Permalinks

You can specify the permalinks for your site in _config.yml or in the front-matter for each post.

Besides the following variables, you can use any attributes in the permalink except :path and :permalink.

Variable	Description
`:year`	Published year of posts (4-digit)
`:month`	Published month of posts (2-digit)
`:i_month`	Published month of posts (Without leading zeros)
`:day`	Published day of posts (2-digit)
`:i_day`	Published day of posts (Without leading zeros)
`:hour`	Published hour of posts (2-digit)
`:minute`	Published minute of posts (2-digit)
`:second`	Published second of posts (2-digit)
`:title`	Filename (relative to “source/_posts/“ folder)
`:name`	Filename
`:post_title`	Post title
`:id`	Post ID (not persistent across cache reset)
`:category`	Categories. If the post is uncategorized, it will use the `default_category` value.
`:hash`	SHA1 hash of filename (same as `:title`) and date (12-hexadecimal)

You can define the default value of each variable in the permalink through the permalink_defaults setting:

permalink_defaults:
  lang: en

source/_posts/hello-world.md

title: Hello World
date: 2013-07-14 17:01:34
categories:
  - foo
  - bar

source/_posts/lorem/hello-world.md

title: Hello World
date: 2013-07-14 17:01:34
categories:
  - foo
  - bar

Setting	Result
`:year/:month/:day/:title/`	2013/07/14/lorem/hello-world/
`:year/:month/:day/:name/`	2013/07/14/hello-world/

To create a multi-language site, you can modify the new_post_name and permalink settings like this:

new_post_name: :lang/:title.md
permalink: :lang/:title/

When you create a new post, the post will be saved to:

$ hexo new "Hello World" --lang tw
# => source/_posts/tw/Hello-World.md

and the URL will be:

http://localhost:4000/tw/hello-world/
