Primitives

Listed below are all the different types that Loop has out of the box. All the types have an explanations and some examples.

Integer#

An integer is a primitive value that can be up to 64bits in length. You can define an integer like this:

integer := 10; // Positive integerinteger := -200; // Negative integer

Methods#

Convert to string#

// Returns 123 to string123.to_string()

Booleans#

A boolean is a primitive value that can either be true or false. You can define a boolean like this:

boolean := trueboolean := false

Methods#

Convert to integer#

This method will cause an exception if the string is unable to be converted.

true = 1
false = 0

// Converts the boolean true to 1boolean :trueboolean.to_int()

Strings#

A string is a sequence of characters inside "'s. You can define a string like this:

str := "hello"       // A single wordstr := "hello world" // Multiple words

Methods#

Convert to integer#

This method will cause an exception if the string is unable to be converted.

// Converts the string "123" to integer"123".to_int()

Null#

Loop only has one primitive indicating the absence of a value. Which is "null", a Null value indicates "not a value". You can define something to be null like this:

has_nothing := null

The Null primitive will result in "false", for example.

has_nothing := null
if (has_nothing) {  // Will not print  println("Hi!")} else {  // This will print  println("Bye!")}

Arrays#

An array is a list of values. Arrays are automatically dynamic but can only have one type in them.

array := [100, 50, 300]
// Wont work!array := ["hello", "world", "!"]

Accessing Arrays#

Accessing an array is simple. You use the index operators (square brackets []). Let's take the previous example and use it here to access the "100" value in the sub array.

array := [[100], [300]]value := array[0][0] // sets the value of "value" to 100

Or a simpler array:

array := [100, 200, 300]value := array[1] // sets the value of "value" to 200

Methods#

array.add(element1, element2, ...)#

// Initialize new arrayx := [0, 1]
// Add 2 to the arrayx.add(2)
// Array will now be [0, 1, 2]x
// It's also possible to add multiple to the array at oncex.add(3, 4, 5)
// Array will now be [0, 1, 2, 3, 4, 5]x

array.remove(index: Integer)#

x := [0, 1, 2]
// Removes index 0 from the arrayx.remove(0)
// Removes index 1 from the arrayx.remove(1)
// Array will now be [1]x

array.length()#

// Initialize array with 3 elementsx := [0, 1, 2]
// Returns 3x.length()

Hashmaps#

A hashmap is a way to bind keys to values. The key is limited in what types they can be, currently these types are allowed as keys:

String
Integer
Boolean

Hashmap keys are required to be unique, they can have spaces as well (if you're using a string as key).

Creating a hashmap is easy and might seem familiar if you've used other languages before. An example with a few sample key value pairs is as follows:

hashmap := {  "key1": "value",  "key2": "value"}

Important: the key and value types can only be specified once, and require to be the same afterwards.
