If you import - pflag under the name "flag" then all code should continue to function - with no changes. - - import flag "github.com/ogier/pflag" - - There is one exception to this: if you directly instantiate the Flag struct - there is one more field "Shorthand" that you will need to set. - Most code never instantiates this struct directly, and instead uses - functions such as String(), BoolVar(), and Var(), and is therefore - unaffected. - - Define flags using flag.String(), Bool(), Int(), etc. - - This declares an integer flag, -flagname, stored in the pointer ip, with type *int. - var ip = flag.Int("flagname", 1234, "help message for flagname") - If you like, you can bind the flag to a variable using the Var() functions. - var flagvar int - func init() { - flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname") - } - Or you can create custom flags that satisfy the Value interface (with - pointer receivers) and couple them to flag parsing by - flag.Var(&flagVal, "name", "help message for flagname") - For such flags, the default value is just the initial value of the variable. - - After all flags are defined, call - flag.Parse() - to parse the command line into the defined flags. - - Flags may then be used directly. If you're using the flags themselves, - they are all pointers; if you bind to variables, they're values. - fmt.Println("ip has value ", *ip) - fmt.Println("flagvar has value ", flagvar) - - After parsing, the arguments after the flag are available as the - slice flag.Args() or individually as flag.Arg(i). - The arguments are indexed from 0 through flag.NArg()-1. - - The pflag package also defines some new functions that are not in flag, - that give one-letter shorthands for flags. You can use these by appending - 'P' to the name of any function that defines a flag. - var ip = flag.IntP("flagname", "f", 1234, "help message") - var flagvar bool - func init() { - flag.BoolVarP("boolname", "b", true, "help message") - } - flag.VarP(&flagVar, "varname", "v", 1234, "help message") - Shorthand letters can be used with single dashes on the command line. - Boolean shorthand flags can be combined with other shorthand flags. - - Command line flag syntax: - --flag // boolean flags only - --flag=x - - Unlike the flag package, a single dash before an option means something - different than a double dash. Single dashes signify a series of shorthand - letters for flags. All but the last shorthand letter must be boolean flags. - // boolean flags - -f - -abc - // non-boolean flags - -n 1234 - -Ifile - // mixed - -abcs "hello" - -abcn1234 - - Flag parsing stops after the terminator "--". Unlike the flag package, - flags can be interspersed with arguments anywhere on the command line - before this terminator. - - Integer flags accept 1234, 0664, 0x1234 and may be negative. - Boolean flags (in their long form) accept 1, 0, t, f, true, false, - TRUE, FALSE, True, False. - Duration flags accept any input valid for time.ParseDuration. - - The default set of command-line flags is controlled by - top-level functions. The FlagSet type allows one to define - independent sets of flags, such as to implement subcommands - in a command-line interface. The methods of FlagSet are - analogous to the top-level functions for the command-line - flag set. -*/ -package pflag - -import ( - "errors" - "fmt" - "io" - "os" - "runtime" - "sort" - "strings" -) - -// ErrHelp is the error returned if the flag -help is invoked but no such flag is defined. -var ErrHelp = errors.New("pflag: help requested") - -// ErrorHandling defines how to handle flag parsing errors. -type ErrorHandling int - -const ( - ContinueOnError ErrorHandling = iota - ExitOnError - PanicOnError -) - -// A FlagSet represents a set of defined flags. -type FlagSet struct { - // Usage is the function called when an error occurs while parsing flags. - // The field is a function (not a method) that may be changed to point to - // a custom error handler. - Usage func() - - name string - parsed bool - actual map[string]*Flag - formal map[string]*Flag - shorthands map[byte]*Flag - args []string // arguments after flags - exitOnError bool // does the program exit if there's an error? - errorHandling ErrorHandling - output io.Writer // nil means stderr; use out() accessor - interspersed bool // allow interspersed option/non-option args -} - -// A Flag represents the state of a flag. -type Flag struct { - Name string // name as it appears on command line - Shorthand string // one-letter abbreviated flag - Usage string // help message - Value Value // value as set - DefValue string // default value (as text); for usage message -} - -// sortFlags returns the flags as a slice in lexicographical sorted order. -func sortFlags(flags map[string]*Flag) []*Flag { - list := make(sort.StringSlice, len(flags)) - i := 0 - for _, f := range flags { - list[i] = f.Name - i++ - } - list.Sort() - result := make([]*Flag, len(list)) - for i, name := range list { - result[i] = flags[name] - } - return result -} - -func (f *FlagSet) out() io.Writer { - if f.output == nil { - return os.Stderr - } - return f.output -} - -// SetOutput sets the destination for usage and error messages. -// If output is nil, os.Stderr is used. -func (f *FlagSet) SetOutput(output io.Writer) { - f.output = output -} - -// VisitAll visits the flags in lexicographical order, calling fn for each. -// It visits all flags, even those not set. -func (f *FlagSet) VisitAll(fn func(*Flag)) { - for _, flag := range sortFlags(f.formal) { - fn(flag) - } -} - -// VisitAll visits the command-line flags in lexicographical order, calling -// fn for each.
