Perl - How to crawl a directory, parse every file in the directory and extract all comments to html file

I need some serious help, I'm new to perl and need help on how to create a perl script that would prompt the user for a directory containing perl files, parse every file in that directory and then extract all comments from each file to individual html files.

code examples or existing modules that alread开发者_JAVA百科y does this would be great.

Thank you!

PPI can be used to parse Perl code files. This should get you started on getting Perl files in a directory (assuming they have .pl extensions) and grabbing the comments. I'm not sure what you mean about the HTML piece:

use warnings;
use strict;
use PPI;

my $dir = shift;
for my $file (glob "$dir/*.pl") {
    my $doc = PPI::Document->new($file);
    for my $com (@{ $doc->find('PPI::Token::Comment') }) {
        print $com->{content};
    }
}

Update: Look at HTML::Template (but it may be overkill).

A simple cpan search with keyword "dir" turned up a whole slew of helpful modules. One of the ones I use a lot is:

IO::Dir

If you have a choice, here's a Ruby script

#!/usr/bin/env ruby 
print "Enter directory: "
directory=File.join(gets.chomp,"*.pl")
directory="/home/yhlee/test/ruby/*.pl"
c=0
Dir[directory].each do |file|
    c+=1
    o = File.open("file_#{c}.html","w")
    File.open(file).each do |line|
        if line[/#/]
            o.write ( line.scan(/;*\s+(#.*)$/)[0].first + "\n" ) if line[/;*\s+#/]
            o.write ( line.scan(/^\s+(#.*)$/)[0].first + "\n") if line[/^\s+#/]
        end
    end
    o.close
end
