VSCode 扩展位置变量 [英] VSCode extensions location variable

问题描述

在我正在编写的扩展中，我想重新定义工作区中的现有设置以指向我与扩展一起打包的脚本.例如，在 Mac 上，此脚本位于 ~/.vscode/extensions/publisher.name.version/script 中.

In an extension I am writing, I want to redefine an existing setting in the workspace to point at a script I am packaging with the extension. On a mac this script lives in ~/.vscode/extensions/publisher.name.version/script for example.

如果我假设这是扩展所在的位置，那么在我的 activate 函数中，我可以使用

If I assume that this is where the extension lives then in my activate function I can update this value using

export async function activate(context: vscode.ExtensionContext) {
  const home = process.env.HOME;
  const execLocation = home + "/.vscode/extensions/publisher.name.version/script";
  ...

然后更新工作区设置.

但是 - 我想访问本地安装的扩展位置，以及我的扩展的 ID 和版本 - 我在 VSCode 中找不到正确的设置来执行此操作.如果有人知道正确的环境变量以便我可以访问它们，我将不胜感激.

However - I would like to access the locally installed extensions location, together with the id and version of my extension - I cannot find the correct setting in VSCode to do this. I would be very grateful if someone knew the correct environment variable so I could access them.

我知道可以使用选项 --extensionHomePath 从命令行调用代码 - 我不确定如何以编程方式访问此变量.

I know it is possible to call code from the command line with the option --extensionHomePath - I am not sure how to access this variable programmatically.

此外，我不确定如何从 context 参数中找到版本、发布者和名称 - 显然我从 package.json 文件中知道这些，但它会是如果可能的话，很高兴能够以编程方式访问它们.

Also I am not sure how to find the version, publisher and name from the context parameter - obviously I know these from the package.json file but it would be nice to be able to access them programmatically if possible.

推荐答案

您可以通过 ExtensionContext.
此方法为您提供给定相对路径(关于您的项目根目录)的资源的绝对路径.

You can get that information by the asAbsolutePath() method of the ExtensionContext.
This method gets you the absolute path of a resource for a given relative path (regarding your project root).

因此我建议您将代码更改为以下内容:

Therefore I suggest you to change your code to the following:

export async function activate(context: vscode.ExtensionContext) {
    const execLocation = context.asAbsolutePath("script");
    console.log("Absolute exec location: " + execLocation);
