Extension:CentralNotice/pt

A extensão CentralNotice distribui anúncios (normalmente na forma de faixas) para as wikis da Wikimedia. It is used heavily by the Fundraising team to solicit donations, and for announcements of interest to Wikimedia communities and users. CentralNotice can target announcements by country, language, project, device and logged-in status.

This page has information for CentralNotice developers and wiki administrators who want to install CentralNotice on their own sites. To learn how to create and configure CentralNotice campaigns, please see Help:CentralNotice on Meta-Wiki. For information about the CentralNotice setup on the Wikimedia Foundation's cluster, see CentralNotice on Wikitech.

CentralNotice allows central distribution of announcements to many wikis (called subscribing wikis) from a central wiki (the infrastructure wiki). If you only need to post messages to a single wiki, consider using Sitenotice instead.

If the  cookie is pre-populated, however, its value will be used. For local development, you can enable a client-side implementation that uses https://freegeoip.net as follows. For more information, see #GeoIP lookup.

Configuração rápida de programadores
For most development tasks, you can use a single wiki in both infrastructure and subscribing roles. Following are sample lines to include in. (See notes in comments.)

All code that runs on subscribing wikis should be smoke-tested with, to ensure they work on the mobile version of the site.

Conceitos de desenho
From a user facing perspective, the high level CentralNotice objects are campaigns (a.k.a. notices) and banners (a.k.a. templates). These are affected by the back end concepts of selectors and allocation.

The user status, device type, UI language selectors are applied to banners. All banners in a category share user side cookies, such as the hiding cookie that is set when a user clicks a banner close button. The project, country and content language selectors apply at the campaign level. The system allows as many active campaigns at the same time as you want dynamically calculating an allocation for each banner in an active campaign. Campaigns are defined as active if the central wiki time is greater than the campaign start time, less than the campaign end time, and the campaign is marked as enabled. Buckets are yet another selector, and weight affects the relative allocation of banners inside a campaign. Higher priority campaigns will get a greater allocation of page views. This allows, for example, different banners to be shown to logged in versus logged out users in Argentina browsing Wikipedia in English.
 * Banner — a single block of translatable html/wikitext/css/javascript that will display at the top of pages.
 * Banners may be grouped by category.
 * Campaign — a collection of banners.
 * Banners in a campaign are assigned a bucket and weight.
 * There are four priority levels in CentralNotice.
 * Campaigns may be locked which will prevent editing and deletion of the campaign; but not the banners inside a campaign.
 * Selector — any property which may be filtered on for the purposes of allocation.
 * A selection vector is the complete set of selectors a user presents to the central wiki when requesting a banner.
 * Allocation — The chance a banner will be shown to a user under a given selection vector.

GeoIP lookup
By default, CentralNotice has no client-side GeoIP lookup service configured. This is optimised for the Wikimedia Foundation production configuration where Varnish populates the  cookie from the server-side. (See Geolocation.) You can configure CentralNotice to use a custom data source client-side through the  configuration variable. This variable expects the name of a ResourceLoader module that exports a function. The function will be called without parameters and should return a Promise that resolves with an object containing the following properties:


 * country: string - Two-letter country code.
 * region: string - Implementation specific.
 * city: string - City name.
 * lat: number.
 * lon: number.

Utilização
Full usage instructions can be found at meta:Help:CentralNotice.

(TODO: move and expand this snippet)


 * Each banner has its banner definition stored in MediaWiki:Centralnotice-template-&lt;name>
 * All of its messages are stored below the banner defined in MediaWiki:Centralnotice-template-&lt;name>-&lt;message>/&lt;language_code>

Nova Campanha

 * 1) Load Special:CentralNotice

 * 1) If all looks well then set this campaign to enabled and it will show at the corresponding time.

Overriding selection
Add any of the following URL parameters to preview a specific banner, defeat "diet" schemes, or debug pseudorandom banner selection.


 * banner
 * You can test a banner directly on any wiki by adding  to the end of the URL.


 * randomcampaign
 * A decimal number between 0 and 1, to be used as the "random" seed for choosing a campaign.


 * randombanner
 * A decimal number between 0 and 1, to be used as the "random" seed for choosing a banner among banners available in the chosen campaign.


 * country
 * Override the country code, before filtering to geotargeted campaigns. Accepts two-character ISO 3166-1 codes.


 * uselang
 * Its usual meaning in MediaWiki, this determines which banners you may be shown. Beware of content language vs. user language.


 * force
 * Override any banner hiding code, show the banner.


 * reset
 * Zero out any cookies being used to customize banner display (e.g. delivered impression count).

Por exemplo,


 * https://en.wikipedia.org/wiki/Special:Random?banner=B18WMDE_authors_02_180801_2&uselang=en&force=1
 * https://it.wikisource.org/wiki/Speciale:RandomRootpage?randomcampaign=0.142
