Created October 6, 2022 08:19

document.querySelectorAll('button[aria-label="Toggle diff contents"]').forEach(b => b.click())

Generate Blob import from file on disk with deno

	const bytes = await Deno.readFile(new URL('./thumbnail.png', import.meta.url))

	const contents = encoder.encode(
	`export const thumbnail = new Blob(new Uint8Array(${
	JSON.stringify(Array.from(bytes))

	)

	await Deno.writeFile(new URL('./hardcoded-thumbnail.ts', import.meta.url), contents)

myobie / async_iterators_throw_catch_test.ts

Last active February 10, 2022 11:40

I was testing to see if the next() in an async iterator worked how I suspected, where throws are really Promise.reject() which throws at the for await point.

	import { assertEquals } from 'https://deno.land/std@0.125.0/testing/asserts.ts'

	Deno.test('async iterator throw in next should throw in for scope', async () => {
	const results: number[] = []

	const numbers = (() => {
	let counter = 0

	const iterator: AsyncIterator<number> = {
	// deno-lint-ignore require-await

myobie / deferred.ts

Created August 2, 2021 15:09

My own promise-like object where I can type the rejection and I can resolve from the outside

	export class Deferred<T = void, E = Error> {
	#promise: Promise<T>
	// deno-lint-ignore ban-ts-comment
	// @ts-ignore
	resolve: (arg: T) => void
	// deno-lint-ignore ban-ts-comment
	// @ts-ignore
	reject: (arg: E) => void

	constructor() {

myobie / task.ts

Created July 30, 2021 10:10

Very simple deno script to test that deno works

	console.log('Fetching...')
	const res = await fetch('https://example.com')
	const body = new Uint8Array(await res.arrayBuffer())
	console.log('---')
	await Deno.stdout.write(body)
	console.log('---')
	console.log('Done.')

myobie / server.ts

Created July 29, 2021 18:25

Very simple deno webserver mostly exactly from the example in the docs at https://deno.land/manual/examples/http_server

	// Start listening on port 8080 of localhost.
	const server = Deno.listen({ port: 8080 })
	console.log('HTTP webserver running...')

	const headers = Object.freeze({
	'Content-type': 'plain/text'
	})

	for await (const conn of server) {
	// deno-lint-ignore no-extra-semi

I'm not saying this is a good idea, but I'm not not saying it

	defmodule POC.Params do
	import Ecto.Changeset

	@spec permit(map, map) :: map
	def permit(input, types) do
	{types, nested} = Enum.reduce(types, {%{}, %{}}, &process_types/2)
