NAME

ArrayData - Specification for ArrayData::*, modules that contains array data

SPECIFICATION VERSION

0.2

VERSION

This document describes version 0.2.3 of ArrayData (from Perl distribution ArrayData), released on 2021-05-18.

SYNOPSIS

Use one of the ArrayData::* modules.

DESCRIPTION

NOTE: EARLY SPECIFICATION; THINGS WILL STILL CHANGE A LOT.

ArrayData::* modules are modules that contain array data. The array can be stored in an actual Perl array in the source code, or as lines in the DATA section of the source code, or in other places. The array data can be accessed via a standard interface (see ArrayDataRole::Spec::Basic). Some examples of array data are:

Why put data in a Perl module, as a Perl distribution? To leverage the Perl/CPAN toolchain and infrastructure: 1) ease of installation, update, and uninstallation; 2) allowing dependency expression and version comparison; 3) ease of packaging further as OS packages, e.g. Debian packages (converted from Perl distribution); 4) testing by CPAN Testers.

To get started, see ArrayDataRole::Spec::Basic and one of existing ArrayData::* modules.

NAMESPACE ORGANIZATION

ArrayData (this module) is the specification.

All the modules under ArrayData::* should be modules with actual data (base classes should be put in ArrayDataBase::*, roles in ArrayDataRole::*).

More specific subnamespaces for more specific types of elements:

  • ArrayData::String::*

    Strings. (But please see other more specific names.)

  • ArrayData::Word::*

    Dictionary word lists (further classified as (further classified in ArrayData::Word::LanguageCode::* e.g. ArrayData::Word::ID::KBBI). These are designed to replace old WordList::* modules.

  • ArrayData::Phrase::*

    Phrase lists. Designed to replace old WordList::Phrase::* modules.

  • ArrayData::CPAN::*

    Arrays related to CPAN. Designed to replace old WordList::Domain::* modules.

  • ArrayData::Domain::*

    Domain names or suffixes. Designed to replace old WordList::Domain::* modules.

  • ArrayData::HTTP::*

    HTTP-related array data. Designed to replace old WordList::HTTP::* modules.

  • ArrayData::Number::*

    Numbers.

  • ArrayData::Password::*

    Passwords. Designed to replace old WordList::HTTP::* modules.

ArrayDataBase::* the base classes. ArrayDataBases::* are main module names for distributions that bundle multiple base classes.

ArrayDataRole::* the roles. ArrayDataRoles::* are main module names for distributions that bundle multiple roles.

ArrayDataBundle::* are main module names for distributions that contain several ArrayData modules.

FAQ

Should I use WordList or ArrayData (ArrayData::Word)?

Both are okay. If you prefer WordList then by all means use it. Existing WordList::* modules will stay. WordList's API is now frozen. New development and updates to word lists will happen mostly in ArrayData only.

What are the differences between ArrayData and WordList?

Method names:

 Function                       In WordList                                      In ArrayData

 iterating words                each_word()                                      each_item() (from Role::TinyCommons::Iterator::Resettable)
                                reset_iterator() + first_word() + next_word()    reset_iterator() + has_next_item() + get_next_item() (from Role::TinyCommons::Iterator::Resettable)
 checking if a word exists      word_exists()                                    has_item() (from Role::TinyCommons::Collection::FindItem)
 getting all words              all_words()                                      get_all_items() (from Role::TinyCommons::Iterator::Resettable)
 picking random words           pick()                                           pick_items() (from Role::TinyCommons::Collection::PickItems)
