NAME

Alien::Build::Plugin::Prefer::BadVersion - Plugin to filter out known bad versions

VERSION

version 2.79

SYNOPSIS

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

DESCRIPTION

This plugin allows you to easily filter out known bad versions of libraries in a share install. It doesn't affect a system install at all. You need a Prefer plugin that filters and sorts files first. You may specify the filter in one of three ways:

as a string

Filter out any files that match the given version.

use alienfile;
plugin 'Prefer::BadVersion' => '1.2.3';
as an array

Filter out all files that match any of the given versions.

use alienfile;
plugin 'Prefer::BadVersion' => [ '1.2.3', '1.2.4' ];
as a code reference

Filter out any files return a true value.

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

This plugin can also be used to filter out known bad versions of a library on just one platform. For example, if you know that version 1.2.3 if bad on windows, but okay on other platforms:

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

PROPERTIES

filter

Filter out 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.
