Well, I found as much myself, tried all I could and it did not work. -----Original Message----- From: jtbr...@cpan.org [mailto:jtbr...@cpan.org] Sent: Thursday, January 12, 2012 9:53 AM To: recdescent@perl.org Subject: Re: How to build parser with autostubbing
Consult the section on '-s' at http://perldoc.perl.org/perlrun.html: -s enables rudimentary switch parsing for switches on the command line after the program name but before any filename arguments (or before an argument of --). Any switch found there is removed from @ARGV and sets the corresponding variable in the Perl program. The following program prints "1" if the program is invoked with a -xyz switch, and "abc" if it is invoked with -xyz=abc. #!/usr/bin/perl -s if ($xyz) { print "$xyz\n" } Do note that a switch like --help creates the variable ${-help} , which is not compliant with use strict "refs" . Also, when using this option on a script with warnings enabled you may get a lot of spurious "used only once" warnings. So this is probably what you want: perl -MParse::RecDescent -s -RD_AUTOSTUB - grammar NewMakepp::Grammar Untested, you may need to move -s, '-RD_AUTOSTUB and the '- grammar ...' arguments around to make it work.
