Manual:Echo/pt-br

A extensão Echo fornece outro sistema de notificação para o MediaWiki.

Menções
Echo can send notifications to users mentioned in discussions; this feature is often referred to as "pinging". Linking to a user's page in a signed message, either directly or through a template, will trigger a mention notification for them. The technical details of this are laid out below.

Technical details
When generating mention events, Echo processes revision diffs chunk by chunk, to check when a user has added a new comment which should be searched for mentioned users to ping. As of this writing, for user mention notifications to work:


 * The diff chunk must be recognised as an addition of new lines of text, not a change to existing lines.
 * The user must sign his or her message.
 * The signature must contain a plain wiki link to the user's page, user talk page, or contributions page, on the local wiki; it cannot be embedded in a template.
 * In order for the signature to be recognised, the post must contain the exact same markup that writing  (and  ) generates.
 * The comment must either belong in its entirety to existing sections (the diff chunk of added lines must not contain new section headers), or start a new section (diff chunk starts with a new section header).  Only sections of level 2 and above count.
 * Links to mentioned users' pages may be embedded in templates or not, since the diff is template-expanded
 * The  and   variables expand to the empty string when Echo parses the diff.
 * If the number of detected to-be-pinged users exceeds 50, no notifications will be delivered.

Also, all markup is parsed with regular expressions; sufficiently tricky markup can trigger bogus results.
