Static Jekyll Comments

Static Jekyll Comments

Those of you paying very close attention will have noticed that posts now have a comment section at the bottom. It’s currently reading the comments reading in from specially named YAML files in the _data directory of the site, which I have to put in manually.

You can find my comment HTML and YAML on GitHub, hopefully it’s pretty straight self-explanatory.

To do it, I had to get a filename-friendly page identifier from the, which I did by replacing slashes with dashes and capturing it in a comment id.

{% capture commentid %}comments{{ page.id | replace: '/','-'}}{% endcapture %}

From here, I read the data from site.data[commentid] and display it on the page. I wanted to allow some formatting in comments, so I pass the content through the | markdownify filter. The comment contents in the YAML have to be multi line as well, ending up with a YAML file with a bunch of entries like so:

- author: Steve
  date: 2014-04-02 10:00 +1000
  contents: |
    I've added comment support to the site now! See [my post](/2014/04/static-jekyll-comments) to see how I went about it.

    You'll note that it has *markdown* support too! I'll moderating it though, so don't try any dirty hacks...

The plan now is to make use of the GitHub API to allow comment submission by creating issues. I think this means that the commenter requires GitHub account, but that’s ok. I don’t think I’ll get enough comments to need more automation than that - I will want to moderate them to ensure there’s nothing malicious in the comment anyway, so I don’t mind having to copy-paste the markdown from the GitHub issue into a YAML file.

For now, you’ll have to create the GitHub issue yourself!
