The point is to grok the entire system: Hardware, OS, compiler, interpreter...etc. I think building a FORTH would be educational, but I've never seen a tutorial (including JonesForth) that can take you from zero to Forth. Everyone just says it is easy. Maybe it is more or less obvious with more Assembly background? |

Skia used to include a really simple Forth implementation written in C++. According to https://groups.google.com/forum/#!topic/skia-discuss/joAyAl1... it was intended for straightforward/simple scripting, and for some reason promptly got deleted shortly after being brought up.
[In case you haven't noticed yet, the official Skia repo is at /google/; I've linked to /servo/'s obviously-old copy above, but there are more than enough forks and clones for the code to be findable elsewhere too.]
I kind of like this implementation because it's both incredibly context-specific and generalized all at the same time, and it isn't Bare Metal Implementation #79,513. And it's C++, too, although this is not (overly) abused.
