.SH DESCRIPTION
.IX Header "DESCRIPTION"
This recipe expands on the use of Moose::Exporter we saw in
Moose::Cookbook::Extending::ExtensionOverview and the class metaclass trait
we saw in Moose::Cookbook::Meta::Table_MetaclassTrait. 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\*(Aqs 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\*(Aqs 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.
