10 years ago Here it is with comments, I will get around to making it a full recipe soon with a lot more detail, but hopefully this is enough to get you going.
//- Create an empty array of the articles
articles = []
//- Iterate over the articles like you would normally
for article, slug in public.articles._data
//- Assign the slug, which is the object key, to a value instead
- article.slug = slug
//- Push each article into the empty array
- articles.push(public.articles._data[slug])
//- Iterate over the articles array
each article, i in articles
//- Article slug is the old object key that matched the file name,
//- Like "a-post" for example
//- Match it against the current page
if article.slug == current.source
//- Previous is one before this array item
//- Next is one after
//- Variables make it easy to template
- prev = articles[i - 1]
- next = articles[i + 1]
//- The actual links
ul
if prev
a(href="#{ prev.slug }") ← #{ prev.title }
if next
a(href="#{ next.slug }") #{ next.title } →Here is the _data.json file I’m using, in articles/_data.json:
{
"welcome-to-harp": {
"title": "Welcome to Harp"
},
"go-out-and-make-it-your-own": {
"title": "Go Out & Make It Your Own"
},
"a-post": {
"title": "An example post"
}
}

I'm looking for a way to link to the 'next' and 'previous' objects in a JSON file.
On IRC kennethormandy requested I log this as he has a recipe for it.
