Rmarkdown Front Matter设toc:true后HTML输出出现多余"true"的解决方法

It sounds like your Hugo theme’s template is accidentally outputting the raw toc: true value instead of using it to conditionally render the table of contents. Here’s how to fix this:

• Inspect your theme’s layout files: Head to your theme’s directory (you can find its path with hugo list themes in your terminal) and look for files that reference the toc parameter. Common spots are layouts/_default/single.html or a partial like layouts/partials/toc.html. If you see code like {{ .Params.toc }}, that’s the issue—it’s directly printing the boolean value. Replace that with a conditional check to only render the TOC when toc is true:

  {{ if .Params.toc }}
    {{ .TableOfContents }} <!-- or whatever your theme uses to generate the TOC -->
  {{ end }}
  

• Check other front matter flags: If you also see "false" from your draft: false line, make sure your theme isn’t printing the draft parameter anywhere. Hugo handles draft posts natively (it won’t render them by default unless you use hugo server -D), so any explicit output of draft in templates is unnecessary and should be removed.
• Review your custom script: Since you have script: 'scales' in your front matter, double-check that this script isn’t reading and outputting the toc value by mistake. Look through the script code to ensure it’s not accessing front matter parameters and printing them unconditionally.

If you’re having trouble locating the problematic template code, use your code editor’s search function to look for .Params.toc across your theme’s files—that should point you right to it.
