Functions ¶
func BuildOptions ¶
BuildOptions 通过map构造出options
func ContainsOpt ¶
ContainsOpt 判断指定name的option是否存在
func GetOptWithEnv ¶
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 name>.<variable name>; 2. Environment arguments are in uppercase format, eg: GF_<package name>_<variable name>；
func GetWithEnv ¶
GetWithEnv 获取参数，如果命令行不存在则从环境变量中获取
Types ¶
type Parser ¶
type Parser struct {
// contains filtered or unexported fields
}
func Parse ¶
Parse creates and returns a new Parser with os.Args and supported options.
Note that the parameter <supportedOptions> is as [option name: need argument], which means the value item of <supportedOptions> indicates whether corresponding option name needs argument or not.
The optional parameter <strict> specifies whether stops parsing and returns error if invalid option passed.
func ParseWithArgs ¶
func ParseWithArgs(args []string, supportedOptions map[string]bool, strict ...bool) (*Parser, error)
ParseWithArgs creates and returns a new Parser with given arguments and supported options.
Note that the parameter <supportedOptions> is as [option name: need argument], which means the value item of <supportedOptions> indicates whether corresponding option name needs argument or not.
The optional parameter <strict> specifies whether stops parsing and returns error if invalid option passed.
func (*Parser) AutoRun ¶
AutoRun automatically recognizes and executes the callback function by value of index 0 (the first console parameter).
func (*Parser) BindHandle ¶
BindHandle registers callback function <f> with <cmd>.
func (*Parser) BindHandleMap ¶
BindHandleMap registers callback function with map <m>.
func (*Parser) ContainsOpt ¶
ContainsOpt checks whether option named <name> exist in the arguments.
func (*Parser) MarshalJSON ¶
MarshalJSON implements the interface MarshalJSON for json.Marshal.
