mango is a man-page generator for the Go flag, pflag, cobra, coral, and kong packages. It extracts commands, flags, and arguments from your program and enables it to self-document.

Adapters

Currently the following adapters exist:

Usage with flag:

import (
    "flag"
    "fmt"

    "github.com/muesli/mango"
    "github.com/muesli/mango/mflag"
    "github.com/muesli/roff"
)

var (
    one = flag.String("one", "", "first value")
    two = flag.String("two", "", "second value")
)

func main() {
    flag.Parse()

    manPage := mango.NewManPage(1, "mango", "a man-page generator").
        WithLongDescription("mango is a man-page generator for Go.\n"+
            "Features:\n"+
            "* User-friendly\n"+
            "* Plugable").
        WithSection("Copyright", "(C) 2022 Christian Muehlhaeuser.\n"+
            "Released under MIT license.")

    flag.VisitAll(mflag.FlagVisitor(manPage))
    fmt.Println(manPage.Build(roff.NewDocument()))
}

Mango will extract all the flags from your app and generate a man-page similar to this example:

Usage with pflag:

import (
    "fmt"

    "github.com/muesli/mango"
    mpflag "github.com/muesli/mango-pflag"
    "github.com/muesli/roff"
    flag "github.com/spf13/pflag"
)

func main() {
    flag.Parse()

    manPage := mango.NewManPage(1, "mango", "a man-page generator").
        WithLongDescription("mango is a man-page generator for Go.").
        WithSection("Copyright", "(C) 2022 Christian Muehlhaeuser.\n"+
            "Released under MIT license.")

    flag.VisitAll(mpflag.PFlagVisitor(manPage))
    fmt.Println(manPage.Build(roff.NewDocument()))
}

Usage with cobra:

import (
	"fmt"

	mcobra "github.com/muesli/mango-cobra"
	"github.com/muesli/roff"
	"github.com/spf13/cobra"
)

var (
    rootCmd = &cobra.Command{
        Use:   "mango",
        Short: "A man-page generator",
    }
)

func main() {
    manPage, err := mcobra.NewManPage(1, rootCmd)
    if err != nil {
        panic(err)
    }

    manPage = manPage.WithSection("Copyright", "(C) 2022 Christian Muehlhaeuser.\n"+
        "Released under MIT license.")

    fmt.Println(manPage.Build(roff.NewDocument()))
}

Usage with coral:

import (
	"fmt"

	mcoral "github.com/muesli/mango-coral"
	"github.com/muesli/roff"
	"github.com/muesli/coral"
)

var (
    rootCmd = &coral.Command{
        Use:   "mango",
        Short: "A man-page generator",
    }
)

func main() {
    manPage, err := mcoral.NewManPage(1, rootCmd)
    if err != nil {
        panic(err)
    }

    manPage = manPage.WithSection("Copyright", "(C) 2022 Christian Muehlhaeuser.\n"+
        "Released under MIT license.")

    fmt.Println(manPage.Build(roff.NewDocument()))
}
