# command-tree

A Racket package to handle tree-style (à la git) command line arguments

## Examples

This package allows you to write command line applications that behaves like this:

`$ git stash pop`  

`$ pimp my ride "green neons"`  

`$ ipod list all albums from 1969`  

`$ hello world --help`

# Install

`raco pkg install command-tree`

# Usage

```racket

#lang racket/base

(require command-tree)

;; ... define procedures git-clone, git-init, git-stash-apply...

;; write your available commands in a tree

(define git-commands

  `([clone ,git-clone]

    [init ,git-init]

    [push ,git-push]

    [remote (add ,git-remote-add)

            (rename ,git-remote-rename)

            (remove ,git-remote-remove)]

    [stash (list ,git-stash-list)

           (show ,git-stash-show)

           (drop ,git-stash-drop)

           (pop ,git-stash-pop)

           (apply ,git-stash-apply)]))

;; use the tree to parse the command line

(command-tree git-commands (current-command-line-arguments))

```

See the test submodule in main.rkt for a complete usage example.
