Nyx scripts can be run directly from the command line using a shebang line (#!/usr/bin/env nyx). The compiler's lexer recognizes #! at the start of a file and skips the entire line as a comment. get_args() provides access to command-line arguments.
#!/usr/bin/env nyx // Shebang scripts — running Nyx files as executable scripts // Scripts shebang — ejecutar archivos Nyx como scripts ejecutables // // Make this file executable: chmod +x 70-shebang-script.nx // Then run directly: ./70-shebang-script.nx fn greet(name: String) -> String { return "Hello, " + name + "!" } fn main() -> int { print(greet("World")) print("running as a script") let args: Array = get_args() print("args: " + int_to_string(args.length())) if args.length() > 1 { let name: String = args[1] print(greet(name)) } return 0 }
Hello, World! running as a script args: 1
How it works
A shebang line (#!/usr/bin/env nyx) at the top of a .nx file tells the OS to run it with the nyx command. The compiler's lexer recognizes #! at the start of a token and skips the entire line as a comment, so the shebang does not interfere with compilation.
get_args() returns the command-line arguments as an array of strings. The first element (args[0]) is the program name. Any additional arguments are accessible by index.
To make a script executable: create the file with the shebang line, run chmod +x script.nx, then execute it directly with ./script.nx. This makes Nyx suitable for shell scripting, build scripts, and quick utilities.
