Port of Total Spectrum's tinyscript to the Arduino platform
Copy the repo to your libraries folder, the try out the REPL sketch. It's a pretty basic C like language. See https://github.com/totalspectrum/tinyscript for documentation.
This is all experimental and subject to change.
In this fork, numbers are 64 bit signed ints. You'll get error -6 if a command tries to run for more that 250k instructions.
All of those directly mirror the standard Arduino equivalents
