go vet and golint
Golang implementation of docopt 0.6.1+fix
import “github.com/docopt/docopt.go” and then run go get.
func docopt.Parse(doc string, argv []string, help bool, version string, optionsFirst bool)
(args map[string]interface{}, err error)
Parse argv based on command-line interface described in doc.
docopt creates your command-line interface based on its description that you pass as doc. Such description can contain --options, , commands, which could be [optional], (required), (mutually | exclusive) or repeated...
doc Description of your command-line interface.
argv Argument vector to be parsed. os.Args[1:] is used if nil.
help Set to false to disable automatic help on -h or --help options..
version If set to something besides an empty string, the string will be printed if --version is in argv.
optionsFirst Set to true to require options precede positional arguments, i.e. to forbid options and positional arguments intermix..
args, map[string]interface{}. A map, where keys are names of command-line elements such as e.g. “--verbose” and “”, and values are the parsed values of those elements. interface{} can be bool, int, string, []string.
err, error. Either *docopt.LanguageError, *docopt.UserError or nil
package main
import (
"fmt"
docopt "github.com/docopt/docopt.go"
)
func main() {
usage := `Naval Fate.
Usage:
naval_fate ship new <name>...
naval_fate ship <name> move <x> <y> [--speed=<kn>]
naval_fate ship shoot <x> <y>
naval_fate mine (set|remove) <x> <y> [--moored|--drifting]
naval_fate -h | --help
naval_fate --version
Options:
-h --help Show this screen.
--version Show version.
--speed=<kn> Speed in knots [default: 10].
--moored Moored (anchored) mine.
--drifting Drifting mine.`
arguments, _ := docopt.Parse(usage, nil, true, "Naval Fate 2.0", false)
fmt.Println(arguments)
}
All tests from the python version have been implemented and all are passing.
New language agnostic tests have been added to test_golang.docopt.
To run them use go test.
