Minsk Compiler This project is a simple compiler written in C#. It includes a lexer, parser, syntax tree, and an evaluator for basic arithmetic expressions.

Features Lexical analysis Parsing Syntax tree generation Expression evaluation Parse tree visualization Supported Expressions The compiler currently supports basic arithmetic expressions involving:

Addition (+) Subtraction (-) Multiplication (*) Division (/) Parentheses for grouping (()) Usage Running the Compiler Clone the repository. Open the solution in Visual Studio or any other C# IDE. Build and run the project. Interactive Mode The compiler runs in an interactive mode. After running the program, you can type in arithmetic expressions to be evaluated.

Commands #showTree: Toggle the display of the parse tree. #cls: Clear the console. Example markdown Copy code

#showTree Showing parse trees.

PrettyPrint The PrettyPrint method recursively prints the syntax tree for visualization.

Lexer The Lexer class is responsible for breaking the input text into a sequence of tokens.

Parser The Parser class processes the tokens produced by the lexer and constructs a syntax tree.

Syntax Tree The syntax tree is represented by various classes inheriting from SyntaxNode, including:

SyntaxToken ExpressionSyntax NumberExpressionSyntax BinaryExpressionSyntax ParenthesizedExpressionSyntax Evaluator The Evaluator class walks the syntax tree and computes the value of the expression.

Future Improvements Support for more complex expressions and additional operators. Improved error handling and diagnostics. Optimization passes on the syntax tree. Additional features such as variable assignments and functions. Contributing Contributions are welcome! Please fork the repository and submit pull requests.
