How can I produce an HTML summary of Perl modules or scripts in a directory?


Is there a tool available that can produce an HTML summary list of perl modules or scripts in a directory tree?

Given

 =head1 NAME

 wibble.pl - does wibble actions

I would like to see something like

<a href="docsforwibble">wibble.pl</a> - does wibble actions
<a href="docsforwobble">wobble.pl</a> - does wobble actions

Solution

  • It is easy to whip one out using Pod::Find from the Pod::Parser distribution.

    The script below creates a rudimentary index file for anything it can find under my site/lib/CGI. It is meant as a demonstration. You are probably better off with pod2html, but this script might still be useful.

    #!/usr/bin/perl
    
    use strict; use warnings;
    use autodie;
    
    use File::Spec::Functions qw( canonpath );
    use HTML::Template;
    use Pod::Find qw(pod_find simplify_name);
    use Pod::Select;
    
    my $mod_top = canonpath 'c:/opt/perl/site/lib/CGI';
    my $html_top = 'c:/opt/perl/html/site/lib/CGI';
    
    my %pods = pod_find($mod_top);
    my @pods;
    
    for my $pod ( sort keys %pods ) {
        (my $link = $pod) =~ s/^\Q$mod_top//;
        $link =~ s/\.\w+\z//;
        $link = "file:///${html_top}${link}.html";
    
        my $name;
        {
            local *STDOUT;
            open STDOUT, '>', \$name;
            podselect({-sections => [ 'NAME' ] }, $pod);
        }
        $name = '' unless defined $name;
        $name =~ s/^=head1\s+NAME\s+//;
        $name =~ s/\s+\z//;
    
        push @pods, {
            POD => $pods{$pod},
            NAME => $name,
            LINK => $link,
        };
    }
    
    my $tmpl = HTML::Template->new(scalarref => \ <<EO_TMPL
    <!DOCTYPE HTML>
    <html>
    <head><title>Index of Perl Modules</title></head>
    <body>
    <h1><TMPL_VAR CATEGORY></h1>
    <dl>
    <TMPL_LOOP PODS>
    <dt><a href="<TMPL_VAR LINK>"><TMPL_VAR POD></a></dt>
    <dd><TMPL_VAR NAME></dd>
    </TMPL_LOOP>
    </ul>
    </body>
    </html>
    EO_TMPL
    );
    
    $tmpl->param(
        CATEGORY => 'CGI',
        PODS => \@pods,
    );
    $tmpl->output(print_to => \*STDOUT);
