.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'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 \s-1API.\s0
.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.
