帖子总数？

Question

我正在试图弄清楚如何显示一个类别(或所有)中的帖子总数.我想象下面的东西,但不能完全理解.我是否遗漏了文档中的内容？

{% 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

# all posts

{{ site.posts | size }}

# posts in one category

{{ site.categories.CAT | size }}

Answer 2

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