Variables

Jekyll traverses your site looking for files to process. Any files with front matter are subject to processing. For each of these files, Jekyll makes a variety of data available via Liquid. The following is a reference of the available data.

Global Variables

Variable	Description
site	Site wide information + configuration settings from _config.yml. See below for details.
page	Page specific information + the front matter. Custom variables set via the front matter will be available here. See below for details.
layout	Layout specific information + the front matter. Custom variables set via front matter in layouts will be available here.
content	In layout files, the rendered content of the Post or Page being wrapped. Not defined in Post or Page files.
paginator	When the paginate configuration option is set, this variable becomes available for use. See Pagination for details.

Site Variables

Variable	Description
site.time	The current time (when you run the jekyll command).
site.pages	A list of all Pages.
site.posts	A reverse chronological list of all Posts.
site.related_posts	If the page being processed is a Post, this contains a list of up to ten related Posts. By default, these are the ten most recent posts. For high quality but slow to compute results, run the jekyll command with the --lsi (latent semantic indexing) option. Also note GitHub Pages does not support the lsi option when generating sites.
site.static_files	A list of all static files (i.e. files not processed by Jekyll's converters or the Liquid renderer). Each file has five properties: path, modified_time, name, basename and extname.
site.html_pages	A subset of site.pages listing those which end in .html.
site.html_files	A subset of site.static_files listing those which end in .html.
site.collections	A list of all the collections (including posts).
site.data	A list containing the data loaded from the YAML files located in the _data directory.
site.documents	A list of all the documents in every collection.
site.categories.CATEGORY	The list of all Posts in category CATEGORY.
site.tags.TAG	The list of all Posts with tag TAG.
site.url	Contains the url of your site as it is configured in the _config.yml. For example, if you have url: http://mysite.com in your configuration file, then it will be accessible in Liquid as site.url. For the development environment there is an exception, if you are running jekyll serve in a development environment site.url will be set to the value of host, port, and SSL-related options. This defaults to url: http://localhost:4000.
site.[CONFIGURATION_DATA]	All the variables set via the command line and your _config.yml are available through the site variable. For example, if you have foo: bar in your configuration file, then it will be accessible in Liquid as site.foo. Jekyll does not parse changes to _config.yml in watch mode, you must restart Jekyll to see changes to variables.

Page Variables

Variable	Description
page.content	The content of the Page, rendered or un-rendered depending upon what Liquid is being processed and what page is.
page.title	The title of the Page.
page.excerpt	The un-rendered excerpt of a document.
page.url	The URL of the Post without the domain, but with a leading slash, e.g. /2008/12/14/my-post.html
page.date	The Date assigned to the Post. This can be overridden in a Post’s front matter by specifying a new date/time in the format YYYY-MM-DD HH:MM:SS (assuming UTC), or YYYY-MM-DD HH:MM:SS +/-TTTT (to specify a time zone using an offset from UTC. e.g. 2008-12-14 10:30:00 +0900).
page.id	An identifier unique to a document in a Collection or a Post (useful in RSS feeds). e.g. /2008/12/14/my-post/my-collection/my-document
page.categories	The list of categories to which this post belongs. Categories are derived from the directory structure above the _posts directory. For example, a post at /work/code/_posts/2008-12-24-closures.md would have this field set to ['work', 'code']. These can also be specified in the front matter.
page.collection	The label of the collection to which this document belongs. e.g. posts for a post, or puppies for a document at path _puppies/rover.md. If not part of a collection, an empty string is returned.
page.tags	The list of tags to which this post belongs. These can be specified in the front matter.
page.dir	The path between the source directory and the file of the post or page, e.g. /pages/. This can be overridden by permalink in the front matter.
page.name	The filename of the post or page, e.g. about.md
page.path	The path to the raw post or page. Example usage: Linking back to the page or post’s source on GitHub. This can be overridden in the front matter.
page.next	The next post relative to the position of the current post in site.posts. Returns nil for the last entry.
page.previous	The previous post relative to the position of the current post in site.posts. Returns nil for the first entry.

ProTip™: Use Custom Front Matter

Any custom front matter that you specify will be available under page. For example, if you specify custom_css: true in a page’s front matter, that value will be available as page.custom_css.

If you specify front matter in a layout, access that via layout. For example, if you specify class: full_page in a layout’s front matter, that value will be available as layout.class in the layout and its parents.

Paginator

Variable	Description
paginator.page	The number of the current page
paginator.per_page	Number of posts per page
paginator.posts	Posts available for the current page
paginator.total_posts	Total number of posts
paginator.total_pages	Total number of pages
paginator.previous_page	The number of the previous page, or nil if no previous page exists
paginator.previous_page_path	The path to the previous page, or nil if no previous page exists
paginator.next_page	The number of the next page, or nil if no subsequent page exists
paginator.next_page_path	The path to the next page, or nil if no subsequent page exists
