Demo page for a forth interpreter cross compiled from C using emscripten. Read the README in the github repository for more details. github.com/marianoguerra/ricardo-forth/
To run first append some input by writing in the input text area and clicking append input, successive clicks will append to the input buffer that simulates stdin, then click run.
Once it runs to completion the binary calls exit(0), normally you would run it again, here you have to reload the page :)
