Making Impossible States Impossible in ReasonML

Introduction

If you have already seen Richard Feldman's talk entitled "Making Impossible States Impossible" or have read "Designing with types: Making illegal states unrepresentable" then you can skip the explanations and just head straight to the Reason examples.

This post is intended to display how to model your Reason Application to prevent creating impossible states. The benefits of being able to design a feature in this way include avoiding having to deal with complex test scenarios regarding defined business rules and a clear documentation of what is possible just by looking at the type definition. Long story short, let's see how this all works by implementing an example.

Glob Up and Running

To test a glob pattern go over to globtester and play around with creating your own file structure online, it's super easy to get started that way.

If you want to test out a glob pattern in the terminal use echo followed by the pattern, for instance.

echo **/*.js

idkjs

open ReasonReact;
open Utils;


type state = {
  shown : bool,
  value : string
};

let file_dialog = ReasonReact.reducerComponent("InputDialog");

    };
    var addProperty = function(item,propName,value) {
        if( typeof(value)==='string' )
            value = value.trim();
        if( Array.isArray(item[propName]) )

SQLite-based Points Bot

This is the example code for This Guide. Please read that guide to understand the code provided here.

On the other hand, if you know what you're doing, here's a quick how-to:

• In an admin command prompt or powershell, run npm i -g --production windows-build-tools.
• Close all open command prompts for your bot, or the following won't work.
• npm i discord.js better-sqlite3
• Create app.js and config.json per below.
• Make sure to get your bot token in the config.json.
