In this example we provide our own metaclass trait, and we also export a \f(CW\*(C`has_table\*(C'\fR sugar function. .PP The \f(CW\*(C`with_meta\*(C'\fR parameter specifies a list of functions that should be wrapped before exporting. The wrapper simply ensures that the importing package's appropriate metaclass object is the first argument to the function, so we can do \f(CW\*(C`my\ $meta\ =\ shift;\*(C'\fR. .PP See the Moose::Exporter docs for more details on its API. .SH "USING MyApp::Mooseish" .IX Header "USING MyApp::Mooseish" The purpose of all this code is to provide a Moose-like interface. Here's what it would look like in actual use: .PP .Vb 1 \& package MyApp::User; \& \& use namespace::autoclean; \& \& use Moose; \& use MyApp::Mooseish; \& \& has_table \*(AqUser\*(Aq; \& \& has \*(Aqusername\*(Aq => ( is => \*(Aqro\*(Aq ); \& has \*(Aqpassword\*(Aq => ( is => \*(Aqro\*(Aq ); \& \& sub login { ... } .Ve .SH CONCLUSION .IX Header "CONCLUSION" Providing sugar functions can make your extension look much more Moose-ish. See Fey::ORM for a more extensive example. .SH AUTHORS .IX Header "AUTHORS" .IP \(bu 4 Stevan Little .IP \(bu 4 Dave Rolsky .IP \(bu 4 Jesse Luehrs .IP \(bu 4 Shawn M Moore .IP \(bu 4 יובל קוג'מן (Yuval Kogman) .IP \(bu 4 Karen Etheridge .IP \(bu 4 Florian Ragwitz .IP \(bu 4 Hans Dieter Pearcey .IP \(bu 4 Chris Prather .IP \(bu 4 Matt S Trout .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2006 by Infinity Interactive, Inc. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
