Quick Example

package main

import (
    "fmt"
    "os"

    "github.com/JamesPatrickGill/applause"
)

func main() {
    // Define your CLI
    cmd := applause.NewCommand("greet").
        Version("1.0.0").
        About("A simple greeting application").
        Arg(applause.NewArg("name").Help("Name to greet")).
        Arg(applause.NewArg("greeting").Short("g").Long("greeting").Help("Custom greeting"))

    // Parse arguments
    matches := cmd.GetMatchesFrom(os.Args)

    // Get values
    name := "World"
    if n, ok := matches.GetPositional(0); ok {
        name = n
    }

    greeting := "Hello"
    if g, ok := matches.GetOne("greeting"); ok {
        greeting = g
    }

    fmt.Printf("%s, %s!\n", greeting, name)
}

Usage:
