VS Code advancedfunctions详解

1. advancedfunctionsoverview

VS Codeproviding了许 many advancedfunctions, 这些functions可以helping你更 high 效地forDevelopment. 本页面将介绍VS Code 一些coreadvancedfunctions, including:

• many 光标编辑
• commands面板advanced用法
• task and 构建system
• 远程Development
• containersDevelopment
• WSLDevelopment
• scaleDevelopment
• debugadvancedfunctions
• performanceoptimization

2. many 光标编辑

many 光标编辑 is VS Code 一项强 big functions, 允许你同时 in many 个位置for编辑.

2.1 basic many 光标operation

• 按住Alt键并点击鼠标: 添加 many 个光标
• Ctrl+Alt+Up/Down: in on 方/ under 方添加光标
• Ctrl+Shift+L: 选择所 has 匹配项并添加光标
• Ctrl+D: 选择 under 一个匹配项
• Ctrl+K+Ctrl+D: 跳过当 before 匹配项, 选择 under 一个
• Esc: 取消所 has many 光标

2.2 many 光标编辑case

// 原始code
const name1 = "Alice";
const name2 = "Bob";
const name3 = "Charlie";

// using many 光标编辑 fast 速modify
const name1 = { value: "Alice" };
const name2 = { value: "Bob" };
const name3 = { value: "Charlie" };

3. commands面板advanced用法

commands面板 is VS Code corefunctions之一, providing了访问几乎所 has VS Codefunctions 方式.

3.1 commands面板 fast 捷键

• Ctrl+Shift+P: 打开commands面板
• Ctrl+P: fast 速打开file
• Ctrl+Shift+O: in 当 before filein fast 速跳转符号
• Ctrl+T: in 所 has filein fast 速跳转符号

3.2 commands面板techniques

• in commands面板in输入"?"查看可用commands
• using"@" in 当 before filein跳转符号
• using"#" in 所 has filein搜索符号
• using">"执行commands
• using":"跳转 to 行号

4. task and 构建system

VS Code tasksystem允许你 in 编辑器inrun构建, test and othercommands.

4.1 creationtask

1. 打开commands面板, run"task: configurationtask"commands
2. 选择要creation taskclass型 (such asnpm, Gulp, Gruntetc.)
3. VS Code会自动生成tasks.jsonconfigurationfile

4.2 tasks.jsonexample

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "npm",
            "script": "build",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "problemMatcher": ["$tsc"]
        },
        {
            "label": "test",
            "type": "npm",
            "script": "test",
            "group": {
                "kind": "test",
                "isDefault": true
            }
        }
    ]
}

4.3 runtask

usingCtrl+Shift+Brun构建task, or throughcommands面板run"task: runtask"commands.

5. 远程Development

VS Code 远程Developmentscale允许你 in 远程server, containers or WSLinforDevelopment, 就像 in 本地Development一样.

5.1 远程Developmentscalepackage

installation"Remote Development"scalepackage, 它package含以 under 三个scale:

• Remote - SSH: throughSSH连接 to 远程server
• Remote - Containers: in DockercontainersinDevelopment
• Remote - WSL: in Windows Subsystem for LinuxinDevelopment

5.2 SSH远程Development

1. installationRemote - SSHscale
2. 点击 left under 角 绿色远程指示器
3. 选择"Remote-SSH: Connect to Host..."
4. 输入SSH连接information, such asuser@hostname
5. VS Code会 in 远程server on installation必要 component, 然 after 连接

5.3 containersDevelopment

usingRemote - Containersscale, 你可以 in DockercontainersinforDevelopment, 确保一致 Developmentenvironment.

6. scaleDevelopment

VS Code scaleAPI允许你creation自定义scale, scaleVS Code functions.

6.1 开始scaleDevelopment

1. installationNode.js and npm
2. installationYeoman and VS Codescale生成器:

   npm install -g yo generator-code

3. run生成器:

   yo code

4. 按照提示选择scaleclass型 and configuration

6.2 scaleprojectstructure

my-extension/
├── src/                  # sourcescode
│   └── extension.ts      # scale入口file
├── package.json          # scaleconfiguration
├── tsconfig.json         # TypeScriptconfiguration
└── README.md             # scale说明

6.3 debugscale

in VS Codein按F5可以启动scaledebugsession, VS Code会打开一个 new 窗口并加载你 scale.

7. debugadvancedfunctions

VS Code debugfunctionsproviding了许 many advanced features, helping你更 has 效地debugcode.

7.1 debugconfiguration

in launch.jsonin可以configuration complex debug场景, such as:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Program",
            "type": "node",
            "request": "launch",
            "program": "${workspaceFolder}/app.js",
            "args": ["--port", "3000"],
            "env": {
                "NODE_ENV": "development"
            },
            "sourceMaps": true,
            "outFiles": ["${workspaceFolder}/dist/**/*.js"]
        }
    ]
}

7.2 debug控制台advanced用法

• usingdebugger;语句 in codein设置断点
• in debug控制台in执行JavaScript表达式
• usingwatch面板监视variable变化
• using调用栈面板查看function调用relationships

8. performanceoptimization

such as果VS Coderun缓 slow , 可以尝试以 under optimization措施:

8.1 scalemanagement

• 禁用不常用 scale
• 定期updatescale
• usingscalepackagemanagement相关scale

8.2 设置optimization

// optimization编辑器performance
"editor.largeFileOptimizations": true,
"editor.dragAndDrop": false,
"editor.quickSuggestions": {
    "other": false,
    "comments": false,
    "strings": false
},

// optimization搜索performance
"search.followSymlinks": false,
"search.maxResults": 200,

// optimizationfilesystem监视
"files.watcherExclude": {
    "**/.git/objects/**": true,
    "**/.git/subtree-cache/**": true,
    "**/node_modules/**": true,
    "**/dist/**": true
}

8.3 硬件加速

确保启用了硬件加速:

"window.titleBarStyle": "custom",
"disable-hardware-acceleration": false

9. 实践case: 远程DevelopmentNode.jsapplication

让我们through一个实践case来LearningVS Code 远程Developmentfunctions:

9.1 准备工作

• installationRemote - SSHscale
• 准备一台远程server, installationNode.js and Git
• configurationSSHkeyauthentication

9.2 连接 to 远程server

1. 点击 left under 角 绿色远程指示器
2. 选择"Remote-SSH: Connect to Host..."
3. 输入SSH连接information, such asuser@remote-server
4. 连接成功 after , VS Code会显示远程server 名称

9.3 in 远程server on Development

1. in 远程server on creation一个 new Table of Contents: mkdir node-app
2. usingVS Code打开该Table of Contents
3. 初始化Node.jsproject: npm init -y
4. installationExpress: npm install express
5. creationapp.jsfile:

const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => {
    res.send('Hello from remote server!');
});

app.listen(port, () => {
    console.log(`App listening at http://localhost:${port}`);
});

6. in VS Codein启动debug, 选择Node.jsenvironment
7. in 本地浏览器in访问http://remote-server-ip:3000
