1. Common Commands

1.1 Create New Post

hexo new [layout] <title>

e.g.

hexo new "post title with whitespace"

1.2 Create Post in Subdirectory

By default, new files are created in the _posts directory. When you have many posts, it’s inconvenient to find them. You can create a directory under _posts, such as dir, then use the following command to create a post in the _posts/dir directory:

hexo new -p dir/test -s "test" "测试"
# test is the post filename
# 测试 is the post title

# -p, --path	Customize the path for new post
# -s, --slug	Post slug, used as filename and URL after publication

2. Common Syntax

2.1 Internal Post Linking

{% post_link Post Title %}

e.g.

{% post_link nginx-common-commands %}

Note: {% post_link %} is Hexo-specific tag syntax. In Astro/MDX, you need to use Markdown link syntax, for example: [nginx-common-commands](/en/blog/nginx-common-commands/)

2.2 Pin Single Post

sticky: 1

Note: sticky is a Hexo frontmatter field. In Astro, you can implement similar functionality through custom fields.

2.3 Collapsible Content

In Hexo, use the <details> tag for collapsing:

<details><summary>Summary content</summary>

(Leave a blank line above) This is the actual content to be expanded.
</details>

Or use the {% spoiler %} tag:

{% spoiler Answer %}
Reference answer
{% endspoiler %}

{% spoiler "Several spaces in the title" %}
content
{% endspoiler %}

Note: {% spoiler %} is Hexo-specific tag syntax. In Astro/MDX, you can use the HTML <details> tag to achieve the same collapsing effect.
