Question

我目前正在使用ChaiScript版本6.0.0和Visual Studio 2017。

在我的C ++中，我正在从脚本文件中检索对函数on_init()的引用，并执行它。 ChaiScript对象是使用默认/空构造函数构造的。该函数如下所示：

def on_init() {
  use("scripts/test.chai");
}

＆＃34; scripts / test.chai＆＃34;的内容看起来像这样：

class A {
  def A() {
    print("Created an instance of A!");
  }
}

我的文件结构如下：

bin
   \
   | my_executable.exe
   | scripts
           \
           | main_menu.chai
           | test.chai

执行上面显示的on_init()函数时，控制台会输出以下消息：

Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use" Error: "Can not find object: use"

提供＆＃34; usepaths＆＃34;在构造ChaiScript对象时导致相同的情况。

我已尝试use("test.chai")以及use("scripts/test.chai")，两者都会产生相同的消息。

我没有在构建ChaiScript对象时提供任何chaiscript::Options枚举，因此它应该使用默认值（它似乎包含External_Scripts以及Load_Modules）。

我正在编译ChaiScript，禁用线程安全。

我在运行此脚本的任何其他内置函数时没有任何问题，包括我正在检索的其他函数（进入C ++），方法与此相同。

如果还有其他信息，请与我们联系。

我使用＆＃34;使用＆＃34;功能不正确？

编辑：当我写下这些内容时，一定非常高，但我会把它留在那里只是因为我很惊讶我甚至可以想出来。

真正的答案是您必须明确地将chaiscript::Options::External_Scripts传递给ChaiScript构造函数才能启用文件加载功能。

我是这样做的：

class ChaiPlugin
{
public:
    /* stuff */
private:
    chaiscript::ChaiScript chai = { {}, {}, { chaiscript::Options::External_Scripts } };
};

use仅用于进行调试。

来自unittests/boxed_cast_test.cpp：

template<typename T>
void use(T){}

我相信你要找的是usefile("scripts/test.chai")。

错误：＆＃34;无法找到对象：使用＆＃34;
