Parse command-line arguments: Difference between revisions

=={{header|Wren}}==

Any command line arguments passed to a Wren CLI script are collected in the same order into a list of strings. If individual arguments require any further parsing, this can then be done using normal Wren code.

<lang ecmascript>import "os" for Process

var args = Process.arguments

System.print("The arguments passed are: %(args)")

// parse last argument to a Range object

var sp = args[-1].split("-")

var start = Num.fromString(sp[0])

var end = Num.fromString(sp[1])

var r = start..end

System.print("The final argument expressed as a Range object is %(r)")</lang>

{{out}}

<pre>

$ wren_cli parse_command-line_arguments.wren -v -n -z -w 1 192.168.1.2 1-1000

The arguments passed are: [-v, -n, -z, -w, 1, 192.168.1.2, 1-1000]

The final argument expressed as a Range object is 1..1000
