Functions

func ContainsOpt

func ContainsOpt(name string) bool

ContainsOpt checks whether option named `name` exist in the arguments.

func GetArg

func GetArg(index int, def ...string) string

GetArg returns the argument at `index`.

func GetArgAll

func GetArgAll() []string

GetArgAll returns all parsed arguments.

func GetOpt

func GetOpt(name string, def ...string) string

GetOpt returns the option value named `name`.

func GetOptAll

func GetOptAll() map[string]string

GetOptAll returns all parsed options.

func GetOptWithEnv

func GetOptWithEnv(key string, def ...string) string

GetOptWithEnv returns the command line argument of the specified `key`. If the argument does not exist, then it returns the environment variable with specified `key`. It returns the default value `def` if none of them exists.

Fetching Rules: 1. Command line arguments are in lowercase format, eg: gf.package.variable; 2. Environment arguments are in uppercase format, eg: GF_PACKAGE_VARIABLE；

func Init

func Init(args ...string)

Init does custom initialization.

func ParseUsingDefaultAlgorithm

func ParseUsingDefaultAlgorithm(args ...string) (parsedArgs []string, parsedOptions map[string]string)

ParseUsingDefaultAlgorithm parses arguments using default algorithm.
