#024 World! in Go

exploring Go with the simplest example

Notes

This simple example demonstrates a few Go features:

• package names. Executable commands must always use package main.
• placing packages in unique import paths (lck/hello, lck/stringthings)
• conventional project structure: src, pkg, bin folders
• compile and build without makefiles (go install ..)
• conventions for unit testing

Running the Example

Set the GOPATH to the folder containing the src. Here I’m running from the folder itself:

$ export GOPATH=$(pwd)

Run the tests:

$ go test lck/stringthings
ok    lck/stringthings  0.006s

Compile and run the executable it produces in the bin folder:

$ go install lck/hello
$ bin/hello
Hola Mundo
odnuM aloH
