man
command to generate manpages using mango1 - Completions: Adds a

To use it, invoke fang.Execute
passing your root *cobra.Command
:
package main
import (
"os"
"github.com/charmbracelet/fang"
"github.com/spf13/cobra"
)
func main() {
cmd := &cobra.Command{
Use: "example",
Short: "A simple example program!",
}
if err := fang.Execute(context.TODO(), cmd); err != nil {
os.Exit(1)
}
}
That's all there is to it!

Default cobra man pages generates one man page for each command. This is generally fine for programs with a lot of sub commands, like git, but its an overkill for smaller programs. Mango also uses roff directly instead of converting from markdown, so it should render better looking man pages. ↩
