zadeviggers / embed-yotube-videos-in-md.ts
Last active June 22, 2022 23:56
A function to embed yotube videos in markdown
// This code looks for syntax like `{{youtube: https://www.youtube.com/watch?v=dQw4w9WgXcQ}}`
// rather than a plain URL, but it should be simple enough to modify the regex.
// Call this function on your raw markdown before your markdown processor (e.g. Marked, ReMark, etc) is run on it,
// and then pass the output of this function to your markdown processor.
function embedYoutubeVideos(md: string): string {
const ytRegexGlobal = /{{youtube: ?([^{}]+)}}/g;
const matches = md.matchAll(ytRegexGlobal);
let output = md;

The code for my search bar (https://publictransportforum.nz/articles). Made in SolidJS (with FuseJS for fuzzy matching) to be used in an Astro site. Note that this code is ripped straight from my source so it might need a bit of tweaking to make it work for you.
// Here are some snippets from the file that loads all my article's markdown files and does processing on them
// including generating the json file for search
import * as fs from "fs";
import path from "path";
const publicDirectory = path.join(process.cwd(), "public");
// At the bottom of the function that populates the cache of articles...
const searchFile = JSON.stringify(
articles.map((article) => ({

zadeviggers / url-parsing-regex.md
Created May 20, 2023 04:28

Parses any well-formed URI (and makes safe asumptions for commonly used bad formations), and outputs all the useful information in capture groups:

^(?:(.+?):\/\/)?(?:([^@/\n]+)@)?((?:[a-z]|[0-9]|\.)+)(?:\:([0-9]{1,5}))?([^#?\n]+)?(\?[^#\n]+)?(?:#(.+))?$
