ActiveGo

New to Go on Windows

Question: 

I'm new to Go. I've installed ActiveGo. How do I get started?

Answer: 

Start here:
http://docs.activestate.com/activego/1.8/doc/code.html
The introduction will explain how your workspace is arranged. In case you missed it, your $GOPATH has already been set by the ActiveGo installer.

If you don't use Git already, you should install it and learn how to use it. Git is an essential supporting tool for coding in Go.

There's a simple HelloWorld program in the Go introduction.

ActiveGo sets up local documentation on your system as a document server. On the local ActiveGo documentation start page, there is an interactive Sandbox window labelled "Try Go". You will see the source code before it compiles. When you click "Run" the code compiles and displays the result in the box below the source code. There's a pull-down with a small set of sample Go snippets.

Multiple versions of Go

Question: 

Can I have ActiveGo and another distribution of Go installed together?

Answer: 

The ActiveGo-beta will set GOROOT, GOPATH, and PATH variables. The Golang distribution will also set GOROOT and PATH.

-ActiveGo will always be the default version of Go if both are on the system due to the ways both Go versions set up PATH. Neither ActiveGo nor Golang Go will remove the other distribution from PATH.

-Any value in GOROOT will be overwritten by both versions of Go when they install. The last version to install will be set up as the root. If you remove a version of Go, you will need to re-install/repair the other one to ensure that GOROOT is correct before you start using it.

-GOPATH is your personal workspace. Your workspace should be usable with either version of Go.
