, Junxiao
