Args Module

The Args module provides access to command-line arguments passed to the program.

Functions

The Args object provides static methods for argument retrieval.

Args.count(): Integer

Returns the total number of command-line arguments, including the program name itself at index 0.

import std.io.*;

count: Integer = Args.count();
println("Received {count} arguments");

You can also import the function directly by symbol:

import std.args.count as count;

println("argc = {count()}");

That direct symbol alias can also be stored in a typed function value:

import std.args.get as get;

fetch: (Integer) -> String = get;

The direct stdlib member works as a typed function value too:

argc: () -> Integer = Args.count;

Args.get(index: Integer): String

Returns the argument at the specified index as a String.

  • Index 0 is always the path to the executable.
  • Indices 1 and above are user-provided arguments.
import std.io.*;

if (Args.count() > 1) {
    firstParam: String = Args.get(1);
    println("First argument: {firstParam}");
}
