PyMonkey

Description

Python version of the Monkey programming language:

NOTE: This is a personal project created for the sole purpose of learning how to build interpreters / compilers and honing my Python skills. You may borrow code under the licence.

Dependencies

• Python 3.6+

Execution

Inside the src/monkey:

The Monkey interpreter plus macros can be run with:

python main.py

The compiler isn't complete yet but can be run with a flag --c:

python main.py --c

Ultimately, to compile a Monkey file, this command will be used instead:

python main.py [Program.mnk] [args]

Testing

Inside the test:

python [test_file].py

Progress

Interpreter

• Interpreter
• Built-in types and functions

Extras

• Macros

Compiler

• Compile expressions
• Conditionals
• Data structures
• Functions
• Closures

Possible Future extensions

• Better error handling (stack trace)
• More operators like postfix (e.g. ++, --) or ternary
• Default arguments to functions
• Macros hygiene
• Debugging Macros
• Continuations
• Time travel debugging
