These are described -below, and all end in F<.pm>. You may discover compiled library -files (usually ending in F<.so>) or small pieces of modules to be -autoloaded (ending in F<.al>); these were automatically generated -by the installation process. You may also discover files in the -library directory that end in either F<.pl> or F<.ph>. These are -old libraries supplied so that old programs that use them still -run. The F<.pl> files will all eventually be converted into standard -modules, and the F<.ph> files made by B<h2ph> will probably end up -as extension modules made by B<h2xs>. (Some F<.ph> values may -already be available through the POSIX, Errno, or Fcntl modules.) -The B<pl2pm> file in the distribution may help in your conversion, -but it's just a mechanical process and therefore far from bulletproof. - -=head2 Pragmatic Modules - -They work somewhat like compiler directives (pragmata) in that they -tend to affect the compilation of your program, and thus will usually -work well only when used within a C<use>, or C<no>. Most of these -are lexically scoped, so an inner BLOCK may countermand them -by saying: - - no integer; - no strict 'refs'; - no warnings; - -which lasts until the end of that BLOCK. - -Some pragmas are lexically scoped--typically those that affect the -C<$^H> hints variable. Others affect the current package instead, -like C<use vars> and C<use subs>, which allow you to predeclare a -variables or subroutines within a particular I<file> rather than -just a block. Such declarations are effective for the entire file -for which they were declared. You cannot rescind them with C<no -vars> or C<no subs>. - -The following pragmas are defined (and have their own documentation). - -=over 12 - -=item attributes - -Get/set subroutine or variable attributes - -=item attrs - -Set/get attributes of a subroutine (deprecated) - -=item autouse - -Postpone load of modules until a function is used - -=item base - -Establish an ISA relationship with base classes at compile time - -=item bigint - -Transparent BigInteger support for Perl - -=item bignum - -Transparent BigNumber support for Perl - -=item bigrat - -Transparent BigNumber/BigRational support for Perl - -=item blib - -Use MakeMaker's uninstalled version of a package - -=item bytes - -Force byte semantics rather than character semantics - -=item charnames - -Define character names for C<\N{named}> string literal escapes - -=item constant - -Declare constants - -=item diagnostics - -Produce verbose warning diagnostics - -=item encoding - -Allows you to write your script in non-ascii or non-utf8 - -=item encoding::warnings - -Warn on implicit encoding conversions - -=item feature - -Enable new syntactic features - -=item fields - -Compile-time class fields - -=item filetest - -Control the filetest permission operators - -=item if - -C<use> a Perl module if a condition holds - -=item integer - -Use integer arithmetic instead of floating point - -=item less - -Request less of something - -=item lib - -Manipulate @INC at compile time - -=item locale - -Use and avoid POSIX locales for built-in operations - -=item mro - -Method Resolution Order - -=item open - -Set default PerlIO layers for input and output - -=item ops - -Restrict unsafe operations when compiling - -=item overload - -Package for overloading Perl operations - -=item re - -Alter regular expression behaviour - -=item sigtrap - -Enable simple signal handling - -=item sort - -Control sort() behaviour - -=item strict - -Restrict unsafe constructs - -=item subs - -Predeclare sub names - -=item threads - -Perl interpreter-based threads - -=item threads::shared - -Perl extension for sharing data structures between threads - -=item utf8 - -Enable/disable UTF-8 (or UTF-EBCDIC) in source code - -=item vars - -Predeclare global variable names (obsolete) - -=item version - -Perl extension for Version Objects - -=item vmsish - -Control VMS-specific language features - -=item warnings - -Control optional warnings - -=item warnings::register - -Warnings import function - -=back - -=head2 Standard Modules - -Standard, bundled modules are all expected to behave in a well-defined -manner with respect to namespace pollution because they use the -Exporter module.

If you -have a B<man> program but it doesn't find your modules, you'll have -to fix your manpath. See L<perl> for details. If you have no -system B<man> command, you might try the B<perldoc> program. - -Note also that the command C<perldoc perllocal> gives you a (possibly -incomplete) list of the modules that have been further installed on -your system.

They -are usually dynamically loaded into Perl if and when you need them, -but may also be linked in statically. Supported extension modules -include Socket, Fcntl, and POSIX. - -Many popular C extension modules do not come bundled (at least, not -completely) due to their sizes, volatility, or simply lack of time -for adequate testing and configuration across the multitude of -platforms on which Perl was beta-tested. You are encouraged to -look for them on CPAN (described below), or using web search engines -like Alta Vista or Google. - -=head1 CPAN - -CPAN stands for Comprehensive Perl Archive Network; it's a globally -replicated trove of Perl materials, including documentation, style -guides, tricks and traps, alternate ports to non-Unix systems and -occasional binary distributions for these. Search engines for -CPAN can be found at http://www.cpan.org/ - -Most importantly, CPAN includes around a thousand unbundled modules, -some of which require a C compiler to build.

-=head1 Modules: Creation, Use, and Abuse - -(The following section is borrowed directly from Tim Bunce's modules -file, available at your nearest CPAN site.) - -Perl 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 F<.pm> file is required to -exist. See L<perlsub>, L<perltoot>, and L<AutoLoader> for details about -the AUTOLOAD mechanism. - -=head2 Guidelines for Module Creation - -=over 4 - -=item * - -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. - -=item * - -Try to design the new module to be easy to extend and reuse. - -Try to C<use warnings;> (or C<use warnings qw(...);>). -Remember that you can add C<no warnings qw(...);> to individual blocks -of code that need less warnings. - -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: C<die "Invalid" unless ref $ref eq 'FOO'>. -Generally you can delete the C<eq 'FOO'> part with no harm at all. -Let the objects look after themselves! Generally, avoid hard-wired -class names as far as possible. - -Avoid C<< $r->Class::func() >> where using C<@ISA=qw(... Class ...)> and -C<< $r->func() >> would work (see L<perlbot> for more details). - -Use autosplit so little used or newly added functions won't be a -burden to programs that 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 subclass' test? If you say -C<@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: C<< $obj = YOURCLASS->new(); >> -into: C<< $obj = SUBCLASS->new(); >> ? - -Avoid keeping any state information in your packages. It makes it -difficult for multiple other packages to use yours. Keep state -information in objects. - -Always use B<-w>. - -Try to C<use strict;> (or C<use strict qw(...);>). -Remember that you can add C<no strict qw(...);> to individual blocks -of code that need less strictness. - -Always use B<-w>. - -Follow the guidelines in the perlstyle(1) manual. - -Always use B<-w>. - -=item * - -Some simple style guidelines - -The perlstyle manual supplied with Perl has many helpful points. - -Coding style is a matter of personal taste. Many people evolve their -style over several years as they learn what helps them write and -maintain good code. Here's one set of assorted suggestions that -seem to be widely used by experienced developers: - -Use underscores to separate words. It is generally easier to read -$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., C<< $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. - -=item * - -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 C<< $blessed_ref->method >>) -syntax. By convention you can use a leading underscore on names to -indicate informally that they are 'internal' and not for public use. - -(It is actually possible to get private functions by saying: -C<my $subref = sub { ... }; &$subref;>. But there's no way to call that -directly as a method, because 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. - -=item * - -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. Please use -nested module names to group informally or categorize a module. -There should be a very good reason for a module not to have a nested name. -Module names should begin with a capital letter. - -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.misc. - -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 MS-DOS then try to ensure each is -unique in the first 8 characters. Nested modules make this easier. - -=item * - -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. Comp.lang.perl.misc is read by just about -all the people who develop modules and it's the best place to ask. - -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! - -=item * - -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: - -=over 10 - -=item * - -A description of the module/package/extension etc. - -=item * - -A copyright notice - see below. - -=item * - -Prerequisites - what else you may need to have. - -=item * - -How to build it - possible changes to Makefile.PL etc. - -=item * - -How to install it. - -=item * - -Recent changes in this release, especially incompatibilities - -=item * - -Changes / enhancements you plan to make in the future. - -=back - -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. - -=over 4 - -=item * - -Adding a Copyright Notice. - -How you choose to license 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 Licence (see the files README, Copying, and Artistic, -or L<perlgpl> and L<perlartistic>). 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 state something simply like: - - Copyright (c) 1995 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. - -=item * - -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 $VERSION. This should be a floating point -number with at least two digits after the decimal (i.e., hundredths, -e.g, C<$VERSION = "0.01">). Don't use a "1.3.2" style version. -See L<Exporter> for details. - -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.Z). -See perldoc ExtUtils::MakeMaker.pm for details. - -=item * - -How to release and distribute a module. - -It's good idea to post an announcement of the availability of your -module (or the module itself if small) to the comp.lang.perl.announce -Usenet newsgroup. This will at least ensure very wide once-off -distribution. - -If possible, register the module with CPAN. You should -include details of its location in your announcement. - -Some notes about ftp archives: Please use a long descriptive file -name that 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: - - http://www.cpan.org/modules/00modlist.long.html - http://www.cpan.org/modules/04pause.html - -or upload to one of these sites: - - https://pause.kbx.de/pause/ - http://pause.perl.org/pause/ - -and notify <modules@perl.org>. - -By using the 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 me an updated entry for the Module list! - -=item * - -Take care when changing a released module. - -Always strive to remain compatible with previous released versions. -Otherwise try to add a mechanism to revert to the -old behavior if people rely on it. Document incompatible changes. - -=back - -=back - -=head2 Guidelines for Converting Perl 4 Library Scripts into Modules - -=over 4 - -=item * - -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. - -=item * - -Consider the implications. - -All Perl applications that 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? - -=item * - -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. - -=item * - -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: - -=over 10 - -=item * - -Adds the standard Module prologue lines - -=item * - -Converts package specifiers from ' to :: - -=item * - -Converts die(...) to croak(...) - -=item * - -Several other minor changes - -=back - -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! - -=back - -=head2 Guidelines for Reusing Application Code - -=over 4 - -=item * - -Complete applications rarely belong in the Perl Module Library. - -=item * - -Many applications contain some Perl code that could be reused. - -Help save the world! Share your code in a form that makes it easy -to reuse. - -=item * - -Break-out the reusable code into one or more separate module files. - -=item * - -Take the opportunity to reconsider and redesign the interfaces. - -=item * - -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 -e 'use Module::Name; method(@ARGV)' ... -or - % perl -mModule::Name ... (in perl5.002 or higher) - -=back - -=head1 NOTE - -Perl does not enforce private and public parts of its modules as you may -have been used to in other languages like C++, Ada, or Modula-17. Perl -doesn't have an infatuation with enforced privacy. It would prefer -that you stayed out of its living room because you weren't invited, not -because it has a shotgun. - -The module and its user have a contract, part of which is common law, -and part of which is "written". Part of the common law contract is -that a module doesn't pollute any namespace it wasn't asked to. The -written contract for the module (A.K.A. documentation) may make other -provisions. But then you know when you C<use RedefineTheWorld> that -you're redefining the world and willing to take the consequences. |
