GoExitCodes

A simple experiment for adding an idiomatic way of handling exit codes in Go.

Background

Most of my development experience has been on Apple platforms, and this little repo was born from me missing some of Swift/ObjC's more idiomatic/expressive tendencies.

For example, when exiting from a CLI built in Swift, you would do something like:

exit(EXIT_SUCCESS)

or

exit(EXIT_FAILURE)

EXIT_SUCCESS and EXIT_FAILURE are just macros for 0 and 1, respectively, so nothing fancy at all, but it's just a more expressive way to represent exit codes.

Usage

At its simplest, you can use GoExitCodes like so:

import . "github.com/hisaac/GoExitCodes/exitcode"

func main() {
	exitCode := run()
	os.Exit(int(exitCode))
}

func run() ExitCode {
	if err := DoSomething(); err != nil {
		return Failure
	}
	return Success
}
