Pythonic.swift

Pythonic.swift is a Swift library implementating selected parts of Python's standard library and making them available to your Swift code.

import Pythonic allows you to write Python flavored code such as:

#!/usr/bin/env xcrun swift -i -I .

import Pythonic

if re.search("^foo", "foobar") {
  println(["foo", "bar", "zonk"].index("foo")) // 0
  println(["foo", "bar", "zonk"].count("bar")) // 1
  println(["foo", "bar", "zonk"].count("zoo")) // 0
}

if any(["foo", "bar", "zonk"]) {
  println(chr(ord("a"))) // a
}

var strings = ["foo", "bar"]
println(":".join(strings)) // foo:bar
if strings {
  println(strings[0]) // foo
}
if len(strings) == 2 {
  println(strings[1].upper()) // BAR
  println(strings[1].split("a")) // ["b", "r"]
}

var greeting = "   hello pythonista   "
if greeting.strip().startswith("hello") {
  println(greeting.strip().title()) // Hello Pythonista
}

var numbers = [1, 2, 3, 4, 5]
println(sum(numbers)) // 15
println(max(numbers)) // 5

Contributing

Code contributions are more than welcome! This is the quick guide to contributing:

1. Fork the project
2. Implement function foo from the Python standard library
3. Add a test case for foo in Pythonic-test.swift
4. Make sure the test case passes in both Python and Swift by running make test
5. Submit a pull request
6. Repeat until we're done :-)
