如何在Sublime文本中使用自動完成？

<p>Sublime Text的自動補全功能可通過以下步驟啟用並自定義以提升編碼效率：1. 啟用基礎自動補全，確保設置中包含“auto_complete”: true，並使用快捷鍵Ctrl Space（Windows/Linux）或Cmd Space（Mac）手動觸發建議列表；2. 自定義補全來源，通過修改“auto_complete_use_tags”和“auto_complete_with_all_tabs”設置控制建議來源，同時可調整“auto_complete_delay”設定彈出延遲；3. 使用代碼片段實現智能補全，創建自定義快捷方式如輸入forloop後按Tab鍵插入完整循環結構，確保片段作用域正確以避免錯誤插入。合理配置後，Sublime Text將成為高效的編碼輔助工具。</p> <p> Sublime Text has a built-in auto-completion feature that can help speed up your coding by suggesting variable names, functions, and even custom snippets as you type. It's not overly flashy, but it works well if you know how to use it properly.</p> <h3 id="Enable-Basic-Auto-Completion"> Enable Basic Auto-Completion</h3> <p> By default, Sublime Text offers basic auto-complete suggestions based on what's already in your current file or project. To make sure it's working:</p> <ul> <li> Start typing something like a variable name or function.</li> <li> Press <code>Ctrl Space</code> (Windows/Linux) or <code>Cmd Space</code> (Mac) to manually trigger the suggestion list.</li> </ul> <p> You'll notice that as you type more, Sublime gets better at guessing what you want — especially if those words have appeared before in your file.</p> <p> If you're not seeing any suggestions, go to <strong>Preferences > Settings</strong> and check that this line is present:</p><pre class='brush:php;toolbar:false;'> "auto_complete": true</pre><p> Also, you can adjust how long to wait before auto-complete pops up using the <code>auto_complete_delay</code> setting (measured in milliseconds).</p><h3 id="Customize-Auto-Complete-Sources"> Customize Auto-Complete Sources</h3><p> Sublime Text pulls suggestions from a few different places. You can tweak where it looks for suggestions by editing your settings:</p><ul><li> Words from open files ( <code>"auto_complete_use_tags"</code> : usually enabled by default)</li><li> Words from the current file ( <code>"auto_complete_with_all_tabs"</code> : useful when working across multiple files)</li></ul><p> To fine-tune these behaviors, add or modify the following in your user settings:</p><pre class='brush:php;toolbar:false;'> { "auto_complete": true, "auto_complete_selector": "source, text", "auto_complete_triggers": [ {"selector": "text.html.basic", "characters": "<"} ] }</pre><p> This setup means auto-complete will work in most code files and also kick in after typing <code><</code> in HTML files, which is handy for tag suggestions.</p><h3 id="Use-Snippets-for-Smarter-Completion"> Use Snippets for Smarter Completion</h3><p> Auto-complete isn't just about guessing what you're typing — you can define your own shortcuts using <strong>snippets</strong> .</p><p> For example, create a snippet that inserts a full <code>for</code> loop when you type <code>forloop</code> and press <code>Tab</code> . Here's a simple one for JavaScript:</p><pre class='brush:php;toolbar:false;'> <snippet> <content><![CDATA[ for (let i = 0; i < ${1:array}.length; i ) { ${2:// code here} } ]]></content> <tabTrigger>forloop</tabTrigger> <scope>source.js</scope> </snippet></pre><p> Once saved (via <strong>Tools > Developer > New Snippet</strong> ), typing <code>forloop</code> followed by <code>Tab</code> will expand into a full loop with placeholders you can tab through.</p> <p> Make sure your snippets are scoped correctly so they only appear where they should — that way you don't end up inserting HTML tags inside a Python file by accident.</p> <hr> <p> That's the core of making auto-complete work for you in Sublime Text. It doesn't do AI-style completions out of the box, but with a little setup and some custom snippets, it becomes a solid tool for faster coding.</p>
