SHELL FUNCTIONS:

    Shell functions that can be added to `.bashrc` or `.bash_profle` for
    quickly generating QR codes from the command line. The command takes the
    argument as input or reads from stdin if none was supplied and outputs the
    QR code to stdout: `qrcode INPUT` or `echo INPUT | qrcode`

        qrcode () {
          local input="$*"
          [ -z "$input" ] && local input="@/dev/stdin"
          curl -d "$input" https://qrcode.show
        }

        qrsvg () {
          local input="$*"
          [ -z "$input" ] && local input="@/dev/stdin"
          curl -d "${input}" https://qrcode.show -H "Accept: image/svg+xml"
        }

        qrserve () {
          local port=${1:-8080}
          local dir=${2:-.}
          local ip="$(ifconfig | grep -Eo '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | fzf --prompt IP:)" \
            && echo http://$ip:$port | qrcode \
            && python -m http.server $port -b $ip -d $dir
        }
