Dist::Zilla::Plugin::Prereqs - list simple prerequisites


version 6.031


In your dist.ini:

  Foo::Bar = 1.002
  MRO::Compat = 10
  Sub::Exporter = 0

You can specify requirements for different phases and relationships with:

  -phase = test
  -relationship = recommends

  Fitz::Fotz    = 1.23
  Text::SoundEx = 3

Remember that if you load two Prereqs plugins, each will needs its own name, added like this:

  [Prereqs / PluginName]
  -phase = test
  -relationship = recommends

  Fitz::Fotz    = 1.23
  Text::SoundEx = 3

If the name is the CamelCase concatenation of a phase and relationship (or just a relationship), it will set those parameters implicitly. If you use a custom name, but it does not specify the relationship, and you didn't specify either -phase or -relationship, it throws the error No -phase or -relationship specified. This is to prevent a typo that makes the name meaningless from slipping by unnoticed.

The example below is equivalent to the example above, except for the name of the resulting plugin:

  [Prereqs / TestRecommends]
  Fitz::Fotz    = 1.23
  Text::SoundEx = 3


This module adds "fixed" prerequisites to your distribution. These are prereqs with a known, fixed minimum version that doesn't change based on platform or other conditions.

You can specify prerequisites for different phases and kinds of relationships. In RuntimeRequires, the phase is Runtime and the relationship is Requires. These are described in more detail in the CPAN::Meta specification.

The phases are:

  • configure

  • build

  • test

  • runtime

  • develop

The relationship types are:

  • requires

  • recommends

  • suggests

  • conflicts

If the phase is omitted, it will default to runtime; thus, specifying "Prereqs / Recommends" in your dist.ini is equivalent to RuntimeRecommends.

Not all of these phases are useful for all tools, especially tools that only understand version 1.x CPAN::Meta files.


This module should work on any version of perl still receiving updates from the Perl 5 Porters. This means it should work on any version of perl released in the last two to three years. (That is, if the most recently released version is v5.40, then this module should work on both v5.40 and v5.38.)

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
