Simple Compiler

A basic compiler implementation in Python that handles arithmetic operations, variables, and if-else statements.

Features

• Lexical analysis
• Syntax parsing
• Semantic analysis
• Intermediate code generation
• Support for:
  • Arithmetic operations (+, -, *, /)
  • Variable assignments
  • If-else statements
  • Comparison operators (==, >, <)

Usage

1. Create an input file (e.g., input.txt) with your source code
2. Run the compiler:

   python main.py input.txt
   

Example Input

x = 10
y = 5
if x > y {
    result = x - y
}   
else {
    result = y - x
}

Example Output

Generated Intermediate Code:
x = 10
y = 5
t1 = x > y
if not (t1):
    goto L2
t4 = x - y
result = t4
# goto L3
# L2:
t5 = y - x
result = t5
# L3:

Requirements

• Python 3.7 or higher
