Olipa kerran pupu, se hassu pupu on.

ഒരിടത്തൊരു രസികന്‍ മുയലുണ്ടായിരുന്നു.

ஒரு முயல்குட்டி இருந்தது, அது ஒரு வேடிக்கையான முயல்குட்டி உள்ளது.

זה מצחיק אפילו בלי תרגום

Possible things to include:

[Motivation] "I18n is not an option"

• Don't schedule for later - start immediately.
• It doesn't just help speakers of other languages - it helps uncover bugs early.
• Give translators time to translate and to report issues
• Have time for fixing issues
• Don't say "It's only for the English Wikipedia" - It happened many times that it wasn't just for the English Wikipedia.

[Practical stuff] Message writing tips

• No lego
• Avoid "right"/"left"
• Avoid jargon, and if you really need it - document it.
• Having a glossary would be awesome.
• Good example: Wikidata (Wikibase) extensions
• Bad example? :)
• Avoid writing messages that assume the size of screen, button, table header. Translations can be much longer and much shorter. If you really-really need to have it, document it.

[Message documentation tips]

• Use {{msg-mw}} when needed
• Screenshots are supported
• Give examples with variables replaced
• What is it? Button text / page title / link / table header - it's important information
• Document everything, but especially:
• Adjectives - say what are they describing (can be masculine/feminine in other languages)
• Messages that use other messages or are related to them, with {{msg-mw}}
• For very short messages, say what part of speech it is - adjective, verb, noun, etc.

[Technical stuff] Tour on wfMessage (like, use numParams for numbers)

• wfMessage or $this->msg (depending on context (pun intented!))
• ->params ->numParams ->rawParams
• Pick one: plain, text, parse, escapes, parseAsBlock
• Tips on picking?..
• Tips of reviewing?..
• New code should accept Message objects (instead of string/array of keys/params)
• Write the whole message name. If you have to concatenate, add a comment with the full message wherever relevant.

New logging system

• Supports gender
• Supports flexible word order
• Flexible parameters
• Many logs yet to be converted (hardest part is to understand all the legacy parameter formats)

$entry = new ManualLogEntry( 'patrol', 'patrol' ); $entry->setTarget( $rc->getTitle() ); $entry->setParameters( self::buildParams( $rc, $auto ) ); $entry->setPerformer( $user ); $logid = $entry->insert(); if ( !$auto ) {

  $entry->publish( $logid, 'udp' );

}

Particular tips on using messages in JavaScript

• Required packages
• Limitations
• jQuery.i18n future
