Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

⚠️ Notice

This guide is for discord.py 1.7 version. In upcoming v2.0, Webhooks were greatly overhauled and in fact simplified a lot. They no longer require adapters. Usage of webhooks is now quite straight forward. As such, this guide is now outdated and should not be followed.

Furthermore, this guide is focused on discord.py. No support for forks are covered in this guide.

Basic Webhooks Example using Discord.py (Rewrite)

Webhooks are a great way to send messages to Discord without having a bot account. You just need a webhook URL and just do a POST request on that URL and the message will be sent to discord.

Webhooks can also be used if your bot has to send messages to a channel a lot. For example, If your bot has event logging so everytime having to fetch channel and sending can be slow so you can use some webhook magic.

Upgrade to at least 0.8.4

Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!

The advantages of versions 0.8.* over <0.8.0 are:

Safemath by default from 0.8.0 (can be more gas efficient than some library based safemath).
Low level inliner from 0.8.2, leads to cheaper runtime gas. Especially relevant when the contract has small functions. For

	%matplotlib inline
	#image is a numpy array
	imshow(image)

	##Another way in colab is...

	cv2_imshow(image)
