defmodule Default.Behaviour do
  @moduledoc """
  Creates a behaviour that carries its own default implementation.

  When used into a behaviour module, when that module in turn is used, all functions
  defined on it are given to the using module.
  
  This allows you to have concrete implementations of the behaviour's default functionality
  for testing, unlike cramming them all into a __using__ macro.

✨ Download Slack Emoji ✨

Quick way to export your Slack team's emoji (concurrently!)

Prerequisites

• aria2 (brew install aria2)
• ruby

1. Create an API token for your Slack team

I certainly have plenty of ar callbacks, wondering what patterns you use to avoid controller bloat or factories for every model?

Sometimes option 1) Extract the callback to its own method and call it:

# File app/models/user.rb
class User < ApplicationRecord

-  after_commit { |user| Mailer.registration_confirmation(user).deliver_later }, on: :create
+  def send_registration_confirmation

# Docker Version Manager wrapper for *nix
# Implemented as a POSIX-compliant function
# Should work on sh, dash, bash, ksh, zsh
# To use, source this file from your bash profile

begin # This ensures the entire script is downloaded
    set DVM_SCRIPT_SOURCE $_

    # __dvm_has() {
    #   type "$1" > /dev/null 2>&1

Extracting Emoji From Slack!

Slack doesn't provide an easy way to extract custom emoji from a team. (Especially teams with thousands of custom emoji) This Gist walks you through a relatively simple approach to get your emoji out.

If you're an admin of your own team, you can get the list of emoji directly using this API: https://api.slack.com/methods/emoji.list. Once you have it, skip to Step 3

HOWEVER! This gist is intended for people who don't have admin access, nor access tokens for using that list.
