我找到了一些Vala的代码,它运行正常。 但是当我把它翻译成精灵时,却失败了。 所以,我的问题是什么是Genie的等效代码
$scope
我的代码:精灵
for (var i = 0 ; i < $scope.Permissions.length; i++) {
$scope['arr' + i] = $scope.Permissions[i];
}
console.log($scope.arr0, $scope.arr1);
错误消息:
int get_length<T> (T val) {
if (typeof(T) == typeof(string) ) {
return ((string)val).length;
} else {
GLib.error("Unable to handle type `%s'", typeof(T).name());
}
}
public static void main() {
var myString = "hello";
stdout.printf("%i\n", get_length<string>(myString));
}
更新
代码有效。
def get_length of T (val: T): int
if typeof(T) == typeof(string)
return ((string)val).length
else
pass
init
var s = "hello";
stdout.printf("%i", get_length of string (s))
但如果我想要返回值
我试试
main.gs:2.16-2.17: error: syntax error, expected `(' but got `of' with previous identifier
def get_length of T (val: T): int
^^
和错误消息:
init
printx of int (123)
printx (456)
printx ("HELLO")
def printx (i: T) of T
case typeof(T)
when 64 // typeof(string)
stdout.printf ("%s\n", (string)i)
when 24 // typeof(int)
stdout.printf ("%i\n", (int)i)
并尝试
def doubleit (i: T): T of T
错误消息:
2015-06-29_generic_func.gs:13.27-13.27: error: The type name `T' could not be found
def doubleit (i: T): T of T
^
2015-06-29_generic_func.gs:13.22-13.27: error: The type name `T' could not be found
def doubleit (i: T): T of T
^^^^^^
2015-06-29_generic_func.gs:13.18-13.18: error: The type name `T' could not be found
def doubleit (i: T): T of T

Compilation failed: 3 error(s), 0 warning(s)
此代码适用于Vala:
def doubleit (i: T) of T : T
