La Extensión:Echo provee otro sistema de notificaciones para MediaWiki.


Echo puede enviar notificaciones a usuarios mencionados en discusiones; esta característica es usualmente llamada hacer un ping o enviar un ping. El hecho de mencionar a un usuario en un mensaje firmado, ya sea directamente o a través de una plantilla, hará que a ese usuario le llegue una notificación. Los detalles técnicos se mencionan abajo. 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.

Detalles técnicos

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 their message.


    • The signature must contain a plain wiki link ([[ ]]) to the user's page, user talk page, or contributions page, on the local wiki; the signature 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)[4][5], or start a new section (diff chunk starts with a new section header).

[6][7] Only sections of level 2 and above count.[8]

  • Links to mentioned users' pages may be embedded in templates or not, since the diff is template-expanded


  • 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.
