Month Abbreviations improvement

[eslepova]

Hi,

We moved from moment to dayjs a few months ago. And everything is perfect except for one thing: declension of months.

In moment we have:
moment.updateLocale('en', { monthsShort : { format: 'янв_фев_мар_апр_мая_июня_июля_авг_сен_окт_ноя_дек'.split('_'), standalone: 'янв_фев_март_апр_май_июнь_июль_авг_сен_окт_ноя_дек'.split('_') } }); (https://momentjs.com/docs/#/customization/month-abbreviations/)

Do you have plans to add it?

[iamkun]

Of course.

Just check UpdateLocale plugin here https://day.js.org/docs/en/customization/customization

[eslepova]

Do you mean you will add it sometime?

[iamkun]

@eslepova we support this . updateLocale already. Just check our website for more detail.

[eslepova]

Yes, but it allows us to add only one monthsShort setting, but moment has 2 settings for monthsShort - format and standalone.
Some languages like Russian have different ways of spelling short months depends of declension. Like "май" and "мая". Both of them are monthsShort.

dayjs('2020-05-25').format('MMM') should return 'май'
dayjs('2020-05-25').format('D MMM') should return '25 мая', but it returns '25 май'

You can check here as a reference. https://github.com/iamkun/dayjs/blob/dev/src/locale/ru.js#L39

monthsShort also accepts a function

Besides, tested dayjs gives the correct result as you mentioned above.

So ru.js already has everything inside it, and I don't have to add 'monthsShort' manually, which it is used to be in the project. Now I understand, thanks a lot!
The reason for the problem was that monthsShort was overwritten in the project.

It would be nice if you put in doc https://day.js.org/docs/en/customization/customization example that monthsShort can be a function.

Thanks a lot again!

doc updated thanks.
