Developing a preprocessor for Arduino

[Csányi Pál]

Hi,

I wish to develope a preprocessor for the Arduino programming language.
http://labs.arduino.org/Programming+Language

I wish to write this preprocessor in Emacs Lisp.
I imagine that that my pupils write the code in Emacs in their native
language.
So, eg. the Arduino command
setup() will be
beállít()
.

When they finished the program code, they run preprocessor.
The preprocessor should convert these commands in to English Arduino commands.

How should I start this project?

Best, Pali
