envsource

⚠️ NOTE (20.5.2023): I don't really use this function at all anymore since there are now tools such as Taskfile, which reads the .env file for me sparing me the need to pollute my session with environment variables.

I've been using Fish shell for years which is great and all, but one thing that has got me frustrated is using it with .env files.

When attempting to run source .env in a project, I usually encounter this problem:

class TextToSpeech {
  constructor({ volume = 1, rate = 1, pitch = 1, lang = "en" } = {}) {
    if (typeof window === 'undefined' || !"speechSynthesis" in window) {
      throw new Error("Text to speech is not supported in your browser.");
    }

    this.engine = new SpeechSynthesisUtterance();
    this.setLanguage(lang)
      .setPitch(pitch)
      .setRate(rate)

const longEnough = (password, minLength = 12) => password.length >= minLength || warn(`Password should contain ${minLength} or more characters.`)
const hasUpperCase = password => /[A-Z]+/.test(password) || warn('Password should have at least one uppercase letter.')

// Solution
type Formatter<T> = (a: T) => (b: T) => string
const numberFormatter: Formatter<number> = decimals => euros => euros.toFixed(decimals).replace(/\./, ',') + ' €'
const toCurrencyString = numberFormatter(2)

// Tests
const suites: [number, string][] = [
    [-1, "-1,00 €"],
    [0, "0,00 €"],
    [1, "1,00 €"],
