Reducing the footprint of AVR-Nano
AVR-Nano leaves 1% program memory space :-( I understand it's a tight squeeze but am wondering what items could be jettisoned to make it a bit tighter to allow for other code to be there, and for Lisp code to be stored in PROGMEM. One obvious target would be the REPL and the Serial library...
@eclab I'm currently working on a project for a client that I'm running on a hybrid of ulisp and cpp, and also needed some more flash space.
I've found a really nice way to do this is simply to comment out ulisp fn's I wouldn't be using out of the symbol table. The linker takes care of the rest during compilation.
Platformio has a nice tool that lets you see what is taking up flash and sort by size, so I used that to quickly make some large gains. fn_format off the top of my head was the biggest one, but there are several high yield ones in there.
