NAME

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

VERSION

version 1.67  

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 a 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.
