Command line arguments in TXR can be treated as the lines of a text stream, which is arranged using the directive <code>@(next :args)</code>. Thus TXR's text parsing capabilities work over the argument list.
This <code>@(next :args)</code> should be written as the first line of the TXR program, because TXR otherwise interprets the first argument as the name of an input file to open.
<lang txr>@(next :args)
@(collect)
@arg
@(end)
@(output)
My args are: {@(rep)@arg, @(last)@arg@(end)}
@(end)</lang>
<pre>$ ./txr args.txr
My args are: {}
$ ./txr args.txr 1
My args are: {1}
$ ./txr args.txr 1 2 3
My args are: {1, 2, 3}</pre>
