Is there a way to set frontmatter property for every list in the project?

[MikiVanousek]

I want to have my posts separated into several categories, each post belonging to one and only one category. I reconned the best way to do this is to create subfolders and list in each sub folder.

So far I made only one category foss. This is my content folder structure:

content
├── horolux
│   ├── horolux-scs.png
│   ├── index.md
│   └── wake-up.jpeg
├── _index.md
└── posts
    ├── foss
    │   ├── _index.md
    │   └── root-arrow.md
    └── _index.md

This means, that when I open the posts list, I see a list of category lists. Each category is a list of posts.

I want each post to display the date it was made and updated.

But, if the list item is not a blog post, but a category, I want the dates to be hidden.

I now set this in the category front matter.

---
showDate: false
showDateUpdated: false
title: "Free And Open Source Software"
description: "Everything I wrote about open source"
summary: "Everything I wrote about open source"
---

But this means I need to set it for each new category (and potentially subcategory in the future) I create. I tried setting these in the [list] config, but it did not take effect. Is there a way to change this globally? If you are not a post, but a list, do not show your date!

Thanks for the question. I may not be fully understanding your end objective here but a useful feature of Hugo that may help is the special cascade front matter parameter. When set, any children of this page will inherit the parameters that are cascaded.

You can essentially do something like this in your _index.md front matter to hide the dates on any sub-pages automatically:

---
title: "Categories"
cascade:
  showDate: false
  showDateUpdated: false
---

The example site in the theme uses this method in content/samples/_index.md if you want to see a working example.

Is there a way to apply one set of values to all the articles and another to all the lists? I tried:

---
cascade:
- target:
    kind: article
  showDate: true
  showDateUpdated: true
- target:
  kind: list
  showDate: false
  showDateUpdated: false
---

But this applies the first set of values to all sub-files.
