如何在BBedit中使用代码补全？属性补全正常但值无补全

Hey there, let’s work through this BBEdit quirk where your CSS property values (like uppercase or vertical-align values) aren’t showing up in completions—even though the properties themselves work fine. I’ve dealt with similar issues before, so here are some practical steps to resolve it:

• Double-check CSS-specific completion settings
  You’ve already enabled global text completions, but let’s confirm the CSS language settings are locked in:
  Open Preferences > Languages > CSS, make sure "Enable completions" is checked, and under "Completion Sources", verify that "CSS Property Values" is ticked off. Sometimes this specific toggle gets disabled accidentally, which blocks value suggestions.

• Clear BBEdit’s completion cache
  Corrupted cache files are a common culprit for wonky completions. Here’s how to fix it:

  1. Quit BBEdit completely.
  2. Navigate to ~/Library/Application Support/BBEdit/Completion Caches (you can access the Library folder by holding Option while clicking the Go menu in Finder).
  3. Delete any CSS-related cache files (look for names like CSS.cache).
  4. Restart BBEdit—it’ll rebuild the cache automatically. Try typing text-transform: u or vertical-align: t afterward to see if completions pop up.

• Verify you’re using standard CSS property names
  Quick sanity check: The standard CSS property is text-transform, not text-transformation. If you’re typing the non-standard version, BBEdit might not recognize the corresponding values even if it completes the property itself. Stick to the standard property names to ensure value completions work as expected.

• Reinstall the CSS language module (or update BBEdit)
  If the above steps don’t work, the CSS language support files might be corrupted. Head to Preferences > Languages, select CSS, and look for an option to "Reinstall Language Module" (location varies slightly by BBEdit version). Alternatively, download the latest version of BBEdit and do a clean overwrite install—updating often fixes these small, annoying bugs.

• Add custom completions (temporary workaround)
  If all else fails, you can manually add the values you need:
  Go to BBEdit > Text Factories > Completions, create a new CSS completion group, and add entries like uppercase, lowercase, top, middle, etc. This ensures BBEdit will suggest these values whenever you’re working in CSS files.
