[mediawiki/core@master] MessagesRue.php: Add $linkTrail

https://gerrit.wikimedia.org/r/777401

@Engelseziekte Hello. @Amire80 has some questions regarding your proposed linktrail:

what is the source for these particular letters? Is this the standard alphabet?

Could you please clarify?

Thanks

Checking Rusyn language#Alphabet on Wikipedia, it would appear that the correct link trail should be:

$linkTrail = '/^([a-zaбвгґдеєёжзіїиыйклмнопрстуфхцчшщюяьъѣӱô]+)(.*)$/sDu';

Why not just put something along the lines of (\p{Cyrillic}|\p{Latin})?

I've reviewed all Messages$Lang.php pages and I can't find such a syntax being used :)

Latin should be covered by the initial a-z and the rest are the letters of the Rusyn language alphabet as provided by @Engelseziekte and checked on Wikipedia (plus ѣ ӱ ô as requested). I feel that should work?

I've also seen some files using а-я to I guess cover all Cyrillic. Maybe the sytax could be shortened by:

$linkTrail = '/^([a-zа-яьъѣӱô]+)(.*)$/sDu';

(partially used in messagesKk_cyrl.php).

а-я is not all Cyrillic, it is basically Russian aphabet. For Ukrainian we have to use something along the lines of а-яієїґ.

Do you think:

$linkTrail = '/^([a-zа-яьъѣӱô]+)(.*)$/sDu';

as proposed above, would work?

It depends on what you want to include. ії is not in that range for instance, I believe.

Yes, technically, but I'd love an explanation about the letters ѣӱô. AFAIK, they are not part of the alphabet. And the letters і and ї appear to be missing.

Not sure about ӱô, which were requested by @Engelseziekte above. As for ѣ, https://en.wikipedia.org/wiki/Rusyn_language#Usage_notes says:

Until World War II, the letter ѣ (їть or yat') was used (...). This letter is still used in part of the articles in the Rusyn Wikipedia.

so I think it makes sense to add it to the LinkTrail if they're still using it IMHO.

Correct. It should be, I think:

$linkTrail = '/^([a-zа-яіїьъѣӱô]+)(.*)$/sDu';

(notwithstanding the ѣӱô question which I am not able to answer)

... Or to thoroughly check why are they using this letter. If it's not used in other publications in this language, this wiki may be violating the language policy: The Wikimedia Foundation does not seek to develop new linguistic entities.
