Left to Right Programming
Programs Should Be Valid as They Are Typed I don’t like Python’s list comprehensions: text = "apple banana cherry\ndog emu fox" words_on_lines = [line.split() for line in text.splitlines()] Don’t get me wrong, declarative programming is good. However, this syntax has poor ergonomics. Your editor can’t help you out as you write it. To see what I mean, lets walk through typing this code. words_on_li
Robot - a fast functional library for creating Finite State Machines and Statecharts
Fast 1kB functional library for creating Finite State Machines # Robot Getting Started Why Finite State Machines With Robot you can build finite state machines in a simple and flexible way. import { createMachine, state, transition } from 'robot3'; const machine = createMachine({ inactive: state( transition('toggle', 'active') ), active: state( transition('toggle', 'inactive') ) }); export default
Lucy | A DSL for Finite State Machines
toggle.lucy state enabled { toggle => disabled } initial state disabled { toggle => enabled } out.js import { createMachine } from 'xstate'; export default function() { return createMachine({ initial: 'disabled', states: { enabled: { on: { toggle: 'disabled' } }, disabled: { on: { toggle: 'enabled' } } } }); } Install See the install page for detailed instructions on the various ways you can use L
Coding my Handwriting — Amy Goodchild
A familiar theme for me is dismissing an idea as being too much work and then later finding myself doing it anyway. That’s what happened here. A little while ago I created a block script in JavaScript, thinking that cursive would be too complex. But here I am, two months later, ready to talk about the cursive handwriting I’ve created. There is perhaps a lesson in that but let’s not dwell on it. Bl
TypeScript: Branded Types 🔧
PART 1: TypeScript Mapped Type Magic Ahoy there TypeScript warriors! 👋 Today we're extending our work in the TypeScript mapped types article to provide branding. The previous article discussed how to use TypeScript mapped types in a nominal rather than structural nature. type A = { x: number } type B = { x: number }This is a fancy way of saying TypeScript is structural by default, i.e. it will se
Introducing Strudel | Loophole Letters
The last couple of months, I've been hacking on Strudel, which is a live coding environment that brings the ideas of Tidal Cycles to the browser: In this post, I want to write about how it all started, and describe the general features of strudel from a technical point of view. Table of Contents How it started About the REPL About Patterns Pattern factories sequence stack more Pattern modifiers fa
Getting Started 🚀 Strudel
Welcome to the Strudel documentation pages! You’ve come to the right place if you want to learn how to make music with code. What is Strudel? With Strudel, you can expressively write dynamic music pieces. It is an official port of the Tidal Cycles pattern language to JavaScript. You don’t need to know JavaScript or Tidal Cycles to make music with Strudel. This interactive tutorial will guide you t
