Haskell Wiki has an example of a non-parametric parameter of a type function:
type family Inspect x
type instance Inspect Age = Int
type instance Inspect Int = Bool
Here x is non-parametric because to determine the outcome of applying Inspect to a type argument, the type function must insp...
An example of a parametric parameter of a type function:
data List a = Nil | Cons a (List a)
type family DoNotInspect x
type instance DoNotInspect x = List x
Here x is parametric because to determine the outcome of applying DoNotInspect to a type argument, the type function do not need to in...
The example I'm going to discuss assumes you have a Docker installation that works in your system and a basic understanding of how to work with Node.js . If you are aware of how you must work with Docker , it should be evident that Node.js framework need not be installed on your system, rather we wo...
Our demo app consists of a scoreboard. The score model is an immutable record. The scoreboard events are contained in a Union Type.
namespace Score.Model
type Score = { ScoreA: int ; ScoreB: int }
type ScoringEvent = IncA | DecA | IncB | DecB | NewGame
Changes are propagated by listening...
The core types in the Gjallarhorn library implement IObservable<'a>, which will make the implementation look familiar (remember the EventStream property from the FSharp.ViewModule example). The only real change to our model is the order of the arguments of the update function. Also, we now use...

The typical usage is with CSV-type files, where each line consists of fields separated by a delimiter, specified by the option -d. The default delimiter is the TAB character. Suppose you have a data file data.txt with lines like
0 0 755 1482941948.8024
102 33 4755 1240562224.3205
1003 1 644 12199...
You cannot have more than one delimiter: if you specify something like -d ",;:", some implementations will use only the first character as a delimiter (in this case, the comma.) Other implementations (e.g. GNU cut) will give you an error message.
$ cut -d ",;:" -f2 <<<&...
$ cut -d, -f1,3 <<<"a,,b,c,d,e"
a,b
is rather obvious, but with space-delimited strings it might be less obvious to some
$ cut -d ' ' -f1,3 <<<"a b c d e"
a b
cut cannot be used to parse arguments as the shell and other programs do.
There is no way to protect the delimiter. Spreadsheets and similar CSV-handling software usually can recognize a text-quoting character which makes it possible to define strings containing a delimiter. With cut you cannot.
$ cut -d, -f3 <<<'John,Smith,"1, Main Street"'
"1
...
You can only extract portions of lines, not reorder or repeat fields.
$ cut -d, -f2,1 <<<'John,Smith,USA' ## Just like -f1,2
John,Smith
$ cut -d, -f2,2 <<<'John,Smith,USA' ## Just like -f2
Smith
The EntityDamage event is thrown when an Entity is damaged.
EntityDamageEvent
@EventHandler
public void onEntityDamage(EntityDamageEvent e) {
DamageCause cause = e.getCause(); //Get the event DamageCause
double rawDamage = e.getDamage(); //Returns the damage before any calculation...
One of the main advantage of std::array as compared to C style array is that we can check the size of the array using size() member function
int main() {
std::array<int, 3> arr = { 1, 2, 3 };
cout << arr.size() << endl;
}
