pyrsmk / busy.ts
Created July 1, 2022 14:06
A simple function that marks a callback as busy to avoid calling it multiple times before it has finished its task.
const busyCallbacks = new Set()
export async function busy(callback : () => any) : Promise<any> {
if (busyCallbacks.has(callback)) {
return
}
busyCallbacks.add(callback)
const value = await callback()
busyCallbacks.delete(callback)

Convert XML files to JS objects.

pyrsmk / async_queue.ts
Last active July 8, 2022 08:53
A queue that handles async functions in order with a wait time between each callback.
/*
Usage:
import async_queue from 'async_queue'
const queue = async_queue(<wait_time_in_ms>)
queue(async () => await someSlowAction1())
queue(async () => await someSlowAction2())

Last active January 4, 2022 14:08
// Currently, the ESLint plugin used by Svelte is buggy and choke on files with Sass.
// This little implementation takes care of removing styling from Svelte components as
// as well as handle any type of files other than Svelte, with complete respect of rules
// from the base ESLint plugin (that is, `.eslintrc.cjs` rules are used). It has been
// thought to be simple to use and integrate.
