在 VS Code 中调试

本指南将指导你设置 VS Code 以调试 Tauri 应用程序的核心进程。

先决条件

安装 vscode-lldb 扩展。

配置 launch.json

创建一个 .vscode/launch.json 文件，并将以下 JSON 内容粘贴到其中

.vscode/launch.json

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "type": "lldb",
      "request": "launch",
      "name": "Tauri Development Debug",
      "cargo": {
        "args": [
          "build",
          "--manifest-path=./src-tauri/Cargo.toml",
          "--no-default-features"
        ]
      },
      // task for the `beforeDevCommand` if used, must be configured in `.vscode/tasks.json`
      "preLaunchTask": "ui:dev"
    },
    {
      "type": "lldb",
      "request": "launch",
      "name": "Tauri Production Debug",
      "cargo": {
        "args": ["build", "--release", "--manifest-path=./src-tauri/Cargo.toml"]
      },
      // task for the `beforeBuildCommand` if used, must be configured in `.vscode/tasks.json`
      "preLaunchTask": "ui:build"
    }
  ]
}

这直接使用 cargo 构建 Rust 应用程序，并以开发和生产模式加载它。

请注意，它不使用 Tauri CLI，因此不会执行独有的 CLI 功能。beforeDevCommand 和 beforeBuildCommand 脚本必须事先执行或在 preLaunchTask 字段中配置为任务。以下是示例 .vscode/tasks.json 文件，其中有两个任务，一个用于生成开发服务器的 beforeDevCommand，另一个用于 beforeBuildCommand

.vscode/tasks.json

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "ui:dev",
      "type": "shell",
      // `dev` keeps running in the background
      // ideally you should also configure a `problemMatcher`
      // see https://vscode.js.cn/docs/editor/tasks#_can-a-background-task-be-used-as-a-prelaunchtask-in-launchjson
      "isBackground": true,
      // change this to your `beforeDevCommand`:
      "command": "yarn",
      "args": ["dev"]
    },
    {
      "label": "ui:build",
      "type": "shell",
      // change this to your `beforeBuildCommand`:
      "command": "yarn",
      "args": ["build"]
    }
  ]
}

现在，你可以在 src-tauri/src/main.rs 或任何其他 Rust 文件中设置断点，并按 F5 开始调试。
