I feel like I'm slowly becoming a Nix shill, but... Nix is a good alternative as well.

Install Nix in one command:

    sh <(curl -L https://nixos.org/nix/install) --no-daemon

Then run Magic Wormhole in one command, without even having to install it:

    nix-shell -p magic-wormhole --run 'wormhole send myfile'

I've been trying out Nix lately and did something similar to get a croc binary. My system package manager didn't have croc and also didn't have the Go version required to compile croc, but Nix did have the latest Go.

Ran this:

  nix-shell -p go --run "go install github.com/schollz/croc/v9@latest"

and got it compiled. In retrospect, I should have just used the croc package in Nix, but the simplicity of this approach is a vast improvement over the alternative of getting Go myself and cluttering up my system with random build tools for one-off compilations.

The go version has a really cool feature: wormhole-william send --qr <path/to/file>

This prints the password as a QR code. There's also an android version of wormhole-william which can process the QR codes.
