Variables

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

Global Variables

Variable	Description
site	Sitewide information + configuration settings from _config.yml. See below for details.
page	Page specific information + the YAML front matter. Custom variables set via the YAML Front Matter will be available here. See below for details.
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 three properties: path, modified_time 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.
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.[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 url: http://mysite.com in your configuration file, then in your Posts and Pages it will be stored in site.url. 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 the Page.
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 the Post (useful in RSS feeds). e.g. /2008/12/14/my-post
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 YAML Front Matter.
page.tags	The list of tags to which this post belongs. These can be specified in the YAML Front Matter.
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 YAML 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.

Paginator

Variable	Description
paginator.per_page	Number of Posts per page.
paginator.posts	Posts available for that page.
paginator.total_posts	Total number of Posts.
paginator.total_pages	Total number of Pages.
paginator.page	The number of the current page.
paginator.previous_page	The number of the previous page.
paginator.previous_page_path	The path to the previous page.
paginator.next_page	The number of the next page.
paginator.next_page_path	The path to the next page.

Paginator variable availability

These are only available in index files, however they can be located in a subdirectory, such as /blog/index.html.
