Support setting "resources" in front-matter

[Kaushal Modi]

This feature is upcoming in Hugo v0.33 (gohugoio/hugo@20c9b6e).

Example front-matter:

+++
date = 2017-01-17
title = "My Bundle With TOML Resource Metadata"
layout = "bundle-resource-meta"

[[resources]]
# The order matters
src = "image-4.png"
title = "TOML: The Fourth Image"
[[resources]]
src = "*.png"
name = "my-cool-image-:counter"
title = "TOML: The Image #:counter"
[resources.params]
byline = "bep"
+++

---
date: 2017-01-17
title: My Bundle With YAML Resource Metadata
layout: bundle-resource-meta
resources:
# The order matters
- src: "image-4.png"
  title: "The Fourth Image"
- src: "*.png"
  name: "my-cool-image-:counter"
  title: "The Image #:counter"
  params:
    byline: "bep"
---

---
title: "Bundle Galore"
slug: pageslug
date: 2017-10-09
resources:
- src: "*.jpg"
  name: "my-sunset-:counter"
  title: "Sunset Galore :counter"
  params:
    myParam: "My Sunny Param"

Possible Org properties drawer syntax that would translate to:

[[resources]]
# The order matters
src = "image-4.png"
title = "TOML: The Fourth Image"
[[resources]]
src = "*.png"
name = "my-cool-image-:counter"
title = "TOML: The Image #:counter"
[resources.params]
byline = "bep"

Org

:PROPERTIES:
:EXPORT_HUGO_RESOURCES: :src "image-4.png" :title "TOML: The Fourth Image"
:EXPORT_HUGO_RESOURCES: :src "*.png" :name "my-cool-image-:counter" :title "TOML: The Image #:counter"
:EXPORT_HUGO_RESOURCES_PARAMS: :src "*.png" :byline "bep"
:END:

Somehow ensure that the order of the :src in :EXPORT_HUGO_RESOURCES: is retained.

Note

• Specifying :src is mandatory.. throw user-error in its absence.

[Kaushal Modi]

There's a better way in Org:

:PROPERTIES:
:EXPORT_HUGO_RESOURCES: :src "image-4.png" :title "TOML: The Fourth Image"
:EXPORT_HUGO_RESOURCES+: :src "*.png" :name "my-cool-image-:counter" :title "TOML: The Image #:counter"
:EXPORT_HUGO_RESOURCES+: :src "*.png" :byline "bep"
:END:

Parameters that are not src, name or title will be automatically put in params.
