To avoid setting the build options on every testimonials, one can use [`cascade`]({{< relref "/content-management/front-matter#front-matter-cascade" >}}) on the testimonial section's content file.

{{% note "Lazy Blogger"%}}
If all you want is a simple menu for your sections, see the ["Section Menu for Lazy Bloggers" in Menu Templates](/templates/menu-templates/#section-menu-for-lazy-bloggers).
{{% /note %}}
## Overview
You can do this:
To create a menu for your site:
* Place content in one or many menus
* Handle nested menus with unlimited depth
* Create menu entries without being attached to any content
* Distinguish active element (and active branch)
1. Define the menu entries
2. [Localize] each entry
3. Render the menu with a [template]
## What is a Menu in Hugo?
Create multiple menus, either flat or nested. For example, create a main menu for the header, and a separate menu for the footer.
A **menu** is a named array of menu entries accessible by name via the [`.Site.Menus` site variable][sitevars]. For example, you can access your site's `main` menu via `.Site.Menus.main`.
There are three ways to define menu entries:
{{% note "Menus on Multilingual Sites" %}}
If you make use of the [multilingual feature](/content-management/multilingual/), you can define language-independent menus.
{{% /note %}}
See the [Menu Entry Properties][me-props] for all the variables and functions related to a menu entry.
## Add content to menus
Hugo allows you to add content to a menu via the content's [front matter](/content-management/front-matter/).
### Simple
If all you need to do is add an entry to a menu, the simple form works well.
#### A Single Menu
{{< code-toggle >}}
menu: "main"
{{< /code-toggle >}}
#### Multiple Menus
{{< code-toggle >}}
menu: ["main", "footer"]
{{< /code-toggle >}}
#### Advanced
{{< code-toggle >}}
menu:
docs:
parent: 'extras'
weight: 20
{{< /code-toggle >}}
## Add Non-content Entries to a Menu
You can also add entries to menus that arent attached to a piece of content. This takes place in your Hugo project's [`config` file][config] (see [Menu Entry Properties][me-props] for full details of available variables).
Heres an example snippet pulled from a configuration file:
{{< code-toggle file="config" >}}
[[menu.main]]
name = "about hugo"
pre = "<i class='fa fa-heart'></i>"
weight = -110
identifier = "about"
url = "/about/"
[[menu.main]]
name = "getting started"
pre = "<i class='fa fa-road'></i>"
post = "<span class='alert'>New!</span>"
weight = -100
url = "/getting-started/"
{{< /code-toggle >}}
1. Automatically
1. In front matter
1. In site configuration
{{% note %}}
The URLs must be relative to the context root. If the `baseURL` is `https://example.com/mysite/`, then the URLs in the menu must not include the context root `mysite`. Using an absolute URL will override the baseURL. If the value used for `URL` in the above example is `https://subdomain.example.com/`, the output will be `https://subdomain.example.com`.
Although you can use these methods in combination when defining a menu, the menu will be easier to conceptualize and maintain if you use one method throughout the site.
{{% /note %}}
## Nesting
## Define automatically
All nesting of content is done via the `parent` field.
To automatically define menu entries for each top-level section of your site, enable the section pages menu in your site configuration.
The parent of an entry should be the identifier of another entry. The identifier should be unique (within a menu).
{{< code-toggle file="config" copy=false >}}
sectionPagesMenu = "main"
{{< /code-toggle >}}
The following order is used to determine an Identifier:
This creates a menu structure that you can access with `site.Menus.main` in your templates. See [menu templates] for details.
`.Name > .LinkTitle > .Title`
## Define in front matter
This means that `.Title` will be used unless `.LinkTitle` is present, etc. In practice, `.Name` and `.Identifier` are only used to structure relationships and therefore never displayed.
To add a page to the "main" menu:
In this example, the top level of the menu is defined in your [site `config` file][config]. All content entries are attached to one of these entries via the `.Parent` field.
{{< code-toggle file="content/about.md" copy=false fm=true >}}
title = 'About'
menu = 'main'
{{< /code-toggle >}}
## Params
Access the entry with `site.Menus.main` in your templates. See [menu templates] for details.
You can also add user-defined content to menu items via the `params` field.
To add a page to the "main" and "footer" menus:
A common use case is to define a custom param to add a css class to a specific menu item.
{{< code-toggle file="content/contact.md" copy=false fm=true >}}
title = 'Contact'
menu = ['main','footer']
{{< /code-toggle >}}
{{< code-toggle file="config" >}}
Access the entry with `site.Menus.main` and `site.Menus.footer` in your templates. See [menu templates] for details.
### Properties {#properties-front-matter}
Use these properties when defining menu entries in front matter:
identifier
: (`string`) Required when two or more menu entries have the same `name`, or when localizing the `name` using translation tables. Must start with a letter, followed by letters, digits, or underscores.
name
: (`string`) The text to display when rendering the menu entry.
params
: (`map`) User-defined properties for the menu entry.
parent
: (`string`) The `identifier` of the parent menu entry. If `identifier` is not defined, use `name`. Required for child entries in a nested menu.
post
: (`string`) The HTML to append when rendering the menu entry.
pre
: (`string`) The HTML to prepend when rendering the menu entry.
title
: (`string`) The HTML `title` attribute of the rendered menu entry.
weight
: (`int`) A non-zero integer indicating the entry's position relative the root of the menu, or to its parent for a child entry. Lighter entries float to the top, while heavier entries sink to the bottom.
### Example {#example-front-matter}
This front matter menu entry demonstrates some of the available properties:
{{< code-toggle file="content/products/software.md" copy=false fm=true >}}
title = 'Software'
[menu.main]
parent = 'Products'
weight = 20
pre = '<i class="fa-solid fa-code"></i>'
[menu.main.params]
class = 'center'
{{< /code-toggle >}}
Access the entry with `site.Menus.main` in your templates. See [menu templates] for details.
## Define in site configuration
To define entries for the "main" menu:
{{< code-toggle file="config" copy=false >}}
[[menu.main]]
name = "about hugo"
pre = "<i class='fa fa-heart'></i>"
weight = -110
identifier = "about"
url = "/about/"
[menu.main.params]
class = "highlight-menu-item"
{{</ code-toggle >}}
name = 'Home'
pageRef = '/'
weight = 10
## Render Menus
[[menu.main]]
name = 'Products'
pageRef = '/products'
weight = 20
See [Menu Templates](/templates/menu-templates/) for information on how to render your site menus within your templates.
[[menu.main]]
name = 'Services'
pageRef = '/services'
weight = 30
{{< /code-toggle >}}
[config]: /getting-started/configuration/
[multilingual]: /content-management/multilingual/
[sitevars]: /variables/
[me-props]: /variables/menus/
This creates a menu structure that you can access with `site.Menus.main` in your templates. See [menu templates] for details.
To define entries for the "footer" menu:
{{< code-toggle file="config" copy=false >}}
[[menu.footer]]
name = 'Terms'
pageRef = '/terms'
weight = 10
[[menu.footer]]
name = 'Privacy'
pageRef = '/privacy'
weight = 20
{{< /code-toggle >}}
This creates a menu structure that you can access with `site.Menus.footer` in your templates. See [menu templates] for details.
### Properties {#properties-site-configuration}
{{% note %}}
The [properties available to entries defined in front matter] are also available to entries defined in site configuration.
[properties available to entries defined in front matter]: /content-management/menus/#properties-front-matter
{{% /note %}}
Each menu entry defined in site configuration requires two or more properties:
- Specify `name` and `pageRef` for internal links
- Specify `name` and `url` for external links
pageRef
: (`string`) The file path of the target page, relative to the `content` directory. Omit language code and file extension. Required for *internal* links.
Kind|pageRef
:--|:--
home|`/`
page|`/books/book-1`
section|`/books`
taxonomy|`/tags`
term|`/tags/foo`
url
: (`string`) Required for *external* links.
### Example {#example-site-configuration}
This nested menu demonstrates some of the available properties:
{{< code-toggle file="config" copy=false >}}
[[menu.main]]
name = 'Products'
pageRef = '/products'
weight = 10

### Changes in Hugo 0.112.0
{{< new-in "0.112.0" >}}
In version `0.112.0` of Hugo we did a major we consolidated all configuration options, but also improved how the languages and their params gets merged with the main configuration. But while testing this on Hugo sites out there, we got some error reports.
1. `site.Language.Params` is deprecated. Use `site.Params` directly.
1. The `params` sections on site and language is the only place to put custom user parameters, and `site.Params` will only contain these user defined parameters (see example below).
```toml
title = "My blog"
languageCode = "en-us"
[languages]
[languages.sv]
title = "Min blogg"
languageCode = "sv"
[languages.en.params]
color = "blue"
```
In the example above, all the settings exept the `color` below `params` maps to predefined configuration options in Hguo for the site and its language, and should be accessed via the documented accessors:
```
{{ site.Title }}
{{ site.LanguageCode }}
{{ site.Params.color }}

## Menus
You can define your menus for each language independently. Creating multilingual menus works just like [creating regular menus][menus], except they're defined in language-specific blocks in the configuration file:
Localization of menu entries depends on the how you define them:
{{< code-toggle file="config" >}}
defaultContentLanguage = "en"
- When you define menu entries [automatically] using the section pages menu, you must use translation tables to localize each entry.
- When you define menu entries [in front matter], they are already localized based on the front matter itself. If the front matter values are insufficient, use translation tables to localize each entry.
- When you define menu entries [in site configuration], you can (a) use translation tables, or (b) create language-specific menu entries under each language key.
[languages.en]
weight = 0
languageName = "English"
### Use translation tables
[[languages.en.menu.main]]
url = "/"
name = "Home"
weight = 0
[languages.de]
weight = 10
languageName = "Deutsch"
[[languages.de.menu.main]]
url = "/"
name = "Startseite"
weight = 0
{{< /code-toggle >}}
The rendering of the main navigation works as usual. `.Site.Menus` will just contain the menu in the current language. Note that `absLangURL` below will link to the correct locale of your website. Without it, menu entries in all languages would link to the English version, since it's the default content language that resides in the root directory.
When rendering the text that appears in menu each entry, the [example menu template] does this:
```go-html-template
<ul>
{{- $currentPage := . -}}
{{ range .Site.Menus.main -}}
<li class="{{ if $currentPage.IsMenuCurrent "main" . }}active{{ end }}">
<a href="{{ .URL | absLangURL }}">{{ .Name }}</a>
</li>
{{- end }}
</ul>
{{ or (T .Identifier) .Name | safeHTML }}
```
### Dynamically localizing menus with i18n
It queries the translation table for the current language using the menu entry's `identifier` and returns the translated string. If the translation table does not exist, or if the `identifier` key is not present in the translation table, it falls back to `name`.
While customizing menus per language is useful, your config file can become hard to maintain if you have a lot of languages
The `identifier` depends on how you define menu entries:
If your menus are the same in all languages (ie. if the only thing that changes is the translated name) you can use the `.Identifier` as a translation key for the menu name:
- If you define the menu entry [automatically] using the section pages menu, the `identifier` is the page's `.Section`.
- If you define the menu entry [in site configuration] or [in front matter], set the `identifier` property to the desired value.
{{< code-toggle file="config" >}}
For example, if you define menu entries in site configuration:
{{< code-toggle file="config" copy=false >}}
[[menu.main]]
name = "About me"
url = "about"
identifier = 'products'
name = 'Products'
pageRef = '/products'
weight = 10
[[menu.main]]
identifier = 'services'
name = 'Services'
pageRef = '/services'
weight = 20
{{< / code-toggle >}}
Create corresponding entries in the translation tables:
{{< code-toggle file="i18n/de" copy=false >}}
products = 'Produkte'
services = 'Leistungen'
{{< / code-toggle >}}
[example menu template]: /templates/menu-templates/#example
[automatically]: /content-management/menus/#define-automatically
[in front matter]: /content-management/menus/#define-in-front-matter
[in site configuration]: /content-management/menus/#define-in-site-configuration
### Create language-specific menu entries
For example:
{{< code-toggle file="config" copy=false >}}
[languages.de]
languageCode = 'de-DE'
languageName = 'Deutsch'
weight = 1
identifier = "about"
[[languages.de.menu.main]]
name = 'Produkte'
pageRef = '/products'
weight = 10
[[languages.de.menu.main]]
name = 'Leistungen'
pageRef = '/services'
weight = 20
[languages.en]
languageCode = 'en-US'
languageName = 'English'
weight = 2
[[languages.en.menu.main]]
name = 'Products'
pageRef = '/products'
weight = 10
[[languages.en.menu.main]]
name = 'Services'
pageRef = '/services'
weight = 20
{{< /code-toggle >}}
You now need to specify the translations for the menu keys in the i18n files:
{{< code file="i18n/pt.toml" >}}
[about]
other="Sobre mim"
{{< /code >}}
And do the appropriate changes in the menu code to use the `i18n` tag with the `.Identifier` as a key. You will also note that here we are using a `default` to fall back to `.Name`, in case the `.Identifier` key is also not present in the language specified in the `defaultContentLanguage` configuration.
{{< code file="layouts/partials/menu.html" >}}
<ul>
{{- $currentPage := . -}}
{{ range .Site.Menus.main -}}
<li class="{{ if $currentPage.IsMenuCurrent "main" . }}active{{ end }}">
<a href="{{ .URL | absLangURL }}">{{ i18n .Identifier | default .Name}}</a>
</li>
{{- end }}
</ul>
{{< /code >}}
For a simple menu with two languages, these menu entries are easy to create and maintain. For a larger menu, or with more than two languages, using translation tables as described above is preferable.

Hugo assumes that your content is organized with a purpose. The same structure that you use to organize your source content is used to organize the rendered site. As displayed above, the organization of the source content will be mirrored at the destination.
There are times when you may need more fine-grained control over the content organization. In such cases, the front matter field can be used to determine the destination of a specific piece of content.
The following items are defined in a specific order for a reason: items explained lower down in the list override higher items. Note that not all items can be defined in front matter.
### `filename`
`filename` is not a front matter field. It is the actual file name, minus the extension. This will be the name of the file in the destination (e.g., `content/posts/my-post.md` becomes `example.com/posts/my-post/`).
### `slug`
When defined in the front matter, the `slug` can take the place of the filename in the destination.
{{< code file="content/posts/old-post.md" >}}
---
title: A new post with the filename old-post.md
slug: "new-post"
---
{{< /code >}}
This will render to the following destination according to Hugo's default behavior:
```txt
example.com/posts/new-post/
```
### `section`
`section` is determined by a content item's location on disk and *cannot* be specified in the front matter. See [sections] for more information.
### `type`
A content item's `type` is also determined by its location on disk but, unlike `section`, it *can* be specified in the front matter. See [types]. This can come in especially handy when you want a piece of content to render using a different layout. In the following example, you can create a layout at `layouts/new/mylayout.html` that Hugo will use to render this piece of content, even in the midst of many other posts.
{{< code file="content/posts/my-post.md" >}}
---
title: My Post
type: new
layout: mylayout
---
{{< /code >}}
<!-- See https://discourse.gohugo.io/t/path-not-works/6387 -->
<!-- ### `path`-->
<!--`path` can be provided in the front matter. This will replace the actual path to the file on disk. Destination will create the destination with the same path, including the section. -->
### `url`
A complete URL can be provided. This will override all the above as it pertains to the end destination. This must be the path from the baseURL (starting with a `/`). `url` will be used exactly as it is defined in the front matter, and will ignore the `--uglyURLs` setting in your site configuration:
{{< code file="content/posts/old-url.md" >}}
---
title: Old URL
url: /blog/new-url/
---
{{< /code >}}
Assuming your `baseURL` is [configured][config] to `https://example.com`, the addition of `url` to the front matter will make `old-url.md` render to the following destination:
```txt
https://example.com/blog/new-url/
```
You can see more information on how to control output paths in [URL Management][urls].
The `url` is the entire URL path, defined by the file path and optionally overridden by a `url` value in front matter. See [URL Management](/content-management/urls/#slug) for details.

The `Related` method takes one argument which may be a `Page` or a options map. The options map have these options:
Here is the list of "Related" methods available on a page collection such `.RegularPages`.
indices

#### .Related PAGE
document

A fictional example using all of the above options:
```go-html-template
{{ $related := site.RegularPages.Related . }}
```
#### .RelatedIndices PAGE INDICE1 [INDICE2 ...]
Returns a collection of pages related to a given one restricted to a list of indices.
```go-html-template
{{ $related := site.RegularPages.RelatedIndices . "tags" "date" }}
```
#### .RelatedTo KEYVALS [KEYVALS2 ...]
Returns a collection of pages related together by a set of indices and their match.
In order to build those set and pass them as argument, one must use the `keyVals` function where the first argument would be the `indice` and the consecutive ones its potential `matches`.
```go-html-template
{{ $related := site.RegularPages.RelatedTo ( keyVals "tags" "hugo" "rocks") ( keyVals "date" .Date ) }}
{{ $page := . }}
{{ $opts :=
"indices" (slice "tags" "keywords")

Read [this blog article](https://regisphilibert.com/blog/2018/04/hugo-optmized-relashionships-with-related-content/) for a great explanation of more advanced usage of this feature.
We improved and simplified this feature in Hugo 0.111.0. Before this we had 3 different methods: `Related`, `RelatedTo` and `RelatedIndicies`. Now we have only one method: `Related`. The old methods are still available but deprecated. Also see [this blog article](https://regisphilibert.com/blog/2018/04/hugo-optmized-relashionships-with-related-content/) for a great explanation of more advanced usage of this feature.

## Index Content Headings in Related Content
{{< new-in "0.111.0" >}}
Hugo can index the headings in your content and use this to find related content. You can enable this by adding a index of type `fragments` to your `related` configuration:
{{< code-toggle file="config" copy=false >}}
[related]
threshold = 20
includeNewer = true
toLower = false
[[related.indices]]
name = "fragmentrefs"
type = "fragments"
applyFilter = false
weight = 80
{{< /code-toggle >}}
* The `name` maps to a optional front matter slice attribute that can be used to link from the page level down to the fragment/heading level.
* If `applyFilter`is enabled, the `.HeadingsFiltered` on each page in the result will reflect the filtered headings. This is useful if you want to show the headings in the related content listing:
```go-html-template
{{ $related := .Site.RegularPages.Related . | first 5 }}
{{ with $related }}
<h2>See Also</h2>
<ul>
{{ range $i, $p := . }}
<li>
<a href="{{ .RelPermalink }}">{{ .Title }}</a>
{{ with .HeadingsFiltered }}
<ul>
{{ range . }}
{{ $link := printf "%s#%s" $p.RelPermalink .ID | safeURL }}
<li>
<a href="{{ $link }}">{{ .Title }}</a>
</li>
{{ end }}
</ul>
{{ end }}
</li>
{{ end }}
</ul>
{{ end }}
```

Setting "2006" (default value for date indexes) as the pattern for a date index will add weight to pages published in the same year. For busier blogs, "200601" (year and month) may be a better default.

### `gist`
Bloggers often want to include GitHub gists when writing posts. Let's suppose we want to use the [gist at the following url][examplegist]:
To display a GitHub [gist] with this URL:
```txt
https://gist.github.com/spf13/7896402
[gist]: https://docs.github.com/en/get-started/writing-on-github/editing-and-sharing-content-with-gists
```text
https://gist.github.com/user/50a7482715eac222e230d1e64dd9a89b
```
We can embed the gist in our content via username and gist ID pulled from the URL:
Include this in your markdown:
```go-html-template
{{</* gist spf13 7896402 */>}}
```text
{{</* gist user 50a7482715eac222e230d1e64dd9a89b */>}}
```
#### Example `gist` Input
This will display all files in the gist alphabetically by file name.
If the gist contains several files and you want to quote just one of them, you can pass the filename (quoted) as an optional third argument:
{{< gist jmooring 50a7482715eac222e230d1e64dd9a89b >}}
{{< code file="gist-input.md" >}}
{{</* gist spf13 7896402 "img.html" */>}}

### `highlight`
This shortcode will convert the source code provided into syntax-highlighted HTML. Read more on [highlighting](/content-management/syntax-highlighting/). `highlight` takes exactly one required `language` parameter and requires a closing shortcode.
To display a highlighted code sample:
#### Example `highlight` Input
{{< code file="content/tutorials/learn-html.md" >}}
{{</* highlight html */>}}
<section id="main">

If you'd like to embed a photo from [Instagram], you only need the photo's ID. You can discern an Instagram photo ID from the URL:
The `instagram` shortcode uses Facebook's **oEmbed Read** feature. The Facebook [developer documentation] states:
```txt

## Permalinks
## Overview
The default Hugo target directory for your built website is `public/`. However, you can change this value by specifying a different `publishDir` in your [site configuration][config]. The directories created at build time for a section reflect the position of the content's directory within the `content` folder and namespace matching its layout within the `contentdir` hierarchy.
By default, when Hugo renders a page, the resulting URL matches the file path within the `content` directory. For example:
The `permalinks` option in your [site configuration][config] allows you to adjust the directory paths (i.e., the URLs) on a per-section basis. This will change where the files are written to and will change the page's internal "canonical" location, such that template references to `.RelPermalink` will honor the adjustments made as a result of the mappings in this option.
```text
content/posts/post-1.md → https://example.org/posts/post-1/
```
{{% note "Default Publish and Content Folders" %}}
These examples use the default values for `publishDir` and `contentDir`; i.e., `public` and `content`, respectively. You can override the default values in your [site's `config` file](/getting-started/configuration/).
You can change the structure and appearance of URLs with front matter values and site configuration options.
## Front matter
### `slug`
Set the `slug` in front matter to override the last segment of the path. The `slug` value does not affect section pages.
{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}}
title = 'My First Post'
slug = 'my-first-post'
{{< /code-toggle >}}
The resulting URL will be:
```text
https://example.org/posts/my-first-post/
```
### `url`
Set the `url` in front matter to override the entire path. Use this with either regular pages or section pages.
With this front matter:
{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}}
title = 'My First Article'
url = '/articles/my-first-article'
{{< /code-toggle >}}
The resulting URL will be:
```text
https://example.org/articles/my-first-article/
```
If you include a file extension:
{{< code-toggle file="content/posts/post-1.md" copy=false fm=true >}}
title = 'My First Article'
url = '/articles/my-first-article.html'
{{< /code-toggle >}}
The resulting URL will be:
```text
https://example.org/articles/my-first-article.html
```
In a monolingual site, a `url` value with or without a leading slash is relative to the `baseURL`.
In a multilingual site:
- A `url` value with a leading slash is relative to the `baseURL`.
- A `url` value without a leading slash is relative to the `baseURL` plus the language prefix.
Site type|Front matter `url`|Resulting URL
:--|:--|:--
monolingual|`/about`|`https://example.org/about/`
monolingual|`about`|`https://example.org/about/`
multilingual|`/about`|`https://example.org/about/`
multilingual|`about`|`https://example.org/de/about/`
If you set both `slug` and `url` in front matter, the `url` value takes precedence.
## Site configuration
### Permalinks
In your site configuration, set a URL pattern for regular pages within a top-level section. This is recursive, affecting descendant regular pages.
{{% note %}}
The `permalinks` defined in your site configuration do not apply to section pages. To adjust the URL for section pages, set `url` in front matter.
{{% /note %}}
For example, if one of your [sections] is called `posts` and you want to adjust the canonical path to be hierarchical based on the year, month, and post title, you could set up the following configurations in YAML and TOML, respectively.
#### Examples {#permalinks-examples}
### Permalinks Configuration Example
With this content structure:
{{< code-toggle file="config" copy="false" >}}
permalinks:
posts: /:year/:month/:title/
```text
content/
├── posts/
│   ├── _index.md
│   ├── post-1.md
│   └── post-2.md
└── _index.md
```
Create a date-based hierarchy, recursively, for regular pages within the `posts` section:
{{< code-toggle file="config" copy=false >}}
[permalinks]
posts = '/posts/:year/:month/:title/'
{{< /code-toggle >}}
Only the content under `posts/` will have the new URL structure. For example, the file `content/posts/sample-entry.md` with `date: 2017-02-27T19:20:00-05:00` in its front matter will render to `public/2017/02/sample-entry/index.html` at build time and therefore be reachable at `https://example.com/2017/02/sample-entry/`.
The structure of the published site will be:
To configure the `permalinks` option for pages in the "root" section, use **/** as the key:
```text
public/
├── posts/
│   ├── 2023/
│   │   └── 03/
│   │   ├── post-1/
│   │   │   └── index.html
│   │   └── post-2/
│   │   └── index.html
│   └── index.html
├── favicon.ico
└── index.html
```
{{< code-toggle file="config" copy="false" >}}
permalinks:
/: /:year/:month/:filename/
To create a date-based hierarchy for regular pages in the content root:
{{< code-toggle file="config" copy=false >}}
[permalinks]
'/' = '/:year/:month/:title/'
{{< /code-toggle >}}
If the standard date-based permalink configuration does not meet your needs, you can also format URL segments using [Go time formatting directives](https://pkg.go.dev/time#Time.Format). For example, a URL structure with two digit years and month and day digits without zero padding can be accomplished with:
{{% note %}}
A URL pattern defined for the content root is not recursive.
{{% /note %}}
{{< code-toggle file="config" copy="false" >}}
permalinks:
posts: /:06/:1/:2/:title/
Use the same approach with taxonomies. For example, to omit the taxonomy segment of the URL:
{{< code-toggle file="config" copy=false >}}
[permalinks]
'tags' = '/:title/'
{{< /code-toggle >}}
You can also configure permalinks of taxonomies with the same syntax, by using the plural form of the taxonomy instead of the section. You will probably only want to use the configuration values `:slug` or `:title`.
Front matter `url` values take precedence over URL patterns defined in `permalinks`.
### Permalink Configuration Values
#### Tokens
The following is a list of values that can be used in a `permalink` definition in your site `config` file. All references to time are dependent on the content's date.
Use these tokens when defining the URL pattern. The `date` field in front matter determines the value of time-related tokens.
`:year`
: the 4-digit year
@ -93,219 +194,157 @@ The following is a list of values that can be used in a `permalink` definition i
`:filename`
: the content's filename (without extension)
Additionally, a Go time format string prefixed with `:` may be used.
For time-related values, you can also use the layout string components defined in Go's [time package]. For example:
[time package]: https://pkg.go.dev/time#pkg-constants
{{< code-toggle file="config" copy=false >}}
permalinks:
posts: /:06/:1/:2/:title/
{{< /code-toggle >}}
### Appearance
The appearance of a URL is either ugly or pretty.
Type|Path|URL
:--|:--|:--
ugly|content/about.md|`https://example.org/about.html`
pretty|content/about.md|`https://example.org/about/`
By default, Hugo produces pretty URLs. To generate ugly URLs, change your site configuration:
{{< code-toggle file="config" copy=false >}}
uglyURLs = true
{{< /code-toggle >}}
### Post-processing
Hugo provides two mutually exclusive configuration options to alter URLs _after_ it renders a page.
#### Canonical URLs
{{% note %}}
This is a legacy configuration option, superseded by template functions and markdown render hooks, and will likely be [removed in a future release].
[removed in a future release]: https://github.com/gohugoio/hugo/issues/4733
{{% /note %}}
If enabled, Hugo performs a search and replace _after_ it renders the page. It searches for site-relative URLs (those with a leading slash) associated with `action`, `href`, `src`, `srcset`, and `url` attributes. It then prepends the `baseURL` to create absolute URLs.
```text
<a href="/about"><a href="https://example.org/about/">
<img src="/a.gif"><img src="https://example.org/a.gif">
```
This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, this is a legacy configuration option that will likely be removed in a future release.
To enable:
{{< code-toggle file="config" copy=false >}}
canonifyURLs = true
{{< /code-toggle >}}
#### Relative URLs
{{% note %}}
Do not enable this option unless you are creating a serverless site, navigable via the file system.
{{% /note %}}
If enabled, Hugo performs a search and replace _after_ it renders the page. It searches for site-relative URLs (those with a leading slash) associated with `action`, `href`, `src`, `srcset`, and `url` attributes. It then transforms the URL to be relative to the current page.
For example, when rendering `content/posts/post-1`:
```text
<a href="/about"><a href="../../about">
<img src="/a.gif"><img src="../../a.gif">
```
This is an imperfect, brute force approach that can affect content as well as HTML attributes. As noted above, do not enable this option unless you are creating a serverless site.
To enable:
{{< code-toggle file="config" copy=false >}}
relativeURLs = true
{{< /code-toggle >}}
## Aliases
Aliases can be used to create redirects to your page from other URLs.
Create redirects from old URLs to new URLs with aliases:
Aliases comes in two forms:
- An alias with a leading slash is relative to the `baseURL`
- An alias without a leading slash is relative to the current directory
1. Starting with a `/` meaning they are relative to the `BaseURL`, e.g. `/posts/my-blogpost/`
2. They are relative to the `Page` they're defined in, e.g. `my-blogpost` or even something like `../blog/my-blogpost` (new in Hugo 0.55).
### Examples {#alias-examples}
### Example: Aliases
Change the file name of an existing page, and create an alias from the previous URL to the new URL:
Let's assume you create a new piece of content at `content/posts/my-awesome-blog-post.md`. The content is a revision of your previous post at `content/posts/my-original-url.md`. You can create an `aliases` field in the front matter of your new `my-awesome-blog-post.md` where you can add previous paths. The following examples show how to create this field in TOML and YAML front matter, respectively.
{{< code-toggle file="content/posts/new-file-name.md" copy=false >}}
aliases = ['/posts/previous-file-name']
{{< /code-toggle >}}
#### TOML Front Matter
Each of these directory-relative aliases is equivalent to the site-relative alias above:
{{< code file="content/posts/my-awesome-post.md" copy="false" >}}
+++
aliases = [
"/posts/my-original-url/",
"/2010/01/01/even-earlier-url.html"
]
+++
{{< /code >}}
- `previous-file-name`
- `./previous-file-name`
- `../posts/previous-file-name`
#### YAML Front Matter
You can create more than one alias to the current page:
{{< code file="content/posts/my-awesome-post.md" copy="false" >}}
---
aliases:
- /posts/my-original-url/
- /2010/01/01/even-earlier-url.html
---
{{< /code >}}
{{< code-toggle file="content/posts/new-file-name.md" copy=false >}}
aliases = ['previous-file-name','original-file-name']
{{< /code-toggle >}}
Now when you visit any of the locations specified in aliases---i.e., _assuming the same site domain_---you'll be redirected to the page they are specified on. For example, a visitor to `example.com/posts/my-original-url/` will be immediately redirected to `example.com/posts/my-awesome-post/`.
In a multilingual site, use a directory-relative alias, or include the language prefix with a site-relative alias:
### Example: Aliases in Multilingual
{{< code-toggle file="content/posts/new-file-name.de.md" copy=false >}}
aliases = ['/de/posts/previous-file-name']
{{< /code-toggle >}}
On [multilingual sites][multilingual], each translation of a post can have unique aliases. To use the same alias across multiple languages, prefix it with the language code.
### How Aliases Work
In `/posts/my-new-post.es.md`:
Using the first example above, Hugo generates the following site structure:
```md
---
aliases:
- /es/posts/my-original-post/
---
```text
public/
├── posts/
│ ├── new-file-name/
│ │ └── index.html
│ ├── previous-file-name/
│ │ └── index.html
│ └── index.html
└── index.html
```
From Hugo 0.55 you can also have page-relative aliases, so `/es/posts/my-original-post/` can be simplified to the more portable `my-original-post/`
The alias from the previous URL to the new URL is a client-side redirect:
### How Hugo Aliases Work
When aliases are specified, Hugo creates a directory to match the alias entry. Inside the directory, Hugo creates an `.html` file specifying the canonical URL for the page and the new redirect target.
For example, a content file at `posts/my-intended-url.md` with the following in the front matter:
```yml
---
title: My New post
aliases: [/posts/my-old-url/]
---
```
Assuming a `baseURL` of `example.com`, the contents of the auto-generated alias `.html` found at `https://example.com/posts/my-old-url/` will contain the following:
```html
{{< code file="posts/previous-file-name/index.html" copy=false >}}
<!DOCTYPE html>
<html>
<html lang="en-us">
<head>
<title>https://example.com/posts/my-intended-url</title>
<link rel="canonical" href="https://example.com/posts/my-intended-url"/>
<title>https://example.org/posts/new-file-name/</title>
<link rel="canonical" href="https://example.org/posts/new-file-name/">
<meta name="robots" content="noindex">
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<meta http-equiv="refresh" content="0; url=https://example.com/posts/my-intended-url"/>
<meta charset="utf-8">
<meta http-equiv="refresh" content="0; url=https://example.org/posts/new-file-name/">
</head>
</html>
```
{{< /code >}}
The `http-equiv="refresh"` line is what performs the redirect, in 0 seconds in this case. If an end user of your website goes to `https://example.com/posts/my-old-url`, they will now be automatically redirected to the newer, correct URL. The addition of `<meta name="robots" content="noindex">` lets search engine bots know that they should not index your alias page (`https://example.com/posts/my-old-url/`).
Collectively, the elements in the `head` section:
- Tell search engines that the new URL is canonical
- Tell search engines not to index the previous URL
- Tell the browser to redirect to the new URL
Hugo renders alias files before rendering pages. A new page with the previous file name will overwrite the alias, as expected.
### Customize
You may customize this alias page by creating an `alias.html` template in the
layouts folder of your site (i.e., `layouts/alias.html`). In this case, the data passed to the template is
Create a new template (`layouts/alias.html`) to customize the content of the alias files. The template receives the following context:
`Permalink`
: the link to the page being aliased
`Page`
: the Page data for the page being aliased
### Important Behaviors of Aliases
1. Hugo makes no assumptions about aliases. They also do not change based
on your UglyURLs setting. You need to provide absolute paths to your web root
and the complete filename or directory.
2. Aliases are rendered *before* any content are rendered and therefore will be overwritten by any content with the same location.
## Pretty URLs
Hugo's default behavior is to render your content with "pretty" URLs. No non-standard server-side configuration is required for these pretty URLs to work.
The following demonstrates the concept:
```txt
content/posts/_index.md
=> example.com/posts/
content/posts/post-1.md
=> example.com/posts/post-1/
```
## Ugly URLs
If you would like to have what are often referred to as "ugly URLs" (e.g., example.com/urls.html), set `uglyurls = true` or `uglyurls: true` in your site's `config.toml` or `config.yaml`, respectively. You can also set the `HUGO_UGLYURLS` environment variable to `true` when running `hugo` or `hugo server`.
If you want a specific piece of content to have an exact URL, you can specify this in the [front matter] under the `url` key. The following are examples of the same content directory and what the eventual URL structure will be when Hugo runs with its default behavior.
See [Content Organization][contentorg] for more details on paths.

Here's the same organization run with `hugo --uglyURLs`:
```txt

├── posts
| ├── firstpost.md // <- https://example.com/posts/firstpost.html

└── quote

└── second.md // <- https://example.com/quote/second.html
```
## Canonicalization
By default, all relative URLs encountered in the input are left unmodified, e.g. `/css/foo.css` would stay as `/css/foo.css`. The `canonifyURLs` field in your site `config` has a default value of `false`.
By setting `canonifyURLs` to `true`, all relative URLs would instead be *canonicalized* using `baseURL`. For example, assuming you have `baseURL = https://example.com/`, the relative URL `/css/foo.css` would be turned into the absolute URL `https://example.com/css/foo.css`.
Benefits of canonicalization include fixing all URLs to be absolute, which may aid with some parsing tasks. Note, however, that all modern browsers handle this on the client without issue.
Benefits of non-canonicalization include being able to have scheme-relative resource inclusion; e.g., so that `http` vs `https` can be decided according to how the page was retrieved.
{{% note "`canonifyURLs` default change" %}}
In the May 2014 release of Hugo v0.11, the default value of `canonifyURLs` was switched from `true` to `false`, which we think is the better default and should continue to be the case going forward. Please verify and adjust your website accordingly if you are upgrading from v0.10 or older versions.
{{% /note %}}
To find out the current value of `canonifyURLs` for your website, you may use the handy `hugo config` command added in v0.13.
```txt
hugo config | grep -i canon
```
Or, if you are on Windows and do not have `grep` installed:
```txt
hugo config | FINDSTR /I canon
```
## Set URL in Front Matter
In addition to specifying permalink values in your site configuration for different content sections, Hugo provides even more granular control for individual pieces of content.
Both `slug` and `url` can be defined in individual front matter. For more information on content destinations at build time, see [Content Organization][contentorg].
From Hugo 0.55, you can use URLs relative to the current site context (the language), which makes it simpler to maintain. For a Japanese translation, both of the following examples would get the same URL:
```markdown
---
title: "Custom URL!"
url: "/jp/custom/foo"
---
```
```markdown
---
title: "Custom URL!"
url: "custom/foo"
---
```
## Relative URLs
By default, all relative URLs are left unchanged by Hugo, which can be problematic when you want to make your site browsable from a local file system.
Setting `relativeURLs` to `true` in your [site configuration][config] will cause Hugo to rewrite all relative URLs to be relative to the current content.
For example, if your `/posts/first/` page contains a link to `/about/`, Hugo will rewrite the URL to `../../about/`.

## Create Your Fork
## GitHub workflow
It's best to make changes to the Hugo docs on your local machine to check for consistent visual styling. Make sure you've created a fork of [hugoDocs](https://github.com/gohugoio/hugoDocs) on GitHub and cloned the repository locally on your machine. For more information, you can see [GitHub's documentation on "forking"][ghforking] or follow along with [Hugo's development contribution guide][hugodev].
Step 1
: Fork the [documentation repository].
You can then create a separate branch for your additions. Be sure to choose a descriptive branch name that best fits the type of content. The following is an example of a branch name you might use for adding a new website to the showcase:
Step 2
: Clone your fork.
```txt
git checkout -b jon-doe-showcase-addition
Step 3
: Create a new branch with a descriptive name.
```bash
git checkout -b fix/typos-site-variables
```
## Add New Content
Step 4
: Make changes.
The Hugo docs make heavy use of Hugo's [archetypes] feature. All content sections in Hugo documentation have an assigned archetype.
Step 5
: Commit your changes with a descriptive commit message, typically 50 characters or less. Included the "Closes" keyword if your change addresses one or more open [issues].
Adding new content to the Hugo docs follows the same pattern, regardless of the content section:
```bash
git commit -m "Fix typos on site variables page
```txt
hugo new <DOCS-SECTION>/<new-content-lowercase>.md
Closes #1234
Closes #5678"
```
### Add a New Function
Step 5
: Push the new branch to your fork of the documentation repository.
Once you have cloned the Hugo repository, you can create a new function via the following command. Keep the filename lowercase.
Step 6
: Visit the [documentation repository] and create a pull request (PR).
```txt
hugo new functions/newfunction.md
```
[documentation repository]: https://github.com/gohugoio/hugoDocs/
[issues]: https://github.com/gohugoio/hugoDocs/issues
The archetype for `functions` according to the Hugo docs is as follows:
Step 7
: A project maintainer will review your PR, and may request changes. You may delete your branch after the maintainer merges your PR.
{{< code file="archetypes/functions.md" >}}
{{< readfile file="/archetypes/functions.md">}}
{{< /code >}}
## Including sample code
#### New Function Required Fields
{{% note %}}
Use this syntax to include shortcodes calls within your code samples:
Here is a review of the front matter fields automatically generated for you using `hugo new functions/*`:
`{{</*/* foo */*/>}}`\
`{{%/*/* foo */*/%}}`
{{% /note %}}
***`title`***
: this will be auto-populated in all lowercase when you use `hugo new` generator.
### Fenced code blocks
***`linktitle`***
: the function's actual casing (e.g., `replaceRE` rather than `replacere`).
Include the language when using a fenced code block.
***`description`***
: a brief description used to populate the [Functions Quick Reference](/functions/).
`categories`
: currently auto-populated with 'functions` for future-proofing and portability reasons only; ignore this field.
`tags`
: only if you think it will help end users find other related functions
`signature`
: this is a signature/syntax definition for calling the function (e.g., `apply SEQUENCE FUNCTION [PARAM...]`).
`workson`
: acceptable values include `lists`,`taxonomies`, `terms`, `groups`, and `files`.
`hugoversion`
: the version of Hugo that will ship with this new function.
`relatedfuncs`
: other [templating functions] you feel are related to your new function to help fellow Hugo users.
`{{.Content}}`
: an extended description of the new function; examples are not only welcomed but encouraged.
In the body of your function, expand the short description used in the front matter. Include as many examples as possible, and leverage the Hugo docs [`code` shortcode](#add-code-blocks). If you are unable to add examples but would like to solicit help from the Hugo community, add `needsexample: true` to your front matter.
## Add Code Blocks
Code blocks are crucial for providing examples of Hugo's new features to end users of the Hugo docs. Whenever possible, create examples that you think Hugo users will be able to implement in their own projects.
### Standard Syntax
Across many pages on the Hugo docs, the typical triple-back-tick Markdown syntax (```` ``` ````) is used. If you do not want to take the extra time to implement the following code block shortcodes, please use standard GitHub-flavored Markdown.
````txt
````text
```go-html-template
{{ range site.RegularPages }}
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
{{ if eq $foo "bar" }}
{{ print "foo is bar" }}
{{ end }}
```
````
### Code Block Shortcode
The Hugo documentation comes with a very robust shortcode for adding interactive code blocks.
{{% note %}}
With the `code` shortcodes, *you must include triple back ticks and a language declaration*. This was done by design so that the shortcode wrappers were easily added to legacy documentation and will be that much easier to remove if needed in future versions of the Hugo docs.
{{% /note %}}
### `code`
`code` is the Hugo docs shortcode you'll use most often. `code` requires has only one named parameter: `file`. Here is the pattern:
Rendered:
```go-html-template
{{%/* code file="smart/file/name/with/path.html" download="download.html" copy="true" */%}}
A whole bunch of coding going on up in here!
{{%/* /code */%}}
{{ if eq $foo "bar" }}
{{ print "foo is bar" }}
{{ end }}
```
The following are the arguments passed into `code`:
### The code shortcode
***`file`***
: the only *required* argument. `file` is needed for styling but also plays an important role in helping users create a mental model around Hugo's directory structure. Visually, this will be displayed as text in the top left of the code block.
Use the `code` shortcode to include the file name and a copy-to-clipboard button. This shortcode accepts these optional parameters:
`download`
: if omitted, this will have no effect on the rendered shortcode. When a value is added to `download`, it's used as the filename for a downloadable version of the code block.
copy
: (`bool`) If `true`, displays a copy-to-clipboard button. Default is `true`.
`copy`
: a copy button is added automatically to all `code` shortcodes. If you want to keep the filename and styling of `code` but don't want to encourage readers to copy the code (e.g., a "Do not do" snippet in a tutorial), use `copy="false"`.
file
: (`string`) The file name to display. If you do not provide a `lang` parameter, the file extension determines the code language.
#### Example `code` Input
lang
: (`string`) The code language. Default is `text`.
This example HTML code block tells Hugo users the following:
1. This file *could* live in `layouts/_default`, as demonstrated by `layouts/_default/single.html` as the value for `file`.
2. This snippet is complete enough to be downloaded and implemented in a Hugo project, as demonstrated by `download="single.html"`.
```go-html-template
{{</* code file="layouts/_default/single.html" download="single.html" */>}}
{{ define "main" }}
<main>
<article>
<header>
<h1>{{.Title}}</h1>
{{with .Params.subtitle}}
<span>{{.}}</span>
</header>
<div>
{{.Content}}
</div>
<aside>
{{.TableOfContents}}
</aside>
</article>
</main>
````text
{{</* code file="layouts/_default_/single.html" */>}}
{{ if eq $foo "bar" }}
{{ print "foo is bar" }}
{{ end }}
{{</* /code */>}}
```
##### Example 'code' Display
````
The output of this example will render to the Hugo docs as follows:
Rendered:
{{< code file="layouts/_default/single.html" download="single.html" >}}
{{ define "main" }}
<main>
<article>
<header>
<h1>{{.Title}}</h1>
{{with .Params.subtitle}}
<span>{{.}}</span>
</header>
<div>
{{.Content}}
</div>
<aside>
{{.TableOfContents}}
</aside>
</article>
</main>
{{< code file="layouts/_default_/single.html" >}}
{{ if eq $foo "bar" }}
{{ print "foo is bar" }}
{{ end }}
{{< /code >}}
<!-- #### Output Code Block
### The code-toggle shortcode
The `output` shortcode is almost identical to the `code` shortcode but only takes and requires `file`. The purpose of `output` is to show *rendered* HTML and therefore almost always follows another basic code block *or* and instance of the `code` shortcode:
Use the `code-toggle` shortcode to display examples of site configuration, front matter, or data files. This shortcode accepts these optional parameters:
```
{{%/* output file="posts/my-first-post/index.html" */%}}
<h1>This is my First Hugo Blog Post</h1>
<p>I am excited to be using Hugo.</p>
{{%/* /output */%}}
copy
: (`bool`) If `true`, displays a copy-to-clipboard button. Default is `true`.
file
: (`string`) The file name to display. Omit the file extension for site configuration and data file examples.
fm
: (`bool`) If `true`, displays the code as front matter. Default is `false`.
#### Site configuration example
```text
{{</* code-toggle file="config" */>}}
baseURL = 'https://example.org'
languageCode = 'en-US'
title = "Example Site"
{{</* /code-toggle */>}}
```
The preceding `output` example will render as follows to the Hugo docs:
Rendered:
{{< output file="posts/my-first-post/index.html" >}}
<h1>This is my First Hugo Blog Post</h1>
<p>I am excited to be using Hugo.</p>
{{< /output >}} -->
{{< code-toggle file="config" >}}
baseURL = 'https://example.org'
languageCode = 'en-US'
title = "Example Site"
{{< /code-toggle >}}
## Blockquotes
#### Front matter example
Blockquotes can be added to the Hugo documentation using [typical Markdown blockquote syntax][bqsyntax]:
```md
> Without the threat of punishment, there is no joy in flight.
```text
{{</* code-toggle file="content/about.md" fm=true */>}}
title = "About"
date = 2023-04-02T12:47:24-07:00
draft = false
{{</* /code-toggle */>}}
```
The preceding blockquote will render as follows in the Hugo docs:
Rendered:
> Without the threat of punishment, there is no joy in flight.
However, you can add a quick and easy `<cite>` element (added on the client via JavaScript) by separating your main blockquote and the citation with a hyphen with a single space on each side:
```md
> Without the threat of punishment, there is no joy in flight. - [Kobo Abe](https://en.wikipedia.org/wiki/Kobo_Abe)
```
Which will render as follows in the Hugo docs:
> Without the threat of punishment, there is no joy in flight. - [Kobo Abe][abe]
{{% note "Blockquotes `!=` Admonitions" %}}
Previous versions of Hugo documentation used blockquotes to draw attention to text. This is *not* the [intended semantic use of `<blockquote>`](https://html5doctor.com/cite-and-blockquote-reloaded/). Use blockquotes when quoting. To note or warn your user of specific information, use the admonition shortcodes that follow.
{{% /note %}}
{{< code-toggle file="content/about.md" fm=true >}}
title = "About"
date = 2023-04-02T12:47:24-07:00
draft = false
{{< /code-toggle >}}
## Admonitions
**Admonitions** are common in technical documentation. The most popular is that seen in [reStructuredText Directives][sourceforge]. From the SourceForge documentation:
Use the `note` shortcode to draw attention to content. Use the `{{%/* */%}}` notation when calling this shortcode.
> Admonitions are specially marked "topics" that can appear anywhere an ordinary body element can. They contain arbitrary body elements. Typically, an admonition is rendered as an offset block in a document, sometimes outlined or shaded, with a title matching the admonition type. - [SourceForge][sourceforge]
The Hugo docs contain three admonitions: `note`, `tip`, and `warning`.
### `note` Admonition
Use the `note` shortcode when you want to draw attention to information subtly. `note` is intended to be less of an interruption in content than is `warning`.
#### Example `note` Input
{{< code file="note-with-heading.md" >}}
```text
{{%/* note */%}}
Here is a piece of information I would like to draw your **attention** to.
This is **bold** text.
{{%/* /note */%}}
{{< /code >}}
#### Example `note` Output
{{< output file="note-with-heading.html" >}}
{{% note %}}
Here is a piece of information I would like to draw your **attention** to.
{{% /note %}}
{{< /output >}}
#### Example `note` Display
```
{{% note %}}
Here is a piece of information I would like to draw your **attention** to.
This is **bold** text.
{{% /note %}}
### `tip` Admonition
Use the `tip` shortcode when you want to give the reader advice. `tip`, like `note`, is intended to be less of an interruption in content than is `warning`.
#### Example `tip` Input
{{< code file="using-tip.md" >}}
{{%/* tip */%}}
Here's a bit of advice to improve your productivity with Hugo.
{{%/* /tip */%}}
{{< /code >}}
#### Example `tip` Output
{{< output file="tip-output.html" >}}
{{% tip %}}
Here's a bit of advice to improve your productivity with Hugo.
{{% /tip %}}
{{< /output >}}
#### Example `tip` Display
{{% tip %}}
Here's a bit of advice to improve your productivity with Hugo.
{{% /tip %}}
### `warning` Admonition
Use the `warning` shortcode when you want to draw the user's attention to something important. A good usage example is for articulating breaking changes in Hugo versions, known bugs, or templating "gotchas."
#### Example `warning` Input
{{< code file="warning-admonition-input.md" >}}
{{%/* warning */%}}
This is a warning, which should be reserved for *important* information like breaking changes.
{{%/* /warning */%}}
{{< /code >}}
#### Example `warning` Output
{{< output file="warning-admonition-output.html" >}}
{{% warning %}}
This is a warning, which should be reserved for *important* information like breaking changes.
{{% /warning %}}
{{< /output >}}
#### Example `warning` Display
{{% warning %}}
This is a warning, which should be reserved for *important* information like breaking changes.
{{% /warning %}}

Whenever you use a `cond` function, *both* variable expressions are *always* evaluated. This means that a usage like `cond false (div 1 0) 27` will throw an error because `div 1 0` will be evaluated *even though the condition is false*.
In other words, the `cond` function does *not* provide [short-circuit evaluation](https://en.wikipedia.org/wiki/Short-circuit_evaluation) and does *not* work like a normal [ternary operator](https://en.wikipedia.org/wiki/%3F:) that will pass over the first expression if the condition returns `false`.

Both of the above `default` function calls return `Roboto`.
A `default` value, however, does not need to be hard coded like the previous example. The `default` value can be a variable or pulled directly from the front matter using dot notation:

## findRESubmatch
In Hugo 0.110.0 we added a variant of `findRe` that returns a slice of strings holding the text of the leftmost match of the regular expression in s and the matches, if any, of its subexpressions.
This:
```go-html-template
{{ findRESubmatch §§<a\s*href="(.+?)">(.+?)</a>§§ §§<li><a href="#foo">Foo</a></li> <li><a href="#bar">Bar</a></li>§§ | print | safeHTML }}

Will print:
```
[[<a href=\"#foo\">Foo</a> #foo Foo] [<a href=\"#bar\">Bar</a> #bar Bar]]

```go-html-template
{{ findRESubmatch `a(x*)b` "-ab-" }} → [["ab" ""]]
{{ findRESubmatch `a(x*)b` "-axxb-" }} → [["axxb" "xx"]]
{{ findRESubmatch `a(x*)b` "-ab-axb-" }} → [["ab" ""] ["axb" "x"]]
{{ findRESubmatch `a(x*)b` "-axxb-ab-" }} → [["axxb" "xx"] ["ab" ""]]
{{ findRESubmatch `a(x*)b` "-axxb-ab-" 1 }} → [["axxb" "xx"]]
```
## Practical example
This markdown:
```text
- [Example](https://example.org)
- [Hugo](https://gohugo.io)
```
Produces this HTML:
```html
<ul>
<li><a href="https://example.org">Example</a></li>
<li><a href="https://gohugo.io">Hugo</a></li>
</ul>
```
To match the anchor elements, capturing the link destination and text:
```go-html-template
{{ $regex := `<a\s*href="(.+?)">(.+?)</a>` }}
{{ $matches := findRESubmatch $regex .Content }}
```
Viewed as JSON, the data structure of `$matches` in the code above is:
```json
[
[
"<a href=\"https://example.org\"></a>Example</a>",
"https://example.org",
"Example"
],
[
"<a href=\"https://gohugo.io\">Hugo</a>",
"https://gohugo.io",
"Hugo"
]
]
```
To render the `href` attributes:
```go-html-template
{{ range $matches }}
{{ index . 1 }}
{{ end }}
```
Result:
```text
https://example.org
https://gohugo.io
```

The variable for `.Params.location` is a string and can therefore replace `oslo` in the example above:

{{ (index .Site.Data.locations .Params.location).pop_city }}

Useful for turning strings into numbers.
With a decimal (base 10) input:
```
{{ int "123" }} → 123
```go-html-template
{{ int 11 }} → 11 (int)
{{ int "11" }} → 11 (int)
{{ int 11.1 }} → 11 (int)
{{ int 11.9 }} → 11 (int)
```
{{% note "Usage Note" %}}
If the input string is supposed to represent a decimal number, and if it has
leading 0's, then those 0's will have to be removed before passing the string
to the `int` function, else that string will be tried to be parsed as an octal
number representation.
With a binary (base 2) input:
The [`strings.TrimLeft` function](/functions/strings.trimleft/) can be used for
this purpose.
```
{{ int ("0987" | strings.TrimLeft "0") }}
{{ int ("00987" | strings.TrimLeft "0") }}
```go-html-template
{{ int 0b11 }} → 3 (int)
{{ int "0b11" }} → 3 (int)
```
### Explanation
With an octal (base 8) input (use either notation):
The `int` function eventually calls the `ParseInt` function from the Go library
`strconv`.
```go-html-template
{{ int 011 }} → 9 (int)
{{ int "011" }} → 9 (int)
From its [documentation](https://golang.org/pkg/strconv/#ParseInt):
{{ int 0o11 }} → 9 (int)
{{ int "0o11" }} → 9 (int)
```
> the base is implied by the string's prefix: base 16 for "0x", base 8 for "0",
> and base 10 otherwise.
With a hexadecimal (base 16) input:
```go-html-template
{{ int 0x11 }} → 17 (int)
{{ int "0x11" }} → 17 (int)
```
{{% note %}}
Values with a leading zero are octal (base 8). When casting a string representation of a decimal (base 10) number, remove leading zeros:
`{{ strings.TrimLeft "0" "0011" | int }} → 11`

`len` is a built-in function in Go that returns the length of a variable according to its type. From the Go documentation:
With a string:
> Array: the number of elements in v.
>
> Pointer to array: the number of elements in *v (even if v is nil).
>
> Slice, or map: the number of elements in v; if v is nil, len(v) is zero.
>
> String: the number of bytes in v.
>
> Channel: the number of elements queued (unread) in the channel buffer; if v is nil, len(v) is zero.
```go-html-template
{{ "ab" | len }} → 2
{{ "" | len }} → 0
```
`len` is also considered a [fundamental function for Hugo templating].
With a slice:
## `len` Example 1: Longer Headings
```go-html-template
{{ slice "a" "b" | len }} → 2
{{ slice | len }} → 0
```
You may want to append a class to a heading according to the length of the string therein. The following templating checks to see if the title's length is greater than 80 characters and, if so, adds a `long-title` class to the `<h1>`:
With a map:
{{< code file="check-title-length.html" >}}
<header>
<h1{{if gt (len .Title) 80}} class="long-title"{{end}}>{{.Title}}</h1>
</header>
{{< /code >}}
```go-html-template
{{ dict "a" 1 "b" 2 | len }} → 2
{{ dict | len }} → 0
```
## `len` Example 2: Counting Pages with `where`
With a collection:
The following templating uses [`where`] in conjunction with `len` to
figure out the total number of content pages in a `posts` [section]:
```go-html-template
{{ site.RegularPages | len }} → 42
```
{{< code file="how-many-posts.html" >}}
{{ $posts := (where .Site.RegularPages "Section" "==" "posts") }}
{{ $postCount := len $posts }}
{{< /code >}}
You may also determine the number of pages in a collection with:
Note the use of `.RegularPages`, a [site variable] that counts all regular content pages but not the `_index.md` pages used to add front matter and content to [list templates].
[fundamental function for Hugo templating]: /templates/introduction/
[list templates]: /templates/lists/
[section]: /content-management/sections/
[site variable]: /variables/site/
[`where`]: /functions/where/
```go-html-template
{{ site.RegularPages.Len }} → 42
