#+STARTUP: content 



* FxQrcode 

** Overview 



FxQrcode is a small and lightweight java desktop application to

transfer data through QRCode to any portable device with ability of

reading QRcode such as smartphones or tablets.



 - [[https://github.com/caiorss/fxqrcode][Project Repository]]



 - [[https://caiorss.github.io/fxqrcode][Project Website]]



It generates the QRCode from user input, for instance, if the user

type or paste the URL below, the app will generate a QRCode from

it. As the example shows, it is useful to transfer URL from a computer

to a smartphone or tablet.

** Download Binary Release 



 - Download: [[https://raw.githubusercontent.com/caiorss/fxqrcode/gh-pages/fxqrcode.jar][fxqrcode.jar]]



** Building instructions 



This application requires [[https://github.com/caiorss/jarget][jarget]] app and scala compiler as building

dependencies. 



The jarget app can be donwload with: 



#+BEGIN_SRC sh 

$ curl -o ~/bin/jarget -L https://github.com/caiorss/jarget/raw/v2.1.0-beta-release/jarget && chmod +x ~/bin/jarget 

#+END_SRC



Then to build run:



 - =$ make force && make guard=



#+BEGIN_SRC sh

  $ make force && make guard 

  jarget exec com.google.zxing/core/2.2,com.google.zxing/javase/2.2 -- scalac src/main.scala src/qrcode.scala -d bin/fxqrcode.jar
