Hakyll.Web.Meta.OpenGraph

Description

Open Graph metadata, as described at https://ogp.me/. This implementation supports the following properties:

`og:type`	Hardcoded value `"article"`
`og:url`	Required concatenation of `root` and `url` context fields, both of which are required.
`og:title`	Required title of article, from `title` field.
`og:description`	Optional brief description taken from context field `og-description`, if set.
`og:image`	Optional image URL taken from context field `og-image`, if set.

To use, add openGraphField to the template context:

let
  context = defaultContext <> …
  postContext = context <> openGraphField "opengraph" context

and update the template:

<head>
  <title>$title$/title
  <link rel="stylesheet" type="text/css" href="/css/default.css" />
  $if(opengraph)$$opengraph$$endif$
</head>
