Module:NPP backlog

Module documentation[view] [edit] [history] [purge]

This module retrieves the size of the backlog at new pages patrol at the start (UTC) of a given day. It uses the data compiled by User:MusikBot at Wikipedia:New pages patrol/Backlog chart/daily.

Note that the data is limited to the last c. 6 months.

Usage

Number of articles in the backlog on date (YYYY-MM-DD format):

{{#invoke:NPP backlog|articles|date}}

Difference between N and the articles backlog on date:

{{#invoke:NPP backlog|diff|N|date}}

If there is no data for date, the module will attempt to estimate by working backwards to the first date with data available. By default, this estimation assumes a one-day difference is being calculated. If not, specify a delta value in days:

{{#invoke:NPP backlog|diff|N|date|delta}}
