A library and command-line tool for working with Boolean expressions

## Synopsis

tt is a Python library and command-line tool for working with Boolean expressions. Please check out the project site for more information.

## Installation

tt is tested on CPython 2.7, 3.3, 3.4, 3.5, and 3.6. You can get the latest release from PyPI with:

```pip install ttable
```

## Basic Usage

tt aims to provide a Pythonic interface for working with Boolean expressions. Here are some simple examples from the REPL:

```>>> from tt import BooleanExpression, TruthTable
>>> b = BooleanExpression('A xor (B and 1)')
>>> b.tokens
['A', 'xor', '(', 'B', 'and', '1', ')']
>>> b.symbols
['A', 'B']
>>> print(b.tree)
xor
`----A
`----and
`----B
`----1
>>> b.evaluate(A=True, B=False)
True
>>> t = TruthTable(b)
>>> print(t)
+---+---+---+
| A | B |   |
+---+---+---+
| 0 | 0 | 0 |
+---+---+---+
| 0 | 1 | 1 |
+---+---+---+
| 1 | 0 | 1 |
+---+---+---+
| 1 | 1 | 0 |
+---+---+---+
>>> t = TruthTable(from_values='01xx')
>>> t.ordering
['A', 'B']
>>> for inputs, result in t:
...     inputs, result
...
(<BooleanValues [A=0, B=0]>, False)
(<BooleanValues [A=0, B=1]>, True)
(<BooleanValues [A=1, B=0]>, 'x')
(<BooleanValues [A=1, B=1]>, 'x')
>>> t.equivalent_to(b)
True
```
