Summary

The more operating systems your application supports, the more complicated it will get. Hopefully armed with the knowledge of some supportive packages for developing independently of the platform, you’ll feel confident that your application will run similarly across different operating systems. Also, by checking the runtime operating system and even separating code into separate operating system-specific files with build tags, you have at least a couple of options for defining how to organize your code. This chapter goes more in-depth than may be necessary, but hopefully, it inspires you.

Building for multiple operating systems will expand the usage of your command-line application. Not only can you reach Linux or Unix users but also Darwin and Windows users as well. If you want to grow your user base, then building an application to support more operating systems is an easy way to do so.

In the next chapter, Chapter 8, Building for Humans Versus Machines, we&...
