NAME

6       perlmodlib - constructing new Perl modules and finding existing ones
7

THE PERL MODULE LIBRARY

9       Many modules are included in the Perl distribution.  These are
10       described below, and all end in .pm.  You may discover compiled library
11       files (usually ending in .so) or small pieces of modules to be
12       autoloaded (ending in .al); these were automatically generated by the
13       installation process.  You may also discover files in the library
14       directory that end in either .pl or .ph.  These are old libraries
15       supplied so that old programs that use them still run.  The .pl files
16       will all eventually be converted into standard modules, and the .ph
17       files made by h2ph will probably end up as extension modules made by
18       h2xs.  (Some .ph values may already be available through the POSIX,
19       Errno, or Fcntl modules.)  The pl2pm file in the distribution may help
20       in your conversion, but it's just a mechanical process and therefore
21       far from bulletproof.
22
23   Pragmatic Modules
24       They work somewhat like compiler directives (pragmata) in that they
25       tend to affect the compilation of your program, and thus will usually
26       work well only when used within a "use", or "no".  Most of these are
27       lexically scoped, so an inner BLOCK may countermand them by saying:
28
29           no integer;
30           no strict 'refs';
31           no warnings;
32
33       which lasts until the end of that BLOCK.
34
35       Some pragmas are lexically scoped--typically those that affect the $^H
36       hints variable.  Others affect the current package instead, like "use
37       vars" and "use subs", which allow you to predeclare a variables or
38       subroutines within a particular file rather than just a block.  Such
39       declarations are effective for the entire file for which they were
40       declared.  You cannot rescind them with "no vars" or "no subs".
41
42       The following pragmas are defined (and have their own documentation).

1620
1621       To find out all modules installed on your system, including those
1622       without documentation or outside the standard release, just use the
1623       following command (under the default win32 shell, double quotes should
1624       be used instead of single quotes).
1625
1626           % perl -MFile::Find=find -MFile::Spec::Functions -Tlwe \
1627             'find { wanted => sub { print canonpath $_ if /\.pm\z/ },
1628             no_chdir => 1 }, @INC'
1629
1630       (The -T is here to prevent '.' from being listed in @INC.)  They should
1631       all have their own documentation installed and accessible via your
1632       system man(1) command.  If you do not have a find program, you can use
1633       the Perl find2perl program instead, which generates Perl code as output
1634       you can run through perl.  If you have a man program but it doesn't
1635       find your modules, you'll have to fix your manpath.  See perl for
1636       details.  If you have no system man command, you might try the perldoc
1637       program.
1638
1639       Note also that the command "perldoc perllocal" gives you a (possibly
1640       incomplete) list of the modules that have been further installed on
1641       your system. (The perllocal.pod file is updated by the standard
1642       MakeMaker install process.)
1643
1644   Extension Modules
1645       Extension modules are written in C (or a mix of Perl and C).  They are
1646       usually dynamically loaded into Perl if and when you need them, but may
1647       also be linked in statically.  Supported extension modules include
1648       Socket, Fcntl, and POSIX.
1649
1650       Many popular C extension modules do not come bundled (at least, not
1651       completely) due to their sizes, volatility, or simply lack of time for
1652       adequate testing and configuration across the multitude of platforms on
1653       which Perl was beta-tested.  You are encouraged to look for them on
1654       CPAN (described below), or using web search engines like Google or
1655       DuckDuckGo.
1656

CPAN

1658       CPAN stands for Comprehensive Perl Archive Network; it's a globally
1659       replicated trove of Perl materials, including documentation, style
1660       guides, tricks and traps, alternate ports to non-Unix systems and
1661       occasional binary distributions for these.   Search engines for CPAN
1662       can be found at https://www.cpan.org/
1663
1664       Most importantly, CPAN includes around a thousand unbundled modules,
1665       some of which require a C compiler to build.  Major categories of
1666       modules are:
1667
1668       ·   Language Extensions and Documentation Tools
1669
1670       ·   Development Support

1704       ·   Control Flow Utilities (callbacks and exceptions etc)
1705
1706       ·   File Handle and Input/Output Stream Utilities
1707
1708       ·   Miscellaneous Modules
1709
1710       The list of the registered CPAN sites follows.  Please note that the
1711       sorting order is alphabetical on fields:
1712
1713       Continent
1714          |
1715          |-->Country
1716                |

1722
1723       and thus the North American servers happen to be listed between the
1724       European and the South American sites.

Modules: Creation, Use, and Abuse

2359       (The following section is borrowed directly from Tim Bunce's modules
2360       file, available at your nearest CPAN site.)
2361
2362       Perl implements a class using a package, but the presence of a package
2363       doesn't imply the presence of a class.  A package is just a namespace.
2364       A class is a package that provides subroutines that can be used as
2365       methods.  A method is just a subroutine that expects, as its first
2366       argument, either the name of a package (for "static" methods), or a
2367       reference to something (for "virtual" methods).
2368
2369       A module is a file that (by convention) provides a class of the same
2370       name (sans the .pm), plus an import method in that class that can be
2371       called to fetch exported symbols.  This module may implement some of
2372       its methods by loading dynamic C or C++ objects, but that should be
2373       totally transparent to the user of the module.  Likewise, the module
2374       might set up an AUTOLOAD function to slurp in subroutine definitions on
2375       demand, but this is also transparent.  Only the .pm file is required to
2376       exist.  See perlsub, perlobj, and AutoLoader for details about the
2377       AUTOLOAD mechanism.
2378
2379   Guidelines for Module Creation
2380       ·   Do similar modules already exist in some form?
2381
2382           If so, please try to reuse the existing modules either in whole or
2383           by inheriting useful features into a new class.  If this is not
2384           practical try to get together with the module authors to work on
2385           extending or enhancing the functionality of the existing modules.
2386           A perfect example is the plethora of packages in perl4 for dealing
2387           with command line options.
2388
2389           If you are writing a module to expand an already existing set of
2390           modules, please coordinate with the author of the package.  It
2391           helps if you follow the same naming scheme and module interaction
2392           scheme as the original author.
2393
2394       ·   Try to design the new module to be easy to extend and reuse.
2395
2396           Try to "use warnings;" (or "use warnings qw(...);").  Remember that
2397           you can add "no warnings qw(...);" to individual blocks of code
2398           that need less warnings.
2399
2400           Use blessed references.  Use the two argument form of bless to
2401           bless into the class name given as the first parameter of the
2402           constructor, e.g.,:
2403
2404            sub new {
2405                my $class = shift;
2406                return bless {}, $class;
2407            }
2408
2409           or even this if you'd like it to be used as either a static or a
2410           virtual method.
2411
2412            sub new {
2413                my $self  = shift;
2414                my $class = ref($self) || $self;
2415                return bless {}, $class;
2416            }
2417
2418           Pass arrays as references so more parameters can be added later
2419           (it's also faster).  Convert functions into methods where
2420           appropriate.  Split large methods into smaller more flexible ones.
2421           Inherit methods from other modules if appropriate.
2422
2423           Avoid class name tests like: "die "Invalid" unless ref $ref eq
2424           'FOO'".  Generally you can delete the "eq 'FOO'" part with no harm
2425           at all.  Let the objects look after themselves! Generally, avoid
2426           hard-wired class names as far as possible.
2427
2428           Avoid "$r->Class::func()" where using "@ISA=qw(... Class ...)" and
2429           "$r->func()" would work.
2430
2431           Use autosplit so little used or newly added functions won't be a
2432           burden to programs that don't use them. Add test functions to the
2433           module after __END__ either using AutoSplit or by saying:
2434
2435            eval join('',<main::DATA>) || die $@ unless caller();
2436
2437           Does your module pass the 'empty subclass' test? If you say
2438           "@SUBCLASS::ISA = qw(YOURCLASS);" your applications should be able
2439           to use SUBCLASS in exactly the same way as YOURCLASS.  For example,
2440           does your application still work if you change:  "$obj =
2441           YOURCLASS->new();" into: "$obj = SUBCLASS->new();" ?
2442
2443           Avoid keeping any state information in your packages. It makes it
2444           difficult for multiple other packages to use yours. Keep state
2445           information in objects.
2446
2447           Always use -w.
2448
2449           Try to "use strict;" (or "use strict qw(...);").  Remember that you
2450           can add "no strict qw(...);" to individual blocks of code that need
2451           less strictness.
2452
2453           Always use -w.
2454
2455           Follow the guidelines in perlstyle.
2456
2457           Always use -w.
2458
2459       ·   Some simple style guidelines
2460
2461           The perlstyle manual supplied with Perl has many helpful points.
2462
2463           Coding style is a matter of personal taste. Many people evolve
2464           their style over several years as they learn what helps them write
2465           and maintain good code.  Here's one set of assorted suggestions
2466           that seem to be widely used by experienced developers:
2467
2468           Use underscores to separate words.  It is generally easier to read
2469           $var_names_like_this than $VarNamesLikeThis, especially for non-
2470           native speakers of English. It's also a simple rule that works
2471           consistently with VAR_NAMES_LIKE_THIS.
2472
2473           Package/Module names are an exception to this rule. Perl informally
2474           reserves lowercase module names for 'pragma' modules like integer
2475           and strict. Other modules normally begin with a capital letter and
2476           use mixed case with no underscores (need to be short and portable).
2477
2478           You may find it helpful to use letter case to indicate the scope or
2479           nature of a variable. For example:
2480
2481            $ALL_CAPS_HERE   constants only (beware clashes with Perl vars)
2482            $Some_Caps_Here  package-wide global/static
2483            $no_caps_here    function scope my() or local() variables
2484
2485           Function and method names seem to work best as all lowercase.
2486           e.g., "$obj->as_string()".
2487
2488           You can use a leading underscore to indicate that a variable or
2489           function should not be used outside the package that defined it.
2490
2491       ·   Select what to export.
2492
2493           Do NOT export method names!
2494
2495           Do NOT export anything else by default without a good reason!
2496
2497           Exports pollute the namespace of the module user.  If you must
2498           export try to use @EXPORT_OK in preference to @EXPORT and avoid
2499           short or common names to reduce the risk of name clashes.
2500
2501           Generally anything not exported is still accessible from outside
2502           the module using the ModuleName::item_name (or
2503           "$blessed_ref->method") syntax.  By convention you can use a
2504           leading underscore on names to indicate informally that they are
2505           'internal' and not for public use.
2506
2507           (It is actually possible to get private functions by saying: "my
2508           $subref = sub { ... };  &$subref;".  But there's no way to call
2509           that directly as a method, because a method must have a name in the
2510           symbol table.)
2511
2512           As a general rule, if the module is trying to be object oriented
2513           then export nothing. If it's just a collection of functions then
2514           @EXPORT_OK anything but use @EXPORT with caution.
2515
2516       ·   Select a name for the module.
2517
2518           This name should be as descriptive, accurate, and complete as
2519           possible.  Avoid any risk of ambiguity. Always try to use two or
2520           more whole words.  Generally the name should reflect what is
2521           special about what the module does rather than how it does it.
2522           Please use nested module names to group informally or categorize a
2523           module.  There should be a very good reason for a module not to
2524           have a nested name.  Module names should begin with a capital
2525           letter.
2526
2527           Having 57 modules all called Sort will not make life easy for
2528           anyone (though having 23 called Sort::Quick is only marginally
2529           better :-).  Imagine someone trying to install your module
2530           alongside many others.
2531
2532           If you are developing a suite of related modules/classes it's good
2533           practice to use nested classes with a common prefix as this will
2534           avoid namespace clashes. For example: Xyz::Control, Xyz::View,
2535           Xyz::Model etc. Use the modules in this list as a naming guide.
2536
2537           If adding a new module to a set, follow the original author's
2538           standards for naming modules and the interface to methods in those
2539           modules.
2540
2541           If developing modules for private internal or project specific use,
2542           that will never be released to the public, then you should ensure
2543           that their names will not clash with any future public module. You
2544           can do this either by using the reserved Local::* category or by
2545           using a category name that includes an underscore like Foo_Corp::*.
2546
2547           To be portable each component of a module name should be limited to
2548           11 characters. If it might be used on MS-DOS then try to ensure
2549           each is unique in the first 8 characters. Nested modules make this
2550           easier.
2551
2552           For additional guidance on the naming of modules, please consult:

2557
2558       ·   Have you got it right?
2559
2560           How do you know that you've made the right decisions? Have you
2561           picked an interface design that will cause problems later? Have you
2562           picked the most appropriate name? Do you have any questions?
2563
2564           The best way to know for sure, and pick up many helpful
2565           suggestions, is to ask someone who knows. The
2566           <module-authors@perl.org> mailing list is useful for this purpose;
2567           it's also accessible via news interface as perl.module-authors at
2568           nntp.perl.org.
2569
2570           All you need to do is post a short summary of the module, its
2571           purpose and interfaces. A few lines on each of the main methods is
2572           probably enough. (If you post the whole module it might be ignored
2573           by busy people - generally the very people you want to read it!)
2574
2575           Don't worry about posting if you can't say when the module will be
2576           ready - just say so in the message. It might be worth inviting
2577           others to help you, they may be able to complete it for you!
2578
2579       ·   README and other Additional Files.
2580
2581           It's well known that software developers usually fully document the
2582           software they write. If, however, the world is in urgent need of
2583           your software and there is not enough time to write the full
2584           documentation please at least provide a README file containing:
2585
2586           ·         A description of the module/package/extension etc.
2587
2588           ·         A copyright notice - see below.
2589
2590           ·         Prerequisites - what else you may need to have.
2591
2592           ·         How to build it - possible changes to Makefile.PL etc.
2593
2594           ·         How to install it.
2595
2596           ·         Recent changes in this release, especially
2597                     incompatibilities

2599           ·         Changes / enhancements you plan to make in the future.
2600
2601           If the README file seems to be getting too large you may wish to
2602           split out some of the sections into separate files: INSTALL,
2603           Copying, ToDo etc.
2604
2605           ·   Adding a Copyright Notice.
2606
2607               How you choose to license your work is a personal decision.
2608               The general mechanism is to assert your Copyright and then make
2609               a declaration of how others may copy/use/modify your work.
2610
2611               Perl, for example, is supplied with two types of licence: The
2612               GNU GPL and The Artistic Licence (see the files README,
2613               Copying, and Artistic, or perlgpl and perlartistic).  Larry has
2614               good reasons for NOT just using the GNU GPL.
2615
2616               My personal recommendation, out of respect for Larry, Perl, and
2617               the Perl community at large is to state something simply like:
2618
2619                Copyright (c) 1995 Your Name. All rights reserved.
2620                This program is free software; you can redistribute it and/or
2621                modify it under the same terms as Perl itself.
2622
2623               This statement should at least appear in the README file. You
2624               may also wish to include it in a Copying file and your source
2625               files.  Remember to include the other words in addition to the
2626               Copyright.
2627
2628           ·   Give the module a version/issue/release number.
2629
2630               To be fully compatible with the Exporter and MakeMaker modules
2631               you should store your module's version number in a non-my
2632               package variable called $VERSION.  This should be a positive
2633               floating point number with at least two digits after the
2634               decimal (i.e., hundredths, e.g, "$VERSION = "0.01"").  Don't
2635               use a "1.3.2" style version.  See Exporter for details.
2636
2637               It may be handy to add a function or method to retrieve the
2638               number.  Use the number in announcements and archive file names
2639               when releasing the module (ModuleName-1.02.tar.Z).  See perldoc
2640               ExtUtils::MakeMaker.pm for details.

2642           ·   How to release and distribute a module.
2643
2644               If possible, register the module with CPAN. Follow the
2645               instructions and links on:
2646
2647                  https://www.cpan.org/modules/04pause.html
2648
2649               and upload to:
2650
2651                  https://pause.perl.org/
2652
2653               and notify <modules@perl.org>. This will allow anyone to
2654               install your module using the "cpan" tool distributed with
2655               Perl.
2656
2657               By using the WWW interface you can ask the Upload Server to
2658               mirror your modules from your ftp or WWW site into your own
2659               directory on CPAN!
2660
2661           ·   Take care when changing a released module.
2662
2663               Always strive to remain compatible with previous released
2664               versions.  Otherwise try to add a mechanism to revert to the
2665               old behavior if people rely on it.  Document incompatible
2666               changes.

2668   Guidelines for Converting Perl 4 Library Scripts into Modules
2669       ·   There is no requirement to convert anything.
2670
2671           If it ain't broke, don't fix it! Perl 4 library scripts should
2672           continue to work with no problems. You may need to make some minor
2673           changes (like escaping non-array @'s in double quoted strings) but
2674           there is no need to convert a .pl file into a Module for just that.
2675
2676       ·   Consider the implications.
2677
2678           All Perl applications that make use of the script will need to be
2679           changed (slightly) if the script is converted into a module.  Is it
2680           worth it unless you plan to make other changes at the same time?
2681
2682       ·   Make the most of the opportunity.
2683
2684           If you are going to convert the script to a module you can use the
2685           opportunity to redesign the interface.  The guidelines for module
2686           creation above include many of the issues you should consider.
2687
2688       ·   The pl2pm utility will get you started.
2689
2690           This utility will read *.pl files (given as parameters) and write
2691           corresponding *.pm files. The pl2pm utilities does the following:
2692
2693           ·         Adds the standard Module prologue lines
2694
2695           ·         Converts package specifiers from ' to ::
2696
2697           ·         Converts die(...) to croak(...)
2698
2699           ·         Several other minor changes
2700
2701           Being a mechanical process pl2pm is not bullet proof. The converted
2702           code will need careful checking, especially any package statements.
2703           Don't delete the original .pl file till the new .pm one works!
2704
2705   Guidelines for Reusing Application Code
2706       ·   Complete applications rarely belong in the Perl Module Library.
2707
2708       ·   Many applications contain some Perl code that could be reused.
2709
2710           Help save the world! Share your code in a form that makes it easy
2711           to reuse.
2712
2713       ·   Break-out the reusable code into one or more separate module files.
2714
2715       ·   Take the opportunity to reconsider and redesign the interfaces.
2716
2717       ·   In some cases the 'application' can then be reduced to a small
2718
2719           fragment of code built on top of the reusable modules. In these
2720           cases the application could invoked as:
2721
2722                % perl -e 'use Module::Name; method(@ARGV)' ...
2723           or
2724                % perl -mModule::Name ...    (in perl5.002 or higher)
2725

NOTE

2727       Perl does not enforce private and public parts of its modules as you
2728       may have been used to in other languages like C++, Ada, or Modula-17.
2729       Perl doesn't have an infatuation with enforced privacy.  It would
2730       prefer that you stayed out of its living room because you weren't
2731       invited, not because it has a shotgun.
2732
2733       The module and its user have a contract, part of which is common law,
2734       and part of which is "written".  Part of the common law contract is
2735       that a module doesn't pollute any namespace it wasn't asked to.  The
2736       written contract for the module (A.K.A. documentation) may make other
2737       provisions.  But then you know when you "use RedefineTheWorld" that
2738       you're redefining the world and willing to take the consequences.
