rust-jcs-transpiler

A transpiler written in rust, which translates C# code into Java code.

How to use

• Place your C# code inside input.cs
• Run the program using

  cargo run
  

• The resulting code can be found inside output.java

Features

• Parses C# classes and methods
• Detects C# Main() and converts it into a Java main(String[] args) function
• Supports variable declaration
• Supports assignments and expressions, including
  • Binary expressions
  • Unary expressions
• Parses if-else statements
• Parses for loops and while-loops
• Handles function calls
• Handles user output and input
  • Console.WriteLine -> System.out.println
  • Console.ReadLine -> Scanner type input
  • int.Parse, double.Parse, bool.Parse -> scanner.nextInt(), etc
• Supports nested function calls, such as int.Parse(Console.ReadLine())
• Automatically declares a Java Scanner when user input is needed

Limitations

• Does not support switch, try-catch and other advanced features
• Does not support arrays
• Only handles predefined types (int, bool, float, double, string)
• Invalid or unsupported C# syntax may cause the program to panic
