Generate QR codes of Wi-Fi networks

Eventually, all dependencies should become optional

• the fish shell (will make a shell-agnostic binary later, in Go)

• ImageMagick (the display command)

• The qrcode command, install it like this:

  $ go install github.com/skip2/go-qrcode/qrcode@latest

• To leave out some arguments

  • NetworkManager as the system's network manager

  If you don't have this, you can still use wifiqr, but you'll have to provide all arguments (the name, password and "WPA" or "WEP")

0. Make sure your current shell is fish:

   $ echo $SHELL
   /usr/bin/fish

1. Install qrcode and put the qrwifi function in your fish config:

   $ go install github.com/skip2/go-qrcode/qrcode@latest
   $ git clone https://github.com/ewen-lbh/wifiqr
   $ cp wifiqr/wifiqr.fish ~/.config/fish/functions/
   $ rm -rf wifiqr

wifiqr [<name> [<password> [WPA|WEP]]]

Any unspecified argument will be auto-detected from /etc/NetworkManager/system-connections/<name>.nmconnection.

If <name> is not specified, it is assumed to be the currently in-use network (see nmcli dev wifi)
