🛠 Compiler Design Toolkit

A multi-language educational toolkit demonstrating key concepts in compiler construction, including lexical analysis and symbol table management.
Implemented in Python, Ruby, and Java, this collection of small projects showcases the core building blocks of a compiler.

  • Java version (symbolTable.java)
  • Python version (symbol_table.py)
  • Stores identifiers, data types, and related metadata.

• Python Compiler Component

  • Prog1.py demonstrates a compiler-related process (see PDF for details).
