One feed with excluded sections

hendry · July 13, 2020, 6:00am

Hi, I have a current structure like:

[hendry@t480s foobar]$ cat config.yaml
baseURL: https://example.com
title: Example
disableKinds:
    - taxonomy
    - taxonomyTerm
    - sitemap
[hendry@t480s foobar]$ tree content/
content/
├── 2019
│   └── old.md
├── 2020
│   └── fresh.md
└── private-ish
    └── internal-but-public.md

3 directories, 3 files
[hendry@t480s foobar]$ tree public/
public/
├── 2019
│   └── index.xml
├── 2020
│   └── index.xml
├── index.xml
└── private-ish
    └── index.xml

3 directories, 4 files

First I don’t want RSS feeds in the sections like 2019/index.xml 2020/index.xml, I just want one top level /index.xml … how do I achieve that please?

Next I just want only sections to be included except “private-ish” in my feed.

I tried customizing my layout like so:

[hendry@t480s foobar]$ vim public/index.xml
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
  <channel>
    <title>{{ if eq  .Title  .Site.Title }}{{ .Site.Title }}{{ else }}{{ with .Title }}{{.}} on {{ end }}{{ .Site.Title }}{{ end }}</title>
    <link>{{ .Permalink }}</link>
    <lastBuildDate>{{ .Date.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</lastBuildDate>
    {{ with .OutputFormats.Get "RSS" }}
    {{ printf "<atom:link href=%q rel=\"self\" type=%q />" .Permalink .MediaType | safeHTML }}
    {{ end }}
  {{ range .Data.Pages -}}
  {{- if or (ne .Section "private-ish") }}
    <item>le>{{ .Title }}</title>
      <link>{{ .Permalink }}</link>
      <pubDate>{{ .Lastmod.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</pubDate>
      <guid>{{ .Permalink }}</guid>
      <description>{{ .Summary | html }}</description>
    </item>
    {{ end }}
    {{ end }}
  </channel>
</rss>

But that bizaarely only shows indexes and not not the pages!?

[hendry@t480s foobar]$ cat public/index.xml
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
  <channel>
    <title>Example</title>
    <link>https://example.com/</link>
    <lastBuildDate>Mon, 13 Jul 2020 13:34:38 +0800</lastBuildDate>

    <atom:link href="https://example.com/index.xml" rel="self" type="application/rss+xml" />


    <item>
      <title>2020s</title>
      <link>https://example.com/2020/</link>
      <pubDate>Mon, 13 Jul 2020 13:34:38 +0800</pubDate>
      <guid>https://example.com/2020/</guid>
      <description></description>
    </item>


    <item>
      <title>2019s</title>
      <link>https://example.com/2019/</link>
      <pubDate>Mon, 13 Jul 2020 13:33:50 +0800</pubDate>
      <guid>https://example.com/2019/</guid>
      <description></description>
    </item>



  </channel>
</rss>

What am I missing please? Sorry I am trying to simplify https://github.com/gohugoio/hugo/blob/master/tpl/tplimpl/embedded/templates/_default/rss.xml since I found the first few lines too hard to fathom.

Thank you in advance!

config.toml:

[outputs]
home = ["HTML", "RSS"]
page = ["HTML"]
section = ["HTML"]
taxonomy = ["HTML"]
term = ["HTML"]

This is not a good reason to delete code. You are creating problems, not solving them.

This can be simplified to:

{{ if ne .Section "private-ish" }}

This is the default RSS template, with a conditional to exclude the “private-ish” section.

layouts/_default/rss.xml:

{{- $pctx := . -}}
{{- if .IsHome -}}{{ $pctx = .Site }}{{- end -}}
{{- $pages := slice -}}
{{- if or $.IsHome $.IsSection -}}
{{- $pages = $pctx.RegularPages -}}
{{- else -}}
{{- $pages = $pctx.Pages -}}
{{- end -}}
{{- $limit := .Site.Config.Services.RSS.Limit -}}
{{- if ge $limit 1 -}}
{{- $pages = $pages | first $limit -}}
{{- end -}}
{{- printf "<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\"?>" | safeHTML }}
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">
  <channel>
    <title>{{ if eq  .Title  .Site.Title }}{{ .Site.Title }}{{ else }}{{ with .Title }}{{.}} on {{ end }}{{ .Site.Title }}{{ end }}</title>
    <link>{{ .Permalink }}</link>

    <copyright>{{.}}</copyright>{{end}}{{ if not .Date.IsZero }}
    <lastBuildDate>{{ .Date.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</lastBuildDate>{{ end }}
    {{ with .OutputFormats.Get "RSS" }}
	{{ printf "<atom:link href=%q rel=\"self\" type=%q />" .Permalink .MediaType | safeHTML }}
    {{ end }}
    {{ range $pages }}
      {{ if ne .Section "private-ish" }}
      <item>
        <title>{{ .Title }}</title>
        <link>{{ .Permalink }}</link>
        <pubDate>{{ .Date.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</pubDate>

      {{ end }}
    {{ end }}

</rss>

Thank you! Would still love to know why range .Data.Pages didn’t work to iterate through my content.

I delete code to better illustrate the problem and hopefully help me better understand hugo templates.

jmooring · July 14, 2020, 12:21am

.Pages

Collection of regular pages and only first-level section pages under the current list page.

See https://gohugo.io/variables/site/#site-pages

I use enableGitInfo: true since I don’t feel the need to set a Date frontmatter in my posts. That means I need IIUC:

<pubDate>{{ .Lastmod.Format "Mon, 02 Jan 2006 15:04:05 -0700" | safeHTML }}</pubDate>

Next issue is that the last post doesn’t appear at the top. Aka the posts are not ordered by date.

Perhaps I should just give up on using enableGitInfo and resort to front matter instead?

Furthermore I need to exclude several sections and I’m struggling to figure out how to do that.

[hendry@t480s foobar]$ rm -rf public/
[hendry@t480s foobar]$ grep exclude layouts/_default/rss.xml
      {{ if and (ne .Section "private-ish") (ne .Section "2020") (ne .Section "exclude-me-too")  }}

Don’t mess with the date in the template. Instead, add this to config.toml:

[frontmatter]
date = ["lastmod", "date", "publishDate"]

See https://gohugo.io/getting-started/configuration/#configure-dates.

Your “exclude” code looks fine:

{{ if and (ne .Section "private-ish") (ne .Section "2020") (ne .Section "exclude-me-too")  }}

It will exclude those sections from being listed, but it will not prevent them from being built.

hendry · July 14, 2020, 3:41am

My exclude code doesn’t work since it appears in my

[hendry@t480s foobar]$ grep exclude public/index.xml
        <link>https://example.com/exclude-me-too/</link>
        <guid>https://example.com/exclude-me-too/</guid>

Thank you for the frontmatter date trick. That was driving me NUTS! enableGitInfo should ideally imply that.

jmooring · July 14, 2020, 3:49am

Please repost the current version of your RSS template.

hendry · July 14, 2020, 5:42am

Here’s the test site files which includes the template: https://s.natalian.org/2020-07-14/exclude-me-too.zip

jmooring · July 14, 2020, 11:18am

Thank you for sharing your code. This makes issue resolution much more efficient, and others are more likely to offer assistance when you do so.

The “exclude-me-too” directory is not a section. It contains “index.md”, which makes it a page.

Insert {{ .Section }} into your RSS template to troubleshoot.

If you want to exclude by directory name, you can do this:

{{ if and (ne .Section "private-ish") (ne .Section "2020") (not (strings.HasPrefix .File.Dir "exclude-me-too")) }}

hendry · July 15, 2020, 2:17am

Thank you again!

My next thought is that can i match all the section with \d\d\d\d yyyy structure?
