Illerai:Grand Exchange Market Watch/Documentation
The Grand Exchange Market Watch (GEMW) grew from a need to track trading prices of the Grand Exchange without having to update the prices in the multiple articles for the same item. This article provides the documentation and technical background for editors to understand the workings of the GEMW.
Introduction
Transclusion (the use of the template functionality to include the same content in multiple articles without having to edit those articles separately) is used in the GEMW for an item's market price. This is achieved by having a separate namespace called Exchange: for the purpose of the GEMW.
By updating the price in only one template (e.g. Exchange:Ranarr seed), the new price will also appear in:
- Ranarr seed's article Infobox Item template
- the pages of the Grand Exchange Market Watch, such as Grand Exchange Market Watch/Farming
- another article such as Farming, where the prices of several items are compared
Updating the price of Ranarr seeds in Exchange:Ranarr seed will update the changes in the article Ranarr seed automatically. This is because the Infobox Item parameter |exchange = gemw calls {{GEPrice|Ranarr seed}} for the price (currently at 27,298 coins).
