Compiler Code

A Python learning repository for compiler-design concepts, lexical analysis, parsing, translation, automata, and chapter-wise exercise solutions. The code is organized around classroom chapters, lab exams, and standalone compiler construction experiments.

Highlights

• Lexical analyzer that recognizes numbers, identifiers, keywords, and symbols.
• Recursive-descent parser for expression translation.
• Syntax tree, environment, tag, and token helper classes.
• Chapter-wise exercise solutions for compiler theory problems.
• Automata and lab-practice scripts for exams and finals.

Tech Stack

• Python

Getting Started

Run individual examples with Python:

cd chapter2
python lexer.py
python parser.py

Most scripts are standalone and print their output directly to the terminal.

Learning Goals

• Understand tokenization and symbol-table construction.
• Practice predictive parsing and infix-to-postfix translation.
• Implement automata and compiler-theory exercises in Python.
• Keep course and exam practice code organized by topic.
