Yeah, very cool. I was thinking about possibly porting it to risc-v and using it on my fpga based core. I was trying to build a monitor style shell, but C like environment would be very cool.

Porting to different CPU/bytecodes should be doable. Just keep in mind that in ESP-IDF we also get the dynamic linker and the libc for free (and any other C functions exposed in the firmware). On the other platforms, that may be some extra work for the compiler.
