Overview

Package cmdutil contains utility methods that are useful for command-line programs.

• Variables
• func Err(a ...zero.Interface) (n int, err error)
• func Errf(format string, a ...zero.Interface) (n int, err error)
• func Errln(a ...zero.Interface) (n int, err error)
• func Fatal(a ...zero.Interface)
• func Fatalf(format string, a ...zero.Interface)
• func Fatalln(a ...zero.Interface)
• func Must(err error)

Variables

var FatalExitCode = 1

FatalExitCode is the exit code that all Fatal* methods exit with after printing.

Functions

func Err

func Err(a ...zero.Interface) (n int, err error)

Err is like fmt.Print, but writes to standard error.

func Errf

func Errf(format string, a ...zero.Interface) (n int, err error)

Errf is like fmt.Printf, but writes to standard error.

func Errln

func Errln(a ...zero.Interface) (n int, err error)

Errln is like fmt.Println, but writes to standard error.

func Fatal

func Fatal(a ...zero.Interface)

Fatal is like Err, but exits with an error code after printing.

func Fatalf

func Fatalf(format string, a ...zero.Interface)

Fatalf is like Errf, but exits with an error code after printing.

func Fatalln

func Fatalln(a ...zero.Interface)

Fatalln is like Errln, but exits with an error code after printing.

func Must

func Must(err error)

Must panics if err is not nil.

It is used to wrap side-effect-inducing function calls that return an error.
