Falcon

=======

Falcon is a Python-like programming language compiler and transpiler.

The project contains:

- Regular expression based lexer

- Top-down recursive descent parser

- AST-walking codegen

- REPL 

- CPP transpiler

- CPP compilation and linkage (debug symbols included)

- Static typing (missing a type checker)

- Dinamic typing (using auto, not generics)

- Built-in stdlib (no imports for Built-in functions and symbols)

- Inline C++ 

Still missing:

- Type checking 

- Type based errors

- Include files (make proper use of include files)

- Inline assembly

Falcon doesn't require any third-party libraries.

What the language looks like:

.. code-block::

    func main() -> i32:

        let fp: file = open("./loops.flc", "r")

        let buffer: string = readfile(fp)

        print(buffer)

        closefile(fp)

        return 0

.. code-block::

    func dup(x: string, count: i32) -> string:

        let result: string = ""

        for i in 1 .. count:

            result = result + x

        return result

    func main() -> i32:

        println(dup("-", 50))

        for i in 1 .. 5:

            for j in 1 .. i:

                print("*")

            println("")

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

How to try it:

Requirements:

- Python 3.x.x

- GCC (with -std=c++20 support)

.. code-block::

    

    git clone https://github.com/vulture/falcon.git

    cd falcon

    make all tests

    ./test/array
