CLP Project

Project for the AA 2023/2024 Complementi di programmazione's course of the Master Degree in Computer Science.

How to build

You first need to build the project using the Makefile.

make build

Run

You can run the software using the following command

java -cp lib/antlr-4.13.1-complete.jar:out Main <file.py>

you also can use three flags on the execution:

  • --optimize: runs the optimizer for the file <file.py>. The optimized version is auto saved at ./optimized.py.

  • --tree: shows the AST on video and on JFrame.

  • --exec: executes the SVM for the Assembly code generated in code.asm.

You can use all the three flags togheter if you want to.

Example

  • Optimizer
$ java -cp lib/antlr-4.13.1-complete.jar:out Main test/2a.py --optimize
n=int(input())
x=int(input())
m=1
tmp=2 * x
while n>1:

        m=m*tmp
        n=n-1


print(m+tmp)

Everything is OK!
