Programming in Go by Mark Summerfield

ISBN: 0321774639

Copyright © 2011-12 Qtrac Ltd.

All the book's examples are designed to be educational, and many are also designed to be useful. I hope that you find them helpful, and are perhaps able to use some of them as starting points for your own projects.

On Unix-like systems (e.g., Linux, FreeBSD, Mac OS X), once you have installed Go, you can build all the examples in one go by executing:

$ cd $HOME/goeg
$ ./build.sh

On Windows it works similarly:

C:\>cd goeg
C:\goeg>build.bat

The build.sh (Unix) or build.bat (Windows) script sets GOPATH temporarily just for the build and uses the go command (go build); both assume that the go command (i.e., Go's bin directory) is in the PATH which it will be if you installed a binary version.

If you want to build the examples individually and build your own Go programs you will need to set GOPATH. This can be done temporarily by running the accompanying gopath.sh (Unix) or gopath.bat (Windows) script (after editing to change any paths to match your setup), or permanently by adding the export lines from gopath.sh to your .bashrc file or on Windows by creating a Go-specific console shortcut: see gopath.sh or gopath.bat for more information.
