Click the language mode on the status bar and select the desired language; 2. Use Ctrl Shift P to open the Command Palette, type "Change Language Mode", and choose the language; 3. Edit settings.json to map file extensions to specific languages using "files.associations"; 4. For project-specific settings, add the association in .vscode/settings.json within the workspace folder—this ensures correct syntax highlighting and language features are applied automatically.
Changing the language mode in VS Code is useful when you want to apply specific syntax highlighting or language features to a file. Here's how you can do it:
1. Change Language Mode via the Status Bar
The quickest way is through the bottom-right corner of the VS Code window:
- Open the file you want to modify.
- Look at the bottom-right of the status bar — it usually shows the current language mode (e.g., "Plain Text", "JavaScript", "Python").
- Click on it.
- A dropdown will appear showing available language modes.
- Start typing to filter the list (e.g., type "JSON", "HTML", "Python").
- Select the correct language, and the syntax highlighting and IntelliSense will update accordingly.
2. Use the Command Palette
If you prefer using commands:
- Press
Ctrl Shift P(orCmd Shift Pon Mac) to open the Command Palette. - Type "Change Language Mode" and select it.
- Then choose the desired language from the list.
3. Set Language Mode for Specific File Extensions
You can configure VS Code to automatically assign a language mode based on file extension:
- Go to File > Preferences > Settings (or press
Ctrl ,). - Search for "files.associations".
- Click "Edit in settings.json".
- Add a mapping like:
"files.associations": { "*.log": "plaintext", "*.config": "xml", "*.myext": "python" }This tells VS Code to treat files with those extensions using the specified language mode.
4. Apply Language Mode to All Files in a Workspace
If you want to set a default language mode for certain files in just one project:
- Open the workspace folder.
- Create a
.vscode/settings.jsonfile inside the folder. - Add the
files.associationssetting there — it will only apply to that project.
Language mode affects syntax highlighting, bracket matching, and language-specific features like linting or auto-completion. So choosing the right one helps keep your code readable and well-supported.
Basically, just click the bottom-right corner and pick the right language — everything else updates automatically.
