IntelliJ Ultimate 2018.1文档无法自动换行问题求助

Hey there! Let’s work through that frustrating document auto-wrap problem you’re facing. Here are some targeted steps to try, based on your setup and test results:

1. Double-Check Core Soft-Wrap Settings #

First, make sure your global editor settings are configured correctly:

• Go to File → Settings → Editor → General (or IntelliJ IDEA → Preferences on Mac)
• Under the Soft-wrap section:
  • Tick Use soft wraps in editor and Use soft wraps in console
  • Verify your target file types (like .md, .txt, .kt) are listed in Soft-wrap these files
  • If you want code lines to wrap too, check Allow soft wraps in code and adjust the Do not wrap lines longer than threshold to a reasonable value (e.g., 120)

2. Fix Quick Documentation Popup Wrapping #

Since switching to popup mode didn’t help, check the dedicated setting for documentation windows:

• Navigate to File → Settings → Editor → General → Quick Documentation
• Look for the Soft-wrap long lines option and enable it. This should force wrapping in the documentation popups you’re using.

3. Resolve Plugin Conflicts (Kotlin/Cursive) #

Your test showed partial success when disabling Cursive, which points to potential plugin conflicts:

• Update plugins: Go to File → Settings → Plugins, check for updates for the Kotlin plugin and Cursive (if you plan to use it later). Old plugin versions often clash with older IDE builds like 2018.1.
• Safe Mode Test: Restart IntelliJ while holding Shift (Windows/Linux) or Option (Mac) to launch in Safe Mode (all third-party plugins disabled). If auto-wrap works here, enable plugins one by one to find the culprit.

4. Quick Workarounds to Try #

If the above steps don’t fix it immediately:

• Use the keyboard shortcut Ctrl+Shift+A (Windows/Linux) or Cmd+Shift+A (Mac), search for Toggle Soft Wrap, and run it—this can manually trigger wrapping for the current window.
• Reset UI scaling: Go to File → Settings → Appearance & Behavior → Appearance, reset the UI Options font scaling to default. Sometimes odd scaling breaks auto-wrap logic.

Since you mentioned IDEA-169414 doesn’t apply here, these steps should address the specific issues you’re seeing with partial Kotlin documentation wrapping and persistent popup problems.
