Hiya, I was wondering, how i could get multiple occurences of a rule when using parse::RecDescent. For example, my code at the moment allows "print 'text'", but i need it so that it will allow this several times down the textarea and spot an error in any of the occurences. I have tried using /g, but am not sure how to use it properly. Any ideas? Cheers

my $mw = new MainWindow;
my $mw2 = $mw->Text()->pack();
my $mw3 = $mw->Button(-text=>"Check brackets",
                      -command => [ \&parser, $mw2 ]
                      )->pack();
MainLoop;

sub parser {
    my $txt = shift;
    my $grammar = q {
startrule: print open text end

print: "print"
open: "'"
text: /([^']*)/
end: "'"
};
    my $parser = Parse::RecDescent->new($grammar);
    if ( defined( $parser->startrule( $txt->get( "1.0", "end" )))) {
        print "NO ERROR\n";
    } else {
        print "TEXT COULD NOT BE PARSED\n";
    }
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
