This is a web-based interpreter for the second-order concatentive programming language Wagon.

Technically, it is Language.Wagon (the reference implementation of Wagon, written in Haskell) compiled to Javascript by the Haste compiler, running in an HTML5 document.


Select an example program from the dropdown box and click "Run" to run it. You can also edit the program before running it. Or you could clear the textbox and write an entirely new program there and run it.
