Jan 2nd, 2022 under Programming Jekyll
With moving my site off of Wordpress, I landed on Jekyll, but wanted to add an RSS feed option. Here is a simple way, without plugins.
One of its example Generator plugins for Jekyll is their jekyll-feed plugin, used as a reference for those creating similar style file generation. Since I am Gemfile less currently, I really didnt want to add another configuration item, and it dawned on me…just build the RSS feed using templates and liquid!
Below is an example of just that, a template for atom 2.0 formatted post list.

permalink: /feed.xml
---<feed xmlns="http://www.w3.org/2005/Atom">
<title>{{ site.title }}</title>
<subtitle>{{ site.tagline }}</subtitle>
<link href="{{ site.url}}/feed/" rel="self" />
<link href="{{ site.url}}" />
<id>{{ site.url}}</id>
<updated>{{ site.time | date: '%FT%TZ' }}</updated>
{% for post in site.posts %}
<entry>
<title>{{ post.title | xml_escape}}</title>
<updated>{{ post.date | date: '%FT%TZ' }}</updated>
<id>{{ site.url}}{{ post.url }}</id>
<link>{{ site.url}}{{ post.url }}</link>
<summary>{{ post.excerpt | strip_html | xml_escape }}</summary>
</entry>
{% endfor %}
</feed>
