📌 Example Usage

boolean-table expression "(a -> ~b) == (b | a)"

# Truth table for (a -> ~b) == (b | a)
| a | b | (a -> ~b) == (b | a) |
|---|---|----------------------|
| 0 | 0 | 0                    |
| 0 | 1 | 1                    |
| 1 | 0 | 1                    |
| 1 | 1 | 0                    |

Or by printing subexpressions:

boolean-table expression "(a -> ~b) == (b | a)" --step

# Truth table for (a -> ~b) == (b | a) by printing subexpressions
 | a    | b    | ~b    | (a -> ~b) | (b | a) | (a -> ~b) == (b | a) |
 |------|------|-------|-----------|---------|----------------------|
