class Crystal::Macros::Path
Overview
A Path to a constant or type, like Foo or Foo::Bar::Baz.
Defined in:
compiler/crystal/macros.crInstance Method Summary
- #global : BoolLiteral
Returns
trueif this is a global path (starts with::)DEPRECATED Use
#global?instead - #global? : BoolLiteral
Returns
trueif this is a global path (starts with::) - #names : ArrayLiteral(MacroId)
Returns an array with each separate part of this path.
- #resolve : ASTNode
Resolves this path to a
TypeNodeif it denotes a type, to the value of a constant if it denotes a constant, or otherwise gives a compile-time error. - #resolve? : ASTNode | NilLiteral
Resolves this path to a
TypeNodeif it denotes a type, to the value of a constant if it denotes a constant, or otherwise returns aNilLiteral. - #types : ArrayLiteral(ASTNode)
Returns this path inside an array literal.

def global : BoolLiteralSource
Returns true if this is a global path (starts with ::)
DEPRECATED Use #global? instead
def global? : BoolLiteralSource
Returns true if this is a global path (starts with ::)
def names : ArrayLiteral(MacroId)Source
Returns an array with each separate part of this path.
def resolve : ASTNodeSource
Resolves this path to a TypeNode if it denotes a type, to the value of a constant if it denotes a constant, or otherwise gives a compile-time error.
def resolve? : ASTNode | NilLiteralSource
Resolves this path to a TypeNode if it denotes a type, to the value of a constant if it denotes a constant, or otherwise returns a NilLiteral.
def types : ArrayLiteral(ASTNode)Source
Returns this path inside an array literal. This method exists so you can call #types on the type of a type declaration and get all types, whether it's a Generic, Path or Union.
