The following snippet replaces all Attributes called PreviousAttribute by an Attribute called ReplacementAttribute for an entire solution. The sample manually searches the Syntax tree and replaces all affected nodes. static async Task<bool> ModifySolution(string solutionPath) { ...

The following snippet replaces all Attributes called "PreviousAttribute" by an Attribute called "ReplacementAttribute" for an entire solution. The sample manually uses a SyntaxRewriter to exchange the attributes. /// <summary> /// The CSharpSyntaxRewriter allows to rewrit...

C11 The function specifier _Noreturn was introduced in C11. The header <stdnoreturn.h> provides a macro noreturn which expands to _Noreturn. So using _Noreturn or noreturn from <stdnoreturn.h> is fine and equivalent. A function that's declared with _Noreturn (or noreturn) is not allowe...

Function calls as f(a) always imply a sequence point between the evaluation of the arguments and the designator (here f and a) and the actual call. If two such calls are unsequenced, the two function calls are indeterminately sequenced, that is, one is executed before the other, and order is unspeci...

Sometimes you may need to convert a Set to an array, for example to be able to use Array.prototype methods like .filter(). In order to do so, use Array.from() or destructuring-assignment: var mySet = new Set([1, 2, 3, 4]); //use Array.from const myArray = Array.from(mySet); //use destructuring-a...

There are no build-in methods for intersection and difference in Sets, but you can still achieve that but converting them to arrays, filtering, and converting back to Sets: var set1 = new Set([1, 2, 3, 4]), set2 = new Set([3, 4, 5, 6]); const intersection = new Set(Array.from(set1).filter(x...

You can use a simple for-of loop to iterate a Set: const mySet = new Set([1, 2, 3]); for (const value of mySet) { console.log(value); // logs 1, 2 and 3 } When iterating over a set, it will always return values in the order they were first added to the set. For example: const set = new S...

To generalize type_trait creation:based on SFINAE there are experimental traits detected_or, detected_t, is_detected. With template parameters typename Default, template <typename...> Op and typename ... Args: is_detected: alias of std::true_type or std::false_type depending of the validi...

Classes, structs, enums and all their methods are internal by default. This means they can be only accessed from the same module. The test cases are in a different target an this means they are in a different module. To be able to access the method you want to test, you need to import the module to ...

Some attributes are directly accessible as properties of the element (e.g. alt, href, id, title and value). document.querySelector("a").href = "#top"; Other attributes, including data-attributes can be set as follows: document.querySelector("a").setAttribute("...

This is an advanced example. You can use variant for light weight type erasure. template<class F> struct pseudo_method { F f; // enable C++17 class type deduction: pseudo_method( F&& fin ):f(std::move(fin)) {} // Koenig lookup operator->*, as this is a pseudo-method...
