I have made a quick VSCODE-Portable installer just execute the script inside a macOS empty folder to have a working copy of visual studio code portable that is self contained inside that folder (not messing with your main VSCode profile easy to throw away or to keep on a USB stick)
Run this script in an empty folder to install Luxcium's Vscode Portable:
bash <(curl -s https://gist.githubusercontent.com/Luxcium/7357d34622c148f6041842321f315d7a/raw/a758b82e6818b9b9b664b210228ea93f9314c1b4/luxcium-vscode-portable.sh)
