-------------

An implementation of `Arrow `_ in Python.

Running Arrow code

==================

.. code-block:: text

    $ arrow --help

    usage: arrow [-h] [file]

    positional arguments:

      file        A file to run. Use - for stdin without prompt.

    optional arguments:

      -h, --help  show this help message and exit

Example Arrow program

=====================

.. code-block:: text

    function

    /--> int factorial(int n)

    | require not (n < 0)

    | int return

    | /--< n != 0

    | | return = 1

    | \-->

    | /--< n == 0

    | | return = n * factorial(n - 1)

    | \-->

    ^ return

    main

    int n

    print "Enter number:"

    n = input int

    print "Factorial of", n, "is", factorial(n)

Which outputs:

.. code-block:: text

    Enter number:

    5

    Factorial of 5 is 120
