Sort by lastmod

unique · February 15, 2023, 4:23pm

Hello everyone,
I would like to sort by lastmod instead of published time.
Is it possible?

I’m using the no longer maintained story theme of Mr Schwartz

Yes, this example is shown in the Lists of Content documentation.

Below you’ll see the .Pages.ByLastmod declaration.

<ul>
    <!-- orders content according to the "lastmod" field in front matter -->
    {{ range .Pages.ByLastmod }}
        <li>
            <h1><a href="{{ .Permalink }}">{{ .Title }}</a></h1>
            <time>{{ .Date.Format "Mon, Jan 2, 2006" }}</time>
        </li>
    {{ end }}
</ul>

Thank you,
I guess that at the story theme the code should be placed at the layouts/partials/li.html.
But how can I combine it with the already present configuration?
Whatever I’ve tried hasn’t applied to the ordering or has broken the design or ended up with a hugo syntax error.

The theme seems to be somehow complicated with all these added features
I can’t change that. It was the best solution when I needed a starting point.

At the moment there is:

<h1 class="f3 fw1 mt0 lh-title"><a href="{{ .Permalink }}" class="color-inherit dim link">
{{- if eq .Section "talks" }}{{ .Params.event }}: {{ end -}}
{{- cond (eq .Site.Params.titlecase true) (.Title | title | markdownify) (.Title | markdownify) -}}
</a></h1>

See here the full li.html

{{- $hdr := cond (or (in .Site.Params.classes "feature-nohdr") (in .Params.classes "feature-nohdr")) false true -}}

<div class="w-100">

Hmm, Nothing I tried worked.
Do I need to enter the lastmod date for every post manually?
The lastmod is displayed correctly, just the ordering doesn’t work.

I’m not using github. Is there nevertheless any about it to add to config.toml?

Would it help if I upload my site to github?

jmooring · February 16, 2023, 5:53pm

Yes. Otherwise we’re both just guessing.

unique · February 16, 2023, 6:02pm

Do I upload the whole folder?
With all content and all personal data like imprint, GDPR etc?

jmooring · February 16, 2023, 6:03pm

Sorry, you need to learn about Git and GitHub on your own. This is the wrong forum for that.

here it is:

jmooring · February 16, 2023, 6:11pm

This is an incomplete site that doesn’t build.

unique · February 16, 2023, 6:20pm

give me some minutes

unique · February 16, 2023, 6:32pm

You can build it now. I downloaded it and it works with “hugo server”

jmooring · February 16, 2023, 7:08pm

config.toml

lastmod = ["lastmod", ":fileModTime", ":default"]

Because your content does not contain lastmod in front matter, it is falling back to the file system’s last modification time. When you look at your files in a file listing, are the modification dates what you expect?

Unfortunately ordering by modified file date hasn’t worked so far.
This would be the base case for me.
On top the possibility to be able to hardcode the lastmod in frontmatter would be perfect.
I’m going to try out your snippets.

unique · February 17, 2023, 8:16am

It works like a charm

It is ordering by file date but also with higher priority if I manually set lastmod in frontmatter!

Thank you very much !!
