Limit number of tags in content

Question

there is that old blog post to get a list of categories and tags from the content.

I only found tag_cloud as the only plugin dealing with tags no further mention in the documentation

Is there any way to limit the usable tags e.g. through the configs ?

Answer 1

One option is you can define a ALLOWED_TAGS variable in pelicanconf.py to contain the tags that you want to allow, then in places where tags are placed you can add a JINJA if block to allow only these tags

#pelicanconf.py

...

ALLOWED TAGS = ("tag1", "tag2", "tag3", tag4") 

Example of generating tags for an article below

<div class="article-tags">
    {% for tag in article.tags %}
    {% if tag in ALLOWED_TAGS %}
    <a href="/tags/{{tag}}"><{{tag}}</span></a>
    {% endif %}
    {% endfor %}
</div>
