--- title: Glossary of terms description: Terms commonly used throughout the documentation. keywords: [glossary] menu: docs: parent: getting-started weight: 60 weight: 60 type: glossary --- ### action See [template action](#template-action). ### archetype A template for new content. See [details](/content-management/archetypes/). ### argument A [scalar](#scalar), [array](#array), [slice](#slice), [map](#map), or [object](#object) passed to a [function](#function), [method](#method), or [shortcode](#shortcode). ### array A numbered sequence of elements. Unlike Go's [slice](#slice) data type, an array has a fixed length. 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. ### collection Typically, a collection of pages, but may also refer to an [array](#array), [slice](#slice), or [map](#map). For example, the pages within a site's "articles" section are a page collection. ### 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/). ### context Represented by a period "." 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). ### flag An option passed to a command-line program, beginning with one or two hyphens. See [details](/commands/hugo/). ### float See [floating point](#floating-point). ### floating point A numeric data type with a fractional component. For example, `3.14159`. ### 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/). ### front matter Metadata at the beginning of each content page, separated from the content by format-specific delimiters. See [details](/content-management/front-matter/). ### int See [integer](#integer). ### integer A numeric data type without a fractional component. For example, `42`. ### internationalization Software design and development efforts that enable [localization](#localization). See the [W3C definition](https://www.w3.org/International/questions/qa-i18n). Abbreviated i18n. ### kind See [page kind](#page-kind). ### layout See [template](#template). ### leaf bundle A [page bundle](#page-bundle) with an index.md file and zero or more [resources](#resource). Analogous to a physical leaf, a leaf bundle is at the end of a branch. Hugo ignores content (but not resources) beneath the leaf bundle. See [details](/content-management/page-bundles/). ### list page Any [page kind](#page-kind) that receives a page [collection](#collection) in [context](#context). This includes the home page, [section pages](#section-page), [taxonomy pages](#taxonomy-page), and [term pages](#term-page). ### localization Adaptation of a site to meet language and regional requirements. This includes translations, language-specific media, date and currency formats, etc. See [details](/content-management/multilingual/) and the [W3C definition](https://www.w3.org/International/questions/qa-i18n). Abbreviated l10n. ### map An unordered group of elements, each indexed by a unique key. See the [Go documentation](https://go.dev/ref/spec#Map_types) for details. ### method Used within a [template action](#template-action) and associated with an [object](#object), a method takes zero or more [arguments](#argument) and either returns a value or performs an action. For example, `.IsHome` is a method on the `.Page` object which returns `true` if the current page is the home page. See also [function](#function). ### module Like a [theme](#theme), a module is a packaged combination of [archetypes](#archetype), assets, content, data, [templates](#template), translations, or configuration settings. A module may serve as the basis for a new site, or to augment an existing site. See [details](/hugo-modules/). ### object A data structure with or without associated [methods](#method). ### page bundle A directory that encapsulates both content and associated [resources](#resource). There are two types of page bundles: [leaf bundles](/getting-started/glossary/#leaf-bundle) and [branch bundles](/getting-started/glossary/#branch-bundle). See [details](/content-management/page-bundles/). ### page kind A classification of rendered pages, one of "home", "page", "section", "taxonomy", or "term". Accessed via `.Page.Kind` in [templates](#template). See [details](/templates/section-templates/#page-kinds). ### pager Created during [pagination](#pagination), a pager contains a subset of a section list, and navigation links to other pagers. ### paginate To split a [section](#section) list into two or more [pagers](#pager) See [details](/templates/pagination/). ### pagination The process of [paginating](#paginate) a [section](#section) list. ### parameter Typically, a user-defined key/value pair at the site or page level, but may also refer to a configuration setting or an [argument](#argument). ### partial A [template](#template) called from any other template including [shortcodes](#shortcode), [render hooks](#render-hook), and other partials. A partial either renders something or returns something. A partial can also call itself, for example, to [walk](#walk) a data structure. ### permalink The absolute URL of a rendered page, including scheme and host. ### pipe See [pipeline](#pipeline). ### pipeline Within a [template action](#template-action), a pipeline is a possibly chained sequence of values, [function](#function) calls, or [method](#method) calls. Functions and methods in the pipeline may take multiple [arguments](#argument). A pipeline may be *chained* by separating a sequence of commands with pipeline characters "|". In a chained pipeline, the result of each command is passed as the last argument to the following command. The output of the final command in the pipeline is the value of the pipeline. See the [Go documentation](https://pkg.go.dev/text/template#hdr-Pipelines) for details. ### publish See [build](#build). ### regular page Content with the "page" [page kind](#page-kind). See also [section page](#section-page). ### render hook A [template](#template) that overrides standard markdown rendering. See [details](/templates/render-hooks/). ### resource Any file consumed by the build process to augment or generate content, structure, behavior, or presentation. For example: images, videos, content snippets, CSS, Sass, Javascript, and data. Hugo supports three types of resources: page resources (located in a [page bundle](/getting-started/glossary/#page-bundle)), global resources (located in the assets directory), and remote resources (typically accessed via https). ### scalar A single value, one of [string](#string), [integer](#integer), [floating point](#floating-point), or [boolean](#boolean). ### section A top-level content directory, or any content directory with an _index.md file. A content directory with an _index.md file is also known as a [branch bundle](/getting-started/glossary/#branch-bundle). Section templates receive one or more page [collections](#collection) in [context](#context). See [details](/content-management/sections/). ### section page Content with the "section" [page kind](#page-kind). Typically a listing of [regular pages](#regular-page) and/or [section pages](#section-page) within the current [section](#section). See also [regular page](#regular-page). ### shortcode A [template](#template) called from within markdown, taking zero or more [arguments](#argument). See [details](/content-management/shortcodes/). ### slice A numbered sequence of elements. Unlike Go's [array](#array) data type, slices are dynamically sized. See the [Go documentation](https://go.dev/ref/spec#Slice_types) for details. ### string A sequence of bytes. For example, `"What is 6 times 7?"` . ### taxonomy A group of related [terms](#term) used to classify content. For example, a "colors" taxonomy might include the terms "red", "green", and "blue". See [details](/content-management/taxonomies/). ### taxonomy page Content with the "taxonomy" [page kind](#page-kind). Typically a listing of [terms](#term) within a given [taxonomy](#taxonomy). ### template An HTML file with [template actions](#template-action), located within the layouts directory of a project, theme, or module. See [details](/templates/). ### template action A data evaluation or control structure within a [template](#template), delimited by "{{" and "}}". See the [Go documentation](https://pkg.go.dev/text/template#hdr-Actions) for details. ### term A member of a [taxonomy](#taxonomy), used to classify content. See [details](/content-management/taxonomies/). ### term page Content with the "term" [page kind](#page-kind). Typically a listing of [regular pages](#regular-page) and [section pages](#section-page) with a given [term](#term). ### theme A packaged combination of [archetypes](#archetype), assets, content, data, [templates](#template), translations, or configuration settings. A theme may serve as the basis for a new site, or to augment an existing site. See also [module](#module). ### token An identifier within a format string, beginning with a colon and replaced with a value when rendered. For example, use tokens in format strings for both [permalinks](/content-management/urls/#permalinks) and [dates](/functions/dateformat/#datetime-formatting-layouts). ### type See [content type](#content-type). ### variable A variable initialized within a [template action](#template-action). ### walk To recursively traverse a nested data structure. For example, rendering a multilevel menu.
