# NAME MooseX::StrictConstructor - Make your object constructors blow up on unknown attributes # VERSION version 0.21 # SYNOPSIS package My::Class; use Moose; use MooseX::StrictConstructor; has 'size' => ( is => 'ro' ); # then later ... # this blows up because color is not a known attribute My::Class->new( size => 5, color => 'blue' ); # DESCRIPTION Simply loading this module makes your constructors "strict". If your constructor is called with an attribute init argument that your class does not declare, then it calls `Moose->throw_error()`. This is a great way to catch small typos. ## Subverting Strictness You may find yourself wanting to have your constructor accept a parameter which does not correspond to an attribute. In that case, you'll probably also be writing a `BUILD()` or `BUILDARGS()` method to deal with that parameter. In a `BUILDARGS()` method, you can simply make sure that this parameter is not included in the hash reference you return. Otherwise, in a `BUILD()` method, you can delete it from the hash reference of parameters. sub BUILD { my $self = shift; my $params = shift; if ( delete $params->{do_something} ) { ... } } # BUGS Please report any bugs or feature requests to `bug-moosex-strictconstructor@rt.cpan.org`, or through the web interface at [http://rt.cpan.org](http://rt.cpan.org). I will be notified, and then you'll automatically be notified of progress on your bug as I make changes. Bugs may be submitted at [https://github.com/moose/MooseX-StrictConstructor/issues](https://github.com/moose/MooseX-StrictConstructor/issues). I am also usually active on IRC as 'autarch' on `irc://irc.perl.org`. # SOURCE The source code repository for MooseX-StrictConstructor can be found at [https://github.com/moose/MooseX-StrictConstructor](https://github.com/moose/MooseX-StrictConstructor). # DONATIONS If you'd like to thank me for the work I've done on this module, please consider making a "donation" to me via PayPal. I spend a lot of free time creating free software, and would appreciate any support you'd care to offer. Please note that **I am not suggesting that you must do this** in order for me to continue working on this particular software. I will continue to do so, inasmuch as I have in the past, for as long as it interests me. Similarly, a donation made in this way will probably not make me work on this software much more, unless I get so many donations that I can consider working on free software full time (let's all have a chuckle at that together). To donate, log into PayPal and send money to autarch@urth.org, or use the button at [http://www.urth.org/~autarch/fs-donation.html](http://www.urth.org/~autarch/fs-donation.html). # AUTHOR Dave Rolsky # CONTRIBUTORS - Jesse Luehrs - Karen Etheridge - Ricardo Signes # COPYRIGHT AND LICENSE This software is Copyright (c) 2007 - 2017 by Dave Rolsky.
