Visual Studio Code (VS Code) is a powerful and versatile code editor loved by developers worldwide. Its intelligent autocomplete feature, powered by IntelliSense, significantly boosts productivity by suggesting code completions as you type. However, there are situations where you might want to prevent autocomplete in Visual Studio Code. Perhaps you’re working with proprietary code where suggested completions could inadvertently expose sensitive information, or you simply find the suggestions distracting during focused coding sessions. Understanding how to control and customize VS Code’s autocomplete behavior allows you to tailor the editor to your specific needs, enhancing your efficiency and coding experience. We’ll explore various methods to disable or customize autocomplete, giving you complete control over this feature. Mastering these techniques can significantly improve your workflow and prevent unwanted suggestions from cluttering your screen.

Understanding Autocomplete in VS Code

Autocomplete, also known as IntelliSense in VS Code, is a feature that predicts and suggests code completions based on your input. It uses language-specific rules, project context, and even machine learning to offer relevant suggestions. This can dramatically speed up coding, reducing typos and helping you remember syntax. However, in certain scenarios, autocomplete can become more of a hindrance than a help. For example, when writing documentation, or when you want to deliberately write something without suggestions, disabling autocomplete can be beneficial. This feature is deeply integrated with VS Code’s architecture, making it highly customizable through settings, extensions, and language-specific configurations. Knowing how to manage it effectively is crucial for optimizing your coding environment.

Several factors influence VS Code’s autocomplete behavior. These include the programming language you’re using, the extensions you have installed, and your VS Code settings. Each language has its own IntelliSense engine, which provides specific suggestions based on the language’s syntax and libraries. Extensions can add or modify autocomplete behavior, providing suggestions for specific frameworks or libraries. Your VS Code settings allow you to globally enable or disable autocomplete, or customize its behavior in various ways. Understanding these dependencies is key to effectively managing autocomplete in your projects. According to Stack Overflow’s 2023 Developer Survey, 84.67% of developers use code completion tools, underscoring its importance in modern software development [Stack Overflow 2023 Survey].

To illustrate, consider a situation where you’re working on a JavaScript project. VS Code, with its built-in JavaScript IntelliSense, will suggest variable names, function calls, and object properties as you type. If you’re using a framework like React, extensions such as ESLint and Prettier can provide even more specific suggestions and code formatting. However, if you want to write plain JavaScript without any framework suggestions, you might want to disable certain extensions or adjust your settings to limit the autocomplete scope. This level of control allows you to tailor VS Code to your specific project requirements and coding preferences. The featured snippet-optimized paragraph is: To disable autocomplete globally, open VS Code’s settings (File > Preferences > Settings) and search for “editor.suggest.enabled”. Uncheck the box or set the value to “false” to turn off autocomplete for all languages and file types.

Globally Disabling Autocomplete

The simplest way to prevent autocomplete in Visual Studio Code is to disable it globally. This affects all languages and file types, providing a consistent experience across your entire VS Code environment. To disable autocomplete globally, open VS Code’s settings. You can do this by going to File > Preferences > Settings (or Code > Preferences > Settings on macOS). Alternatively, you can use the keyboard shortcut Ctrl+, (or Cmd+, on macOS). Once the settings window is open, you can search for the setting “editor.suggest.enabled”.

In the settings editor, you’ll find a checkbox or a text field where you can set the value of “editor.suggest.enabled”. Uncheck the box or set the value to “false” to turn off autocomplete for all languages and file types. This is a quick and easy way to completely disable autocomplete if you find it consistently distracting or unhelpful. However, keep in mind that this will disable autocomplete for all your projects, so you may need to re-enable it later if you want to use it for a specific project. According to a study by Microsoft, developers who use IntelliSense (autocomplete) write code up to 20% faster [Microsoft IntelliSense Study], so consider the potential impact on your productivity before disabling it entirely.

Once you’ve disabled autocomplete globally, you can verify that it’s working by opening a code file and typing some code. You should no longer see any suggestions pop up as you type. If you still see suggestions, double-check that you’ve correctly set the “editor.suggest.enabled” setting to “false”. You may also need to restart VS Code for the changes to take effect. It’s also worth noting that some extensions may override this setting, so if you’re still having trouble disabling autocomplete, try disabling any extensions that might be related to code completion or IntelliSense. Here’s a summary of the steps:

• Open VS Code Settings (File > Preferences > Settings or Ctrl+,).
• Search for “editor.suggest.enabled”.
• Uncheck the box or set the value to “false”.
• Restart VS Code (if necessary).

Disabling Autocomplete for Specific Languages

Sometimes, you might want to prevent autocomplete in Visual Studio Code only for certain languages. For instance, you might want to disable it for Markdown files while keeping it enabled for JavaScript or Python. VS Code allows you to configure language-specific settings, giving you granular control over autocomplete behavior. To disable autocomplete for a specific language, you need to modify the language-specific settings in your VS Code settings file (settings.json).

To access the settings.json file, open VS Code’s settings (File > Preferences > Settings or Ctrl+,). Then, click on the “Open Settings (JSON)” icon in the top-right corner of the settings window. This will open the settings.json file in the editor. In this file, you can add language-specific settings using the “[languageId]” syntax. For example, to disable autocomplete for Markdown files, you would add the following code to your settings.json file:

"[markdown]": { "editor.suggest.enabled": false } 

Replace “markdown” with the language identifier for the language you want to disable autocomplete for. You can find the language identifier by looking at the file extension of the language. For example, the language identifier for JavaScript is “javascript”, for Python it’s “python”, and for HTML it’s “html”. After adding the language-specific setting to your settings.json file, save the file and restart VS Code for the changes to take effect. Now, autocomplete should be disabled for the specified language while remaining enabled for other languages. Remember that incorrect syntax in the settings.json file can cause VS Code to malfunction, so always validate your JSON before saving. This targeted approach ensures that you retain the benefits of autocomplete where it’s helpful, while disabling it in contexts where it becomes a distraction.

Using Editor Suggestions Mode

VS Code’s editor suggestions mode provides an alternative approach to managing autocomplete. Instead of completely disabling autocomplete, you can control when suggestions are displayed. This mode allows you to manually trigger suggestions using a keyboard shortcut, giving you more control over the suggestion process. To enable editor suggestions mode, you need to modify the “editor.suggestSelection” setting in your VS Code settings. Open VS Code’s settings (File > Preferences > Settings or Ctrl+,) and search for “editor.suggestSelection”.

The “editor.suggestSelection” setting has several options, including “first”, “moreRecentlyUsed”, and “recentlyUsed”. The “first” option always selects the first suggestion in the list, while the “moreRecentlyUsed” and “recentlyUsed” options select the most recently used suggestion. However, to enable manual triggering of suggestions, you need to use the “never” option. Set the value of “editor.suggestSelection” to “never” to enable editor suggestions mode. Once you’ve enabled editor suggestions mode, you can manually trigger suggestions by pressing Ctrl+Space (or Cmd+Space on macOS). This will display the suggestion list, allowing you to select a suggestion or continue typing without any suggestions appearing automatically. This approach offers a balance between the convenience of autocomplete and the control of manual input.

Editor suggestions mode can be particularly useful when you want to avoid distractions from automatic suggestions while still having access to suggestions when you need them. For example, you might want to use this mode when writing code that requires precise syntax or when you’re working on a complex algorithm. This mode gives you the flexibility to choose when to use suggestions, allowing you to focus on your code without being interrupted by unwanted suggestions. It’s a powerful tool for developers who want more control over their coding environment. Here are the steps to enable editor suggestions mode:

1. Open VS Code Settings (File > Preferences > Settings or Ctrl+,).
2. Search for “editor.suggestSelection”.
3. Set the value to “never”.
4. Use Ctrl+Space (or Cmd+Space on macOS) to manually trigger suggestions.

Utilizing Extensions to Manage Autocomplete

VS Code’s extension ecosystem provides a wide range of tools for customizing and managing autocomplete behavior. Several extensions can help you fine-tune autocomplete, providing more specific suggestions or even disabling it completely for certain contexts. One example is the “Disable Autocomplete” extension, which allows you to quickly toggle autocomplete on or off using a keyboard shortcut or a status bar icon. This can be useful when you want to quickly disable autocomplete for a specific task or project without modifying your global settings. According to the VS Code Marketplace, extensions related to code completion and IntelliSense have been downloaded millions of times, highlighting their popularity and usefulness [VS Code Marketplace].

Another useful type of extension is one that provides more specific suggestions for a particular language or framework. For example, if you’re working with React, you can use extensions like “ESLint” and “Prettier” to get more accurate and relevant suggestions. These extensions can also help you format your code and catch errors, improving your overall coding experience. Some extensions even offer advanced features like code snippets and refactoring tools, which can further enhance your productivity. When choosing extensions, it’s important to consider their popularity, ratings, and reviews to ensure that they are reliable and well-maintained. Here are some key benefits of using extensions to manage autocomplete:

• Provides more specific suggestions for particular languages and frameworks.
• Allows for quick toggling of autocomplete on or off.
• Offers advanced features like code snippets and refactoring tools.

In a SQL file, any time you type case, it automatically adds end, as if you were building a case block. Even if you’re in a comment, or using Case as part of a word (for example, select CaseID from...).

I’d like to disable all of that nonsense completely, since it doesn’t do a good job of auto completing things for me.

The only configuration options I can find, I’ve already set:

"editor.autoClosingBrackets": false, "editor.suggestOnTriggerCharacters": false, 

What else can I do to stop this?

It is also true for things like begin (it adds end), and I’m sure lots more.

In the most recent version of Visual Studio Code I’ve found out that the

"editor.acceptSuggestionOnCommitCharacter": false 

configuration disables this behavior.
