Instance Method Detail
def double_splat(trailing_string : StringLiteral = nil) : MacroIdSource
Returns a MacroId
with all of this hash elements joined by commas-
If trailing_string is given, it will be appended to the result unless this hash is empty- This lets you splat a hash and optionally write a trailing comma if needed-
def empty? : BoolLiteralSource
Similar to Hash#empty?
def keys : ArrayLiteralSource
Similar to Hash#keys
def map : ArrayLiteralSource
Similar to Hash#map
def size : NumberLiteralSource
Similar to Hash#size
def to_a : Crystal::Macros::ArrayLiteral(TupleLiteral)Source
Similar to Hash#to_a
def type : Path | NopSource
Returns the type that receives the items of the array.
This refers to the part before brackets in MyHash{'a' => 1, 'b' => 2}
def values : ArrayLiteralSource
Similar to Hash#values
