PHP’s use isn’t the same as C++’s using namespace; it allows you to define an alias, not to “import” a namespace and thus henceforth omit the namespace qualifier altogether. So, you could do: use Blog\Article as BA; … to shorten it, but you cannot get rid of it entirely. Consequently, use Blog is useless, but … Read more
For completeness there are several ways to achieve the “benefits” you might get from namespaces, in C. One of my favorite methods is using a structure to house a bunch of method pointers which are the interface to your library/etc.. You then use an extern instance of this structure which you initialize inside your library … Read more
Most C++ users are quite happy reading std::string, std::vector, etc. In fact, seeing a raw vector makes me wonder if this is the std::vector or a different user-defined vector. I am always against using using namespace std;. It imports all sorts of names into the global namespace and can cause all sorts of non-obvious ambiguities. … Read more
But why does Sparta in MakeItReturnFalse() refer to {namespace}.Place.Sparta instead of {namespace}.Sparta? Basically, because that’s what the name lookup rules say. In the C# 5 specification, the relevant naming rules are in section 3.8 (“Namespace and type names”). The first couple of bullets – truncated and annotated – read: If the namespace-or-type-name is of the … Read more
Version 2 is unclear and not easy to understand because you don’t know which namespace MyClass belongs to and it’s just illogical (class function not in the same namespace?) Version 1 is right because it shows that in the namespace, you are defining the function. Version 3 is right also because you used the :: … Read more
You can call source(“abc.R”) followed by source(“xyz.R”) (assuming that both these files are in your current working directory. If abc.R is: fooABC <- function(x) { k <- x+1 return(k) } and xyz.R is: fooXYZ <- function(x) { k <- fooABC(x)+1 return(k) } then this will work: > source(“abc.R”) > source(“xyz.R”) > fooXYZ(3) [1] 5 > … Read more
C++17 might simplify nested namespace definition: namespace A::B::C { } is equivalent to namespace A { namespace B { namespace C { } } } See (8) on namespace page on cppreference: http://en.cppreference.com/w/cpp/language/namespace
It should have worked correctly if you had magrittr listed in Depends. However, this is not advised. Instead, you leave magrittr in Imports and add the following line to NAMESPACE: importFrom(magrittr,”%>%”) I suggest reading Writing R extensions. Your question is covered in paragraphs 1.1.3 and 1.5.1.
The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project. You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.
I don’t recommend you to name a class like its namespace, see this article. The Framework Design Guidelines say in section 3.4 “do not use the same name for a namespace and a type in that namespace”. That is: namespace MyContainers.List { public class List { … } } Why is this badness? Oh, let … Read more
