PlayWithCompiler offers practical code examples corresponding to GeekTime's "The Beauty of Compiler Construction" course. It allows users to actively engage with compiler design by implementing various components like lexers, parsers, and interpreters. The project primarily utilizes Java and leverages ANTLR for grammar and lexer generation.
The repository features a range of implementations, from a simple calculator to a script interpreter and a regex tool. It effectively integrates ANTLR for parsing, demonstrating how to automate grammar processing. Key components like parser generators and finite automata are thoroughly addressed.
- Lexer Implementation: Provides simple and ANTLR-based lexer examples for tokenizing input.
- Parser Implementation: Includes examples for building both recursive descent and ANTLR-based parsers.
- Script Interpreter: Offers a basic REPL-style interpreter for a custom scripting language.
- Regex Tool: Implements tools for generating NFA and DFA from regular expressions and performing string matching.
- ANTLR Integration: Demonstrates the use of ANTLR for lexer and parser generation from grammar files.
- Finite Automata: Contains implementations of finite automata and their states for lexical analysis.
- EBNF Representation: Uses GrammarNode to represent lexical and grammatical rules.
The project is actively maintained with recent commits and ongoing updates to documentation and code. It serves as a valuable resource for learning and experimenting with compiler construction techniques, with a focus on practical implementation. The accompanying materials are continuously evolving alongside the course content.
This project benefits students and developers seeking hands-on experience with compiler construction. It offers a practical approach to understanding compiler design principles and implementing core components. It's particularly useful for those wanting to learn how to use ANTLR for building parsers and lexers or to implement small scripting languages.
