Variables

Bunto traverses your site looking for files to process. Any files with YAML front matter are subject to processing. For each of these files, Bunto 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.
`layout`	Layout specific information + the YAML front matter. Custom variables set via the YAML 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 `bunto` 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 `bunto` 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 Bunto'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`. Bunto does not parse changes to `_config.yml` in `watch` mode, you must restart Bunto 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.

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.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.

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