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 }}">.

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

name

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

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. For example, in the above example, .Params.icon is already 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"
