A little while ago Raymond Camden wrote about the recent updates to the Brackets editor. Brackets is an open source project focused on web standards and built with web technologies. It has a narrow focus and therefore may not have a particular feature you’ve come to depend upon. Luckily, Brackets ships with a powerful extension API that lets you add any number of new features. In this article, he's going to discuss this API and demonstrate how you can build your own extensions.
It is crucial that you remember that Brackets is in active development. This article is being written in December of 2013. It is certainly possible that the code demonstrated below is now out of date. Keep that in mind and be sure to check the wiki for the latest updates to the extension API.
