Features

• Lexical Analysis: Identifies keywords, identifiers, constants, and various operators.
• Syntax Analysis: Validates the structure of the program.
• Visual Feedback: Displays the analysis results in list boxes with color-coded highlighting.
• Error Detection: Highlights syntax errors with line and character position details.
• Interactive UI: Simple Windows Forms interface for input and output.

Setup

1. Clone the repository:

   git clone https://github.com/tanvir-ahamed04/csharp-compiler.git

2. Open the solution in Visual Studio.

3. Restore the NuGet packages if any.

4. Build the solution to resolve dependencies.

Usage

1. Run the application in Visual Studio.

2. Input your program code in the provided text box.

3. Click the buttons to perform lexical and syntax analysis:

   • Lexical Analysis: Click the Analyze Lexically button.
   • Syntax Analysis: Click the Analyze Syntax button.

4. The results will be displayed in the list boxes:

   • The first list box will show the lexical analysis results.
   • The second list box will show any syntax errors and the syntax analysis results.

Code Structure

• Form1.cs: Main form containing the logic for lexical and syntax analysis.

  • Properties:

    • input_program: Stores the input program code.
    • input_pointer, num, text, line_number, char_position: Various pointers and counters for analysis.
    • identable, constable: Instances of Identable and Constable classes to store identifiers and constants.
    • presentInput: Stores the current input token.

  • Methods:

    • button1_Click: Handles lexical analysis when the button is clicked.
    • button2_Click: Handles syntax analysis when the button is clicked.
    • print, output: Helper methods to print messages in the list boxes.
    • nextInput: Retrieves the next token from the input program.
    • match, ParseProgram, parseIdentifierList, etc.: Methods for syntax analysis.

• Identable.cs: Class to handle identifiers.

  • clear, addidentifier, dump: Methods to manage identifiers.

• Constable.cs: Class to handle constants.

  • clear, add, dump: Methods to manage constants.
