Programming Languages
Hundreds of programming languages supported
In Visual Studio Code, we have support for almost every major programming language. Several ship in the box, for example, JavaScript, TypeScript, CSS, and HTML but more rich language extensions can be found in the VS Code Marketplace.
Here are eight of the most popular language extensions:
Go to the Marketplace or use the integrated Extensions view and search for your desired programming language to find snippets, code completion/IntelliSense providers, linters, debuggers, and more.
Note: If you want to change the display language of VS Code (for example, to Chinese), see the Display Language topic.
Language specific documentation
Learn about programming languages supported by VS Code. These include: C++ - C# - CSS - Dart - Dockerfile - F# - Go - HTML - Java - JavaScript - JSON - Julia - Less - Markdown - PHP - PowerShell - Python - R - Ruby - Rust - SCSS - Swift - T-SQL - TypeScript.
Click on any linked item to get an overview of how to use VS Code in the context of that language. Most language extensions also contain a summary of their core features in their README.
Language features in VS Code
The richness of support varies across the different languages and their extensions:
- Syntax highlighting and bracket matching
- Smart completions (IntelliSense, Artificial Intelligence with GitHub Copilot)
- Linting and corrections
- Code navigation (Go to Definition, Find All References)
- Debugging
- Refactoring
Enhance completions with AI
In VS Code, you can enhance your coding with artificial intelligence (AI), such as suggestions for lines of code or entire functions, fast documentation creation, and help creating code-related artifacts like tests.
GitHub Copilot is an AI-powered code completion tool that helps you write code faster and smarter. You can use the GitHub Copilot extension in VS Code to generate code, or to learn from the code it generates.
You can learn more about how to get started with Copilot in the Copilot documentation.
Change the language for the selected file
In VS Code, we default the language support for a file based on its filename extension. However, at times you may want to change language modes, to do this click on the language indicator - which is located on the right hand of the Status Bar. This will bring up the Select Language Mode dropdown where you can select another language for the current file.
Tip: You can get the same dropdown by running the Change Language Mode command (⌘K M (Windows, Linux Ctrl+K M)).
Language identifier
VS Code associates a language mode with a specific language identifier so that various VS Code features can be enabled based on the current language mode.
A language identifier is often (but not always) the lowercased programming language name. Note that casing matters for exact identifier matching ('Markdown' != 'markdown'). Unknown language files have the language identifier plaintext.
You can see the list of currently installed languages and their identifiers in the Change Language Mode (⌘K M (Windows, Linux Ctrl+K M)) dropdown.
You can find a list of known identifiers in the language identifier reference.
Add a file extension to a language
You can add new file extensions to an existing language with the files.associations setting.
For example, the setting below adds the .myphp file extension to the php language identifier:
"files.associations": { "*.php4": "php", "*.php5": "php" }You can also configure full file paths to languages if needed. The following example associates all files in a folder somefolder to PHP:
// The default language mode that is assigned to new files. "files.defaultLanguage": "html"
