NAME

Alien::Build::Plugin::Download::Negotiate - Download negotiation plugin

VERSION

version 1.10

SYNOPSIS

 use alienfile;
 plugin 'Download' => (
   url => 'http://ftp.gnu.org/gnu/make',
   filter => qr/^make-.*\.tar.\gz$/,
   version => qr/([0-9\.]+)/,
 );

DESCRIPTION

This is a negotiator plugin for downloading packages from the internet. This plugin picks the best Fetch, Decode and Prefer plugins to do the actual work. Which plugins are picked depend on the properties you specify, your platform and environment. It is usually preferable to use a negotiator plugin rather than the Fetch, Decode and Prefer plugins directly from your alienfile.

PROPERTIES

url

The Initial URL for your package. This may be a directory listing (either in HTML or ftp listing format) or the final tarball intended to be downloaded.

filter

This is a regular expression that lets you filter out files that you do not want to consider downloading. For example, if the directory listing contained tarballs and readme files like this:

 foo-1.0.0.tar.gz
 foo-1.0.0.readme

You could specify a filter of qr/\.tar\.gz$/ to make sure only tarballs are considered for download.

version

Regular expression to parse out the version from a filename. The regular expression should store the result in $1.

ssl

If your initial URL does not need SSL, but you know ahead of time that a subsequent request will need it (for example, if your directory listing is on http, but includes links to https URLs), then you can set this property to true, and the appropriate Perl SSL modules will be loaded.

passive

If using FTP, attempt a passive mode transfer first, before trying an active mode transfer.

METHODS

pick

 my($fetch, @decoders) = $plugin->pick;

Returns the fetch plugin and any optional decoders that should be used.
