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

NAME
Alien::Build::Plugin::Prefer::GoodVersion - Plugin to filter known good versions

VERSION
version 2.84

SYNOPSIS
 use alienfile;
 plugin 'Prefer::GoodVersion' => '1.2.3';

DESCRIPTION
This plugin allows you to specify one or more good versions of a library. This doesn't affect a system install at all. This plugin does the opposite of the "Prefer::BadVersion" plugin. You need need a Prefer plugin that filters and sorts files first. You may specify the filter in one of three ways:

as a string
    Filter any files that match the given version.

     use alienfile;
     plugin 'Prefer::GoodVersion' => '1.2.3';

as an array
    Filter all files that match any of the given versions.

     use alienfile;
     plugin 'Prefer::GoodVersion' => [ '1.2.3', '1.2.4' ];

as a code reference
    Filter any files return a true value.

     use alienfile;
     plugin 'Prefer::GoodVersion' => sub {
       my($file) = @_;
       $file->{version} eq '1.2.3'; # same as the string version above
     };

This plugin can also be used to filter known good versions of a library on just one platform. For example, if you know that version 1.2.3 if good on windows, but the default logic is fine on other platforms:

 use alienfile;
 plugin 'Prefer::GoodVersion' => '1.2.3' if $^O eq 'MSWin32';

PROPERTIES

  filter
Filter entries that match the filter.

CAVEATS
If you are using the string or array mode, then you need an existing Prefer plugin that sets the version number for each file candidate, such as Alien::Build::Plugin::Prefer::SortVersions.

Unless you want to exclude the latest version from a share install, this plugin isn't really that useful. It has no effect on system installs, which may not be obvious at first.
