Implement an evaluator for a very simple subset of Forth.
Forth is a stack-based programming language. Implement a very basic evaluator for a small subset of Forth.
Your evaluator has to support the following words:
+,-,*,/(integer arithmetic)DUP,DROP,SWAP,OVER(stack manipulation)
Your evaluator also has to support defining new words using the customary syntax: : word-name definition ;.
To keep things simple the only data type you need to support is signed integers of at least 16 bits size.
The evaluator must also be available via a web interface served by Phoenix Liveview. The user interface features must include:
- uploading a forth program
- requesting an evaluation
- showing the results
- a history of evaluated programs
