Blosxom::Header 0.03005

Blosxom, a weblog application, exports a global variable $header which is a reference to hash. This application passes $header CGI::header() to generate HTTP headers.

When plugin developers modify HTTP headers, they must write as follows:

 package foo;
 $blosxom::header->{'-status'} = '304 Not Modified';

It's obviously bad practice. Blosxom misses the interface to modify them.

Blosxom::Header is a Perl module that allows you to modify them in an object-oriented way:

 my $h = Blosxom::Header->new($blosxom::header);
 $h->set(Status => '304 Not Modified');

You don't need to mind whether to put a hyphen before a key, nor whether to make a key lowercased or camelized.

SYNOPSIS

 # blosxom.cgi
 package blosxom;
 our $header = { -type => 'text/html' };

 # plugins/foo
 package foo;
 use Blosxom::Header;

 my $h = Blosxom::Header->new($blosxom::header);
 my $value = $h->get('type');
 my $bool = $h->exists('type');

 $h->set( type => 'text/plain' );
 $h->remove('type');
