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
}

    Add Logo and Node.js example usage

    Hello, i create a new logo for this project, the combination of :

    • Greater than symbol ">" signifies terminal / curl
    • qrcode containing the qrcode.show url
    • qrcode.show with Munro Font

    and i add some example for Node.js using Got - Lightweight https library

    happy hacktoberfest!

  • CORS Missing Allow Origin

    CORS Missing Allow Origin

    Anyway you could allow any origin so that QR code could be generated client side in the browser? Access-Control-Allow-Origin: *

    I'm getting failed network requests when trying to do this in the browser. See example here: https://codesandbox.io/s/qrcode-test-gqktd?file=/src/App.vue

    Thanks!

    Add Node.js Usage Example

    Hi @sayanarijit Please kindly review my PR

    I added a usage example for the Node.js programming language, it's in the examples/nodejs folder with the README.md and index.js file in it

    Im using Got which is lightweight and well-known https request library for Node.js

    Hopefully it can be useful!

  • Adding quiet zone header to control the quiet zone

    Adding quiet zone header to control the quiet zone

    Hi @sayanarijit

    This adds a quiet zone header. The quiet zone is a padding that is added to the QR code to help avoid the scanner picking up it's surroundings. Ressource: https://delivr.com/faq/1455/whats-with-the-white-border-around-the-qr-code

    I have added the quiet zone function call to all formats. The default behaviour is false. My change will not interfere with the default behaviour that this library has. It will however give me the option to disable the quiet zone.

    Warning: I do not usually develop in Rust. Which means I probably hasn't done it the right way. You know the gist though. So maybe you can help ease out the kinks?

  • Add more web frontend functionalities

    Add more web frontend functionalities

    Is your feature request related to a problem? Please describe.

    We can pass many parametets from the command-line using http headers. But the web frontend is still lacking in functionalities. It can only generate SVG images and print the PDF, which is rather limited.

    Describe the solution you'd like

    Add a minimized "Advanced" button, clicking which we get more options. Options like download png/jpeg, set dimensions etc.

    Describe alternatives you've considered

    None

    Additional context

    The UI needs to be simple and easy to use. By default, users shouldn't be able to see all the buttons. Only by clicking the "Advanced" button, all the customisation options should appear. Also, we need to keep the website lightweight. Let's avoid using external libraries as much as possible.
