Nemesis is a simplistic Forth single pass compiler written in OCaml using Menhir. As a compiler, it does not process immediate words, these are handled explicitly in OCaml code. This requires a slightly more complex grammar to prevent executing immediate words when they are defined.

Nemesis comes with an STC Forth for Cortex M0 chips, and a DTC Forth for MSP430 chips.

See nemesis --help on how to use the compiler. The compiler produces a raw binary file which can be flashed using e.g stm32flash for STM32 chips.
