Alien::Build::Plugin::Prefer::SortVersions(3)

NAME
Alien::Build::Plugin::Prefer::SortVersions - Plugin to sort candidates by most recent first

VERSION
version 1.67

SYNOPSIS
 use alienfile;

 plugin 'Prefer::SortVersions';

DESCRIPTION
Note: in most case you will want to use Alien::Build::Plugin::Download::Negotiate instead. It picks the appropriate fetch plugin based on your platform and environment. In some cases you may need to use this plugin directly instead.

This Prefer plugin sorts the packages that were retrieved from a dir listing, either directly from a Fetch plugin, or from a Decode plugin. It Returns a listing with the items sorted from post preferable to least, and filters out any undesirable candidates.

This plugin updates the file list to include the versions that are extracted, so they can be used by other plugins, such as Alien::Build::Plugin::Prefer::BadVersion.

PROPERTIES

  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. The default "qr/([0-9\.]+)/" is frequently reasonable.
