Chez-Forth

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

For those new to Forth:

• A "word" (a function) is defined like this:

: my_word 2 3 4 + + . ;

• Whenever my_word is 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!
