Abrvalg

=======

Abrvalg is a Python-like programming language interpreter.

The project contains:

- Regular expression based lexer

- Top-down recursive descent parser

- AST-walking interpreter

- REPL

Abrvalg doesn't require any third-party libraries.

What the language looks like:

.. code-block::

    func map(arr, fn):

        r = []

        for val in arr:

            r = r + [fn(val)]

        r

    func factorial(n):

        if n <= 1:

            1

        else:

            n * factorial(n - 1)

    print(map(1...10, factorial))

You can find more examples in ``tests`` directory.

How to try it:

.. code-block::

    

    git clone https://github.com/akrylysov/abrvalg.git

    cd abrvalg

    python -m abrvalg tests/factorial.abr
