Apache::CVS is a mod_perl handler that provides a web interface to CVS repositories. It's distro includes a subclass, Apache::CVS::HTML, which outputs HTML instead of plain ole text. Perl::Tidy is the core of perltidy, a utility that indents and reformats Perl scripts, as well as provides an excellent syntax highlighter via HTML and CSS. Put the two together and you have a web interface to a CVS repository with syntax highlighting.
package Apache::CVS::Tidy; use strict; use warnings; use base qw(Apache::CVS::HTML); use Perl::Tidy; use CGI qw(start_html); sub print_page_header { my $self = shift; return if $self->page_headers_sent(); $self->request()->print(start_html( -title => 'CVS Repository', -style => { src => '/path/to/perltidy.css' }, )); $self->print_path_links(); $self->page_headers_sent(1); } sub print_text_revision { my ($self,$content) = @_; my $html; perltidy( source => \$content, destination => \$html, argv => '-html -npod -css=/path/to/perltidy.css', errorfile => '/dev/null', ); # big thanks to Beatnik for this little snippet # Apache::CVS::HTML double-spaces the code, this remedies that $html =~ s/\n\n/\n/g; $self->request()->print($html); } 1;

And an example stylesheet:

body {background: #fffff3; color: #35351d} pre { color: #35351d; background: #fffff3; font-family: courier; } a { color: #de022a;} th { background: gray; } .c { color: #777777;} /* comment */ .cm { color: #35351d;} /* comma */ .co { color: #35351d;} /* colon */ .h { color: #CD5555; font-weight:bold;} /* here-doc-target */ .hh { color: #0f6d30; font-style:italic;} /* here-doc-text */ .i { color: #2c2255;} /* identifier */ .j { color: #2c2255; font-weight:bold;} /* label */ .k { color: #8d6b5f; font-weight:bold;} /* keyword */ .m { color: #2c2255; font-weight:bold;} /* subroutine */ .n { color: #B452CD;} /* numeric */ .p { color: #35351d;} /* paren */ .pd { color: #228B22; font-style:italic;} /* pod-text */ .pu { color: #35351d;} /* punctuation */ .q { color: #0f6d30;} /* quote */ .s { color: #35351d;} /* structure */ .sc { color: #35351d;} /* semicolon */ .v { color: #B452CD;} /* v-string */ .w { color: #35351d;} /* bareword */

Last note: i use the -npod option in the argv argument for perltidy() - this prevents POD from being parsed by POD::HTML. Instead, POD is simply italicized, which makes for a faster processing time.
