FFmpeg cheat sheet

git clone and cd function

A simple little alias function that lets you clone and cd into a GitHub repo in one command.

Installation

Add to your zsh or bash config (usually ~/.bash_profile or ~/.zshrc) and open a new terminal to be able to use the function.

Usage

gcd [github_repo_owner/repo_name]
javascript:(function()%7Bconsole.log(%0A%20%20Array.from(document.querySelectorAll('h1%2C%20h2%2C%20h3%2C%20h4%2C%20h5%2C%20h6')).reduce((str%2C%20heading%2C%20index%2C%20arr)%20%3D%3E%20%7B%0A%20%20%20%20const%20level%20%3D%20Number(heading.tagName.slice(1))%3B%0A%0A%20%20%20%20if%20(level%20%3D%3D%3D%201%20%26%26%20heading.textContent%20%3D%3D%3D%20'No%20Preview')%20%7B%0A%20%20%20%20%20%20return%20str%3B%0A%20%20%20%20%7D%0A%0A%20%20%20%20const%20style%20%3D%20getComputedStyle(heading)%3B%0A%20%20%20%20const%20previousLevel%20%3D%20index%20%3D%3D%3D%200%20%3F%20level%20%3A%20Number(arr%5Bindex%20-%201%5D.tagName.slice(1))%3B%0A%20%20%20%20const%20indentation%20%3D%20(level%20-%20previousLevel%20%3E%201%20%3F%20'*'%20%3A%20'-').repeat(level)%3B%0A%20%20%20%20const%20isAriaHidden%20%3D%20heading.getAttribute('aria-hidden')%20%3D%3D%3D%20'true'%3B%0A%20%20%20%20const%20isDisplayNone%20%3D%20style.display%20%3D%3D%3D%20'none'%3B%0A%20%20%20%20const%20isVisibilityHidden%20%3D%20style.visibility%20%3D%3D%3D%20'h

Ever noticed how vw/vh units in CSS seem to be a bit unreliable on various devices (especially mobile)? Here's my solution.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">
<title>Test Page</title>
<script>
// early compute the vw/vh units more reliably than CSS does itself
computeViewportDimensions();
