Command Line Arguments

Overview

Command line arguments will be used with $$ as array.

• $$[0] is a script name.
• $$[n] is an nth argument if n >= 1.

Examples

Example 1. $$ used with each method

Code [args -> 1 2 3 4 5 6 7 8 end]

//
// Command Line Example:
//  $ ./kinx test.kx 1 2 3 4 5 6 7 8 end
//
$$.each(&(e, i) => System.println("Argument[%d] = " % i, e));

Result

Argument[0] = test.kx
Argument[1] = 1
Argument[2] = 2
Argument[3] = 3
Argument[4] = 4
Argument[5] = 5
Argument[6] = 6
Argument[7] = 7
Argument[8] = 8
Argument[9] = end

Example 2. Accessing $$ by index

Code [args -> 1 2 3 4 5 6 7 8 end]

//
// Command Line Example:
//  $ ./kinx test.kx 1 2 3 4 5 6 7 8 end
//
System.println("Argument length = ", $$.length());
for (var i = 0, len = $$.length(); i < len; ++i) {
    System.println("Argument[%{i}] = ", $$[i]);
}

Result

Argument length = 10
Argument[0] = test.kx
Argument[1] = 1
Argument[2] = 2
Argument[3] = 3
Argument[4] = 4
Argument[5] = 5
Argument[6] = 6
Argument[7] = 7
Argument[8] = 8
Argument[9] = end
