PyRite

A lightweight interpreted scripting language with built-in arbitrary-precision arithmetic.

Features

• BigNumber — all numbers are arbitrary-precision by default
• C-like syntax — if/elif/else/end, while/end, fn/end
• OOP — classes (ins) and structs
• Modules — lazy-loading require with single-file and directory support
• Lambdas — fn(x) -> x * 2
• High-order functions, closures, try/catch, and more

Build

make release    # optimized build
make debug      # debug build with verbose output
make clean      # remove build artifacts

Requires a C++11 compiler (g++ or clang++).

Run

./PyRite script.pr        # run a file
./PyRite                  # start REPL

Example

fn fib(dec n) do
  if n <= 1 then return n endif
  return fib(n - 1) + fib(n - 2)
end

say(fib(20))  // 6765
