This include allows to translate the days and months in the date by using strings in _data/locales/[lang].yml

This include can be called with three parameters:

- include.date: the date to be processed

- include.format: the date format. (If empty a default format will be used)

- include.lang: lang to use for translation.

{% endcomment %}

{% comment %}

If the parameter date format is empty the default format set in _config.yml is used.

If there is no default in _config, "%b %-d, %Y" is used.

{% endcomment %}

{% assign date_format_to_be_translated = include.format | default: site.date_format | default: "%b %-d, %Y" %}

{% comment %}

Init to have the indice of the day in the week (num_day) and the indice of the month in the year (num_mont)

Init the lang parameter depending if it's set in the include call, in the page or in the site settings

{% endcomment %}

{% assign num_day = include.date | date: "%w" | plus: 0 %}

{% assign num_month = include.date | date: "%-m" | plus: -1 %}

{% assign lang = include.lang | default: page.lang | default: site.lang %}

Use translated abbreviated weekday if "%a" is used in the format and the translation is available in _data/locales/[lang].yml

{% endcomment %}

{% if site.data.locales[lang].abbreviated_weekday[num_day] %}

{% assign date_format_to_be_translated = date_format_to_be_translated | replace: "%a", site.data.locales[lang].abbreviated_weekday[num_day] %}

{% endif %}

{% comment %}

Use translated full weekday if "%A" is used in the format and the translation is available in _data/locales/[lang].yml

{% endcomment %}

{% if site.data.locales[lang].full_weekday[num_day] %}

{% assign date_format_to_be_translated = date_format_to_be_translated | replace: "%A", site.data.locales[lang].full_weekday[num_day] %}

{% endif %}

{% comment %}

Use translated abbreviated month if "%b" is used in the format and the translation is available in _data/locales/[lang].yml
