ReturnStmtCallStackUnwind mixin

Normal lua runtime behavior implementation for ReturnStmt.

Unwind the callstack on return by throwing a special exception LuaReturnValueException with the value to return. This value is unpacked correctly by the try-catch handler in function call statements by design.

Methods

addDiagnostic(String info) → void
inherited
addError(String err) → void
inherited
addWarning(String warn) → void
inherited
callLuaFunction(LuaObject obj, {List<Object?> args = const []}) → LuaObject?
Given a callable lua obj and a list of args, configure a new scope with the provided args as parameters based on the LuaObject.funcDef record. Args exceeding the parameter list will be dropped. Any remaining parameters will be filled by LuaObject.nil values. Any exceptions are caught and tracked for the trace back later. The scope is popped and any return result LuaObject is returned.

debugSetPath(String? path) → void
inherited
defGlobal(LuaObject value) → LuaObject
inherited
defLocal(LuaObject value) → LuaObject
inherited
findOnSelf(String field, {Object? or}) → LuaObject?
First finds field inside object "self" in Scope. If neither can be found, or is returned cast toLua. If or is not provided, null is returned.
inherited
findVar(String id) → LuaObject?
inherited
findVarArgs() → List<LuaObject>?
inherited
lineInfo(Token token) → String
inherited
lineTag(Token token) → String
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
popScope() → void
inherited
pushScope({LuaObject? context}) → void
inherited
tokenId(Token token, {String? prefix}) → String
inherited
toString() → String
A string representation of this object.
