I'm new to Structured Text programming and I'm currently working on TwinCat3.
I would like to specify array sizes inside my code without polluting the global namespace with additional constants. I think it would be useful, especially in creating a library.
I can't find a solution to this problem. In case there isn't one, can you tell me the best practice to solve this problem? The only solutions I see are:
You can try something like this.
class <someclass>{
public:
static const int ARR_SIZE;
}
const int X::ARR_SIZE = <somevalue>;
since the variable is class scope, you wouldn't pollute the global namespace. alternatively you can create a namespace your own and define the static const variable inside of it such as
namespace <somename>{
static const int ARR_SIZE = <somevalue>;
// other definitions.
}
in this case the const variable read-only and accessible inside the namespace and can be accessed through::ARR_SIZE outside the namespace.
