The open-source Go plugin for JetBrains IDEs like IntelliJ IDEA, PHPStorm, WebStorm and so on. It works on both payed and free versions of the IDEs and tries to meet the expectations that an IntelliJ platform user from a language plugin as well as help people in their daily development activity using Go.
The plugin is available for free in the official plugin manager. While there are a couple of things to iron out, the plugin itself won't be considered stable until version 1.0 is released, it can already be used on production code, having most of the features of its competitors as well as bringing new ones to the table.
Combined with the free version of IntelliJ IDEA, the Community Edition, it will offer a powerful addition to those who seek to develop in Go both for normal applications and for Go on Google AppEngine websites.
