在 Typescript 中使用 FileSystemWatcher(Visual Studio Code 扩展) [英] Using FileSystemWatcher in Typescript (Visual Studio Code extension)

问题描述

我是 TypeScript 和 Visual Studio Code 的新手，想为 Visual Studio Code 开发一个插件.但是我被 FileSystemWatcher 触发的事件挂了.激活时，在我的扩展程序中，我创建了一个 FileSystemWatcher 并希望它通知我所有 TypeScript 文件的更改.这就是我迄今为止一直在做的:

I am new to TypeScript and Visual Studio Code and want to develop a plugin for Visual Studio Code. But I am hung up with an event fired by a FileSystemWatcher. On activation, in my extension I create a FileSystemWatcher and want it to inform me about changes to all TypeScript files. This is what I've been doing so far:

var watcher = vscode.workspace.createFileSystemWatcher("*.ts"); //glob search string
watcher.ignoreChangeEvents = false;

watcher.onDidChange(() => {
 vscode.window.showInformationMessage("change applied!"); //In my opinion this should be called
});

我可以在调试中看到观察者已创建，但它从未对事件做出反应.有人能解释一下如何正确使用这个回调吗?

I can see in debug that the watcher is created, but it never reacts to the event. Can someone explain how to use this callback the right way?

这是一个可通过函数访问的事件:

This is an event accessible via a function:

watcher.onDidChange

推荐答案

On

var watcher = vscode.workspace.createFileSystemWatcher("*.ts");

请使用 "**/*.ts 而不是 "*.ts".
