**Front matter** allows you to keep metadata attached to an instance of a [content type][]---i.e., embedded inside a content file---and is one of the many features that gives Hugo its strength.
|
|
|
|
{{< youtube Yh2xKRJGff4 >}}
|
|
|
|
## Front Matter Formats
|
|
|
|
Hugo supports three formats for front matter, each with their own identifying tokens.
|
|
|
|
TOML
|
|
: identified by opening and closing `+++`.
|
|
|
|
YAML
|
|
: identified by opening and closing `---`.
|
|
|
|
JSON
|
|
: a single JSON object surrounded by '`{`' and '`}`', followed by a new line.
|
|
|
|
### Example
|
|
|
|
{{< code-toggle >}}
|
|
+++
|
|
title = "spf13-vim 3.0 release and new website"
|
|
description = "spf13-vim is a cross platform distribution of vim plugins and resources for Vim."
|
|
tags = [ ".vimrc", "plugins", "spf13-vim", "vim" ]
|
|
date = "2012-04-06"
|
|
categories = [
|
|
"Development",
|
|
"VIM"
|
|
]
|
|
slug = "spf13-vim-3-0-release-and-new-website"
|
|
+++
|
|
{{</ code-toggle >}}
|
|
|
|
## Front Matter Variables
|
|
|
|
### Predefined
|
|
|
|
There are a few predefined variables that Hugo is aware of. See [Page Variables][pagevars] for how to call many of these predefined variables in your templates.
|
|
|
|
aliases
|
|
: an array of one or more aliases (e.g., old published paths of renamed content) that will be created in the output directory structure . See [Aliases][aliases] for details.
|
|
|
|
audio
|
|
: an array of paths to audio files related to the page; used by the `opengraph` [internal template](/templates/internal) to populate `og:audio`.
|
|
|
|
date
|
|
: the datetime at which the content was created; note this value is auto-populated according to Hugo's built-in [archetype][].
|
|
|
|
description
|
|
: the description for the content.
|
|
|
|
draft
|
|
: if `true`, the content will not be rendered unless the `--buildDrafts` flag is passed to the `hugo` command.
|
|
|
|
expiryDate
|
|
: the datetime at which the content should no longer be published by Hugo; expired content will not be rendered unless the `--buildExpired` flag is passed to the `hugo` command.
|
|
|
|
headless
|
|
: if `true`, sets a leaf bundle to be [headless][headless-bundle].
|
|
|
|
images
|
|
: an array of paths to images related to the page; used by [internal templates](/templates/internal) such as `_internal/twitter_cards.html`.
|
|
|
|
isCJKLanguage
|
|
: if `true`, Hugo will explicitly treat the content as a CJK language; both `.Summary` and `.WordCount` work properly in CJK languages.
|
|
|
|
keywords
|
|
: the meta keywords for the content.
|
|
|
|
layout
|
|
: the layout Hugo should select from the [lookup order][lookup] when rendering the content. If a `type` is not specified in the front matter, Hugo will look for the layout of the same name in the layout directory that corresponds with a content's section. See ["Defining a Content Type"][definetype]
|
|
|
|
lastmod
|
|
: the datetime at which the content was last modified.
|
|
|
|
linkTitle
|
|
: used for creating links to content; if set, Hugo defaults to using the `linktitle` before the `title`. Hugo can also [order lists of content by `linktitle`][bylinktitle].
|
|
|
|
markup
|
|
: **experimental**; specify `"rst"` for reStructuredText (requires`rst2html`) or `"md"` (default) for Markdown.
|
|
|
|
outputs
|
|
: allows you to specify output formats specific to the content. See [output formats][outputs].
|
|
|
|
publishDate
|
|
: if in the future, content will not be rendered unless the `--buildFuture` flag is passed to `hugo`.
|
|
|
|
resources
|
|
: used for configuring page bundle resources. See [Page Resources][page-resources].
|
|
|
|
series
|
|
: an array of series this page belongs to, as a subset of the `series` [taxonomy](/content-management/taxonomies/); used by the `opengraph` [internal template](/templates/internal) to populate `og:see_also`.
|
|
|
|
slug
|
|
: appears as the tail of the output URL. A value specified in front matter will override the segment of the URL based on the filename.
|
|
|
|
title
|
|
: the title for the content.
|
|
|
|
type
|
|
: the type of the content; this value will be automatically derived from the directory (i.e., the [section][]) if not specified in front matter.
|
|
|
|
url
|
|
: the full path to the content from the web root. It makes no assumptions about the path of the content file. It also ignores any language prefixes of
|
|
the multilingual feature.
|
|
|
|
videos
|
|
: an array of paths to videos related to the page; used by the `opengraph` [internal template](/templates/internal) to populate `og:video`.
|
|
|
|
weight
|
|
: used for [ordering your content in lists][ordering]. Lower weight gets higher precedence. So content with lower weight will come first.
|
|
|
|
\<taxonomies\>
|
|
: field name of the *plural* form of the index. See `tags` and `categories` in the above front matter examples. _Note that the plural form of user-defined taxonomies cannot be the same as any of the predefined front matter variables._
|
|
|
|
{{% note "Hugo's Default URL Destinations" %}}
|
|
If neither `slug` nor `url` is present and [permalinks are not configured otherwise in your site `config` file](/content-management/urls/#permalinks), Hugo will use the filename of your content to create the output URL. See [Content Organization](/content-management/organization) for an explanation of paths in Hugo and [URL Management](/content-management/urls/) for ways to customize Hugo's default behaviors.
|
|
{{% /note %}}
|
|
|
|
### User-Defined
|
|
|
|
You can add fields to your front matter arbitrarily to meet your needs. These user-defined key-values are placed into a single `.Params` variable for use in your templates.
|
|
|
|
The following fields can be accessed via `.Params.include_toc` and `.Params.show_comments`, respectively. The [Variables][] section provides more information on using Hugo's page- and site-level variables in your templates.
|
|
|
|
{{< code-toggle copy="false" >}}
|
|
include_toc: true
|
|
show_comments: false
|
|
{{</ code-toggle >}}
|
|
|
|
|
|
## Order Content Through Front Matter
|
|
|
|
You can assign content-specific `weight` in the front matter of your content. These values are especially useful for [ordering][ordering] in list views. You can use `weight` for ordering of content and the convention of [`<TAXONOMY>_weight`][taxweight] for ordering content within a taxonomy. See [Ordering and Grouping Hugo Lists][lists] to see how `weight` can be used to organize your content in list views.
|
|
|
|
## Override Global Markdown Configuration
|
|
|
|
It's possible to set some options for Markdown rendering in a content's front matter as an override to the [BlackFriday rendering options set in your project configuration][config].
