Description

Problem with plural forms of dates on russian translation:

• Обновлено 2 дней назад must be "2 дня"

Same:

• 1 день
• 2,3,4 дня
• 5-20 дней
• 21 день
• 22, 23, 24 дня
• 25 дней

i.e. correct code (PHP, sorry):

return
            ($number % 10 == 1 && $number % 100 != 11)
                ? $forms[0]
                : (
            ($number % 10 >= 2 && $number % 10 <= 4 && ($number % 100 < 10 || $number % 100 >= 20))
                ? $forms[1]
                : $forms[2]
            );

and usage: pluralForm(days, [ 'день', 'дня', 'дней' ]) and so on.

Problem somewhere here: https://github.com/go-gitea/gitea/blob/master/options/locale/locale_ru-RU.ini#L1804

[lunny]

Please go to https://crowdin.com/project/gitea to correct that.

Sounds good, but, how gitea engine uses plural forms?

Sorry, GO is not my favorite language ;)

@KarelWintersky I don't know anything about the Russian language, but currently Gitea handles two cases: 1 day, n days. The first, singular, is the string 1d:

gitea/options/locale/locale_ru-RU.ini

Line 1797 in 149758c

1d=1 день

The second, plural, is days:

gitea/options/locale/locale_ru-RU.ini

Line 1804 in 149758c

days=%d дней

Perhaps дней is the wrong word for days? If that's the case, you should propose a different word in Crowdin. If the problem is different, please elaborate.

Otherwise, can you paste a screen capture showing the wrong string and what it should look like?

[KarelWintersky]

дней not a wrong for days generally.

However, the spelling of the word "days" depends on their number:

1 day -- 1 день
2 days -- 2 дня (3, 4)
5 days -- 5 дней (6..20)
21 days -- 21 день
22 days -- 22 дня (23..24)
25 days -- 25 дней (26..30)

Similarly with weeks, months, years.

The plural form changes depending on the numeral.

This packages, I think, can solve problem:

@lunny This is a complex case that can't be handled by Crowdin; the usual singular/plural duality does not apply to Russian. Perhaps we should re-label this issue? (kind/bug? kind/enhancement?)

[stale]

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs during the next 2 weeks. Thank you for your contributions.

[lunny]

So we could depend on package https://github.com/go-playground/locales and use %s on these translation strings about days.

I don't know GOlang syntax, but... I think, it looks like missed

PluralRuleOne
PluralRuleFew
PluralRuleMany

Lot of languages has more complex rules for plural form then English. From supported languages by gitea

Czech, Latvian, Lithuanian, Polish, Russian, Serbian, Ukrainian - have complex rules

French, Persian, Portuguese - are using singular for zero

Other supported languages have same rules as English or have same form for one and many, so they must duplicate the translation.

see https://unicode.org/cldr/charts/latest/supplemental/language_plural_rules.html

So, it should be better to rename this issue to add general support for plural forms of all these languages and incorporate some existing mechanism.

There are many other situations in Gitea, not just dates.
It is really hard to translate e.g. this in all these languages.

repo:pulls.num_conflicting_files_1 = %d conflicting file
repo:pulls.num_conflicting_files_n = %d conflicting files

Translators must chose form which is less wrong, but stil wrong.
