A Forth interpreter written in Chez Scheme
- You can install Chez Scheme via brew like this:
$ brew install chezscheme- And invoke it like this:
$ chez --script __filename__- Given that a word is not found in the dictionary,
- Or if a symbol is considered invalid, an error is reported
- A "word" (a function) is defined like this:
: my_word 2 3 4 + + . ;- Whenever
my_wordis used, 2, 3, and 4 are pushed onto the stack, addition is applied twice, and the result is popped off and printed to stdout. - All actions in forth are based on calling words, or just pushing and popping elements from the stack. You should get the hang of it pretty quickly!
