NAME

Alien::Build::Plugin::Fetch::Rewrite - Alien::Build plugin to rewrite network requests to local resources

VERSION

version 0.02

SYNOPSIS

In your ~/.alienbuild/rc.pl:

 postload 'Fetch::Rewrite';
 
 sub rewrite {
   my($build, $uri) = @_;
   
   # $build isa Alien::Build
   # $uri isa URI
   
   if($uri->host eq 'ftp.gnu.org')
   {
     # if we see a request to ftp.gnu.org (either ftp or http)
     # we redirect it to the local mirror at
     # http://mirror.example.com/ftp.gnu.org
     $uri->scheme('http');
     $uri->host('mirror.example.com');
     $uri->host('/ftp.gnu.org' . $uri->path);
   }
 }
 
 1;

DESCRIPTION

This plugin allows you to rewrite the URLs for remote networked resources to local resources. This is useful if you are building CPAN modules that rely on Alien distributions where you do not have system packages. It may also seem useful if you do not trust the remote resources, although please keep in mind that like a Makefile.PL or Build.PL, an alienfile is arbitrary Perl code, and should be appropriately vetted before being used in an environment with security requirements.

CAVEATS

This plugin is only able to rewrite URLs that are fetched through the standard Alien::Build URL fetching interface, and only URLs that are supported by LWP::UserAgent and URI.
