The widely used combination of tic and toc can provide a rough idea of the execution time of a function or code snippets. For comparing several functions it shouldn't be used. Why? It is almost impossible to provide equal conditions for all code snippets to compare within a script using above solu...

GHCi uses a configuration file in ~/.ghci. A configuration file consists of a sequence of commands which GHCi will execute on startup. $ echo ":set prompt \"foo> \"" > ~/.ghci $ ghci GHCi, version 8.0.1: http://www.haskell.org/ghc/ :? for help Loaded GHCi configuration...

The :l or :load command type-checks and loads a file. $ echo "f = putStrLn \"example\"" > example.hs $ ghci GHCi, version 8.0.1: http://www.haskell.org/ghc/ :? for help ghci> :l example.hs [1 of 1] Compiling Main ( example.hs, interpreted ) Ok, modules ...

Lets suppose you have 2 Lists A and B, and you want to remove from B all the elements that you have in A the method in this case is List.removeAll(Collection c); #Example: public static void main(String[] args) { List<Integer> numbersA = new ArrayList<>(); List<Intege...

Reverse elements within a tuple colors = "red", "green", "blue" rev = colors[::-1] # rev: ("blue", "green", "red") colors = rev # colors: ("blue", "green", "red") Or using reversed (reversed gives an it...

def str = 'Single quoted string' assert str instanceof String

def str = "Double quoted string" assert str instanceof String

def param = 'string' def str = "Double quoted ${param}" assert str instanceof GString assert str == 'Double quoted string' The parameter is by default resolved eagerly, this means this applies: def param = 'string' def str = "Double quoted ${param}" param = 'another stri...

def param = 'string' def str = """ multiline $param """ assert str instanceof GString assert str.readLines().size() == 3 assert str == ''' multiline string '''

You can apply the same change shown in the Index Settings example to all existing indices with one request, or even a subset of them: PUT /*/_settings { "index": { "indexing.slowlog.threshold.index.warn": "1s", "search.slowlog.threshold": { ...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. You can use the _cat APIs to get a human readable, tabular output for various reasons. GET /_cat/health <1> _cat/health has existed since Elasticsearch 1.x, but here is an example of its output...

Example uses basic HTTP syntax. Any <#> in the example should be removed when copying it. Like most _cat APIs in Elasticsearch, the API selectively responds with a default set of fields. However, other fields exist from the API if you want them: GET /_cat/health?help <1> ?help cau...

Let's say, we have a simple LoginForm class with rules() method (used in login page as framework template): class LoginForm { public $email; public $rememberMe; public $password; /* rules() method returns an array with what each field has as a requirement. * Login form u...
