Introduction

This document is a semi-formal list of Perl 5 Modules. The Perl 4
concept of packages has been extended in Perl 5 and a new standardised
form of reusable software component has been defined: the Module.

Perl 5 Modules typically conform to certain guidelines which make them
easier to use, reuse, integrate and extend.

This list will be posted to comp.lang.perl.announce and comp.answers on
a semi-regular basis. It has two key aims:

   - FOR DEVELOPERS: To change duplication of effort into cooperation.
   - FOR USERS: To quickly locate existing software which can be reused.

This list includes the Perl 5 standard modules, other completed
modules, work-in-progress modules and would-be-nice-to-have ideas for
modules. It also includes guidelines for those wishing to create new
modules including how to name them.

Where Are The Modules Kept?

Most, but not all, of the modules can be found within CPAN, the
Comprehensive Perl Archive Network of mirrored FTP sites. Within the
CPAN scheme the modules described in this list can be found in the
modules/ directory below the CPAN root directory. These are the
currently registered CPAN sites:

All the files under each of the directories listed above should be
identical at all these sites since they are all automatically
maintained mirrors of the master CPAN site. Please use which ever site
is 'nearest' you.

NOTE: If you can't find what you want, or wish to check that what
you've found is the latest version, or wonder why a module mentioned in
this list is not on CPAN, you should contact the person associated with
the module (and not the maintainers of the archives or this list).
Contact details are given at the start of Part 5.

Playing Your Part

Perl is a huge collaborative effort. Everyone who uses perl is
benefiting from the contributions of many hundreds, maybe thousands, of
people. How much time has perl saved you since you started using it?

Do you have any modules you could share with others? For example, you
may have some perl4 scripts from which generally useful, and reusable,
modules could be extracted. There may be many people who would find
your work very useful. Please play your part and contribute to the Perl
community where you can. [ end of sermon :-]

Help save the world! Please submit new entries and updates to us so we
can keep this list up-to-date. Send the new or corrected entry by email
to [e-mail] (or [e-mail] in case the above
doesn't work). Please do not send code to this address. Instead upload
your module, once registered, to the PAUSE site for forwarding on to
CPAN. See section 2, especially 2.6 and 2.11.

        Part 1 - Modules: Creation, Use and Abuse
        =========================================

1)   Perl 5 Module Terminology
     -------------------------

Perl 5 implements a class using a package, but the presence of a
package doesn't imply the presence of a class. A package is just a
namespace. A class is a package that provides subroutines that can be
used as methods. A method is just a subroutine that expects, as its
first argument, either the name of a package (for "static" methods), or
a reference to something (for "virtual" methods).

A module is a file that (by convention) provides a class of the same
name (sans the .pm), plus an import method in that class that can be
called to fetch exported symbols. This module may implement some of its
methods by loading dynamic C or C++ objects, but that should be totally
transparent to the user of the module. Likewise, the module might set
up an AUTOLOAD function to slurp in subroutine definitions on demand,
but this is also transparent. Only the .pm file is required to exist.

2)   Guidelines for Module Creation
     ------------------------------

2.1 Do similar modules already exist in some form?

   If so, please try to reuse the existing modules either in whole or
   by inheriting useful features into a new class.  If this is not
   practical try to get together with the module authors to work on
   extending or enhancing the functionality of the existing modules.
   A perfect example is the plethora of packages in perl4 for dealing
   with command line options.

   If you are writing a module to expand an already existing set of
   modules, please coordinate with the author of the package.  It
   helps if you follow the same naming scheme and module interaction
   scheme as the original author.


2.2 Try to design the new module to be easy to extend and reuse.

   Use blessed references.  Use the two argument form of bless to bless
   into the class name given as the first parameter of the constructor,
   e.g.:

     sub new {
         my $class = shift;
         return bless {}, $class;
     }

   or even this if you'd like it to be used as either a static
   or a virtual method.

     sub new {
         my $self  = shift;
         my $class = ref($self) || $self;
         return bless {}, $class;
     }

   Pass arrays as references so more parameters can be added later
   (it's also faster).  Convert functions into methods where
   appropriate.  Split large methods into smaller more flexible ones.
   Inherit methods from other modules if appropriate.

   Avoid class name tests like: die "Invalid" unless ref $ref eq 'FOO'.
   Generally you can delete the "eq 'FOO'" part with no harm at all.
   Let the objects look after themselves! If it's vital then you can
   use the UNIVERSAL methods isa and can. Generally, avoid hardwired
   class names as far as possible.

   Avoid $r->Class::func() where using @ISA=qw(... Class ...) and
   $r->func() would work (see perlbot man page for more details).

   Use autosplit or the SelfLoader module so little used or newly added
   functions won't be a burden to programs which don't use them. Add
   test functions to the module after __END__ either using autosplit or
   by saying:

     eval join('',<main::DATA>) || die $@ unless caller();

   Does your module pass the 'empty sub-class' test? If you say
   "@SUBCLASS::ISA = qw(YOURCLASS);" your applications should be able
   to use SUBCLASS in exactly the same way as YOURCLASS.  For example,
   does your application still work if you change:  $obj = new YOURCLASS;
   into: $obj = new SUBCLASS; ?

   Avoid keeping any state information in your packages. It makes it
   difficult for multiple other packages to use yours. Keep state
   information in objects.

   Always use -w. Try to "use strict;" (or "use strict qw(...);").
   Remember that you can add "no strict qw(...);" to individual blocks
   of code which need less strictness. Always use -w. Always use -w!
   Follow the guidelines in the perlstyle(1) manual.


2.3 Some simple style guidelines

   The perlstyle manual supplied with perl has many helpful points.

   Coding style is a matter of personal taste. Many people evolve their
   style over several years as they learn what helps them write and
   maintain good code.  Here's one set of assorted suggestions that
   seem to be widely used by experienced developers:

   Use underscores to separate words.  It is generally easier to read
   $var_names_like_this than $VarNamesLikeThis, especially for
   non-native speakers of English. It's also a simple rule that works
   consistently with VAR_NAMES_LIKE_THIS.

   Package/Module names are an exception to this rule. Perl informally
   reserves lowercase module names for 'pragma' modules like integer
   and strict. Other modules normally begin with a capital letter and
   use mixed case with no underscores (need to be short and portable).

   You may find it helpful to use letter case to indicate the scope
   or nature of a variable. For example:

     $ALL_CAPS_HERE   constants only (beware clashes with perl vars)
     $Some_Caps_Here  package-wide global/static
     $no_caps_here    function scope my() or local() variables

   Function and method names seem to work best as all lowercase.
   E.g., $obj->as_string().

   You can use a leading underscore to indicate that a variable or
   function should not be used outside the package that defined it.

   For method calls use either

     $foo = new Foo $arg1, $arg2;     # no parentheses
     $foo = Foo->new($arg1, $arg2);

   but avoid the ambiguous form

     $foo = new Foo($arg1, $arg2);    # Foo() looks like function call

   It can be very helpful if the names of the classes that your module
   uses can be specified as parameters. Consider:

     $dog_class = $args{dog_class} || 'Dog';
     $spot = $dog_class->new(...);

   This allows the user of your module to specify an alternative class
   (typically a subclass of the one you would normally have used).

   On how to report constructor failure, Larry said:

   I tend to see it as exceptional enough that I'll throw a real Perl
   exception (die) if I can't construct an object.  This has a couple
   of advantages right off the bat.  First, you don't have to check the
   return value of every constructor.  Just say "$fido = new Doggie;"
   and presume it succeeded.  This leads to clearer code in most cases.

   Second, if it does fail, you get a better diagnostic than just the
   undefinedness of the return value.  In fact, the exception it throws
   may be quite rich in "stacked" error messages, if it's rethrowing an
   exception caught further in.

   And you can always catch the exception if it does happen using eval {}.

   If, on the other hand, you expect your constructor to fail a goodly
   part of the time, then you shouldn't use exceptions, but you should
   document the interface so that people will know to check the return
   value.  You don't need to use defined(), since a constructor would
   only return a true reference or a false undef.  So good Perl style
   for checking a return value would simply say

      $conn = new Connection $addr
         or die "Couldn't create Connection";

   In general, make as many things meaningful in a Boolean context as
   you can.  This leads to straightforward code.  Never write anything
   like

      if (do_your_thing() == OK)

   in Perl.  That's just asking for logic errors and domain errors.
   Just write

      if (do_your_thing())

   Perl is designed to help you eschew obfuscation, if that's your thing.


2.4 Select what to export.

   Do NOT export method names!
   Do NOT export anything else by default without a good reason!

   Exports pollute the namespace of the module user.  If you must
   export try to use @EXPORT_OK in preference to @EXPORT and avoid
   short or common names to reduce the risk of name clashes.

   Generally anything not exported is still accessible from outside the
   module using the ModuleName::item_name (or $blessed_ref->method)
   syntax.  By convention you can use a leading underscore on names to
   informally indicate that they are 'internal' and not for public use.

   (It is actually possible to get private functions by saying:
   my $subref = sub { ... };  &$subref; But there's no way to call that
   directly as a method, since a method must have a name in the symbol
   table.)

   As a general rule, if the module is trying to be object oriented
   then export nothing. If it's just a collection of functions then
   @EXPORT_OK anything but use @EXPORT with caution.


2.5 Select a name for the module.

   This name should be as descriptive, accurate and complete as
   possible.  Avoid any risk of ambiguity. Always try to use two or
   more whole words.  Generally the name should reflect what is special
   about what the module does rather than how it does it.

   Having 57 modules all called Sort will not make life easy for anyone
   (though having 23 called Sort::Quick is only marginally better :-).
   Imagine someone trying to install your module alongside many others.
   If in any doubt ask for suggestions in comp.lang.perl.modules or
   [e-mail].

   Please use a nested module name to informally group or categorise
   a module, e.g., placing a sorting module into a Sort:: category.
   A module should have a very good reason not to have a nested name.
   Please avoid using more than one level of nesting for module names
   (packages or classes within modules can, of course, use any number).

   Module names should begin with a capital letter. Lowercase names are
   reserved for special modules such as pragmas (e.g., lib and strict).

   Note that module names are not related to class hierarchies.
   A module name Foo::Bar does not in any way imply that Foo::Bar
   inherits from Foo.  Nested names are simply used to provide some
   useful categorisation for humans. The same is generally true for
   all package names.

   Since the CPAN is huge and growing daily, it's essential that
   module authors choose names which lend themselves to browsing.
   That means minimizing acronyms, cute names, and jargon. Also,
   don't make up a new top level category unless you have a good
   reason; please choose an already-existing category when
   possible. Send mail to [e-mail] before you upload, so
   we can help you select a name.

   If you insist on a name that we consider inappropriate, we
   won't prevent you from uploading your module -- but it'll
   remain in your "author" directory and won't be directly visible
   from CPAN/modules/by-module.

   We appreciate the efforts of the contributors who have helped
   make the CPAN the world's largest reusable code repository.
   Please help us enhance it by working with us to choose the
   best name possible.

   If you are developing a suite of related modules/classes it's good
   practice to use nested classes with a common prefix as this will
   avoid namespace clashes. For example:  Xyz::Control, Xyz::View,
   Xyz::Model etc. Use the modules in this list as a naming guide.

   If adding a new module to a set, follow the original author's
   standards for naming modules and the interface to methods in
   those modules.

   If developing modules for private internal or project specific use,
   that will never be released to the public, then you should ensure
   that their names will not clash with any future public module. You
   can do this either by using the reserved Local::* category or by
   using a category name that includes an underscore like Foo_Corp::*.

   To be portable each component of a module name should be limited to
   11 characters. If it might be used on DOS then try to ensure each is
   unique in the first 8 characters. Nested modules make this easier.


2.6 Have you got it right?

   How do you know that you've made the right decisions? Have you
   picked an interface design that will cause problems later? Have
   you picked the most appropriate name? Do you have any questions?

   The best way to know for sure, and pick up many helpful suggestions,
   is to ask someone who knows. The comp.lang.perl.modules Usenet
   newsgroup is read by just about all the people who develop modules
   and it's generally the best place to ask first. If you need more
   help then try [e-mail].

   All you need to do is post a short summary of the module, its
   purpose and interfaces. A few lines on each of the main methods is
   probably enough. (If you post the whole module it might be ignored
   by busy people - generally the very people you want to read it!)

   Don't worry about posting if you can't say when the module will be
   ready - just say so in the message. It might be worth inviting
   others to help you, they may be able to complete it for you!


2.7 README and other Additional Files.

   It's well known that software developers usually fully document the
   software they write. If, however, the world is in urgent need of
   your software and there is not enough time to write the full
   documentation please at least provide a README file containing:

   - A description of the module/package/extension etc.
   - A copyright notice - see below.
   - Prerequisites - what else you may need to have.
   - How to build it - possible changes to Makefile.PL etc.
   - How to install it.
   - Recent changes in this release, especially incompatibilities
   - Changes / enhancements you plan to make in the future.

   If the README file seems to be getting too large you may wish to
   split out some of the sections into separate files: INSTALL,
   Copying, ToDo etc.


2.8 Adding a Copyright Notice.

   How you choose to licence your work is a personal decision.
   The general mechanism is to assert your Copyright and then make
   a declaration of how others may copy/use/modify your work.

   Perl, for example, is supplied with two types of licence: The GNU
   GPL and The Artistic License (see the files README, Copying and
   Artistic).  Larry has good reasons for NOT just using the GNU GPL.

   My personal recommendation, out of respect for Larry, Perl and the
   perl community at large is to simply state something like:

     Copyright (c) 1997 Your Name. All rights reserved.
     This program is free software; you can redistribute it and/or
     modify it under the same terms as Perl itself.

   This statement should at least appear in the README file. You may
   also wish to include it in a Copying file and your source files.
   Remember to include the other words in addition to the Copyright.


2.9 Give the module a version/issue/release number.

   To be fully compatible with the Exporter and MakeMaker modules you
   should store your module's version number in a non-my package
   variable called $VERSION.  This should be a valid floating point
   number with at least two digits after the decimal (ie hundredths,
   e.g, $VERSION = "0.01").  See Exporter.pm for details.

   Don't use a "1.3.2" style version directly. If you use RCS or a
   similar system which supports multilevel versions/branches you can
   use this (but put it all on one line for MakeMaker VERSION_FROM):

    $VERSION = do { my @r=(q$Revision: 2.99 $=~/\d+/g);
                    sprintf "%d."."%02d"x$#r,@r };

   It may be handy to add a function or method to retrieve the number.
   Use the number in announcements and archive file names when
   releasing the module (ModuleName-1.02.tar.gz).
   See perldoc ExtUtils::MakeMaker.pm for details.


2.10 Listing Prerequisites in a Bundle module

   If your module needs some others that are available on CPAN, you
   might consider creating a 'bundle' module that lists all the
   prerequisites in a standardized way. Automatic installation software
   such as the CPAN.pm module can take advantage of such a listing and
   enable your users to install all prerequisites and your own module
   with one single command. See the CPAN.pm module for details.


2.11 How to release and distribute a module.

   By far the best way to release modules is to register yourself with
   the Perl Authors Upload Server (PAUSE). By registering with PAUSE
   you will be able to easily upload (or mirror) your modules to the
   PAUSE server from where they will be mirrored to CPAN sites across
   the planet.

   It's good idea to post an announcement of the availability of your
   module to the comp.lang.perl.announce Usenet newsgroup.  This will
   at least ensure very wide once-off distribution.

   If not using PAUSE you should place the module into a major ftp
   archive and include details of it's location in your announcement.
   Some notes about ftp archives: Please use a long descriptive file
   name which includes the version number. Most incoming directories
   will not be readable/listable, i.e., you won't be able to see your
   file after uploading it. Remember to send your email notification
   message as soon as possible after uploading else your file may get
   deleted automatically. Allow time for the file to be processed
   and/or check the file has been processed before announcing its
   location.

   FTP Archives for Perl Modules:

   Follow the instructions and links on

   or upload to one of these sites:

   and notify [e-mail].

   By using the PAUSE WWW interface you can ask the Upload Server to
   mirror your modules from your ftp or WWW site into your own
   directory on CPAN. Please remember to send us an updated entry for
   the Module list!


2.12 Take care when changing a released module.

   Always strive to remain compatible with previous released versions
   (see 2.2 above) Otherwise try to add a mechanism to revert to the
   old behaviour if people rely on it. Document incompatible changes.



3) Guidelines for Converting Perl 4 Library Scripts into Modules
   -------------------------------------------------------------

3.1 There is no requirement to convert anything.

   If it ain't broke, don't fix it! Perl 4 library scripts should
   continue to work with no problems. You may need to make some minor
   changes (like escaping non-array @'s in double quoted strings) but
   there is no need to convert a .pl file into a Module for just that.
   See perltrap.pod for details of all known perl4-to-perl5 issues.


3.2 Consider the implications.

   All the perl applications which make use of the script will need to
   be changed (slightly) if the script is converted into a module.  Is
   it worth it unless you plan to make other changes at the same time?


3.3 Make the most of the opportunity.

   If you are going to convert the script to a module you can use the
   opportunity to redesign the interface. The 'Guidelines for Module
   Creation' above include many of the issues you should consider.


3.4 The pl2pm utility will get you started.

   This utility will read *.pl files (given as parameters) and write
   corresponding *.pm files. The pl2pm utilities does the following:
   - Adds the standard Module prologue lines
   - Converts package specifiers from ' to ::
   - Converts die(...) to croak(...)
   - Several other minor changes
   Being a mechanical process pl2pm is not bullet proof. The converted
   code will need careful checking, especially any package statements.
   Don't delete the original .pl file till the new .pm one works!



4) Guidelines for Reusing Application Code
   ---------------------------------------

4.1 Complete applications rarely belong in the Perl Module Library.

4.2 Many applications contain some perl code which could be reused.
    Help save the world! Share your code in a form that makes it easy
    to reuse.

4.3 Break-out the reusable code into one or more separate module files.

4.4 Take the opportunity to reconsider and redesign the interfaces.

4.5 In some cases the 'application' can then be reduced to a small
    fragment of code built on top of the reusable modules. In these
    cases the application could invoked as:

         perl -MModule::Name -e 'func(@ARGV)'


=======================================================================


              Part 2 - The Perl 5 Module List
              ===============================


The remainder of this document is divided up into sections. Each
section deals with a particular topic and lists all known modules
related to that topic.  Modules are only listed in one section so
check all sections that might related to your particular needs.

All the information corresponds to the latest updates we have received.
We don't record the version number or release dates of the listed
Modules. Nor do we record the locations of these Modules. Consult the
contact, try the usual perl CPAN sites or ask in comp.lang.perl.modules.
Please do *not* ask us directly, we simply don't have the time. Sorry.


1) Module Listing Format

Each Module listing is very short. The main goal is to simply publish
the existence of the modules, or ideas for modules, and enough contact
information for you to find out more. Each listing includes some
characters which convey (approximate) basic status information.

For example:

Name           DSLI  Description                                  Info
-------------  ----  -------------------------------------------- -----
Fcntl          Sdcf  Defines fcntl() constants (see File::Lock)   JHI

Where the 'DSLI' characters have the following meanings:

  D - Development Stage  (Note: *NO IMPLIED TIMESCALES*):
    i   - Idea, listed to gain consensus or as a placeholder
    c   - under construction but pre-alpha (not yet released)
    a/b - Alpha/Beta testing
    R   - Released
    M   - Mature (no rigorous definition)
    S   - Standard, supplied with Perl 5

  S - Support Level:
    m   - Mailing-list
    d   - Developer
    u   - Usenet newsgroup comp.lang.perl.modules
    n   - None known, try comp.lang.perl.modules

  L - Language Used:
    p   - Perl-only, no compiler needed, should be platform independent
    c   - C and perl, a C compiler will be needed
    h   - Hybrid, written in perl with optional C code, no compiler needed
    +   - C++ and perl, a C++ compiler will be needed
    o   - perl and another language other than C or C++

  I - Interface Style
    f   - plain Functions, no references used
    h   - hybrid, object and function interfaces available
    r   - some use of unblessed References or ties
    O   - Object oriented using blessed references and/or inheritance

Where letters are missing they can usually be inferred from the
others.  For example 'i' implies 'id', 'S' implies 'Su'.

The Info column gives a contact reference 'tag'. Lookup this tag in
the "Information / Contact Reference Details" section in Pert 3 of
this document. If no contact is given always try asking in
comp.lang.perl.modules.

Most Modules are nested in categories such as IPC::Open2 and IPC::Open3.
These are shown as 'IPC::' on one line then each module listed below
with a '::' prefix.


Ideas For Adoption

Modules listed as in the 'i' Development Stage with no contact
reference are ideas without an owner. Feel free to 'adopt' these but
please let me know so that we can update the list and thus inform anyone
else who might be interested. Adoption simply means that you either
hope to implement the module one day or would like to cooperate with
anyone else who might be interested in implementing it.


Cooperation

Similarly, if an idea that interests you has been adopted by someone
please contact them so you can share ideas.  Just because an idea has
been adopted does NOT imply that it's going to be implemented. Just
because a module is listed and being implemented does NOT mean it'll
get finished. Waiting silently in the hope that the Module will appear
one day is unlikely to be fruitful! Offer to help. Cooperate. Pool your
efforts. Go on, try it!

The same applies to modules in all states. Most modules are developed
in limited spare time. If you're interested in a module don't just wait
for it to happen, offer to help.

Module developers should feel free to announce incomplete work early.
If you're not going to be able to spend much time on something then say
so. If you invite cooperation maybe someone will implement it for you!

           Part 3 - Big Projects Registry
           ==============================


This section of the Module List is devoted to listing "Big Projects".
I don't want to define Big (or even Project) here. Hopefully the items
below speak for themselves. Almost all are just ideas, though some have
been dabbled with and some are active projects.

These are ideas for people with very strong skills and lots of time.
Please talk, and listen, to Larry and the perl5-porters _before_
starting to do any work on projects which relate to the core
implementation of Perl.

Ask not when these will be implemented, ask instead how you can help
implement them.


1) Items in the Todo File

The Todo supplied with Perl lists over 50 items in categories ranging
from "Would be nice to have" to "Vague possibilities".

Contacts: P5P


2) Multi-threading

This is really two projects. True threads (e.g., POSIX) using multiple
independant perl interpreter structures and simple timeslicing of
'tasks' within a single perl interpreter. True threads requires
operating system support or an external thread library, simple
timeslicing does not (and should be portable to all platforms).

Malcolm Beattie <[e-mail]> has done extensive work in
this area and is folding this work into Perl now for version 5.005 or
5.006.

Contacts: MICB P5P


3) Object Management Group CORBA & IDL

Contacts: COPEML BARTS


4) Expand Tied Array Interface

LEN, PUSH, POP, SHIFT, UNSHIFT and a fallback to SPLICE are needed.
Complicated by very widespread use of arrays within perl internals.

Contacts: P5P CHIPS


5) Extend Yacc To Write XS Code

Contacts: JAKE NI-S P5P


6) Approximate Matching Regular Expressions

Add support for approximate matching m/.../a (like the agrep utility).

Contacts: JHI

           Part 4 - Standards Cross-reference
           ==================================

This section aims to provide a cross reference between standards that
exist in the computing world and perl modules which have been written
to implement or interface to those standards.

It also aims to encourage module authors to consider any standards that
might relate to the modules they are developing.
