Overview

The habu is Cobra 's very lightweight router.
Cobra requires command instances to be bound with AddCommand, but it reduces this effort.
If you want to separate packages for different subcommands, you don't have to worry about circular references to parent and child commands.

Example

Example of matching a subcommand with a directory.

my/package/cmd/sub/xxx.go

package sub

import (
    "github.com/spf13/cobra"
    "github.com/nanasi880/habu"
)

var command = &cobra.Command {
    Use: "sub",
}

func init () {
    habu.AddCommand(command, "/root")
}

my/package/cmd/xxx.go

package cmd

import (
    "github.com/spf13/cobra"
    "github.com/nanasi880/habu"
    _ "my/package/cmd/sub"
)

var rootCommand = &cobra.Command {
    Use: "root",
}

func init () {
    habu.AddCommand(rootCommand, "/")
}

my/package/main.go

package main

import (
    "os"
    
    "github.com/nanasi880/habu"
    _ "my/package/cmd"
)

func main() {
    err := habu.Execute()
    if err != nil {
        os.Exit(1)
    }
}
