=head1 NAME
perlmodlib - constructing new Perl modules and finding existing ones
=head1 THE PERL MODULE LIBRARY
-A number of modules are included the Perl distribution. These are
-described below, and all end in F<.pm>. 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 module.) The B<pl2pm> file in the distribution may help in your
-conversion, but it's just a mechanical process and therefore far from
-bulletproof.
+Many modules are included the Perl distribution. These are described
+below, and all end in F<.pm>. You may discover compiled library
+file (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 pragmas 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 locally scoped, so an inner BLOCK
-may countermand any of these by saying:
+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.
-Unlike the pragmas that effect the C<$^H> hints variable, the C<use
-vars> and C<use subs> declarations are not BLOCK-scoped. They allow
-you to predeclare a variables or subroutines within a particular
-I<file> rather than just a block. Such declarations are effective
-for the entire file for which they were declared. You cannot rescind
-them with C<no vars> or C<no subs>.
+Some pragmas are lexically scoped--typically those that affect the
+C<$^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).

+
+To find out I<all> modules installed on your system, including
+those without documentation or outside the standard release,
+just do this:
+
+ % find `perl -e 'print "@INC"'` -name '*.pm' -print
+
+They should all have their own documentation installed and accessible
+via your system man(1) command. If you do not have a B<find>
+program, you can use the Perl B<find2perl> program instead, which
+generates Perl code as output you can run through perl. 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.
+
+=head2 Extension Modules
+
+Extension modules are written in C (or a mix of Perl and C). 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 Deja News.
+
+=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. Major categories of
+modules are:

-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 in
-archie(1L), the Perl FAQ or Meta-FAQ, the WWW page, and even with their
-authors before randomly posting asking for their present condition and
-disposition.

+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

scheme as the original author.

+
+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;
+ 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;
+ my $self = shift;
+ my $class = ref($self) || $self;
+ return bless {}, $class;
}
Pass arrays as references so more parameters can be added later
Inherit methods from other modules if appropriate.
Avoid class name tests like: C<die "Invalid" unless ref $ref eq 'FOO'>.
-Generally you can delete the "C<eq 'FOO'>" part with no harm at all.
+Generally you can delete the C<eq 'FOO'> part with no harm at all.
Let the objects look after themselves! Generally, avoid hard-wired
class names as far as possible.
-Avoid C<$r-E<gt>Class::func()> where using C<@ISA=qw(... Class ...)> and

+Avoid C<< $r->Class::func() >> where using C<@ISA=qw(... Class ...)> and

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

+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
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.

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 Exporter.pm in Perl5.001m or later for details.
