How to share params among translations of same post?

johnson · July 31, 2019, 2:36am

I have a site with 4 languages.
I create a page bundle for each post, where I create an index.lang.md for each language.

How could I share some post params (like categories, featured-images etc)
so that I do not have to type the same 4 times?

Is it possible to put the only at default language or a common file?

Thanks

I see no answers at all.

Is this possible or do I have to ask it a wanted feature?

It’s not possible right now without help of an external script.

I am already doing something like what you want using Emacs and Org mode, but Hugo doesn’t natively support that.

Though, the good news are that this feature is already being discussed:

Enhancement Outdated

This issue adresses batch assignment of Front Matter values to descendants of an…y given content file and is inspired to some extend by the data assignment logic of https://github.com/11ty/eleventy. Batch assign is already addressed here [https://github.com/gohugoio/hugo/issues/5455](https://github.com/gohugoio/hugo/issues/5455) but from a single entry point. I think the following could complement the above for many use cases and provide a simpler approach to batch assign. Here, we would simply create a new reserved key in Front Matter underneath which any number of key/value pair could be cascaded through the page’s descendants. Consider the following structure and content files' Front Matter: ```css ├── _index.md ├── blog │ ├── _index.md │ ├── san-fransisco-series │ │ ├── _index.md │ │ ├── castro.md │ │ ├── lombard.md │ │ └── presidio.md │ └── moving-again.md └── contact.md ``` ```yaml # content/_index.md title: Home cascade: banner: images/windows-bliss.jpg ``` ```yaml # content/blog/_index.md title: Blog cascade: banner: images/typewriter.jpg ``` ```yaml # content/blog/san-fransisco-series/_index.md title: San Fransisco cascade: banner: images/golden-gate-sunset.jpg ``` ```yaml # content/blog/san-fransisco-series/lombard.md title: San Fransisco banner: images/herbie-lombard.jpg ``` Looking at the different content files above, and from within the template files, `.Params.banner` would output the following: | Content file | .Params.banner | cascading from |-----------------------------------|----------------------| ------ | | `/contact.md` | `windows-bliss.jpg` | Homepage | `/blog/moving-again.md` | `typewriter.jpg` | Blog | `/blog/san-fransisco-series/presidio.md` | `golden-gate-sunset` | SF Series | `/blog/san-fransisco-series/castro.md` | `golden-gate-sunset` | SF series | `/blog/san-fransisco-series/lombard.md` | `herbie-lombard.jpg` | self ### Repercusions They're safe as those "special" key/value pair would be stored in a reserved map. On the other hand this could take care of [https://github.com/gohugoio/hugo/issues/5652](https://github.com/gohugoio/hugo/issues/5652) and potentially other issues not yet identified. ### How to overwrite with an empty value? What if a page does not want a banner? ```yaml # /blog/rip-dear-celebrity title: Rest In Peace dear celebrity banner: false ``` It becomes the user responsibility to allow an empty or boolean overwrite to editors. I think it's a fair trade-off. ### Data source This for now does not solve the problem of batch assigning Front Matter to remote content, but it could if the user can create a content file matching the remote’s content section and store the section’s Front Matter (cascading or not) in there.

You are right. I see that @bep has included if as 0.57 milestone!
Hope to see it soon implemented!

On the meantime could you elaborate on how to manage this with an external script?
Thanks

I haven’t tried it, but check out Hugo metadata utility.
