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


version 6.017


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.


  • Core Dist::Zilla plugins: @Basic, AutoPrereqs.
  • The CPAN Meta specification: "PREREQUISITES" in CPAN::Meta.
