In the generated manpage, groups whose options are all hidden still have their header printed

[chipaca]

As promised, here's the bug: given

package main

import "os"
import "github.com/jessevdk/go-flags"

type options struct {
	A bool `short:"a" description:"align graviton beams"`
	G struct {
		W bool `long:"foo" description:"count woodchucks" hidden:"yes"`
	} `group:"Hidden options"`
	Z bool `short:"z" description:"engage reverse thrusters"`
}

func main() { flags.NewParser(&options{}, 0).WriteManPage(os.Stdout) }

you get

$ GOPATH=~/canonical/snappy/ go run /tmp/bug3.go cmd | MANWIDTH=60 man  -l -  | cat

Can you confirm this fixed?

Yes:

$ cat /tmp/bug3.go 
package main

import "os"
import "github.com/jessevdk/go-flags"

type options struct {
	A bool `short:"a" description:"align graviton beams"`
	G struct {
		W bool `long:"foo" description:"count woodchucks" hidden:"yes"`
	} `group:"Hidden options"`
	Z bool `short:"z" description:"engage reverse thrusters"`
}

func main() { flags.NewParser(&options{}, 0).WriteManPage(os.Stdout) }
$ go run /tmp/bug3.go | man -l - | cat
