# PyTableaux | Tableaux solver with _Python_

Before anything else, set up your _**Python**_ environment (`venv`) with the follwing command in the current folder:

The first step is to install the version of _**Python**_ used in the project, which is contained in the file `.python-version`:

```bash
pyenv install
```

Now create the environment using this installed version:

```bash
pyenv virtualenv
pyenv activate
```

And install the dependencies:

```bash
pip install --require-virtualenv -r ./requirements.txt
```

To insert an input file, simpley enter the following in the terminal:

```bash
python main.py < ./inputs/.tab
```

For example, let's insert to first test file:

```bash
python main.py < ./inputs/example.tab
```

This example file will generate the following output:

```bash
satisfiable
```

Now, let's test a file that admits an **UNSAT** formula:

```
python main.py < ./inputs/example2.tab
```

Generating the following output:

```bash
unsatisfiable
Tp Fq
```
