# Site Maintenance for Hugo v0.60

### Background

I lacked motivation to keep this tweaked theme up with Hugo‘s development after last summer. When I came back yesterday, I saw that some pages using Font Awesome icons were broken. Apart from that, the ToC list level problem resurfaced.

### Fixed ToC

The solution that I had adopted no longer worked. Luckily, some users provided a shorter code in the later discussions. The one from user501254 caught me. I first tried to copy his code into the partial layout for ToC. However, nothing changed.

{{ $emtLiPtrn := "(?s)<ul>\\s<li>\\s<ul>(.*)</li>\\s</ul>" }} {{$rplcEmtLi := "<ul>$1" }} {{ .TableOfContents | replaceRE$emtLiPtrn $rplcEmtLi | safeHTML }} In an attempt to identify the cause of this error, I looked for the official docs for replaceRE, whose syntax seemed to be unchanged. I then played with the PATTERN and REPLACEMENT with some simple syntax—that worked. This showed that the problem was about$emtLiPtrn. Thanks to https://regex101.com/ and the generated HTML source code, I found that appending an asterisk * after each \\s in \$emtLiPtrn fixed the issue.

<aside class="toc-article">
<nav id="TableOfContents">
<ul>
<li>
<ul>
<li><a href="#for-each-ref">for-each-ref</a></li>
<li><a href="#ls-files-ls-tree">ls-files, ls-tree</a></li>
<li><a href="#merge-base">merge-base</a></li>
<li><a href="#merge---squash-rebase--i">merge –squash, rebase -i</a></li>
<li><a href="#reflog">reflog</a></li>
<li><a href="#rev-parse">rev-parse</a></li>
<li><a href="#diff">diff</a></li>
</ul>
</li>
</ul>
</nav>
</aside>

This fix is available online at commit a3d7343a on GitLab.

Remarks: In the linked regex testing website, the “golang” favour has to be chosen, and use \s instead of \\s.

### Fixed missing Font Awesome icons

In the page for Math.SE comment templates, the text areas disappeared. Inspecting the elements, the message <!-- raw HTML omitted --> popped up. Thanks to this Japanese article, I quickly solved this problem at commit 74c81df0 on GitLab.
