-- This script uses Acorn (tested with version 6.6.4)
-- to add a light border around a window screenshot.
--
-- Screenshots (without the huge macOS shadows) are made by shift-cmd-4, then space bar,
-- then option-click on window (see https://apple.stackexchange.com/a/120017/17533)
--
-- Before use, you need to create a Preset Filter for this, once:
--   With an image opened, use from menu: Filter / Stylize / Drop Shadow…
--   Set its options as you prefer (e.g. X/Y offset 0, Blur Radius 2, Opacity 80%),
--   then save it by clicking the gear icon, choose "Save Filter Preset…" and

//	This code demonstrates a unicode normalization issue with reading file system paths on APFS
//	volumes in macOS.
//
//	TL;DR – In short, NSURL.path return paths (probably) always in NFD form even if the on-disk
//	        name is in NFC form, and even if you passed the on-disk path to NSURL to create it.
//	        Other path accessors, such as the canonical path, as well as BSD/POSIX functions
//	        will keep giving you the on-disk name.
//	        As a result, the name you get from NSURLNameKey may not be identical to the URL's

//  recycleURLs_crash_test
//
//  Created by Thomas Tempelmann on 01Feb21.
//
// Purpose:
//   Demonstrates that using [NSWorkspace recycleURLs:] on > 600 files often leads to a crash on macOS 10.12 and 10.13.
//   In my testing (on 10.13.6), up to 500 items never crash, while it starts crashing sometimes with 650 items
//   and nearly every time when it's over 800. I also get spurious errors on the first recycle interation when
//   using 600 items. This could be a precursor to the crash, but not sure.

# This script demonstrates an issue with SMB (and probably AFP as well)
# sharing, when accessing files by macOS that are hosted on a Linux share.
#
# Run this script on a Linux system to create two file in the current dir.
# Make sure it runs in bash, not sh, or the codes won't work.
#
# Make the generated files acessible via SMB, then try to access both files
# from macOS. The one called "decomposed_ü" won't be accessible - that's the bug.
