-Class::MakeMethods::Docs::Changes - History of Class::MakeMethods
-
-=head1 SYNOPSIS
-
-Revision history for Class::MakeMethods.
-
-=head1 CHANGES
-
-=head2 Version 1.010
-
-=over 4
-
-=item 2004/09/06
-
-Moved get_declarations() and associated documentation from Standard module to superclass.
-
-=item 2004/09/03
-
-Developed test.pl test harness with recursive file search to fix Windows "command line too long" errors.
-
-=item 2004/09/01
-
-Moved Template::TextBuilder and Template::DiskCache into Utility:: namespace.
-
-Added support for defaults with -- and -param to Standard get_declarations().
-
-=item 2004/08/12
-
-Began testing and integrating tied-value patches from Dominique Dumont.
-
-=item 2004/04/27
-
-Added method types to Evaled::Hash.
-
-=item 2004/04/23
-
-Added skeleton of a new Evaled::Hash class.
-
-=back
-
-=head2 Version 1.009
-
-=over 4
-
-=item 2003/09/25
-
-Added Emulator::mcoder and compatibility tests.
-
-Released to CPAN as Class-MakeMethods-1.009.tar.gz.
-
-=item 2003/09/22
-
-Added support for lvalue methods to Template and Template::Generic. Added a few tests to demonstrate they're working. Added an example to Docs::Examples.
-
-Added Emulator::accessors and compatibility tests.
-
-Minor documentation improvements.
-
-=back
-
-=head2 Version 1.008
-
-=over 4
-
-=item 2003/09/05
-
-Adjusted layout of test directories in another attempt to solve a MakeMaker/shell-glob issue on Windows that was preventing make test from running correctly. 
-
-Removed Template::PseudoHash, since this package never really worked, as pointed out by a question from Mike Castle. Management of array-based objects can be handled by any of the existing ::Array subclasses, and support for pseudo-hashes would not provide any useful new capabilities.
-
-Added support for "Template::Universal:forward_methods -delegate" and "Template::Generic:object --soft_delegate" based on a suggestion from Peter Chen. Extended behavior of Template -subs handling to make it easy to add such functionality in the future.
-
-Released to CPAN as Class-MakeMethods-1.008.tar.gz.
-
-=item 2003/09/02
-
-Adjusted DESTROY behavior of Template::InsideOut and cleaned up documentation.
-
-=back
-
-=head2 Version 1.007
-
-=over 4
-
-=item 2003/09/01
-
-Made Template definitions automatically import their class's generic
-definitions, if present. This eliminates the need for Generic
-subclasses to explicitly redeclare every method it inherits, and
-should obviate the "missing declaration" problems referenced below.
-
-Updated the names of several Template subclasses, with stubs at
-the old names for backwards compatibility: Flyweight becomes
-InsideOut, Static becomes Global, and Struct becomes Array.
-
-Added Template::Inheritable and basic tests for it.
-
-Eliminated use of legacy Test.pm from remaining tests, except for
-MethodMaker emulation.
-
-Rearranged test directories in an effort to avoid a reported bug
-with the test path of t/*/*.t under Windows.
-
-Released to CPAN as Class-MakeMethods-1.007.tar.gz.
-
-=item 2003/08/27
-
-Added section to Class::MakeMethods/EXTENDING documentation based
-on question from Terrence Brannon.
-
-=item 2003/02/07
-
-Fixed missing declaration of Template::Hash:instance, reported via RT.
-
-=back
-
-=head2 Version 1.006
-
-=over 4
-
-=item 2003/01/26
-
-Additional documentation touch-ups. Moved miscellaneous POD files into the Docs directory.
-
-Added new test scripts from Class-MethodMaker-1.08, although we
-don't yet pass them. In particular, I need to add support for the
-new method types added in 1.04: tie_scalar, tie_list, object_tie_list,
-object_tie_hash
-
-Also need to compare against the changes included in Class-MethodMaker-1.09 and 1.10, which don't seem to include any new test code, but do include functionality changes.
-
-=item 2002/12/12
-
-Re-integrated Template and Emulator packages; the separate distribution
-turned out to be a hastle rather than a convenience. However, in
-order to keep test scripts for each subsystem separate, I'm now
-using a Makefile.PL attribute to specify a two-level deep directory
-tree of test scripts; I hope this doesn't break on Windows...
-
-Fixed possible "use of undefined as a reference" problem in
-Standard::*::array method generators, reported by Jared Rhine.
-
-Tried to improve documentation, based on feedback from Jared Rhine.
-Expunged ReadMe.pod. Extracted method catalogs into Catalog.pod.
-Moved examples to new Example.pod, although that underlines how
-few examples there are.
-
-=back
-
-
-=head2 Version 1.005
-
-=over 4
-
-=item 2002/06/06
-
-Added Autoload interface.
-
-Modifed Attribute interface to add "inheritable" default logic for
-Maker class parameter. (Suggested by Malcolm Cook.)
-
-Fixed typo in documentation for Standard::Universal. (Spotted by
-Malcolm Cook.)
-
-=back
-
-
-=head2 Version 1.004
-
-=over 4
-
-=item 2002/03/23
-
-Released to CPAN as Class-MakeMethods-1.004.tar.gz.
-
-=item 2002/03/16
-
-Allow double-colons between package name and method generator name.
-
-=item 2002/02/19
-
-Fixed related use of undef in Standard::*:hash methods.
-
-=item 2002/02/14
-
-Adjusted Standard::*:hash methods to avoid assuming that the hashref
-already exists.
-
-=item 2002/02/07
-
-Added missing *_reset => clear to Template number --counter interface.
-
-=item 2002/02/02
-
-Adjusted error message in Utility::ArraySplicer
-
-=item 2002/01/26
-

-
-=back
-
-=head2 Version 1.003
-
-=over 4
-
-=item 2002/01/24
-
-Folded "Getting Started Guide" POD into main module documentation.
-
-Renamed Utility::TakeName to Emulator.
-
-Split Template and Emulator packages into their own distributions.
-
-B<Please Note:> This means that to fully upgrade you must retrieve
-all three of these files:
-
-  Class-MakeMethods-1.003.tar.gz 
-  Class-MakeMethods-Template-1.003.tar.gz 
-  Class-MakeMethods-Emulator-1.003.tar.gz 
-
-Of course, if you're not using the Template or Emulator classes,
-there's no need to download them...
-
-
-=item 2002/01/21
-
-Started bumping sub-version numbers and not using sub-sub-versions,
-to shorten distribution names and more closely match standard
-practice.
-
-Added Composite::Inheritable:hook and matching test. Added
-Composite->CurrentResults method to easily access, update composite
-method results.
-
-=back
-
-=head2 Version 1.000.*
-
-=over 4
-
-=item v1.000.16 - 2002/01/21
-
-Released to CPAN as v1.000.016.
-
-=item v1.000.16 - 2002/01/20
-
-Adjusted the hash and array methods in the Standard::* and Composite::*
-packages to properly accept a set-contents call with a single
-reference argument, and to return contents rather than ref in list
-context.
-
-=item v1.000.16 - 2002/01/14
-
-Fixed a subtle bug in a test script inherited from Class::MethodMaker:
-4_Template_hash_hash_array.t and 7_MethodMaker_hash_of_lists.t both
-relied on "keys %hash" returning the keys in a particular order,
-which *almost* always worked, but caused failures on one or more
-Perl version/platform combinations.
-
-
-=item v1.000.15 - 2002/01/14
-
-Released to CPAN as v1.000.015.
-
-=item v1.000.15 - 2002/01/12
-
-Renamed Basic::Static to Basic::Global for consistency with Standard
-and Composite. Hopefully, there aren't many users of this module
-yet; please accept my apologies if this breaks your code.
-
-Eliminated "local @_ = ...", which appears to cause a scoping
-problem on Perl 5.6. Thanks to Adam Spiers for a thorough bug
-report. (See http://www.perlmonks.org/index.pl?node_id=138370 for
-details.)
-
-Extended Template::Generic to support "array --get_set_ref" method
-style requested by Adam Spiers.
-
-Various documentation tweaks, including feedback from Adam Spiers:
-Adjusted documentation to downplay Basic::* modules as a starting
-point, in favor of Standard::* ones. Trimmed out some duplicated
-documentation in favor of more "See LE<lt>...E<gt>" links. Adjusted
-documentation of *::Inheritable packages in an attempt to clarify
-the way in which the inheritance tree is searched for a value.
-
-Factored out common code from Standard::Inheritable and
-Composite::Inheritable to new module, Utility::Inheritable. Factored
-out common code from Standard::Hash and Standard::Array to new
-module, Utility::ArraySplicer. Factored out common code from
-Template::Universal to new module, Utility::Ref. Renamed
-Emulator::TakeName to Utility::TakeName (this is internal use only,
-so there should be no public impact).
-
-
-=item v1.000.15 - 2001/12/01
-
-Adjusted Template::Universal's code for _CALL_METHODS_FROM_HASH_,
-to ensure that method/arg pairs are called in order they were passed
-in.
-
-=item v1.000.15 - 2001/07/04, 2001/07/19
-
-Minor additions to documentation of various method types.
-
-
-=item v1.000.14 - 2001/07/01
-
-Released as v1.000.014.
-
-
-=item v1.000.14 - 2001/06/25, 2001/06/29, 2001/07/01
-
-Removed Makefile rule from Makefile.PL to avoid warnings when used
-with recent versions of ExtUtils::MakeMaker, which also define a
-similar rule. (Based on bug report from Ron Savage.)
-
-Fixed test failure for machines with P5.6 but no Attribute::Handlers.
-(Reported by Ron Savage, Jay Lawrence.)
-
-Added Template::Flyweight:string_index. (But still needs test
-script.)
-
-Added Standard::Universal. (But still needs test scripts.)
-
-Minor touch-ups to ReadMe and Guide documentation.
-
-
-=item v1.000.13 - 2001/05/16, 2001/05/18, 2001/05/20, 2001/06/02, 2001/06/22, 2001/06/24
-
-To date, this module has been circulated under several provisional
-names: it was originally floated as a possible version-2 rewrite
-of Class::MethodMaker, then renamed to Class::Methods when it forked
-from that project, and then briefly to Class::MethodGenerator.
-(Note that it can be surprisingly difficult to comply with both of
-these L<perlmodlib> guidelines: "To be portable each component of
-a module name should be limited   to 11 characters. [...] Always
-try to use two or more whole words.") In the end, I selected
-Class::MakeMethods, as it is two whole words, and is reminiscent
-of Class::MethodMaker without being confusing (I hope!), and I
-believe this issue is now settled.
-
-Standardized syntax for global options; renamed -implementation to
--MakerClass and -target_class to -TargetClass. Moved $TargetClass
-and other context information into %CONTEXT with _context accessor.
-Added ForceInstall.
-
-Completed re-simplification of build directories; we're back to a
-single Makefile, which avoids a warning in P5.6.0.
-
-Added Attribute interface for use with P5.6 and later, based on
-Attribute::Handlers.
-
-Renamed "Simple" subclasses to "Basic". Added documentation and
-initial tests.
-
-Added Standard subclasses with parameter parsing and more powerful
-accessors.
-
-Modified Emulator::Struct to use Standard::* methods. Found struct
-test from P5.7, and added auto_init functionality to match.
-
-Added Composite::* subclasses. 
-
-Added Emulator::AccessorFast.
-
-Added Class::MakeMethods::Guide with introduction and examples.
-
-Continued clean-up effort on Template documentation. Renamed Template
-"attributes" to "method parameters" to avoid confusion with Perl
-attributes. Retitled Template naming rules from "templates" to
-"interfaces".
-
-Changed initialization code expressions of Template::Class in hopes
-of P5.6.1 compatibility. (Problem reported by M Schwern.)
-
-Added 'Template::Generic:new --and_then_init' based on feedback
-from Jay Lawrence.
-
-=back
-

-
-Reversed sense of - and --, as it was in 1.000.1.
-
-Separated source files into separate directories with distinct
-Makefiles and test hierarchies. This should clarify the boundaries
-between the core method-generation code, the common constructor/accessor
-methods, and the various emulator and experimental packages.
-
-
-=item v1.000.8 - 2001/01/19
-
-Following receipt of a suggestion to fork from the maintainer of
-Class::MethodMaker, renamed packge from Class::MethodMaker v2.0 to
-Class::Methods v1.000.
-
-Adjusted documentation to reflect fork, although additional cleanup
-is still needed.

-
-Added Generic -compatibility array index_* and hash_of_arrays *_last
-and *_set methods to match changes in Class::MethodMaker v1.02.
-Added Emulator::MethodMaker support for the '-static' flag. The
-emulator now completely satisfies the enclosed test suites, from
-Class::MethodMaker v0.92 and v1.02.
-
-
-=item v1.000.7 - 2001/01/05, 2001/01/06, 2001/01/07
-
-Moved core code and internal code to Internals.pm. MethodMaker.pm
-now contains only some require statements and the general user
-guide documentation.
-
-Moved ReadMe.pod, Changes.pod, and ToDo.pod into MethodMaker
-directory. Separated Catalog.pod, Extending.pod, RelatedModules.pod.
-
-Included version 1 docs as Class::Methods::OriginalDocs; minor
-revisions for clarity.
-
-Renamed Package subclass to PackageVar, Class to ClassVar.
-
-Added Emulation::Struct subclass.
-
-Added support for shifting targets with make( -target_class =>
-Package, ... ).
-

-subclases.
-
-

-
-Restored -sugar import option for compatibility with earlier
-versions.
-
-Added plural names to "Generic:hash -compatibility" to support
-v0.92 usage.
-
-Replaced use of substr(..., 0, 1) with ... =~ s/^-// for P5.004
-compatibility; problem found by Scott Godin.
-
-Copy @_ before splicing and pushing on to it for P5.004 compatibility.
-
-Expunged duplicate lines from Generic.pm's array_of_objects; found
-by Ron Savage.
-

-run-time import conflict with Generic.pm's behaviors; failure
-reported by Ron Savage.
-
-Added _STATIC_ATTR_{return_value_undefined} attributes to Generic
-string and number to allow overrides of this functionality.
-
-Minor doc touchups and expanded examples section.
-
-

-documentation.  Updated catalog of existing implementations in
-documentation.  Added pointers to some tutorials and books which
-discuss Class::Methods.
-
-Standardized naming of test scripts.
-
-Can now specify default template name, via -default=>"foo".
-
-
-=item v1.000.4 - 2000/11/22
-
-Separated string, number, and boolean from the Generic scalar
-methods.
-
-Provide _disk_cache to shortcut the lengthy _interpret_text_builder
-process.

-
-Moved commonly-accessible information to Universal.
-
-Added block{...} replacement for enhanced behavior templating.
-
-Added modifier mechanism to support -private and -protected.
-
-May need to be able to specify import ordering so that modifiers

-there. Darn.
-
-
-=item v1.000.2 - 2000/10/22
-
-Completed generalization of Generic methods from Static and Hash.
-Rewrote ClassVar and PackageVar to use Generic framework.
-
-Attribute expansion can now substitute values besides name, using
-*{attr}.
-
-Added _diagnostics function and documentation of all failure
-messages.
-
-Added SEE ALSO section to documentation, brief review of Class::*
-on CPAN.  Stumbled across Damian Conway's very nice Class::Contract
-module.
-
-Added Scalar and Flyweight implementations.
-
-
-=item v1.000.1.1 - 2000/10/21

-
-Automated caching for meta-method definition hashes.
-
-Generalized several Static and Hash interfaces into Generic templates.
-Added Static:array and Static:code support.

-behaviors.
-
-
-=item v1.000.1 - 2000/10/19
-
-Support inheritance of templates between meta-methods with -import.
