For large classes or class trees that might not be used during the running of a program, such as L, this can save you large amounts of memory, and decrease the script load time a great deal. B also provides a number of "unsafe" features for runtime generation of classes and implementation of syntactic sugar. These features make use of (evil) UNIVERSAL::AUTOLOAD hooking, and are implemented in this class because these hooks can only be done by a one module, and Class::Autouse serves as a useful place to centralise this kind of evil :) =head2 Class, not Module The terminology "class loading" instead of "module loading" is used intentionally. Modules will only be loaded if they are acting as a class. That is, they will only be loaded during a Class-Emethod call. If you try to use a subroutine directly, say with C, the class will not be loaded and a fatal error will mostly likely occur. This limitation is made to allow more powerfull features in other areas, because we can focus on just loading the modules, and not have to deal with importing. And really, if you are doing OO Perl, you should be avoiding importing wherever possible. =head2 Use as a pragma Class::Autouse can be used as a pragma, specifying a list of classes to load as the arguments. For example use Class::Autouse qw{CGI Data::Manip This::That}; is equivalent to use Class::Autouse; Class::Autouse->autouse( 'CGI' ); Class::Autouse->autouse( 'Data::Manip' ); Class::Autouse->autouse( 'This::That' ); =head2 Developer Mode C features a developer mode. In developer mode, classes are loaded immediately, just like they would be with a normal 'use' statement (although the import sub isn't called). This allows error checking to be done while developing, at the expense of a larger memory overhead. Developer mode is turned on either with the C method, or using :devel in any of the pragma arguments. For example, this would load CGI.pm immediately use Class::Autouse qw{:devel CGI}; While developer mode is roughly equivalent to just using a normal use command, for a large number of modules it lets you use autoloading notation, and just comment or uncomment a single line to turn developer mode on or off. You can leave it on during development, and turn it off for speed reasons when deploying. =head2 Recursive Loading As an alternative to the super loader, the C and C methods can be used to autouse or load an entire tree of classes. For example, the following would give you access to all the L related classes installed on the machine. Class::Autouse->autouse_recursive( 'URI' ); Please note that the loadings will only occur down a single branch of the include path, whichever the top class is located in. =head2 No-Stat Mode For situations where a module exists on a remote disk or another relatively expensive location, you can call C with the :nostat param to disable initial file existance checking at hook time. # Disable autoload-time file existance checking use Class::Autouse qw{:nostat}; =head2 Super Loader Mode Turning on the C super loader allows you to automatically load B class without specifying it first. Thus, the following will work and is completely legal. use Class::Autouse qw{:superloader}; print CGI->b('Wow!'); The super loader can be turned on with either the C>superloader> method, or the C<:superloader> pragma argument. Please note that unlike the normal one-at-a-time autoloading, the super-loader makes global changes, and so is not completely self-contained. It has the potential to cause unintended effects at a distance. If you encounter unusual behaviour, revert to autousing one-at-a-time, or use the recursive loading. Use of the Super Loader is highly discouraged for widely distributed public applications or modules unless unavoidable. B just to be lazy and save a few lines of code. =head2 Loading with Regular Expressions As another alternative to the superloader and recursive loading, a compiled regular expression (qr//) can be supplied as a loader. Note that this loader implements UNIVERSAL::AUTOLOAD, and has the same side effects as the superloader. =head2 Registering a Callback for Dynamic Class Creation If none of the above are sufficient, a CODE reference can be given to Class::Autouse. Any attempt to call a method on a missing class will launch each registered callback until one returns true. Since overriding UNIVERSAL::AUTOLOAD can be done only once in a given Perl application, this feature allows UNIVERSAL::AUTOLOAD to be shared. Please use this instead of implementing your own UNIVERSAL::AUTOLOAD. See the warnings under the L above which apply to all of the features which override UNIVERSAL::AUTOLOAD. It is up to the callback to define the class, the details of which are beyond the scope of this document. See the example below for a quick reference: =head3 Callback Example Any use of a class like Foo::Wrapper autogenerates that class as a proxy around Foo. use Class::Autouse sub { my ($class) = @_; if ($class =~ /(^.*)::Wrapper/) { my $wrapped_class = $1; eval "package $class; use Class::AutoloadCAN;"; die $@ if $@; no strict 'refs'; *{$class . '::new' } = sub { my $class = shift; my $proxy = $wrapped_class->new(@_); my $self = bless({proxy => $proxy},$class); return $self; }; *{$class . '::CAN' } = sub { my ($obj,$method) = @_; my $delegate = $wrapped_class->can($method); return unless $delegate; my $delegator = sub { my $self = shift; if (ref($self)) { return $self->{proxy}->$method(@_); } else { return $wrapped_class->$method(@_); } }; return *{ $class . '::' . $method } = $delegator; }; return 1; } return; }; package Foo; sub new { my $class = shift; bless({@_},$class); } sub class_method { 123 } sub instance_method { my ($self,$v) = @_; return $v * $self->some_property } sub some_property { shift->{some_property} } package main; my $x = Foo::Wrapper->new( some_property => 111, ); print $x->some_property,"\n"; print $x->instance_method(5),"\n"; print Foo::Wrapper->class_method,"\n"; =head2 sugar This method is provided to support "syntactic sugar": allowing the developer to put things into Perl which do not look like regular Perl. There are several ways to do this in Perl. Strategies which require overriding UNIVERSAL::AUTOLOAD can use this interface instead to share that method with the superloader, and with class gnerators. When Perl is unable to find a subroutine/method, and all of the class loaders are exhausted, callbacks registered via sugar() are called. The callbacks recieve the class name, method name, and parameters of the call. If the callback returns nothing, Class::Autouse will continue to iterate through other callbacks. The first callback which returns a true value will end iteration. That value is expected to be a CODE reference which will respond to the AUTOLOAD call. Note: The sugar callback(s) will only be fired by UNIVERSAL::AUTOLOAD after all other attempts at loading the class are done, and after attempts to use regular AUTOLOAD to handle the method call. It is never fired by isa() or can(). It will fire repatedly for the same class. To generate classes, use the regular CODE ref support in autouse(). =head3 Syntactic Sugar Example use Class::Autouse; Class::Autouse->sugar( sub { my $caller = caller(1); my ($class,$method,@params) = @_; shift @params; my @words = ($method,$class,@params); my $sentence = join(" ",@words); return sub { $sentence }; } ); $x = trolls have big ugly hairy feet; print $x,"\n"; # trolls have big ugly hairy feet =head2 mod_perl The mechanism that C uses is not compatible with L. In particular with reloader modules like L. C detects the presence of mod_perl and acts as normal, but will always load all classes immediately, equivalent to having developer mode enabled. This is actually beneficial, as under mod_perl classes should be preloaded in the parent mod_perl process anyway, to prevent them having to be loaded by the Apache child classes. It also saves HUGE amounts of memory. Note that dynamically generated classes and classes loaded via regex CANNOT be pre-loaded automatically before forking child processes. They will still be loaded on demand, often in the child process. See L below. =head2 prefork As with mod_perl, C is compatible with the L module, and all modules specifically autoloaded will be loaded before forking correctly, when requested by L. Since modules generated via callback or regex cannot be loaded automatically by prefork in a generic way, it's advised to use prefork directly to load/generate classes when using mod_perl. =head2 Performance Optimizatons =over =item :nostat Described above, this option is useful when the module in question is on remote disk. =item :noprebless When set, Class::Autouse presumes that objects which are already blessed have their class loaded. This is true in most cases, but will break if the developer intends to reconstitute serialized objects from Data::Dumper, FreezeThaw or its cousins, and has configured Class::Autouse to load the involved classes just-in-time. =item :staticisa When set, presumes that @ISA will not change for a class once it is loaded. The greatest grandparent of a class will be given back the original can/isa implementations which are faster than those Class::Autouse installs into UNIVERSAL. This is a performance tweak useful in most cases, but is left off by default to prevent obscure bugs. =back =head2 The Internal Debugger Class::Autouse provides an internal debugger, which can be used to debug any weird edge cases you might encounter when using it. If the C<$Class::Autouse::DEBUG> variable is true when C is first loaded, debugging will be compiled in. This debugging prints output like the following to STDOUT. Class::Autouse::autouse_recursive( 'Foo' ) Class::Autouse::_recursive( 'Foo', 'load' ) Class::Autouse::load( 'Foo' ) Class::Autouse::_children( 'Foo' ) Class::Autouse::load( 'Foo::Bar' ) Class::Autouse::_file_exists( 'Foo/Bar.pm' ) Class::Autouse::load -> Loading in Foo/Bar.pm Class::Autouse::load( 'Foo::More' ) etc... Please note that because this is optimised out if not used, you can no longer (since 1.20) enable debugging at run-time. This decision was made to remove a large number of unneeded branching and speed up loading. =head1 METHODS =head2 autouse $class, ... The autouse method sets one or more classes to be loaded as required. =head2 load $class The load method loads one or more classes into memory. This is functionally equivalent to using require to load the class list in, except that load will detect and remove the autoloading hook from a previously autoused class, whereas as use effectively ignore the class, and not load it. =head2 devel The devel method sets development mode on (argument of 1) or off (argument of 0). If any classes have previously been autouse'd and not loaded when this method is called, they will be loaded immediately. =head2 superloader The superloader method turns on the super loader. Please note that once you have turned the superloader on, it cannot be turned off. This is due to code that might be relying on it being there not being able to autoload its classes when another piece of code decides they don't want it any more, and turns the superloader off. =head2 class_exists $class Handy method when doing the sort of jobs that C does. Given a class name, it will return true if the class can be loaded ( i.e. in @INC ), false if the class can't be loaded, and undef if the class name is invalid. Note that this does not actually load the class, just tests to see if it can be loaded. Loading can still fail. For a more comprehensive set of methods of this nature, see L. =head2 autouse_recursive $class The same as the C method, but autouses recursively. =head2 load_recursive $class The same as the C method, but loads recursively. Great for checking that a large class tree that might not always be loaded will load correctly. =head1 SUPPORT Bugs should be always be reported via the CPAN bug tracker at L For other issues, or commercial enhancement or support, contact the author. =head1 AUTHORS Adam Kennedy Ecpan@ali.asE Scott Smith Esakoht@cpan.orgE Rob Napier Ernapier@employees.orgE =head1 SEE ALSO L, L =head1 COPYRIGHT Copyright 2002 - 2012 Adam Kennedy.

SYNOPSIS ################################################################## # SAFE FEATURES # Debugging (if you go that way) must be set before the first use BEGIN { $Class::Autouse::DEBUG = 1; } # Turn on developer mode (always load immediately) use Class::Autouse qw{:devel}; # Load a class on method call use Class::Autouse; Class::Autouse->autouse( 'CGI' ); print CGI->b('Wow!'); # Use as a pragma use Class::Autouse qw{CGI}; # Use a whole module tree Class::Autouse->autouse_recursive('Acme'); # Disable module-existance check, and thus one additional 'stat' # per module, at autouse-time if loading modules off a remote # network drive such as NFS or SMB. # (See below for other performance optimizations.) use Class::Autouse qw{:nostat}; ################################################################## # UNSAFE FEATURES # Turn on the Super Loader (load all classes on demand) use Class::Autouse qw{:superloader}; # Autouse classes matching a given regular expression use Class::Autouse qr/::Test$/; # Install a class generator (instead of overriding UNIVERSAL::AUTOLOAD) # (See below for a detailed example) use Class::Autouse \&my_class_generator; # Add a manual callback to UNIVERSAL::AUTOLOAD for syntactic sugar Class::Autouse->sugar(\&my_magic); DESCRIPTION Class::Autouse is a runtime class loader that allows you to specify classes that will only load when a method of that class is called. For large classes or class trees that might not be used during the running of a program, such as Date::Manip, this can save you large amounts of memory, and decrease the script load time a great deal. Class::Autouse also provides a number of "unsafe" features for runtime generation of classes and implementation of syntactic sugar. These features make use of (evil) UNIVERSAL::AUTOLOAD hooking, and are implemented in this class because these hooks can only be done by a one module, and Class::Autouse serves as a useful place to centralise this kind of evil :) Class, not Module The terminology "class loading" instead of "module loading" is used intentionally. Modules will only be loaded if they are acting as a class. That is, they will only be loaded during a Class->method call. If you try to use a subroutine directly, say with "Class::method()", the class will not be loaded and a fatal error will mostly likely occur. This limitation is made to allow more powerfull features in other areas, because we can focus on just loading the modules, and not have to deal with importing. And really, if you are doing OO Perl, you should be avoiding importing wherever possible. Use as a pragma Class::Autouse can be used as a pragma, specifying a list of classes to load as the arguments. For example use Class::Autouse qw{CGI Data::Manip This::That}; is equivalent to use Class::Autouse; Class::Autouse->autouse( 'CGI' ); Class::Autouse->autouse( 'Data::Manip' ); Class::Autouse->autouse( 'This::That' ); Developer Mode "Class::Autouse" features a developer mode. In developer mode, classes are loaded immediately, just like they would be with a normal 'use' statement (although the import sub isn't called). This allows error checking to be done while developing, at the expense of a larger memory overhead. Developer mode is turned on either with the "devel" method, or using :devel in any of the pragma arguments. For example, this would load CGI.pm immediately use Class::Autouse qw{:devel CGI}; While developer mode is roughly equivalent to just using a normal use command, for a large number of modules it lets you use autoloading notation, and just comment or uncomment a single line to turn developer mode on or off. You can leave it on during development, and turn it off for speed reasons when deploying. Recursive Loading As an alternative to the super loader, the "autouse_recursive" and "load_recursive" methods can be used to autouse or load an entire tree of classes. For example, the following would give you access to all the URI related classes installed on the machine. Class::Autouse->autouse_recursive( 'URI' ); Please note that the loadings will only occur down a single branch of the include path, whichever the top class is located in. No-Stat Mode For situations where a module exists on a remote disk or another relatively expensive location, you can call "Class::Autouse" with the :nostat param to disable initial file existance checking at hook time. # Disable autoload-time file existance checking use Class::Autouse qw{:nostat}; Super Loader Mode Turning on the "Class::Autouse" super loader allows you to automatically load ANY class without specifying it first. Thus, the following will work and is completely legal. use Class::Autouse qw{:superloader}; print CGI->b('Wow!'); The super loader can be turned on with either the "Class::Autouse->"superloader> method, or the ":superloader" pragma argument. Please note that unlike the normal one-at-a-time autoloading, the super-loader makes global changes, and so is not completely self-contained. It has the potential to cause unintended effects at a distance. If you encounter unusual behaviour, revert to autousing one-at-a-time, or use the recursive loading. Use of the Super Loader is highly discouraged for widely distributed public applications or modules unless unavoidable. Do not use just to be lazy and save a few lines of code. Loading with Regular Expressions As another alternative to the superloader and recursive loading, a compiled regular expression (qr//) can be supplied as a loader. Note that this loader implements UNIVERSAL::AUTOLOAD, and has the same side effects as the superloader.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS ---------------------------------------------------------------------------- The Artistic License Preamble The intent of this document is to state the conditions under which a Package may be copied, such that the Copyright Holder maintains some semblance of artistic control over the development of the package, while giving the users of the package the right to use and distribute the Package in a more-or-less customary fashion, plus the right to make reasonable modifications. Definitions: - "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification. - "Standard Version" refers to such a Package if it has not been modified, or has been modified in accordance with the wishes of the Copyright Holder. - "Copyright Holder" is whoever is named in the copyright or copyrights for the package. - "You" is you, if you're thinking about copying or distributing this Package. - "Reasonable copying fee" is whatever you can justify on the basis of media cost, duplication charges, time of people involved, and so on. (You will not be required to justify it to the Copyright Holder, but only to the computing community at large as a market that must bear the fee.) - "Freely Available" means that no fee is charged for the item itself, though there may be fees involved in handling the item. It also means that recipients of the item may redistribute it under the same conditions they received it. 1. You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers. 2. You may apply bug fixes, portability fixes and other modifications derived from the Public Domain or from the Copyright Holder. A Package modified in such a way shall still be considered the Standard Version. 3. You may otherwise modify your copy of this Package in any way, provided that you insert a prominent notice in each changed file stating how and when you changed that file, and provided that you do at least ONE of the following: a) place your modifications in the Public Domain or otherwise make them Freely Available, such as by posting said modifications to Usenet or an equivalent medium, or placing the modifications on a major archive site such as ftp.uu.net, or by allowing the Copyright Holder to include your modifications in the Standard Version of the Package. b) use the modified Package only within your corporation or organization. c) rename any non-standard executables so the names do not conflict with standard executables, which must also be provided, and provide a separate manual page for each non-standard executable that clearly documents how it differs from the Standard Version. d) make other distribution arrangements with the Copyright Holder. 4. You may distribute the programs of this Package in object code or executable form, provided that you do at least ONE of the following: a) distribute a Standard Version of the executables and library files, together with instructions (in the manual page or equivalent) on where to get the Standard Version. b) accompany the distribution with the machine-readable source of the Package with your modifications. c) accompany any non-standard executables with their corresponding Standard Version executables, giving the non-standard executables non-standard names, and clearly documenting the differences in manual pages (or equivalent), together with instructions on where to get the Standard Version. d) make other distribution arrangements with the Copyright Holder. 5. You may charge a reasonable copying fee for any distribution of this Package. You may charge any fee you choose for support of this Package. You may not charge a fee for this Package itself. However, you may distribute this Package in aggregate with other (possibly commercial) programs as part of a larger (possibly commercial) software distribution provided that you do not advertise this Package as a product of your own. 6. The scripts and library files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them, and may be sold commercially, and may be aggregated with this Package. 7. C or perl subroutines supplied by you and linked into this Package shall not be considered part of this Package. 8. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission. 9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

(Fixes memory leak AND resolving the Win32 problem listed below) 1.27 Mon 4 Sep 2006 - Upgrading to Module::Install 0.64 1.26 Wed Apr 12 2006 - Debugging change in 1.25 regressed an undocumented 5.6-related bug first fixed in 1.20. Make sure $DEBUG is always defined (Michael Schwern) - Re-introduced the List::Util 1.18 dependency, but stay at 1.17 if on a Win32 (and cygwin, just in case) platform. - Module::Install updated to pre-release of 0.62 1.25 Fri Apr 7 2006 - Expands the can hook to also hook isa (Michael Schwern) - Minor change to debugging (Michael Schwern) - Optimised out the warnings.pm hook change (Michael Schwern) - Module::Install updated to 0.61 1.24 Fri Jan 13 2006 - No functional changes. No need to upgrade. - Updated copyright notice to 2006. - Added t/05_base.t to try and chase down base.pm bug (Failed to find it, but left test so CPAN Tests can validate my assumptions on what should happen and that it happens for them) - Added base.pm as a dep (although unversioned dep) to make sure it is installed on older perls. - Module::Install updated to 0.52 - Decrement List::Util dep to 1.17 as 1.18 fails to build on some platforms. 1.23 Thu Dec 29 2005 - In moving from CVS to SVN I forgot to bring ::Parent with it. (The tests passed spuriously because it found the old version.) - Upgraded Module::Install and shrunk Makefile.PL again to reflect the new features in it. - Upgraded List::Util dependency to 1.18 because of memory leaks and problems with non XS versions of functions we use. 1.22 Wed Dec 21 2005 - Apparently generating spurious warnings on Perl 5.8.1 on Mac OS X when using SVK. Tentatively applying solution. - No change in functionality on any platform. - No need to upgrade unless you are seeing lots of warnings. - Rolled back the File::Spec dependency from 0.82 to 0.80 to avoid needless upgrades in some 5.005 and 5.006 situations. - Moved from older CVS repository to newer SVN repository - Updated Makefile.PL to Module::Install 0.45 1.21 Wed Sep 28 2005 - Documenting ->autouse(@classes) - Tidying up the POD a little to refer to features in an order much more relevant to the reader. 1.20 Tue Aug 18 2005 - Catch and rethrow all error when autoloading during a ->can. - Debugging can now only be done at compile time, and thus is optimised out. The :debug flag is removed and instead you need to preset $Class::Autouse::DEBUG. Given that this was only for my benefit in the first place, it's not appropriate to slow down everything else because of it. 1.18 Tue Jul 26 2005 - Added :nostat module to disable the initial stat checks of modules. 1.17 Tue Mar 8 2005 - Added include('ExtUtils::AutoInstall') by request, to make life easier when installing svk, although I have NFI why :/ 1.16 Tue Feb 15 2005 - Removing braindead pass-through Build.PL file 1.15 Wed Feb 9 2005 - Reorganisation of method order over the last half a dozen versions allowed some invalid uses of indirect object syntax to slip in. This was stupid of me, and I've gotten a lot more explicit in the calling of internal functions now. 1.14 Wed Jan 19 2005 - Allowed a bug to slip in to autouse_recursive (resolved) - Added regression test for the case 1.13 Tue Jan 11 2005 - Updated copyright date - Added no_index entry to makefile to prevent indexing A.pm etc 1.12 Mon Nov 15 2004 - A small change to compile properly when prefork not installed 1.11 Sun Nov 14 2004 - Made dependency on prefork optional - Removed useless $UNIX variable - A few other housekeeping items 1.10 Sat Nov 13 2004 - Integrated with prefork.pm - devel loads all outstanding modules when called - Added some more unit tests 1.04 Mon Jul 6 2004 - Only hijack UNIVERSAL::can for the period that we have live autoload hooks - Various other small improvements 1.03 Mon Dec 8 2003 - Adding another couple of minor error validating changes 1.02 Wed Dec 3 2003 - Minor optimisation, and some pod bugs fixed. 1.01 Sun Nov 9 2003 - Another bug in _can 1.0 Sun Sep 21 2003 - Fixed a bug in _can 0.9 Unknown Date - Unknown Changes 0.8 Unknown Date - Converted to File::Spec. - Added Class::Autouse::Parent - Major changes in the load sequencing to support ->SUPER:: - Lots and lots of general refactoring 0.7 Fri Nov 1 15:52:01 2002 - Debugging Fix - Remove some warnings - Documentation updates 0.6 Wed Apr 3 20:31:41 2002 - Fixed a serious bug that was missed. - Added a load cache to cut back on stat calls - Minor logic speed ups in recursive code 0.5 Fri Mar 15 20:53:34 2002 - Better, nested debugging messages - Debug can be enabled in pragma - One major bug fix - Various minor speed improvements 0.4 Wed Nov 7 14:03:48 2001 - Added autouse_recursive and load_recursive - Fixed major bug in class_exists - Miscellaneous code clean ups - Cleaned up comments 0.3 Wed Sep 26 23:18:10 2001 - Improved hook and loader efficiency - Fixed load method. It works now - Added class_exists method - Documentation tweaks 0.2 Wed Aug 29 22:14:41 2001 - Code cleaned up and much more solid - Added developer mode - Added superloader - Behaves with Carp properly 0.1 Wed Jan 17 11:46:41 2001 - original version Class-Autouse-2.01/t/0000755000175100017510000000000011712711530012755 5ustar adamadamClass-Autouse-2.01/t/13_no_exist.t0000644000175100017510000000060411712711415015277 0ustar adamadam#!/usr/bin/perl use strict; BEGIN { $| = 1; $^W = 1; } # after using Class::Autouse, make sure non-existent class/method # calls fail use Test::More tests => 2; use Class::Autouse; eval { Foo->bar; }; like( $@, qr/locate object method \"bar\" via package \"Foo\"/ ); eval qq{ package Foo; }; eval { Foo->bar; }; like( $@, qr/locate object method \"bar\" via package \"Foo\"/ ); Class-Autouse-2.01/t/09_callback_example.t0000644000175100017510000000332011712711415016721 0ustar adamadam#!/usr/bin/perl use strict; BEGIN { $| = 1; $^W = 1; } # This is the example from the POD # modified slightly to work w/o module deps. use Test::More tests => 4; use Class::Autouse sub { my ($class) = @_; if ($class =~ /(^.*)::Wrapper/) { my $wrapped_class = $1; eval "package $class; ## use Class::AutoloaCAN"; die $@ if $@; no strict 'refs'; *{$class .
