A quick guide to write a very very simple "ECHO" style module to redis and load it. It's not really useful of course, but the idea is to illustrate how little boilerplate it takes.
Step 1: open your favorite editor and write/paste the following code in a file called module.c
#include "redismodule.h"
/* ECHO <string> - Echo back a string sent from the client */
int EchoCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {
Minecraft mods, especially mods which change the client, are by and large written with Forge. If you visit their website, you'll be greeted abruptly by a mysterious message at the top of an SMF forum, with no clear path towards actually... making a mod. I'm documenting here the steps I went through to get started, in the hopes of helping the next person have an easier time of it.
I'll be using Scala for this guide, but it should be fairly easy to adapt these instructions to any JVM language (e.g. clojure or if you're feeling masochistic, Java). I'm also developing on OS X, so some of the commands will be a little different if you're on Linux or Windows. I'm assuming you have some proficiency with your operating system, so I won't go into details about how to adapt those commands to your system.
Minecraft doesn't have an official mod API (despite early [promises](http://notch.t

First, I would google for an image that represented what I had to draw. Then ran this code in pry to convert it into a set of x, y coordinates that should be dark:
require 'chunky_png'
canvas = ChunkyPNG::Canvas.from_file('scarface.png').grayscale
| #!/usr/bin/env ruby | |
| require 'selenium-webdriver' | |
| wd = Selenium::WebDriver.for :remote, url: 'http://10.3.1.7:4444/wd/hub', desired_capabilities: :chrome | |
| wd.navigate.to 'https://snipt.net/restrada/python-selenium-workaround-for-full-page-screenshot-using-chromedriver-2x/' | |
| # Get the actual page dimensions using javascript | |
| # | |
| width = wd.execute_script("return Math.max(document.body.scrollWidth, document.body.offsetWidth, document.documentElement.clientWidth, document.documentElement.scrollWidth, document.documentElement.offsetWidth);") |
These are for the combined vim-sexp (https://github.com/guns/vim-sexp) and vim-sexp-mappings-for-regular-people (https://github.com/tpope/vim-sexp-mappings-for-regular-people) plugins. vim-sexp is neat on its own but Tim Pope makes common stuff much easier.
Note that some vim-sexp functionality depends on <LocalLeader> mappings. This is a different leader key than the global leader, and is the variable maplocalleader (instead of mapleader). To see if you have this set, use :echo maplocalleader; if it errors out you'll need to set it, otherwise it will echo the key. If you want to set your LocalLeader to <Space>, you'll need two commands in your .vimrc, since by default <Space> is bound to <Right> in normal mode:
nnoremap <Space> <Nop>
let maplocalleader=" "

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.
