Page resources are available for [page bundles]({{< relref "/content-management/page-bundles" >}}) only, i.e. a directory with either a index.md, or _index.md file at its root. Resources are only attached to the lowest page they are bundled with, and simple which names does not contain index.md are not attached any resource.

Properties

ResourceType

The main type of the resource. For example, a file of MIME type image/jpeg has the ResourceType image.

Name

Default value is the filename (relative to the owning page). Can be set in front matter.

Title

Default value is the same as .Name. Can be set in front matter.

Permalink

The absolute URL to the resource. Resources of type page will have no value.

RelPermalink

The relative URL to the resource. Resources of type page will have no value.

Content

The content of the resource itself. For most resources, this returns a string with the contents of the file. This can be used to inline some resources, such as <script>{{ (.Resources.GetMatch "myscript.js").Content | safeJS }}</script> or <img src="{{ (.Resources.GetMatch "mylogo.png").Content | base64Encode }}">.

MediaType

The MIME type of the resource, such as image/jpeg.

MediaType.MainType

The main type of the resource's MIME type. For example, a file of MIME type application/pdf has for MainType application.

MediaType.SubType

Methods

ByType

{{ .Resources.Match "images/*" }}

GetMatch

Same as Match but will return the first match.

Pattern Matching

.Resources.Match "**/sunset.jpg" ✅
.Resources.Match "images/*.jpg" ✅
.Resources.Match "**.jpg" ✅
.Resources.Match "*" 🚫
.Resources.Match "sunset.jpg" 🚫
.Resources.Match "*sunset.jpg" 🚫

Page Resources Metadata

The page resources' metadata is managed from the corresponding page's front matter with an array/table parameter named resources. You can batch assign values using wildcards.

{{% note %}} Resources of type page get Title etc. from their own front matter. {{% /note %}}

name

Sets the value returned in Name.

{{% warning %}} The methods Match and GetMatch use Name to match the resources. {{%/ warning %}}

title

Sets the value returned in Title

params

A map of custom key/values.

Resources metadata example

{{< code-toggle copy="false">}} title: Application date : 2018-01-25 resources :

• src : "images/sunset.jpg" name : "header"
• src : "documents/photo_specs.pdf" title : "Photo Specifications" params: icon : "photo"
• src : "documents/guide.pdf" title : "Instruction Guide"
• src : "documents/checklist.pdf" title : "Document Checklist"
• src : "documents/payment.docx" title : "Proof of Payment"
• src : "**.pdf" name : "pdf-file-:counter" params : icon : "pdf"
• src : "**.docx" params : icon : "word" {{</ code-toggle >}}

From the example above:

• sunset.jpg will receive a new Name and can now be found with .GetMatch "header".
• documents/photo_specs.pdf will get the photo icon.
• documents/checklist.pdf, documents/guide.pdf and documents/payment.docx will get Title as set by title.
• Every PDF in the bundle except documents/photo_specs.pdf will get the pdf icon.
• All PDF files will get a new Name. The name parameter contains a special placeholder :counter, so the Name will be pdf-file-1, pdf-file-2, pdf-file-3.
• Every docx in the bundle will receive the word icon.

{{% warning %}} The order matters --- Only the first set values of the title, name and params-keys will be used. Consecutive parameters will be set only for the ones not already set. In the above example, .Params.icon is first set to "photo" in src = "documents/photo_specs.pdf". So that would not get overridden to "pdf" by the later set src = "**.pdf" rule. {{%/ warning %}}

The :counter placeholder in name and title

The :counter is a special placeholder recognized in name and title parameters resources.

The counter starts at 1 the first time they are used in either name or title.

For example, if a bundle has the resources photo_specs.pdf, other_specs.pdf, guide.pdf and checklist.pdf, and the front matter has specified the resources as:

{{< code-toggle copy="false">}} resources src = "*specs.pdf" title = "Specification #:counter" resources src = "**.pdf" name = "pdf-file-:counter" {{</ code-toggle >}}

the Name and Title will be assigned to the resource files as follows:

Resource file	Name	Title
checklist.pdf	"pdf-file-1.pdf	"checklist.pdf"
guide.pdf	"pdf-file-2.pdf	"guide.pdf"
other_specs.pdf	"pdf-file-3.pdf	"Specification #1"
photo_specs.pdf	"pdf-file-4.pdf	"Specification #2"
