Hello World

The current compiler samples usually use integer return values because the CLI can compile them into standalone executables without extra setup.

Int main() {
    print(42);
    print(false);
    return 42;
}

Compile and run:

./build/jiangc hello.jiang -o hello
./hello
echo $?

print is currently provided as a compiler-supported primitive. The runtime boundary still uses the host C runtime for low-level services such as printf, malloc, free, and abort.

A Small Function

Int add(Int a, Int b) {
    return a + b;
}

Int main() {
    return add(40, 2);
}

This is the smallest useful example for checking parsing, type checking, LLVM emission, and final linking.
