Array

Operators and functions for working with arrays (arr type) are described here. arr.typename means that you can specify any type name but in the case of the binary operator this type must be the same in both arrays.

• bool( arr.typename a ) bool

• Join( arr.str a, str sep ) str

• Reverse( arr.typename a ) arr.typename

• Slice( arr.typename a, int start, int end ) arr.typename

• Sort( arr.str a ) arr.str

Operators

Operator	Result	Description
* arr.typename	int	Returns the number of elements in the array.
arr.typename ?	bool	Calls bool(arr.typename).
arr.typename = arr.typename	arr.typename	Assignment operator.
arr.typename &= arr.typename	arr.typename	Creates a clone of the array. The new variable will work with the same data set.
arr.typename += arr.typename	arr.typename	Adds items from one array to another.
arr.str += str	arr.str	Adds a string to an array of strings.
arr.int += int	arr.int	Adds an integer number to an array of integer numbers.
arr.bool += bool	arr.bool	Adds a Boolean value to an array of Boolean values.
arr.arr.typename += arr.typename	arr.arr.typename	Adds an array to an array of arrays.
arr.map.typename += map.typename	arr.map.typename	Adds a map to an array of maps.
arr.typename [ int ]	typename	Sets/gets an array value by index.

Functions

bool(arr.typename a) bool

The bool function returns false if the array is empty, otherwise, it returns true.

Join(arr.str a, str sep) str

The Join function joins strings of the array. The separator string sep is placed between strings in the resulting string.

Reverse( arr.typename a ) arr.typename

The Reverse function reverses the order of the elements in the array and returns this array.

Slice( arr.typename a, int start, int end ) arr.typename

The Slice function copies some consecutive elements from within an array. start is inclusive, while end is exclusive. The function returns the created array.

Sort(arr.str a) arr.str

The Sort function sorts an array of strings in increasing order and returns it.
