( #3333=superdoc: print w/replies, xml ) Need Help??

Hi friends, I can't get my head around this. Here is a script that's supposed to fill a hash from a file ( formatted like "someKey" => "someValue" ) and search for each key through a code directory, to determine which keys are obsolete and should be removed from the file.

But the script doesn't work. Basically it behaves exactly like if it went through a few files at a time, then exits; then when launched again it will parse the next following files. Maybe it's beacause it's late, maybe I really don't understand File::Find, anyway I don't understand what's happening.

#!/usr/bin/perl use strict; use warnings; use File::Find; use Data::Dumper; use 5.010; my %master; ################### sub showhelp { print qq( Usage : $0 lang code_directory \n); exit; } ################## my ( $master, $mydir ) = @ARGV; if ( not $master && $mydir ) { showhelp(); } open my $masterf, '<', $master or die "can't open $master"; while (<$masterf>) { if (/"(\w+)"\s*=>\s*"(.+)",/) { $master{$1} = 0; } } close $masterf; find( \&findFile, $mydir ); sub findFile { return unless -f; searchfile($_); } sub searchfile { my $file=shift; # print "open $file\n"; open my $foundfile, '<', $file or die "can't open $file"; my $first=<$foundfile>; foreach my $k ( keys %master ) { while ( my $line=<$foundfile> ) { if ($line =~ m/$k/ ) { $master{$k}++ ; # print "$k found in $file\n"; } } } close $foundfile; } foreach my $k ( keys %master ) { print "$k NOT USED\n" if $master{$k} == 0; }

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":

  • 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).
