Flags

Flags provides a simple multicommand package built ontop of the internal flag Go/Golang package.

See Flags Docs for more.

If only one command is provided then Flags treats that command like the default command to be runned when argument is giving with no command name.

Example

import (
	"errors"

	"github.com/influx6/faux/flags"
)

func main() {
	flags.Run("sitecrawler", flags.Command{
		Name:      "crawl",
		ShortDesc: "Crawls provided website URL returning json sitemap.",
		Desc:      "Crawl is the entry command to crawl a website, it runs through all pages of giving host, ignoring externals links. It prints status and link connection as json on a per link basis.",
		Usages:    []string{"sitecrawler crawl https://monzo.com"},
		Flags: []flags.Flag{
			&flags.IntFlag{
				Name:    "depth",
				Default: -1,
				Desc:    "Sets the depth to crawl through giving site",
			},
		},
		Action: func(ctx flags.Context) error {
			if len(ctx.Args()) == 0 {
				return errors.New("Must provide website url for crawling. See examples section")
			}

			return nil
		},
	})
