• Connect to and chat with any Discord server the bot is a member of via the command line
• Send and receive text messages, including basic info for attachments and embeds
• Basic command support (type /help to see a list of commands)
• Supports emojis (:emoji_name:) and user tagging (by tag or nickname)
• Colors user nicknames by role colors (as accurate as the console window allows)

Basic setup (in your main bot script):

const Discord = require('discord.js')
const client = new Discord.Client()
const consoleChat = require('./consoleChat.js')
...

client.on('ready', () => {
    ...
    consoleChat.startConsoleInput(client)
    ...
})

client.on('message', function(message) {
    consoleChat.onMessage(message)
    ...
})

client.login(YOUR_SECRET_TOKEN)
...

Anywhere you would use console.log(value):

...
consoleChat.println(value)
...
