This project implements a Mini Pascal Interpreter, capable of parsing, analyzing, and interpreting a subset of the Pascal programming language. This code is an expanded version of the interpreter described in Ruslan Spivak's "Let's Build A Simple Interpreter" series.
- Lexical analysis
- Syntax parsing
- Semantic analysis
- Interpretation of Pascal programs
- Support for basic Pascal constructs including:
- Variables and data types
- Arithmetic operations
- Control structures (if-else, while)
- Procedures
- Input/Output operations
The main components of the interpreter are:
- Lexer: Tokenizes the input
- Parser: Builds an Abstract Syntax Tree (AST)
- Semantic Analyzer: Performs semantic checks
- Interpreter: Executes the Pascal program
- Python 3.6+
- Clone the repository:
git clone https://github.com/yourusername/mini-pascal-interpreter.git
cd mini-pascal-interpreter
- No additional dependencies are required as the project uses Python standard libraries.
Run the interpreter with a Pascal source file:
python interpreter.py your_pascal_file.pas
--scope: Print scope information--stack: Print call stack--lexer: Print lexer tokens--visitor: Print visitor information--mips: Print MIPS-related information
Example files are included in the repo.
