swiftInterpreter

A swift interpreter written in python allowing swift code to be ran on any platform that supports python.

Running

Run the python swift interpreter with the following command

py swift.py [<*.swift file to be run>]

If no *.swift file is given, swift's REPL will start.

Project Organization

swift.py

The main script that either runs a .swift file or if none is given, starts a REPL session.

interpreter.py

Contains the class that parses swift code and runs code from swiftLang and stdlib

swiftLang

Contains the modules to support the base swift language.

All module names begin with lang_

Each module is named after the section it's found in in swift.org's Summary of Grammar.

For example, everything defined under GRAMMAR OF WHITESPACE should be defined in the file lang_whitespace.py

stdlib

Contains implementations in python of Apple's own stdlib

Internal folder structure matches Apple's.

Eventually the ability to read directly from the .swift files defined in Apple's own stdlib should be added as to not have to reinvent the wheel in python. May not happen for libraries that interface with things like stdout (Print.swift).

All module names begin with the parent folder's name followed by an underscore.

For example, the equivalent of Print.swift is named core_print.py
