## Installation

CubeLang requires Python 3.6 or newer to functions. For the information on how to install Python, please refer to the [download page](https://www.python.org/downloads/).

The easiest way to install CubeLang is by using pip. On how to install pip please refer to the [manual](https://pip.pypa.io/en/stable/installing/).

```bash
pip install CubeLang
```

After the installation, `cubelang` and `cubelang-scramble` command-line utilities will be available.

#### Development

For the development of CubeLang clone this repository and install dependencies.

```bash
git clone https://github.com/poletaevvlad/CubeLang.git
cd CubeLang
pip install lark-parser termcolor
pip install -r test_requirements.txt
```

Tests for the interpreter are located in the `test` directory, tests for the example programs are in the `test_examples` directory. CubeLang uses pytest for testing.

## Examples

There are two example programs written in CubeLang. They are located in the `examples` directory of the GitHub repository.

The results of executing example programs are shown below.
