Total number of posts?

Question

I'm trying to figure out how to display the total number of posts in a category (or all together). I envision something like below, but can't quite figure it out. Did I miss something from the docs?

{% for post in site.categories.CAT %}
    ...do some counting
{% endfor %}

posts: {% number_of_posts %}

{% for post in site.categories.CAT %}
    {{ post.title }}
{% endfor %}

Answer 1

{% for post in site.categories.CAT %}
   {% capture post_count %} {{ post_count | plus: 1 }} {% endcapture %}
{% endfor %}
{{ post_count }}
