Project Description

truths is a simple tool that allows you to quickly generate a truth table from python variable names and phrases

install

pip install truths or git clone and pip install -e to play with the code

use is simple:

start by creating some base variables

import truths
print truths.Truths(['a', 'b', 'x'])
+---+---+---+
| a | b | x |
+---+---+---+
| 0 | 0 | 0 |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
| 1 | 1 | 1 |
+---+---+---+

add some phrases

now let’s use those base variables and pass in some phrases! your base variables can be anything you want but must be valid python variable names. the phrases also have to be valid python

from truths import Truths
print Truths(['a', 'b', 'cat', 'has_address'], ['(a and b)', 'a and b or cat', 'a and (b or cat) or has_address'])
+---+---+-----+-------------+-----------+----------------+---------------------------------+
| a | b | cat | has_address | (a and b) | a and b or cat | a and (b or cat) or has_address |
+---+---+-----+-------------+-----------+----------------+---------------------------------+
| 0 | 0 |  0  |      0      |     0     |       0        |                0                |
| 0 | 0 |  0  |      1      |     0     |       0        |                1                |
| 0 | 0 |  1  |      0      |     0     |       1        |                0                |
| 0 | 0 |  1  |      1      |     0     |       1        |                1                |

| 0 | 1 |  0  |      1      |     0     |       0        |                1                |

prefer boolean words?

neat eh? if you prefer True/False over the numbers pass ints=False:

from truths import Truths
print Truths(['a', 'b', 'x', 'd'], ['(a and b)', 'a and b or x', 'a and (b or x) or d'], ints=False)
+-------+-------+-------+-------+-----------+--------------+---------------------+
|   a   |   b   |   x   |   d   | (a and b) | a and b or x | a and (b or x) or d |
+-------+-------+-------+-------+-----------+--------------+---------------------+
| False | False | False | False |   False   |    False     |        False        |
| False | False | False |  True |   False   |    False     |         True        |
| False | False |  True | False |   False   |     True     |        False        |
| False | False |  True |  True |   False   |     True     |         True        |
| False |  True | False | False |   False   |    False     |        False        |
| False |  True | False |  True |   False   |    False     |         True        |
| False |  True |  True | False |   False   |     True     |        False        |
| False |  True |  True |  True |   False   |     True     |         True        |
|  True | False | False | False |   False   |    False     |        False        |
|  True | False | False |  True |   False   |    False     |         True        |
|  True | False |  True | False |   False   |     True     |         True        |
|  True | False |  True |  True |   False   |     True     |         True        |
|  True |  True | False | False |    True   |     True     |         True        |
|  True |  True | False |  True |    True   |     True     |         True        |
|  True |  True |  True | False |    True   |     True     |         True        |
|  True |  True |  True |  True |    True   |     True     |         True        |
+-------+-------+-------+-------+-----------+--------------+---------------------+

how it works

check out the code! behind the scenes it’s putting the bases in an object context and generating a grid of values for them. then, the phrases are evaluated in the object’s context against each row in that grid of values
