Additional info

in uk.js I observe the change of the format from the last version:
in 27.1.6:

    "Delete file" : "Вилучити файл",
    "Delete folder" : "Вилучити каталог",

in 27.1.7:

    "_Delete file_::_Delete files_" : ["Вилучити файл","Вилучити файли","Вилучити файли","Вилучити файли"],
    "_Delete folder_::_Delete folders_" : ["Вилучити каталог","Вилучити каталоги","Вилучити каталоги","Вилучити каталоги"],

Is this something related to?

My guess here: We take translations from master / stable28 were that string is pluralized due to batch actions being possible.
But we should update changes like that to older stable branches.

Maybe @skjnldsv knows more about the CI that updates the translations?

Is this actually translated on transifex?

Sure :)

As said my guess it that we update translations from current master -> so the string is now pluralized and thus the frontend translate function can not translate it anymore.

[skjnldsv]

I don't remember how it works.
if that was the case, it would mean every non-master releases would have translations missing for years no?
I mean, we change a lot of apps and various strings...

[oleua]

"Delete file::Delete files" : ["Вилучити файл","Вилучити файли","Вилучити файли","Вилучити файли"],
"Delete folder::Delete folders" : ["Вилучити каталог","Вилучити каталоги","Вилучити каталоги","Вилучити каталоги"],

Is this formatting supported in 27.1.x?

[skjnldsv]

@blizzz @nickvergessen do you know more?

[nickvergessen]

Strings from all versions we translate are combined.

But the string looks a bit weird anyway as the number is not included?
Do you have a link to the respective source code?

28 and 29

server/apps/files/src/actions/deleteAction.ts

Line 90 in 12fe865

return n('files', 'Disconnect storage', 'Disconnect storages', nodes.length)

server/apps/files/src/actions/deleteAction.ts

Line 97 in 12fe865

return n('files', 'Delete file', 'Delete files', nodes.length)

27

server/apps/files/js/fileactions.js

Lines 784 to 786 in 9a4f2f1

	var deleteTitle = (type && type === 'file')
	? t('files', 'Delete file')
	: t('files', 'Delete folder')

So yes this is a problem of combining the strings, if it was singular previously and then the same string is provided as plural option we can not use it anymore in the frontend. (Because the translation key is merged into a plural version and thus we can not detect it anymore).

Two fixes possible:

1. Also change 27 and 26 to the plural version (easy)
2. Adjust our translation logic to somehow figure out the plural key and try that one as well. (harder)
