.SH "NAME"
MooX::late \- easily translate Moose code to Moo
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 4
\&   package Foo;
\&   use Moo;
\&   use MooX::late;
\&   has bar => (is => "ro", isa => "Str", default => "MacLaren\*(Aqs Pub");
.Ve
.PP
(Examples for Moo roles in section below.)
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Moo is a light-weight object oriented programming framework which aims
to be compatible with Moose. It does this by detecting when Moose has
been loaded, and automatically \*(L"inflating\*(R" its classes and roles to full
Moose classes and roles. This way, Moo classes can consume Moose roles,
Moose classes can extend Moo classes, and so forth.
.PP
However, the surface syntax of Moo differs somewhat from Moose. For example
the \f(CW\*(C`isa\*(C'\fR option when defining attributes in Moose must be either a string
or a blessed Moose::Meta::TypeConstraint object; but in Moo must be a
coderef. These differences in surface syntax make porting code from Moose to
Moo potentially tricky. MooX::late provides some assistance by enabling a
slightly more Moosey surface syntax.
.PP
MooX::late does the following:
.IP "1." 4
Supports \f(CW\*(C`isa => $stringytype\*(C'\fR.
.IP "2." 4
Supports \f(CW\*(C`does => $rolename\*(C'\fR .
.IP "3." 4
Supports \f(CW\*(C`lazy_build => 1\*(C'\fR.
.IP "4." 4
Exports \f(CW\*(C`blessed\*(C'\fR and \f(CW\*(C`confess\*(C'\fR functions to your namespace.
.IP "5." 4
Handles certain attribute traits. Currently \f(CW\*(C`Hash\*(C'\fR, \f(CW\*(C`Array\*(C'\fR and \f(CW\*(C`Code\*(C'\fR
are supported. This feature requires MooX::HandlesVia.
.Sp
\&\f(CW\*(C`String\*(C'\fR, \f(CW\*(C`Number\*(C'\fR, \f(CW\*(C`Counter\*(C'\fR and \f(CW\*(C`Bool\*(C'\fR are unlikely to ever be
supported because of internal implementation details of Moo. If you need
another attribute trait to be supported, let me know and I will consider
it.
.PP
Five features. It is not the aim of \f(CW\*(C`MooX::late\*(C'\fR to make every aspect of
Moo behave exactly identically to Moose. It's just going after the low-hanging
fruit. So it does five things right now, and I promise that future versions
will never do more than seven.
.PP
Previous releases of MooX::late added support for \f(CW\*(C`coerce => 1\*(C'\fR and
\&\f(CW\*(C`default => $nonref\*(C'\fR. These features have now been added to Moo itself,
so MooX::late no longer has to deal with them.
.SS "Use in Moo::Roles"
.IX Subsection "Use in Moo::Roles"
MooX::late should work in Moo::Roles, with no particular caveats.
.PP
.Vb 3
\&   package MyRole;
\&   use Moo::Role;
\&   use MooX::late;
.Ve
.PP
Package::Variant can be used to build the Moo equivalent of
parameterized roles. MooX::late should work in roles built with
Package::Variant.
.PP
.Vb 3
\&   use Package::Variant
\&      importing => [ qw( Moo::Role MooX::late ) ],
\&      subs      => [ qw( has with ) ];
.Ve
.SS "Type constraints"
.IX Subsection "Type constraints"
Type constraint strings are interpreted using Type::Parser, using the
type constraints defined in Types::Standard. This provides a very slight
superset of Moose's type constraint syntax and built-in type constraints.
.PP
Any unrecognized string that looks like it might be a class name is
interpreted as a class type constraint.
.SS "Subclassing"
.IX Subsection "Subclassing"
MooX::late is designed to be reasonably easy to subclass. There are comments
in the source code explaining hooks for extensibility.
.SH "BUGS"
.IX Header "BUGS"
Please report any bugs to
<http://rt.cpan.org/Dist/Display.html?Queue=MooX\-late>.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
\&\f(CW\*(C`MooX::late\*(C'\fR uses Types::Standard to check type constraints.
.PP
\&\f(CW\*(C`MooX::late\*(C'\fR uses MooX::HandlesVia to provide native attribute traits
support.
.PP
The following modules bring additional Moose functionality to Moo:
.IP "\(bu" 4
MooX::Override \- support override/super
.IP "\(bu" 4
MooX::Augment \- support augment/inner
.PP
MooX allows you to load Moo plus multiple MooX extension modules in a
single line.
