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;
}

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).
