## Introduction The panther language is a language made for exploitations. It's main focus is **minimal code size** through code size optimizations and compiling directly to a **shellcode** (position independent code). ## Flow 1. **Lexer**: Parse text file into tokens 2. **Parser**: Parse tokens into AST 3. **Analyzer**: Validate that the AST is correct panther syntax 4. **Bytecode**: Parse AST into bytecode 5. **LLVM**: Parse bytecode into LLVM IR 6. **Optimizations + Backend**: llvm ## What can it do currently? Currently, the panther binary can compile a single file using the llvm backend, with minimal type inference and type checking. When running the panther compiler on ``main.pan`` ```bash # Compile the panther compiler nimble build -d:release # Panther compiles an object file, in this example I compile to a windows COFF ./panther c -i main.pan -o output.o -t x86_***-pe-windows-coff # Link the object file to an executable, needed to get rid of relocations ld -nostartfiles output.o -o output.exe # Extract the .shell section created by the compiler objcopy -j .shell -O binary output.exe shellcode.bin ``` When ``main.pan`` looks like: ```rust proc _start(); // First function in the shellcode proc fib(a: s32) -> s32 { if a < 2 { return a; } else { return fib(a - 1) + fib(a - 2); } } // The printf symbol predetermined by an address. // In the future I would like to add a feature of searching for a symbol at runtime. let printf = 0x402ba0 as proc(fmt: string, num1: s32, num2: s32); proc _start() { let i = 1; while i <= 15 { printf("%d: %d\n", i, fib(i)); i = i + 1; } } ``` Results in a shellcode (``shellcode.bin``) that prints the the first 15 fibonnaci numbers.
