[![Build Status](https://travis-ci.org/thautwarm/reley.svg?branch=master)](https://travis-ci.org/thautwarm/reley)

See examples at `haskell_test/*.hs`.

Currently you can install reley compiler with `python setup.py install`.

Usage

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

- Compile:

```

> reley cc .hs -o .pyc

> python .pyc

```

- Run Reley

```

> reley run .hs

```

- Import reley programs in Python

If you have a reley source file `haskell_test/sum_n.hs`:

```haskell

module

    m_sum, (==) -- export `m_sum` and  `(==)`

where

import operator (add, eq)

import functools (reduce)

import toolz (curry)

import reley.prelude ((+))

infix 5 (==)

infix 0 ($)

(==) = curry eq

($) a b = a b

(+) = curry add

m_sum lst = if lst == [] then 0

            else destruct lst

            where

                destruct (a, b) = a + m_sum(b)

main () =

    print $ m_sum [1, 2, 3, 4, 5, 6]

```

Then you can import it in Python

```python

import reley.impl.pycompat

from haskell_test.sum_n import m_sum

lst = (5, (2, (1, ())))

print(m_sum(lst))

```

About Reley

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

It's in an early stage with many shortages.

Most of the crucial Haskell features are missing.
