|
|
|
|
###### array
|
|
|
|
A numbered sequence of elements. Unlike Go's [slice](#slice) data type, an array has a fixed length. [Elements](#element) within an array can be [scalars](#scalar), slices, [maps](#map), pages, or other arrays. See the [Go documentation](https://go.dev/ref/spec#Array_types) for details.
|
|
|
|
###### bool
|
|
|
|
See [boolean](#boolean).
|
|
|
|
###### boolean
|
|
|
|
A data type with two possible values, either `true` or `false`.
|
|
|
|
###### branch bundle
|
|
|
|
A [page bundle](#page-bundle) with an _index.md file and zero or more [resources](#resource). Analogous to a physical branch, a branch bundle may have descendants including regular pages, [leaf bundles](/getting-started/glossary/#leaf-bundle), and other branch bundles. See [details](/content-management/page-bundles/).
|
|
|
|
###### build
|
|
|
|
To generate a static site that includes HTML files and assets such as images, CSS, and JavaScript. The build process includes rendering and resource transformations.
|
|
|
|
###### bundle
|
|
|
|
See [page bundle](#page-bundle).
|
|
|
|
###### cache
|
|
|
|
A software component that stores data so that future requests for the same data are faster.
|
|
|
|
###### chain
|
|
|
|
Within a template, to connect one or more [identifiers](#identifier) with a dot. An identifier can represent a method, object, or field. For example, `.Site.Params.author.name` or `.Date.UTC.Hour`.
|
|
|
|
###### collection
|
|
|
|
An [array](#array), [slice](#slice), or [map](#map).
|
|
|
|
###### content format
|
|
|
|
A markup language for creating content. Typically markdown, but may also be HTML, AsciiDoc, Org, Pandoc, or reStructuredText. See [details](/content-management/formats/).
|
|
|
|
###### content type
|
|
|
|
A classification of content inferred from the top-level directory name or the `type` set in [front matter](#front-matter). Pages in the root of the content directory, including the home page, are of type "page". Accessed via `.Page.Type` in [templates](#template). See [details](/content-management/types/).
|
|
|
|
###### content view
|
|
|
|
A template called with the `.Page.Render` method. See [details](/templates/views/).
|
|
|
|
###### context
|
|
|
|
Represented by a dot "." within a [template action](#template-action), context is the current location in a data structure. For example, while iterating over a [collection](#collection) of pages, the context within each iteration is the page's data structure. The context received by each template depends on template type and/or how it was called. See [details](/templates/introduction/#the-dot).
|
|
|
|
###### default sort order
|
|
|
|
The default sort order for page collections. Hugo sorts by [weight](#weight), then by date (descending), then by link title, and then by file path.
|
|
|
|
###### element
|
|
|
|
A member of a slice or array.
|
|
|
|
###### environment
|
|
|
|
Typically one of `development`, `staging`, or `production`, each environment may exhibit different behavior depending on configuration and template logic. For example, in a production environment you might minify and fingerprint CSS, but that probably doesn't make sense in a development environment.
|
|
|
|
When running the built-in development server with the `hugo server` command, the environment is set to `development`. When building your site with the `hugo` command, the environment is set to `production`. To override the environment value, use the `--environment` command line flag.
|
|
|
|
To determine the current environment within a template, use the [`hugo.Environment`] function.
|
|
|
|
[`hugo.Environment`]: /functions/hugo/environment
|
|
|
|
###### field
|
|
|
|

|
|
|
|
###### fragment
|

|
|
The final segment of a URL, beginning with a hash (`#`) mark, that references an `id` attribute of an HTML element on the page.
|
|
|
|
###### front matter
|
|
|
|
Metadata at the beginning of each content page, separated from the content by format-specific delimiters. See [details](/content-management/front-matter/).
|
|
|
|
###### function
|
|
|
|
Used within a [template action](#template-action), a function takes one or more [arguments](#argument) and returns a value. Unlike [methods](#method), functions are not associated with an [object](#object). See [details](/functions/).
|
|
|
|
###### global resource
|
|
|
|
A file within the assets directory, or within any directory [mounted](/hugo-modules/configuration/#module-configuration-mounts) to the assets directory. Capture one or more global resources using the [`resources.Get`], [`resources.GetMatch`], [`resources.Match`], or [`resources.ByType`] functions.

|
|
|
###### interval
|
|
|
|
An [interval](https://en.wikipedia.org/wiki/Interval_(mathematics)) is a range of numbers between two endpoints: closed, open, or half-open.
|
|
|
|
- A _closed_ interval, denoted by brackets, includes its endpoints. For example, [0, 1] is the interval where `0 <= x <= 1`.
|
|
|
|
- An _open_ interval, denoted by parentheses, excludes its endpoints. For example, (0, 1) is the interval where `0 < x < 1`.
|
|
|
|
- A _half-open_ interval includes only one of its endpoints. For example, (0, 1] is the _left-open_ interval where `0 < x <= 1`, while [0, 1) is the _right-open_ interval where `0 <= x < 1`.

|
|
|
|
Note that there are also `RSS`, `sitemap`, `robotsTXT`, and `404` page kinds, but these are only available during the rendering of each of these respective page's kind and therefore *not* available in any of the `Pages` collections.
