NAME

Dist::Zilla::Plugin::Prereqs::MatchInstalled - Depend on versions of modules the same as you have installed

VERSION

version 1.001004

SYNOPSIS

This is based on the code of [Author::KENTNL::Prereqs::Latest::Selective], but intended for a wider audience.

[Prereqs::MatchInstalled]
module = My::Module

If you want to automatically add all modules that are prereqs, perhaps instead look at [Prereqs::MatchInstalled::All]

NOTE: Dependencies will only be upgraded to match the Installed version if they're found elsewhere in the dependency tree.

This is designed so that it integrates with other automated version provisioning.

If you're hard-coding module dependencies instead, you will want to place this module after other modules that declare dependencies.

For instance:

[Prereqs]
Foo = 0

[Prereqs::MatchInstalled]
module = Foo

^^ Foo will be upgraded to the version installed.

By default, dependencies that match values of module will be upgraded when they are found in:

phase: build, test, runtime, configure, develop
relation: depends, suggests, recommends

To change this behavior, specify one or more of the following parameters:

applyto_phase = build
applyto_phase = configure

applyto_relation = requires

etc.

For more complex demands, this also works:

applyto = build.requires
applyto = configure.recommends

And that should hopefully be sufficient to cover any conceivable use-case.

Also note, we don't do any sort of sanity checking on the module list you provide.

For instance,

module = strict
module = warning

Will both upgrade the strict and warnings dependencies on your module, regardless of how daft an idea that may be.

And with a little glue

module = perl

Does what you want, but you probably shouldn't rely on that :).

METHODS

mvp_multivalue_args

The following properties can be specified multiple times:

  • applyto
  • applyto_relation
  • applyto_phase
  • modules

mvp_aliases

The module is an alias for modules

current_version_of

$self->current_version_of($package);

Attempts to find the current version of $package.

Returns undef if something went wrong.

register_prereqs

This is for Dist::Zilla::Role::PrereqSource, which gets new prerequisites from this module.

ATTRIBUTES

applyto_phase

Determines which phases will be checked for module dependencies to upgrade.

[Prereqs::MatchInstalled]
applyto_phase = build
applyto_phase = test

Defaults to:

build test runtime configure develop

applyto_relation

Determines which relations will be checked for module dependencies to upgrade.

[Prereqs::MatchInstalled]
applyto_relation = requires

Defaults to:

requires suggests recommends

applyto

Determines the total list of phase/relation combinations which will be checked for dependencies to upgrade.

If not specified, is built from applyto_phase and applyto_relation

[Prereqs::MatchInstalled]
applyto = runtime.requires
applyto = configure.requires

modules

Contains the list of modules that will be searched for in the existing Prereqs stash to upgrade.

[Prereqs::MatchInstalled]
module = Foo
module = Bar
modules = Baz ; this is the same as the previous 2

If you want to automatically add all modules that are prereqs, perhaps instead look at [Prereqs::MatchInstalled::All]

PRIVATE ATTRIBUTES

_applyto_list

Internal.

Contains the contents of applyto represented as an ArrayRef[ArrayRef[Str]]

_modules_hash

Contains a copy of modules as a hash for easy look-up.

PRIVATE METHODS

_build_applyto

_build_applyto_list

_build__modules_hash

_user_wants_upgrade_on
