Leaf Compiler

A compiler for an object-oriented, dynamically typed, general-purpose programming language that supports mathematical algebraic expressions (graphing expressions, integrals, derivatives), written in C. Includes a Pratt operator-precedence parser, bytecode assembler, bytecode virtual machine, bytecode disassembler, and a read-eval-print-loop.

Example 'Leaf' code

var x = sin(3.14);
print x;

Output: 0

fun fib(n) {
	if(n < 2) return n;
	return fib(n-2) + fib(n-1);
}

print fib(30);

Output: 832040

Instructions to run

You can either use your own Makefile or the one already here in this repo to run the program using make -s. After you've done that, it'll output to a file called main, so you can run ./main to use the read-eval-print-loop (REPL) or ./main filename.lilac to run a file.

Licensing

This uses the MIT License and follows Robert Nystrom's Clox implementation from his book Crafting Interpreters. It's an amazing book that has taught me most of what I know about compilers today, and if you haven't read it I really recommend it!
