`date(format=)`-Filter is not localized

[ibotty]

Zola version: zola-0.10.1-1.fc32.x86_64

Expected Behavior

in config.toml:

default_language = 'de'

{{ "2020-07-27"  | date(format="%B") }}

is not localized: It returns "July" and not "Juli".

I am certainly missing some setting to make it all work.

You're not missing anything, chrono - the underlying date library - is not localized and only supports English :/

@ibotty You can use the translation system to translate your dates.

Personally i only "translate" the order for date numbers:

{%- if page.date -%}<time class="dt-published" datetime="{{ page.date }}">📅&nbsp;{{ page.date | date(format=trans(key="dateFormat", lang=lang)) }}</time>{%- endif -%}

With dateFormat = "%d/%m/%Y" for french and dateFormat = "%m/%d/%Y" for english.

You could apply the same logic to translate month names. You can ask around on the forum if you're stuck and/or contribute documentation when you succeed.

Note: the translation system will undergo some major changes in a future release (#1040) so it's possible you may have to rework it slightly at some point

@southerntofu, thank you for the workaround for date numbers. That's the approach I used. I certainly hope, that it's not decided to need month names before chronotope/chrono#453, the pull request to chrono to add locales, lands and is integrated in zola (if neccessary).

I did use libc-strftime in the meanwhile. It's just strftime directly from the libc

So can something be done in Tera after that PR? I haven't followed/want to read the whole thread.

[cecton]

Ah yes it has been released for some time now. Just add the feature and don't forget to pass the Locale

[ZettaScript]

This issue can be closed now, unless it is about setting automatically the date locale to the website's default language? (which looks difficult and not really necessary)

[Keats]

Let's close it when the version of Zola containing it is released.

[sardemff7]

It seems that the expected locale parameters of Tera’s date filter takes a full locale specifier (e.g. fr_FR), so you cannot pass it lang directly. Would that make sense for Zola to directly provide a locale variable somehow?

[Keats]

It's kinda odd to have an automatic lang -> locale conversion but maybe it does not matter for dates? Anyone has some links on that?
