Scrape ShaderToy. Instead of running this, consider downloading the files from here: https://goo.gl/MWGvkL Or if you want to do more work with ShaderToy data, consider using their API https://www.shadertoy.com/api

# The value of MAXN can be changed arbitrarily. When MAXN = 10**100, the

Distribute your Go program (or any single binary) as a native macOS application
// Package main is a sample macOS-app-bundling program to demonstrate how to
// automate the process described in this tutorial:
//
// https://medium.com/@mattholt/packaging-a-go-application-for-macos-f7084b00f6b5
//
// Bundling the .app is the first thing it does, and creating the DMG is the
// second. Making the DMG is optional, and is only done if you provide
// the template DMG file, which you have to create beforehand.
//
// Example use:

Simple Utility Script for allowing debug of hardened macOS apps.
#! /bin/bash
# Simple Utility Script for allowing debug of hardened macOS apps.
# This is useful mostly for plug-in developer that would like keep developing without turning SIP off.
# Credit for idea goes to (McMartin): https://forum.juce.com/t/apple-gatekeeper-notarised-distributables/29952/57?u=ttg
# Update 2022-03-10: Based on Fabian's feedback, add capability to inject DYLD for sanitizers.
#
# Please note:
# - Modern Logic (on M1s) uses `AUHostingService` which resides within the system thus not patchable and REQUIRES to turn-off SIP.
# - Some hosts uses separate plug-in scanning or sandboxing.
# if that's the case, it's required to patch those (if needed) and attach debugger to them instead.
