This project is a tiny compiler for a very simple language consisting of boolean expression.
The language has two constants: 1
for true and 0
for false, and 4 logic gates:
!
(not), &
(and), |
(or), and ^
(xor).
It can also use parentheses to manage priorities.
Here is its grammar in BNF format:
expr ::= "0" | "1"
