When you have an input with well defined boundaries and are expecting more than one match in your string, you have two options: Using lazy quantifiers; Using a negated character class. Consider the following: You have a simple templating engine, you want to replace substrings like $[foo] whe...

In comparison to regular classes – case classes notation provides several benefits: All constructor arguments are public and can be accessed on initialized objects (normally this is not the case, as demonstrated here): case class Dog1(age: Int) val x = Dog1(18) println(x.age) // 18 (success!...

[^0-9a-zA-Z] This will match all characters that are neither numbers nor letters (alphanumerical characters). If the underscore character _ is also to be negated, the expression can be shortened to: [^\w] Or: \W In the following sentences: Hi, what's up? I can't wait for 2017!...

[^0-9] This will match all characters that are not ASCII digits. If Unicode digits are also to be negated, the following expression can be used, depending on your flavor/language settings: [^\d] This can be shortened to: \D You may need to enable Unicode character properties support expl...

Dynamic scoping means that variable lookups occur in the scope where a function is called, not where it is defined. $ x=3 $ func1 () { echo "in func1: $x"; } $ func2 () { local x=9; func1; } $ func2 in func1: 9 $ func1 in func1: 3 In a lexically scoped language, func1 would alway...

If you have an instance of a generic type but for some reason don't know the specific type, you might want to determine the generic arguments that were used to create this instance. Let's say someone created an instance of List<T> like that and passes it to a method: var myList = new List&lt...

SequenceEqual is used to compare two IEnumerable<T> sequences with each other. int[] a = new int[] {1, 2, 3}; int[] b = new int[] {1, 2, 3}; int[] c = new int[] {1, 3, 2}; bool returnsTrue = a.SequenceEqual(b); bool returnsFalse = a.SequenceEqual(c);
