102Exporter - Implements default import method for modules
103
104=head1 SYNOPSIS
105
106In module F<YourModule.pm>:
107
108 package YourModule;
109 require Exporter;
110 @ISA = qw(Exporter);
111 @EXPORT_OK = qw(munge frobnicate); # symbols to export on request
112
113or
114
115 package YourModule;
116 use Exporter 'import'; # gives you Exporter's import() method directly
117 @EXPORT_OK = qw(munge frobnicate); # symbols to export on request
118
119In other files which wish to use C<YourModule>:
120
121 use YourModule qw(frobnicate); # import listed symbols
122 frobnicate ($left, $right) # calls YourModule::frobnicate
123
124Take a look at L</Good Practices> for some variants
125you will like to use in modern Perl code.
126
127=head1 DESCRIPTION
128
129The Exporter module implements an C<import> method which allows a module
130to export functions and variables to its users' namespaces. Many modules
131use Exporter rather than implementing their own C<import> method because
132Exporter provides a highly flexible interface, with an implementation optimised
133for the common case.
134
135Perl automatically calls the C<import> method when processing a
136C<use> statement for a module. Modules and C<use> are documented
137in L<perlfunc> and L<perlmod>. Understanding the concept of
138modules and how the C<use> statement operates is important to
139understanding the Exporter.
140
141=head2 How to Export
142
143The arrays C<@EXPORT> and C<@EXPORT_OK> in a module hold lists of
144symbols that are going to be exported into the users name space by
145default, or which they can request to be exported, respectively. The
146symbols can represent functions, scalars, arrays, hashes, or typeglobs.
147The symbols must be given by full name with the exception that the
148ampersand in front of a function is optional, e.g.
149
150 @EXPORT = qw(afunc $scalar @array); # afunc is a function
151 @EXPORT_OK = qw(&bfunc %hash *typeglob); # explicit prefix on &bfunc
152
153If you are only exporting function names it is recommended to omit the
154ampersand, as the implementation is faster this way.
155
156=head2 Selecting What To Export
157
158Do B<not> export method names!
159
160Do B<not> export anything else by default without a good reason!
161
162Exports pollute the namespace of the module user. If you must export
163try to use C<@EXPORT_OK> in preference to C<@EXPORT> and avoid short or
164common symbol names to reduce the risk of name clashes.
165
166Generally anything not exported is still accessible from outside the
167module using the C<YourModule::item_name> (or C<< $blessed_ref->method >>)
168syntax. By convention you can use a leading underscore on names to
169informally indicate that they are 'internal' and not for public use.
170
171(It is actually possible to get private functions by saying:
172
173 my $subref = sub { ... };
174 $subref->(@args); # Call it as a function
175 $obj->$subref(@args); # Use it as a method
176
177However if you use them for methods it is up to you to figure out
178how to make inheritance work.)
179
180As a general rule, if the module is trying to be object oriented
181then export nothing. If it's just a collection of functions then
182C<@EXPORT_OK> anything but use C<@EXPORT> with caution. For function and
183method names use barewords in preference to names prefixed with
184ampersands for the export lists.
185
186Other module design guidelines can be found in L<perlmod>.
187
188=head2 How to Import
189
190In other files which wish to use your module there are three basic ways for
191them to load your module and import its symbols:
192
193=over 4
194
195=item C<use YourModule;>
196
197This imports all the symbols from YourModule's C<@EXPORT> into the namespace
198of the C<use> statement.
199
200=item C<use YourModule ();>
201
202This causes perl to load your module but does not import any symbols.
203
204=item C<use YourModule qw(...);>
205
206This imports only the symbols listed by the caller into their namespace.
207All listed symbols must be in your C<@EXPORT> or C<@EXPORT_OK>, else an error
208occurs. The advanced export features of Exporter are accessed like this,
209but with list entries that are syntactically distinct from symbol names.
210
211=back
212
213Unless you want to use its advanced features, this is probably all you
214need to know to use Exporter.
215
216=head1 Advanced features
217
218=head2 Specialised Import Lists
219
220If any of the entries in an import list begins with !, : or / then
221the list is treated as a series of specifications which either add to
222or delete from the list of names to import. They are processed left to
223right. Specifications are in the form:
224
225 [!]name This name only
226 [!]:DEFAULT All names in @EXPORT
227 [!]:tag All names in $EXPORT_TAGS{tag} anonymous list
228 [!]/pattern/ All names in @EXPORT and @EXPORT_OK which match
229
230A leading ! indicates that matching names should be deleted from the
231list of names to import. If the first specification is a deletion it
232is treated as though preceded by :DEFAULT. If you just want to import
233extra names in addition to the default set you will still need to
234include :DEFAULT explicitly.
235
236e.g., F<Module.pm> defines:
237
238 @EXPORT = qw(A1 A2 A3 A4 A5);
239 @EXPORT_OK = qw(B1 B2 B3 B4 B5);
240 %EXPORT_TAGS = (T1 => [qw(A1 A2 B1 B2)], T2 => [qw(A1 A2 B3 B4)]);
241
242 Note that you cannot use tags in @EXPORT or @EXPORT_OK.
243 Names in EXPORT_TAGS must also appear in @EXPORT or @EXPORT_OK.
244
245An application using Module can say something like:
246
247 use Module qw(:DEFAULT :T2 !B3 A3);
248
249Other examples include:
250
251 use Socket qw(!/^[AP]F_/ !SOMAXCONN !SOL_SOCKET);
252 use POSIX qw(:errno_h :termios_h !TCSADRAIN !/^EXIT/);
253
254Remember that most patterns (using //) will need to be anchored
255with a leading ^, e.g., C</^EXIT/> rather than C</EXIT/>.
256
257You can say C<BEGIN { $Exporter::Verbose=1 }> to see how the
258specifications are being processed and what is actually being imported
259into modules.
260
261=head2 Exporting without using Exporter's import method
262
263Exporter has a special method, 'export_to_level' which is used in situations
264where you can't directly call Exporter's import method. The export_to_level
265method looks like:
266
267 MyPackage->export_to_level($where_to_export, $package, @what_to_export);
268
269where C<$where_to_export> is an integer telling how far up the calling stack
270to export your symbols, and C<@what_to_export> is an array telling what
271symbols *to* export (usually this is C<@_>). The C<$package> argument is
272currently unused.
273
274For example, suppose that you have a module, A, which already has an
275import function:
276
277 package A;
278
279 @ISA = qw(Exporter);
280 @EXPORT_OK = qw ($b);
281
282 sub import
283 {
284 $A::b = 1; # not a very useful import method
285 }
286
287and you want to Export symbol C<$A::b> back to the module that called
288package A. Since Exporter relies on the import method to work, via
289inheritance, as it stands Exporter::import() will never get called.
290Instead, say the following:
291
292 package A;
293 @ISA = qw(Exporter);
294 @EXPORT_OK = qw ($b);
295
296 sub import
297 {
298 $A::b = 1;
299 A->export_to_level(1, @_);
300 }
301
302This will export the symbols one level 'above' the current package - ie: to
303the program or module that used package A.
304
305Note: Be careful not to modify C<@_> at all before you call export_to_level
306- or people using your package will get very unexplained results!
307
308=head2 Exporting without inheriting from Exporter
309
310By including Exporter in your C<@ISA> you inherit an Exporter's import() method
311but you also inherit several other helper methods which you probably don't
312want. To avoid this you can do
313
314 package YourModule;
315 use Exporter qw( import );
316
317which will export Exporter's own import() method into YourModule.
318Everything will work as before but you won't need to include Exporter in
319C<@YourModule::ISA>.
320
321Note: This feature was introduced in version 5.57
322of Exporter, released with perl 5.8.3.
323
324=head2 Module Version Checking
325
326The Exporter module will convert an attempt to import a number from a
327module into a call to C<< $module_name->require_version($value) >>. This can
328be used to validate that the version of the module being used is
329greater than or equal to the required version.
330
331The Exporter module supplies a default C<require_version> method which
332checks the value of C<$VERSION> in the exporting module.
333
334Since the default C<require_version> method treats the C<$VERSION> number as
335a simple numeric value it will regard version 1.10 as lower than
3361.9. For this reason it is strongly recommended that you use numbers
337with at least two decimal places, e.g., 1.09.
338
339=head2 Managing Unknown Symbols
340
341In some situations you may want to prevent certain symbols from being
342exported. Typically this applies to extensions which have functions
343or constants that may not exist on some systems.
344
345The names of any symbols that cannot be exported should be listed
346in the C<@EXPORT_FAIL> array.
347
348If a module attempts to import any of these symbols the Exporter
349will give the module an opportunity to handle the situation before
350generating an error. The Exporter will call an export_fail method
351with a list of the failed symbols:
352
353 @failed_symbols = $module_name->export_fail(@failed_symbols);
354
355If the C<export_fail> method returns an empty list then no error is
356recorded and all the requested symbols are exported. If the returned
357list is not empty then an error is generated for each symbol and the
358export fails. The Exporter provides a default C<export_fail> method which
359simply returns the list unchanged.
360
361Uses for the C<export_fail> method include giving better error messages
362for some symbols and performing lazy architectural checks (put more
363symbols into C<@EXPORT_FAIL> by default and then take them out if someone
364actually tries to use them and an expensive check shows that they are
365usable on that platform).
366
367=head2 Tag Handling Utility Functions
368
369Since the symbols listed within C<%EXPORT_TAGS> must also appear in either
370C<@EXPORT> or C<@EXPORT_OK>, two utility functions are provided which allow
371you to easily add tagged sets of symbols to C<@EXPORT> or C<@EXPORT_OK>:
372
373 %EXPORT_TAGS = (foo => [qw(aa bb cc)], bar => [qw(aa cc dd)]);
374
375 Exporter::export_tags('foo'); # add aa, bb and cc to @EXPORT
376 Exporter::export_ok_tags('bar'); # add aa, cc and dd to @EXPORT_OK
377
378Any names which are not tags are added to C<@EXPORT> or C<@EXPORT_OK>
379unchanged but will trigger a warning (with C<-w>) to avoid misspelt tags
380names being silently added to C<@EXPORT> or C<@EXPORT_OK>. Future versions
381may make this a fatal error.
382
383=head2 Generating combined tags
384
385If several symbol categories exist in C<%EXPORT_TAGS>, it's usually
386useful to create the utility ":all" to simplify "use" statements.
387
388The simplest way to do this is:
389
390 %EXPORT_TAGS = (foo => [qw(aa bb cc)], bar => [qw(aa cc dd)]);
391
392 # add all the other ":class" tags to the ":all" class,
393 # deleting duplicates
394 {
395 my %seen;
396
397 push @{$EXPORT_TAGS{all}},
398 grep {!$seen{$_}++} @{$EXPORT_TAGS{$_}} foreach keys %EXPORT_TAGS;
399 }
400
401F<CGI.pm> creates an ":all" tag which contains some (but not really
402all) of its categories. That could be done with one small
403change:
404
405 # add some of the other ":class" tags to the ":all" class,
406 # deleting duplicates
407 {
408 my %seen;
409
410 push @{$EXPORT_TAGS{all}},
411 grep {!$seen{$_}++} @{$EXPORT_TAGS{$_}}
412 foreach qw/html2 html3 netscape form cgi internal/;
413 }
414
415Note that the tag names in C<%EXPORT_TAGS> don't have the leading ':'.
416
417=head2 C<AUTOLOAD>ed Constants
418
419Many modules make use of C<AUTOLOAD>ing for constant subroutines to
420avoid having to compile and waste memory on rarely used values (see
421L<perlsub> for details on constant subroutines). Calls to such
422constant subroutines are not optimized away at compile time because
423they can't be checked at compile time for constancy.
424
425Even if a prototype is available at compile time, the body of the
426subroutine is not (it hasn't been C<AUTOLOAD>ed yet). perl needs to
427examine both the C<()> prototype and the body of a subroutine at
428compile time to detect that it can safely replace calls to that
429subroutine with the constant value.
430
431A workaround for this is to call the constants once in a C<BEGIN> block:
432
433 package My ;
434
435 use Socket ;
436
437 foo( SO_LINGER ); ## SO_LINGER NOT optimized away; called at runtime
438 BEGIN { SO_LINGER }
439 foo( SO_LINGER ); ## SO_LINGER optimized away at compile time.
440
441This forces the C<AUTOLOAD> for C<SO_LINGER> to take place before
442SO_LINGER is encountered later in C<My> package.
443
444If you are writing a package that C<AUTOLOAD>s, consider forcing
445an C<AUTOLOAD> for any constants explicitly imported by other packages
446or which are usually used when your package is C<use>d.
447
448=head1 Good Practices
449
450=head2 Declaring C<@EXPORT_OK> and Friends
451
452When using C<Exporter> with the standard C<strict> and C<warnings>
453pragmas, the C<our> keyword is needed to declare the package
454variables C<@EXPORT_OK>, C<@EXPORT>, C<@ISA>, etc.
455
456 our @ISA = qw(Exporter);
457 our @EXPORT_OK = qw(munge frobnicate);
458
459If backward compatibility for Perls under 5.6 is important,
460one must write instead a C<use vars> statement.
461
462 use vars qw(@ISA @EXPORT_OK);
463 @ISA = qw(Exporter);
464 @EXPORT_OK = qw(munge frobnicate);
465
466=head2 Playing Safe
467
468There are some caveats with the use of runtime statements
469like C<require Exporter> and the assignment to package
470variables, which can very subtle for the unaware programmer.
471This may happen for instance with mutually recursive
472modules, which are affected by the time the relevant
473constructions are executed.
474
475The ideal (but a bit ugly) way to never have to think
476about that is to use C<BEGIN> blocks. So the first part
477of the L</SYNOPSIS> code could be rewritten as:
478
479 package YourModule;
480
481 use strict;
482 use warnings;
483
484 our (@ISA, @EXPORT_OK);
485 BEGIN {
486 require Exporter;
487 @ISA = qw(Exporter);
488 @EXPORT_OK = qw(munge frobnicate); # symbols to export on request
489 }
490
491The C<BEGIN> will assure that the loading of F<Exporter.pm>
492and the assignments to C<@ISA> and C<@EXPORT_OK> happen
493immediately, leaving no room for something to get awry
494or just plain wrong.
495
496With respect to loading C<Exporter> and inheriting, there
497are alternatives with the use of modules like C<base> and C<parent>.
498
499 use base qw( Exporter );
500 # or
501 use parent qw( Exporter );
502
503Any of these statements are nice replacements for
504C<BEGIN { require Exporter; @ISA = qw(Exporter); }>
505with the same compile-time effect. The basic difference
506is that C<base> code interacts with declared C<fields>
507while C<parent> is a streamlined version of the older
508C<base> code to just establish the IS-A relationship.
509
510For more details, see the documentation and code of
511L<base> and L<parent>.
512
513Another thorough remedy to that runtime vs.
514compile-time trap is to use L<Exporter::Easy>,
515which is a wrapper of Exporter that allows all
516boilerplate code at a single gulp in the
517use statement.
518
519 use Exporter::Easy (
520 OK => [ qw(munge frobnicate) ],
521 );
522 # @ISA setup is automatic
523 # all assignments happen at compile time
524
525=head2 What not to Export
526
527You have been warned already in L</Selecting What To Export>
528to not export:
529
530=over 4
531
532=item *
533
534method names (because you don't need to
535and that's likely to not do what you want),
536
537=item *
538
539anything by default (because you don't want to surprise your users...
540badly)
541
542=item *
543
544anything you don't need to (because less is more)
545
546=back
547
548There's one more item to add to this list. Do B<not>
549export variable names. Just because C<Exporter> lets you
550do that, it does not mean you should.
551
552 @EXPORT_OK = qw( $svar @avar %hvar ); # DON'T!
553
554Exporting variables is not a good idea. They can
555change under the hood, provoking horrible
556effects at-a-distance, that are too hard to track
557and to fix. Trust me: they are not worth it.
558
559To provide the capability to set/get class-wide
560settings, it is best instead to provide accessors
561as subroutines or class methods instead.
