如何访问 VSCode 创建的 AST [英] How can I access the AST that VSCode creates

问题描述

我为 UI5 JavaScript 编写了一个 VSCode 扩展.最缺少的功能是为 UI5 提供 IntelliSense.使用 UI5 类型它会起作用，但不是全部.

I write a VSCode Extension for UI5 JavaScript. The most missing Feature is to have IntelliSense for UI5. Using UI5 typings it will work but not in all.

这有效:

var testvar1 = new sap.m.Button();

现在我可以在 testvar1 的 VSCode 中使用 IntelliSense.

Now i can use IntelliSense in VSCode in the testvar1.

问题例如:

sap.ui.define([
  "sap/ui/core/mvc/Controller"
  ], 
  function (Controller) {
    "use strict";
    return Controller.extend("", {

    });
  });

本例中函数中有一个Controller变量，这个变量是之前用Namespace定义的.我现在搜索在我的扩展中使用命名空间分配这个变量的可能性.我知道这可以在 AST 中完成，但我现在知道如何访问 AST 以进行设置:

In this case there is a Controller variable in the function, this variable is defined with the Namespace before. I search now for a possibility to assign this variable in my Extension with the Namespace. I know this can be done in the AST but i have now idear how to get access to the AST to set:

Controller = sap.ui.core.mvc.Controller

目标是现在在变量控制器中拥有完整的智能感知

The goal is to have the full IntelliSense now in the variable Controller

我希望到目前为止我想要什么.

I hope it is clear what i want, so far.

推荐答案

如果你只需要给 Controller 一个类型，请尝试使用 jsdocs:

If you only need to give a type to Controller, try using jsdocs:

sap.ui.define([
  "sap/ui/core/mvc/Controller"
  ], 
  function (/** @type {sap.m.Controller} */ Controller) {
     ...
  });

要回答原始问题，您可以使用 TypeScript 服务器插件.这不是微不足道的，所以我会尽量避免这样做，除非你真的需要

To answer the original question, you can access/modify the AST with a TypeScript server plugin. This is not trivial so I would try to avoid doing this unless you really need to
