VS Code保存后多行内容合并为一行问题求助

Hey there! Let's troubleshoot why your multi-line text is getting squashed into a single line with automatic numbering when you hit Ctrl+S in VS Code. This issue almost always stems from misconfigured auto-formatting settings or an overzealous extension. Here's how to fix it step by step:

1. Disable Suspicious Formatting Extensions #

First, let's rule out third-party extensions that might be overriding your formatting:

• Open the Extensions panel with Ctrl+Shift+X.
• Search for extensions related to formatting (like Prettier, ESLint, or any "list formatter" tools).
• Temporarily disable each one, save your file again, and check if the problem goes away.
• If you find the culprit, adjust its settings: either turn off "Format On Save" for that extension, or exclude your file type (e.g., plain text) from its formatting rules.

2. Tweak VS Code's Built-In Formatting Settings #

If extensions aren't the issue, check the editor's core settings:

• Open the Settings UI with Ctrl+,.
• Search for Editor: Format On Save and uncheck the box. Save your file to test if the multi-line format stays intact.
• If you still want formatting for other file types but not your current one, create a file-specific rule:
  • Open your settings.json file by pressing Ctrl+Shift+P and selecting "Open Settings (JSON)".
  • Add this snippet (replace plaintext with your file type if needed, like markdown):

    "[plaintext]": {
        "editor.formatOnSave": false
    }
    

3. Verify Keyboard Shortcuts #

Double-check that Ctrl+S isn't bound to any unexpected commands:

• Open the Keyboard Shortcuts panel with Ctrl+K Ctrl+S.
• Search for "save" and ensure Ctrl+S only maps to the files.save command. Remove any conflicting bindings if you find them.

4. Check for Auto-List Formatting #

Since your saved text is getting numbered (1., 2., 3.), there might be an extension that automatically converts multi-line text into ordered lists. Look for extensions with names like "List Tools" or "Auto List Format" and disable them to test.

Once you've gone through these steps, your multi-line text should stay as-is when you save it in VS Code!
