Question

我想在运行时查看我的.ts文件，并获取有关文件中哪些类，它具有哪些功能，哪些属性以及它们是公共还是私有的信息。

在actionscript3中，我曾经使用“describeType”，它以XML格式返回此信息。有人知道用打字稿获取这些信息的方法吗？

是否有工具可以解析任何文件类型的jsdoc并返回有关该文件类型的信息？

Answer 1

由于你想处理文件，我不理解“在运行时”的要求。

除此之外，如果您只想使用TS分析TS代码，您可以使用TypeScript语言服务，它们具有支持TypeScript IDE所需的所有API，所有这些都是用TypeScript编写的。在这个特定的例子中，languageService.getScriptLexicalStructure(file)应该可以解决问题。

如果您想从命令行执行此操作，或想查看使用语言服务的示例，可以尝试https://github.com/clausreinke/typescript-tools

$ cat reflection.ts
module foo{
    export class A{
        public x1:number = 10;
        public x2 = 20;

        public s1: string = "";
        constructor(public x = true) {}
    }
}

function listProperties(o, isClass?) {
        var props = [];
        console.log("name:",o["name"]);
        var tmp = isClass ? new o : o;
        for (var p in tmp)
          console.log(p,typeof tmp[p]);
}
listProperties(foo.A,true);

Answer 2

没有TypeScript反射API，但您可以使用ES3 JavaScript API！你应该看看这些功能：

Typescript等同于actionscript3的describeType
