Getting Started

Codearena is a tool to aid in accessibility in the classroom.

Download the project from courseweb. It is a zip file consisting of two folders: codearena-api and codearena-client. Codearena-api is the Erlang server and codearena-client is the web interface.

Database Setup

This application uses CouchDB to store the code arenas. To set this up, create a database called arenas.

Dependencies:

• couchdb (installed and running)

Emily's List of Most Used Frontend Developer Command Line Commands

This is a growing list of the (mostly) Unix-like commands that I use the most while working on frontend projects. When I use the word "print" below, I probably mean log something to the terminal. Some commands are prefix by $ to show it's a command line command - don't actually type the $.

The Basics

Command	Description	Note
$ pwd	Print current directory
$ ls -a	Lists everything in the current directory, including hidden files (-a).	This lets you makes sure you can see your .gitignore, .bashrc, etc
$ mkdir example && cd $_	Makes a new directory and immediately goes into it.
$ mkdir -p example	Makes a new directory IF one of the same name doesn't already exist.
