Template Haskell is enabled by the -XTemplateHaskell GHC extension. This extension enables all the syntactic features further detailed in this section. The full details on Template Haskell are given by the user guide. Splices A splice is a new syntactic entity enabled by Template Haskell, writ...

First, add Fresco to your build.gradle as shown in the Remarks section: If you need additional features, like animated GIF or WebP support, you have to add the corresponding Fresco artifacts as well. Fresco needs to be initialized. You should only do this 1 time, so placing the initialization in y...

The autocomplete feature in the Google Places API for Android provides place predictions to user. While user types in the search box, autocomplete shows places according to user's queries. AutoCompleteActivity.java private TextView txtSelectedPlaceName; @Override protected void onCreate(@Nulla...

When accessing a non-static member of an object through a pointer to member, if the object does not actually contain the member denoted by the pointer, the behavior is undefined. (Such a pointer to member can be obtained through static_cast.) struct Base { int x; }; struct Derived : Base { int y; ...

List subList(int fromIndex, int toIndex) Here fromIndex is inclusive and toIndex is exclusive. List list = new ArrayList(); List list1 = list.subList(fromIndex,toIndex); If the list doesn't exist in the give range, it throws IndexOutofBoundException. What ever changes made on the list1 wi...

Often you want to match an expression only in specific places (leaving them untouched in others, that is). Consider the following sentence: An apple a day keeps the doctor away (I eat an apple everyday). Here the "apple" occurs twice which can be solved with so called backtracking cont...

The result of a reinterpret_cast from one function pointer type to another, or one function reference type to another, is unspecified. Example: int f(); auto fp = reinterpret_cast<int(*)(int)>(&f); // fp has unspecified value C++03 The result of a reinterpret_cast from one object poi...

Consider preceding is our function definition with optional arguments. private static double FindAreaWithOptional(int length, int width=56) { try { return (length * width); } catch (Exception) { thro...

Custom validation attributes can be created by deriving from the ValidationAttribute base class, then overriding virtual methods as needed. [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = false)] public class NotABananaAttribute : ValidationAttribute { public ov...

An easing causes some variable to change unevenly over a duration. "variable" must be able to be expressed as a number, and can represent a remarkable variety of things: an X-coordinate, a rectangle's width, an angle of rotation, the red component of an R,G,B color. anything that c...

Arrays are zero-based, that is the index always starts at 0 and ends with index array length minus 1. Thus the following code will not output the first element of the array and will output garbage for the final value that it prints. #include <stdio.h> int main(void) { int x = 0; ...

Less doesn't put any restrictions on the number of times the parent selector (&) can be used in a complex selector and so, we can use it more than once like in the below examples to select sibling elements without the need to repeat the selector. .demo { border: 1px solid black; /* add borde...

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...

Sometimes a poorly designed 3rd-party library will write unwanted diagnostics to System.out or System.err streams. The recommended solutions to this would be to either find a better library or (in the case of open source) fix the problem and contribute a patch to the developers. If the above solu...

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...
