[hakyll] Syntax highlighting creating anchor tags?

[m***@robertwpearce.com]

I opened a GitHub issue (https://github.com/jaspervdj/hakyll/issues/662)
but am unsure how actively maintained it is over there so thought I'd try
here.

Hi! Thanks for making this project. I'm new to Hakyll and have converted
my blog/website over, but there's one thing preventing me from publishing:
syntax highlighting for a given language seems to use anchor tags within
the code block, itself. Simple steps to reproduce:

1. `$ hakyll-init the-site`
1. `$ cd the-site`
1. `$ stack init`
1. `$ stack build`
1. `$ stack exec site build`
1. `$ vim posts/2015-08-12-spqr.markdown`
1. add the following to the post content:
```
```
const abc = 123
```
```
1. `$ stack exec site watch`
1. `$ open http://localhost:8000/posts/2015-12-07-tu-quoque.html`
1. view the HTML for the code block:
```html
<div class="sourceCode" id="cb1">
<pre class="sourceCode js">
<code class="sourceCode javascript">
<a class="sourceLine" id="cb1-1" data-line-number="1">
<span class="kw">const</span> abc <span class="op">=</span> <span
class="dv">123</span>
</a>
</code>
</pre>
</div>
```

As you can see, an `<a>` tag is created, which doesn't seem like that
should be there? Is that just how pandoc works or something? Wonder what
I'm missing...

Any help would be much appreciated!

Hi,

Yes, it seems like this is the default for Pandoc now:

$ pandoc --version
pandoc 2.1.2

$ echo -ne '```haskell\nputStrLn "Hello, world"\n```\n' | pandoc
<div class="sourceCode" id="cb1">
<pre class="sourceCode haskell">
<code class="sourceCode haskell">
<a class="sourceLine" id="cb1-1" data-line-number="1">
putStrLn <span class="st">&quot;Hello, world&quot;</span>
</a>
</code>
</pre>
</div>

I suspect the goal of this is to be able to link to specific lines in a
codeblock. For example, I can private message someone a link to

http://example.com/blog/foo#cb1-1

Is this messing up the default CSS? In that case, I can update that.

Hope this helps
Jasper

Thanks for getting back to me so quickly. It does *not* mess up the default CSS — only on my own things, which is my problem.

Thank you, and I’ll close the issue ASAP on GitHub.
