Nook

Nook is a command-line interface (CLI) application that allows you to manage key-value pairs. It provides functionality to add, delete, and retrieve key-value pairs using simple commands. This project uses the Click library for the CLI interface and pickle for data persistence. It can also be used programmatically as a libray.

Features

• Add key-value pairs.
• Delete key-value pairs.
• Retrieve values by key.

Usage

• Can be used as a quick database solution in development
• Can be used to store environment keys and possibly other config keys.

Installation

Using pip

  pip install nook

From github

To get started with nook, clone this repository and install the required dependencies.

nook delete --delete yourkey

Retrieving a Value

To retrieve a value by key, use the get_value command with the --getvalue (or -g) option.

add.callback('key','value')

getvalue.callback('key')

getvalue.callback('key')

delete.callback('key')
