The elements supported are strings, integers, and floats (only float64).
A useful example of intersect functionality is a "related posts" block. isset allows us to create a list of links to other posts that have tags that intersect with the tags in the current post.
The following is an example of a "related posts" partial template that could be added to a single page template:
{{< code file="layouts/partials/related-posts.html" download="related-posts.html" >}}
-
{{ $page_link := .Permalink }}
{{ $tags := .Params.tags }}
{{ range .Site.Pages }}
{{ $page := . }}
{{ $has_common_tags := intersect $tags .Params.tags | len | lt 0 }}
{{ if and $has_common_tags (ne $page_link $page.Permalink) }}
- {{ $page.Title }} {{ end }} {{ end }}
This is also very useful to use as AND filters when combined with where:
{{ $pages := where .Site.RegularPages "Type" "not in" (slice "page" "about") }}
{{ $pages := $pages | union (where .Site.RegularPages "Params.pinned" true) }}
{{ $pages := $pages | intersect (where .Site.RegularPages "Params.images" "!=" nil) }}
The above fetches regular pages not of page or about type unless they are pinned. And finally, we exclude all pages with no images set in Page params.
See union for OR.
