Next/previous collection with permalink: false

[h0r0m4n]

The items in the collection that contains permalink: false is still considered to be a next or previous post during 11ty rendering.

To Reproduce
Posts structure:

posts/post-a.md
posts/post-b.md -> permalink: false
posts/post-c.md

Prev/Next:

<ul>
    {% set previousPost = collections.posts | getPreviousCollectionItem(page) %}
    {% if previousPost %}<li><a href="{{ previousPost.url }}">{{ previousPost.data.title }}</a></li>{% endif %}

    {% set nextPost = collections.posts | getNextCollectionItem(page) %}
    {% if nextPost %}<li><a href="{{ nextPost.url }}">{{ nextPost.data.title }}</a></li>{% endif %}
</ul>

Expected behaviour
When I open http://localhost:8080/posts/post-a/ the URL of the next post is http://localhost:8080/posts/post-b/false instead of http://localhost:8080/posts/post-c/

Environment

• Eleventy: v0.11.1
• NodeJS: v14.15.0
• OS: Big Sur 11.0.1

@h0r0m4n not an ideal solution, but I use a filter to filter out items with permalink: false

The syntax would be approximately:
{% set thePosts = collections.posts | permalinkNotFalse | getPreviousCollectionItem(page) %}

My filter for this:

exports.permalinkNotFalse = (items) => {
	return items.filter( item => {
		return (item.data.permalink !== false)
	})
}
