Excluding Weeknotes From Main Page

I just went to write up a new weeknotes post, and noticed that that would have meant that all three previewed posts on my main page would have been weeknotes. That simply will not do! So into the depths of Hugo layouts I ventured once more.

The relevant part of the original layout looks like¹ this:

...
{{ $section := where $.Site.RegularPages "Section" "in" $section_name }}
{{ $section_count := len $section }}
{{ if ge $section_count 1 }}
  <div class="pa3 pa4-ns w-100 w-70-ns center">
    {{/* Use $section_name to get the section title. Use "with" to only show it if it exists */}}
    {{ with $.Site.GetPage "section" $section_name }}
        <h1 class="flex-none">
          {{ $.Param "recent_copy" | default (i18n "recentTitle" .) }}
        </h1>
      {{ end }}

    {{ $n_posts := $.Param "recent_posts_number" | default 3 }}

    <section class="w-100 mw8">
      {{/* Range through the first $n_posts items of the section */}}
      {{ range (first $n_posts $section) }}
        <div class="relative w-100 mb4">
          {{ .Render "summary-with-image" }}
        </div>
      {{ end }}
    </section>
...

Although the where function does have a pretty good selection of operators, there’s no not or not intersection - so, although it’s possible to filter to all members which have a particular slice-term contained in some other slice, it’s not immediately possible to find all members that don’t have a given value in a slice-term. Thankfully, later in the same docs there’s a link to collections/complement, which does exactly what I want. The final result² was:

...
{{ $section_original := where $.Site.RegularPages "Section" "in" $section_name }}
{{ $weeknotes := where $section_original "Params.tags" "intersect" (slice "Weeknotes") }}
{{ $section := complement $weeknotes $section_original }}
...

Since I don’t want those weeknotes to be undiscoverable, though, I also added a dedicated section for them on the homepage. Pretty happy with how that turned out!
