booleancompliler

A small "compiler" for boolean expression for a tiny stack machine using a Recursive Descent Parser and the Visitor Pattern for the compiler

You can find a description of the project here

Instruction Set

This tiny VM as a small instruction set just to support a boolean expression.

• PUSH push a value onto the stack
• AND performs AND logic operation by popping two operands from the stack
• OR performs OR logic operation by popping two operands from the stack
• NOT performs NOT logic operation by popping one operand from the stack

The Virtual Machine handle 1 as true and 0 as false.

How to use

Clone the repository with:

git clone https://github.com/unnikked-ga/booleancompliler.git

Compile:

javac src/ga/unnikked.booleancompliler/*.java src/ga/unnikked/booleancompliler/*/*.java

And execute it with (remember to cd src):

java ga/unnikked/booleancompliler/Main

You can also pipe in a file using -f directive

cat yourfile | java ga/unnikked/booleancompliler/Main -f

Here an execution example:

$ cat test | java ga/unnikked/booleancompliler/Main -f
(true & ((true | false) & !(true & false)))
AST: (true & ((true | false) & !(true & false)))
CODE: [0, 1, 0, 1, 0, 0, 2, 0, 1, 0, 0, 1, 3, 1, 1]
RES: true
