Hands-On GUI Application Development in Go

Managing platform specifics

Back in Chapter 3, Go to the Rescue!, we saw that the Go compiler has built-in support for the conditional inclusion of source files based on a system of environment variables and build tags.

To do so, we will use a variation of the conditional build – using well-named files instead of build tags (as used in Chapter 11, Navigation and Multiple Windows).
