I have been casually writing a small program for nearly a year, a GUI-based
QR code generator imaginatively titled Qrgui. It is only a bash script less
than 120 lines long that passes arguments to qrencode, a commmand-line based
QR code generator, but it is a lot easier to use than qrencode itself.
I worked on it to gain experience running a small free software project, to
learn bash scripting, and to learn how to use git. It has helped me in all of
those things.
Thanks to all who gave me scripting pointers on early versions of the script
in this thread: https://trisquel.info/en/forum/front-end-qrencode
