9e9573b3dd Fairly complete rewrite of VM. Now supports composite words with { w1 w2...}. Rewrote :, if, ifelse and while to use composite words. Namespaces now have Clojure like vars for indirection and also support inline words. Words defined in Python now use Python function decorators to add Sallyforth related metadata. 2020-05-09 10:47:47 -04:00

Russ Olsen
502f120d7b Added builtin alias word, which means we can define most of the built-in words with non-Python comparible names (think . and +) in sallyforth instead of Python. Also added backslash comments and stack reset work. 2020-04-18 12:12:10 -04:00

97c3aa1fff Switched the word function xface so that words now return the new ip instead of a delta. This simplifies the interpreter allows recur to simply return 0. Also changed the tokenizer so that 'foo produces a string w/o the need for a closing quote, good for symbols. 2020-04-18 10:22:25 -04:00
