## Properties
|
|
|
|
ResourceType
|
|
: The main type of the resource. For example, a file of MIME type `image/jpg` has for ResourceType `image`.
|
|
|
|
Name
|
|
: Default value is the filename (relative to the owning page). Can be set in front matter.
|
|
|
|
Title
|
|
: Default blank. 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.
|
|
|
|
## Methods
|
|
ByType
|
|
: Returns the page resources of the given type.
|
|
|
|
```go
|
|
{{ .Resources.ByType "image" }}
|
|
```
|
|
Match
|
|
: Returns all the page resources (as a slice) whose `Name` matches the given Glob pattern ([examples](https://github.com/gobwas/glob/blob/master/readme.md)). The matching is case-insensitive.
|
|
|
|
```go
|
|
{{ .Resources.Match "images/*" }}
|
|
```
|
|
|
|
GetMatch
|
|
: Same as `Match` but will return the first match.
|
|
|
|
### Pattern Matching
|
|
```go
|
|
// Using Match/GetMatch to find this images/sunset.jpg ?
|
|
.Resources.Match "images/sun*" ✅
|
|
.Resources.Match "**/Sunset.jpg" ✅
|
|
.Resources.Match "images/*.jpg" ✅
|
|
.Resources.Match "**.jpg" ✅
|
|
.Resources.Match "*" 🚫
|
|
.Resources.Match "sunset.jpg" 🚫
|
|
.Resources.Match "*sunset.jpg" 🚫
|
|
|
|
```
|
|
|
|
## Page Resources Metadata
|
|
|
|
Page Resources' metadata is managed from their page's front matter with an array/table parameter named `resources`. You can batch assign values using a [wildcards](http://tldp.org/LDP/GNU-Linux-Tools-Summary/html/x11655.htm).
|
|
|
|
{{% 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`](#the-counter-placeholder-in-name-and-title), 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.

### 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"` |
|
