I am using the standard jekyll installation to maintain a blog, everything is going fine. Except I would really like to tag my posts.
I can tag a post using the YAML front matter, but how do I generate pages for each tag that can will list all posts for a tag?
This gist will generate a page per category for you: https://gist.github.com/524748
It uses a Jekyll Generator plugin, plus a Page subclass.
I had the same question, and stumbled upon this: http://gist.github.com/143571.
It's a rake task which generates a tag list. I modified it slightly, and my version is at: http://github.com/mattfoster/mattfoster.github.com/blob/master/Rakefile.
Whilst this doesn't give you a page per tag, you can use anchors, which is half way there!
I do these with CSS. First lists an element and use the tag name as its id.
<span id="{{ site.posts | map: 'tags' | uniq | join: '"></span><span id="' }}"></span>
And then lists all the post and use its tags as a value for the "tags" custom attribute.
{% for post in site.posts %}
<article class="post" tags="{% for tag in post.tags %}{{tag}}{% if forloop.last == false %}{{" "}}{% endif %}{% endfor %}">
<h3><a href="{{post.url}}">{{post.title}}</a></h3>
</article>
{% endfor %}
And then in CSS, hide all the posts by default, and only show posts with tags matches the url id/ hash
.post {
display: none;
}
{% for tag in site.tags %}#{{tag[0]}}:target ~ [tags~={{tag[0]}}]{% if forloop.last == false %}, {% endif %}{% endfor %} {
display: block;
}
/*
The compiled version will look like this
#tagname:target ~ [tags~="tagname"], #tagname2:target ~ [tags~="tagname2"] {
display: block;
}
*/
I made an article about this here.
