Class::MakeMethods::Docs::ReadMe - About Class::MakeMethods
This is an updated release of Class::MakeMethods, for distribution through CPAN.
This distribution includes the Class::MakeMethods::Template and Class::MakeMethods::Emulator modules which were packaged sepearately in some previous releases.
By passing arguments to "use Class::MakeMethods ..." statements, you can select from a library of hundreds of common types of methods, which are dynamically installed as subroutines in your module, simplifying the code for your class.
This is Class::MakeMethods v1.010, intended for general use.
This module's CPAN registration should read:
Name DSLIP Description -------------- ----- --------------------------------------------- Class:: ::MakeMethods RdpOp Generate common types of methods
In general, this module should work with Perl 5.003 or later, without requring any modules beyond the core Perl distribution.
The following optional feature may not be available on some platforms:
:MakeMethodsubroutine attribute requires Perl version 5.6 and the Attribute::Handlers module (from CPAN).
--lvalue: The lvalue modifier provided by the Template generator subclasses will only work on Perl version 5.6 or later.
You should be able to install this module using the CPAN shell interface:
perl -MCPAN -e 'install Class::MakeMethods'
Alternately, you may retrieve this package from CPAN or from the author's site:
After downloading the distribution, follow the normal procedure to unpack and install it, using the commands shown below or their local equivalents on your system:
tar xzf Class-MakeMethods-*.tar.gz cd Class-MakeMethods-* perl Makefile.PL make test && sudo make install
Thanks to the kind generosity of other members of the Perl community, this distribution is also available repackaged in the FreeBSD "ports" and Linux RPM formats. This may simplify installation for some users, but be aware that these alternate distributions may lag a few versions behind the latest release on CPAN.
This release has been tested succesfully on the following platforms:
5.6.1 on darwin
Earlier releases have also tested OK on the following platforms:
IP30-R12000-irix OpenBSD.i386-openbsd i386-freebsd / i386-freebsd-thread-multi i386-linux i386-netbsd / i386-netbsd-thread-multi i586-linux / i586-linux-thread-multi-ld i686-linux / i686-pld-linux-thread-multi ia64-linux ppc-linux sparc-linux sparc-netbsd sun4-solaris
Some earlier versions failed to "make test" on MSWin32, although a forced installation would still work; that problem should be fixed in the most recent releases.
You may also review the current test results from CPAN-Testers:
This module has been used in a variety of production systems and has been available on CPAN for over two years, with several other distributions dependant on it, so it would be fair to say that it is fully released.
However, while the commonly-used portions are well tested, some of the more obscure combinations of options are less so, and new bug reports do trickle in occasionally. If you do encounter any problems, please inform the author and I'll endeavor to patch them promptly.
Additional features have been outlined for future development, but the intent is support these by adding more options to the declaration interface, while maintaining backward compatibility.
See Class::MakeMethods::Docs::ToDo for other outstanding issues and development plans.
If you have questions or feedback about this module, please feel free to contact the author at the below address. Although there is no formal support program, I do attempt to answer email promptly.
I would be particularly interested in any suggestions towards improving the documentation and correcting any Perl-version or platform dependencies, as well as general feedback and suggested additions.
Bug reports that contain a failing test case are greatly appreciated, and suggested patches will be promptly considered for inclusion in future releases.
