How To Install Go Plugin For IntelliJ Idea 15

There is a number of good tools that support Go developers in writing code. But three of them are the most popular in the field: Vim, Sublime, IntelliJ Idea. I use all of them, but the most feature rich and my favourite one is IntelliJ Idea. In this post we will set up Intellij Idea for development in Go.

Bottom line

Configuring Intellij Idea to support development in Go is not a breeze yet, especially if you do not have prior Idea experience. But after short pain, you get the best tool support for Go in action. Especially you will love Idea if you refactor often. Idea provides lot of short cuts for many tasks like compile, run, create new file and so on - use them.
