NAME
    Acme::CPANModules - List of CPAN modules

SPECIFICATION VERSION
    0.1

VERSION
    This document describes version 0.1.12 of Acme::CPANModules (from Perl
    distribution Acme-CPANModules), released on 2023-11-01.

DESCRIPTION
    With the multitude of modules that are available on CPAN, it is
    sometimes difficult for a user to choose an appropriate module for a
    task or find other modules related in some ways to a module. Various
    projects like CPAN Ratings <http://cpanratings.perl.org/> (where users
    rate and review a distribution; now no longer accepting new submission)
    or MetaCPAN <https://metacpan.org/> (which has a "++" feature where
    logged-in users can press a button to "++" a module and the website will
    tally the number of "++"'s a distribution has) help to some extent.
    There are also various blog posts by Perl programmers which review
    modules, e.g. CPAN Module Reviews by Neil Bowers
    <http://neilb.org/reviews/>.

    Acme::CPANModules is another mechanism to help, to let someone
    categorize modules in whatever way she likes.

    A related website/online service for "CPAN modules" is coming (when I
    eventually get to it :-), or perhaps when I get some help).

CREATING AN ACME::CPANMODULES MODULE
    The first step is to decide on the name of your module. It must be under
    the "Acme::CPANModules::" namespace. For example, if you create a list
    of your favorite modules, you can use
    "Acme::CPANModules::YOURCPANID::Favorite". Or if you are creating a list
    of modules that predict the future, you can choose
    "Acme::CPANModules::PredictingTheFuture". See recommendations for module
    name in "module name" under "RECOMMENDATIONS".

    Inside the module, you must declare a hash named $LIST:

     our $LIST = {
         ...
     };

    The names of the keys in the hash must follow DefHash convention. The
    basic structure is this:

     # an example module list
     {
         summary => 'List of my favorite modules',  # for recommendation of summary, see Recommendations section
         description => <<'_',
     (Some longer description, in Markdown format)

     This is just a list of my favorite modules.
     _

         ## define features to be used by entries. this can be used to generate a
         ## feature comparison matrix among the entries.
         # entry_features => { # optional
         #     feature1 => {summary=>'Summary of feature1', schema=>'str*'}, # default schema is 'bool' if not specified
         #     feature2 => {summary=>'Summary of feature2', ...},
         #     feature3 => {...},
         #     feature4 => {...},
         #     ...
         # },

         entries => [
             {...},
             ...
         ],

         ## specify Bencher scenario properties; "bench_" prefix will be removed
         ## when creating scenario record. see Bencher for more details.
         # bench_datasets => [ ... ],
         # bench_extra_modules => [ ... ],

         ## optional. Instruct cpanmodules script to not show the entries when
         ## viewing the list. This is sometimes convenient when the description
         ## already mentions all the entries.
         #'x.app.cpanmodules.show_entries' => 0,

     }

    Each entry is another DefHash:

     # an example module entry
     {
         module => 'Data::Dump',
         summary => 'Pretty output',
         description => <<'_',
     Data::Dump is my favorite dumping module because it outputs Perl code that
     is pretty and readable.
     _

         # rating => 10, # optional, on a 1-10 scale

         # alternate_modules => [...], # if you are reviewing an undesirable module and want to suggest better alternative(s)

         # related_modules => ['Data::Dump::Color', 'Data::Dumper'], # if you want to specify related modules that are not listed on the other entries of the same list

         ## specify which features this entry supports/doesn't support. this can be
         ## used to generate feature comparison matrix. see
         ## Acme::CPANModulesUtil::FeatureMatrix.
         # features => {
         #     feature1 => 'foo',   # string, value is "foo"
         #     feature2 => 0,       # bool, value is false ("no")
         #                          # since feature3 is not specified for this module, the value is "N/A"
         #     feature4 => {value=>0, summary=>'Irrelevant because foo bar'},  # bool, value is false. with additional note.
         #     ...
         # },

         ## specify Bencher scenario participant's properties; "bench_" prefix will
         ## be removed when creating participant record.
         # bench_code => sub { ... }, # or
         # bench_code_template => 'Data::Dump::dump(<data>)',
         # ...

         # list what functions are in the module. currently this is mainly used for
         # specifying benchmark instructions for the functions.
         functions => {
             func1 => {
                 bench_code_template => 'Data::Dump::dump([])',
             },
         },

     }

    That's it. After you have completed your list, publish your
    Acme::CPANModules module to CPAN.

    Here's a sample of one of the simplest $LIST you can have:

     $LIST = {
         summary => 'Modules that predict the future',
         entries => [
             {module=>'Zorb'},
             {module=>'Madame::Zita'},
         ],
     };

    Here's another, more expanded sample:

     $LIST = {
         summary => 'Modules that predict the future',
         description => <<'_',

    This list catalogs modules that predict the future. Yes, the future is
    unpredictable. But we can try anyway, right?

    _ entries => [ { module => 'Zorb', summary => 'Contact the API for the
    strange crystal Zorb', description => <<'_',

    This module is an API client to Zorb, a strange crystal that supposedly
    fell from the sky in 2017 near Ozark, that can change color depending on
    what you feed to it. The API connects to Zorb API server managed by
    Crooks, Inc.

    _ }, { module => 'Madame::Zita', summary => 'Ask Madame Zita the fortune
    teller', }, ], };

    For more examples, see existing "Acme::CPANModules::*" modules on CPAN.

    If you are using Dist::Zilla to release your distribution, this
    Pod::Weaver plugin might be useful for you:
    Pod::Weaver::Plugin::Acme::CPANModules. It will create an "=head2
    Included modules" section which is POD rendering of your module list so
    users reading your module's documentation can immediately read your
    list.

RECOMMENDATIONS
  module name
    An Acme::CPANModules module is named under "Acme::CPANModules::"
    namespace.

    A personal list should go under your CPAN ID's subnamespace, e.g.
    "Acme::CPANModules::YOURCPANID::Favorite" or
    "Acme::CPANModules::YOURCPANID::Avoided".

    Avoid having "Modules" in the name as it is superfluous, e.g.
    "Acme::CPANModules::TextTable" instead of
    "Acme::CPANModules::TextTableModules".

    Verb is preferrably written in present participle form, e.g. for a list
    of modules that parse JSON: "Acme::CPANModules::ParsingJSON" instead of
    "Acme::CPANModules::ParseJSON".

    Noun that refers to the modules (entries) is preferrably written in
    plural forms, e.g. "Acme::CPANModules::JSONParsers" instead of
    "Acme::CPANModules::JSONParser".

  list summary
    The list summary normally becomes the Acme::CPANModules module's
    Abstract.

    It is recommended to start the summary with "List of modules which/that"
    or "List of my ... modules" to make it clearer that the
    Acme::CPANModules module only contains a list of other modules, instead
    of an actual implementation.

    Some preferred examples:

    Some non-preferred examples:

  entry rating
    Should only be used for personal lists.

  module bundle name
    A distribution that contains several "Acme::CPANModules::*" modules
    should be named "Acme-CPANModulesBundle-*".

    In general, an "Acme::CPANModulesBundle::" module should be named like
    an "Acme::CPANModules::*" module. See recommendations in "module name".

  module bundle abstract
    An "Acme::CPANModulesBundle::" module should have abstract that begins
    with "Bundle of ...".

  other modules
    Other suggested namespaces:

    *   "Acme::CPANModulesUtil::",

        Utility modules that do not contain lists of modules themselves.

    *   "Acme::CPANModulesUtilBundle::",

        For distribution that contains several "Acme::CPANModulesUtil::*"
        modules.

    *   "Acme::CPANModulesRole::"

        For role related to "Acme::CPANModules".

    *   "Acme::CPANModulesRoleBundle::"

        For distribution that contains several "Acme::CPANModulesRole::"
        modules.

USING ACME::CPANMODULES MODULES
    You can install the cpanmodules CLI script (from the App::cpanmodules
    distribution). It can list installed Acme::CPANModules modules and view
    list entries. To install all modules listed on an Acme::CPANModules
    module, you can do something like:

     % cpanmodules ls-entries Org | cpanm -n

    Putting similar/related modules together in an Acme::CPANModules can
    also help the lcpan script find related modules ("lcpan related-mods").
    See the lcpan documentation or "lcpan related-mods --help" for more
    details.

    As mentioned earlier, a website/online service that collects and indexes
    all Acme::CPANModules modules on CPAN is coming in the future.
    Meanwhile, there's MetaCPAN.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
