Wikipedia and Lua

From Wired.com:

It began as the encyclopedia anyone can edit. And now it’s also the encyclopedia anyone can program. 

As of this weekend, anyone on Earth can use Lua — a 20-year-old programming language already championed by the likes of Angry Birds and World of Warcraft — to build material on Wikipedia and its many sister sites, such as Wikiquote and Wiktionary. Wikipedia has long offered simple tools that let tens of thousands of volunteer editors reuse little bits of text across its encyclopedia pages, but this is something different. 

“We wanted to provide editors with a real programming language,” says Rob Lanphier, the director of platform engineering at the Wikimedia Foundation, the not-for-profit that oversees the online encyclopedia. “This will make things easier for editors, but it will also be significantly faster.”
