enpy

English syntax for Python

Programming enpy

is the same as writing in english. The following English (examples/input2.en):

Compose a function named *firstprime* whose definition is as follows:
Provided a starting number: *firstprime* will

    Compose a closure named *inner*:
    Which takes a number, and some potential divisor:

        when the number % the divisor is 0, return the divisor;
        otherwise, return the inner of the (number, and the divisor+1)

    return the result of inner of the (number, and 2)

Test: print the firstprime of (43);assert that the firstprime of (43) is 43;assert the firstprime of (93) is 3

generates the following Python:

#!/usr/bin/env python
#-*- coding: utf-8 -*-

    input2.py

def firstprime(number):
   def inner(number, divisor):
       if number % divisor == 0:
           return divisor;
       return inner(number, divisor+1)
   return inner(number, 2)

if __name__ == '__main__':
     print firstprime(43);assert firstprime(43) == 43;assert firstprime(93) == 3

and (in the next version) will run the generated code.
