Instance Method Detail

def +(other : ArrayLiteral) : ArrayLiteral #

Similar to `Array#+`.

def <<(value : ASTNode) : ArrayLiteral #

Similar to `Array#<<`.

def [](index : NumberLiteral) : ASTNode #

Similar to `Array#[]`, but returns `NilLiteral` on out of bounds.

def []=(index : NumberLiteral, value : ASTNode) #

Similar to `Array#[]=`.

def all?(&) : BoolLiteral #

Similar to `Enumerable#all?`

def any?(&) : BoolLiteral #

Similar to `Enumerable#any?`

def clear : ArrayLiteral #

Similar to `Array#clear`

def empty? : BoolLiteral #

Similar to `Array#empty?`

def find(&) : ASTNode | NilLiteral #

Similar to `Enumerable#find`

def first : ASTNode | NilLiteral #

Similar to `Array#first`, but returns a `NilLiteral` if the array is empty.

def includes?(node : ASTNode) : BoolLiteral #

Similar to `Enumerable#includes?(obj)`.

def join(separator) : StringLiteral #

Similar to `Enumerable#join`

def last : ASTNode | NilLiteral #

Similar to `Array#last`, but returns a `NilLiteral` if the array is empty.

def map(&) : ArrayLiteral #

Similar to `Enumerable#map`

def map_with_index(&) : ArrayLiteral #

Similar to `Enumerable#map_with_index`

def of : ASTNode | Nop #

Returns the type specified at the end of the array literal, if any.

This refers to the part after brackets in `[] of String`.

def push(value : ASTNode) : ArrayLiteral #

Similar to `Array#push`.

def reduce(memo : ASTNode, &) : ASTNode #

Similar to `Enumerable#reduce`

def reduce(&) : ASTNode #

Similar to `Enumerable#reduce`

def reject(&) : ArrayLiteral #

Similar to `Enumerable#reject`

def select(&) : ArrayLiteral #

Similar to `Enumerable#select`

def shuffle : ArrayLiteral #

Similar to `Array#shuffle`

def size : NumberLiteral #

Similar to `Array#size`

def sort : ArrayLiteral #

Similar to `Array#sort`

def sort_by(&) : ArrayLiteral #

Similar to `Array#sort_by`

def splat(trailing_string : StringLiteral = nil) : MacroId #

Returns a `MacroId` with all of this array's elements joined by commas.

If trailing_string is given, it will be appended to the result unless this array is empty. This lets you splat an array and optionally write a trailing comma if needed.

def type : Path | Nop #

Returns the type that receives the items of the array.

This refers to the part before brackets in `MyArray{1, 2, 3}`

def uniq : ArrayLiteral #

Similar to `Array#uniq`

def unshift(value : ASTNode) : ArrayLiteral #

Similar to `Array#unshift`.
