Every programming journey starts here. This is the smallest complete Nyx program: it defines a main function, calls print twice, and returns 0 to signal success. No imports, no boilerplate — just the code that matters.
// Programa mínimo: imprime un saludo al mundo fn main() -> int { print("Hello, world!") print("Bienvenido a Nyx") return 0 }
Hello, world! Bienvenido a Nyx
How it works
Every Nyx program starts execution from the main function. The return type -> int tells the compiler that main returns an integer — by convention, 0 means success and any other value signals an error to the operating system.
The built-in print function writes a string to standard output followed by a newline. It accepts a single String argument. Unlike many languages, Nyx does not require you to import anything to use print — it is always available.
Comments start with // and extend to the end of the line. They are ignored by the compiler and exist only for human readers.
