Peryton
A Python to Swift Transpiler
Peryton, named after the mythological deer that has the wings of a bird, is a Python to Swift Transpiler. It can accept native Python code, parse it, and translate that code to the equivalent code in swift. The major advantages of using Peryton are:
- You can write IOS/OS X applications use Python.
- You can make use of the Swift language without having to learn it's syntax, rules etc.
- You can convert your favorite Python modules/documents to Swift code to use in your IOS/ OS X applications.
Compatability
Transpiling Python to Swift does raise a number of issues in the process. The first and foremost one, is the lack of type safe practices in Python, where you do not specify the type being passed into a function and the type being returned. Fortunately, Peryton handles this issue by type-testing the input of functions, as well as object attributes.
In Swift, you can declare variables and constants:
var t = 0
let thing = "Hello"
Where changing the let constant causes an error. Python does not have constants. However, one can theoretically infer from the structure of a function or program if a variable has the need for being protected. Peryton will be developed to do this through a process called Flow_Analysis, that determines the connections between functions, classes, objects and other parts of a program.
Equivalency
In Swift, there are times when using a specific element of the language is more efficient than it's equivalent element in Python. As a basic example:
class frogs(object):
fly_count = 7
length = "four"
-
Since this class only contains a set of variables, it would be better suited as a struct, not a class. Peryton will be developed to tell that difference in the process of writing Swift code.
