echo.png, in piet

This will echo whatever input string you give it, and exits when there is a '.'

I included a copy of the webpage that describes the language, as piet.html The only way I have been able to run Piet so far is in the browser, here

Make sure to load the small image, or the large one with a Codel width of 10.

Unlike my normal git workflow, I have decided to keep work in progress images separated so that people can quickly see how it was built up.

Notes: The program is greedy, and asks for all input in an infinite loop (which I accidentally made, its feature now!). So let's say I want it to exit when the stack is empty, how can I do that? Well, lets say it tries to chomp a '.', heres how I will check for a period and branch if its there:

dup # take the newest input 46 # push # push a '.' sub # subtract '.' from the newest input, push result on stack not # if result is anything but 0, push a 1, otherwise keep it as 0 pointer # rotate the direction pointer by 0 or 1

This is implemented in composition 03.
