cpplax

The C++ implementation for the language Lax which is a dynamically typed language that is similar to JavaScript.

Getting Started

Build and Run

Please make sure CMake (at least version 3.20) is well installed on your OS.

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build ./build

Test

Run the below commands after the previous step. By default, the test will be running via the compiler and VM, in order to test the interpreter, please re-run the preceding CMake setup command and specify the environment variable TEST_TARGET=INTERPRETER.

ctest --test-dir ./build

Running Lax Code

Step 1: save the below code into a text file named "fib.lax".

// fib.lax
fn fib(n) {
  if (n <= 1) return n;
  return fib(n - 2) + fib(n - 1);
}
print(fib(30));  // "832040".

Step 2: invoke the compiler and virtual machine via the below command:

./build/bin/cpplax fib.lax
