VS Code 中的偵錯

本指南將引導您設定 VS Code，以偵錯 Tauri 應用程式的核心程序。

先決條件

安裝 vscode-lldb 擴充功能。

設定 launch.json

建立一個 .vscode/launch.json 檔案，並將以下 JSON 內容貼到其中

.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"
    }
  ]
}

這會直接使用 cargo 來建置 Rust 應用程式，並在開發和生產模式中載入它。

請注意，它不使用 Tauri CLI，因此不會執行獨有的 CLI 功能。beforeDevCommand 和 beforeBuildCommand 腳本必須事先執行，或在 preLaunchTask 欄位中設定為一個工作。以下是一個範例 .vscode/tasks.json 檔案，其中包含兩個工作，一個是執行開發伺服器的 beforeDevCommand，另一個是 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.dev.org.tw/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"]
    }
  ]
}

現在，您可以在 src-tauri/src/main.rs 或任何其他 Rust 檔案中設定中斷點，並按下 F5 開始除錯。
