Someone recently mentioned the “7 GUIs” task. I spent a couple of days to write up minimal solutions: 


In my spare time, I will develop this repo in more depth (types, units, etc) because it looks like a reasonably educational task.

Would it make sense to post the early ones to the 7GUIs site? They might be the easiest ones for others to understand.

FWIW I also came up with an even more interesting benchmark for GUIs, that I called "The Draggable Rectangle Challenge"

Here's one description


the solutions (in fairly portable Scheme, Racket-compatible) are described on the blog.

The code (presented by me on Racketfest) is also available in the repo (with the required modules for Racket):


(BTW slides for the Racketfest talk can be found here: https://github.com/panicz/writings/tree/master/talks/racketfest)

And one more thing,
someone provided a purely functional solution for the Draggable Rectangle Challenge in F# (I think it might be interesting to some).
The links can be found here:

I have continued my work on this repo, with two major additions:

— Macros/ which shows how to abstract over syntactic patterns in the GUI code
— Typed/ which injects types according to Typed Racket’s gradual typing philosophy

Both READMEs are simple experience reports. It has been fun, and I intend to add MVC implementations based on Units at some point soon, and perhaps a bit more.
