% cpanm Type::Tiny
If you are installing into a system-wide directory, you may need to pass the ``-S'' flag to cpanm, which uses sudo to install the module:
% cpanm -S Type::Tiny
% cpan Type::Tiny
Consult the file META.json for a list of pre-requisites. Install these first.
To build Type-Tiny:
% perl Makefile.PL % make && make test
Then install it:
% make install
If you are installing into a system-wide directory, you may need to run:
% sudo make install
Type::Tiny requires Exporter::Tiny, a module that was previously bundled in this distribution, but has since been spun off as a separate distribution. Don't worry - it's quick and easy to install.
At run-time, Type::Tiny also requires the following Perl modules: B, B::Deparse, Carp, Data::Dumper, Scalar::Util, Text::Balanced, overload, strict, and warnings. All of these come bundled with Perl itself.
Certain features require additional modules. Stack traces on exceptions require Devel::StackTrace. The Reply::Plugin::TypeTiny plugin for Reply requires Reply (obviously).
Type::Tiny::XS is not required, but if available provides a speed boost for some type checks. (Setting the environment variable "PERL_TYPE_TINY_XS" to false, or setting "PERL_ONLY" to true will suppress the use of Type::Tiny::XS, even if it is available.)
The test suite additionally requires Test::More, Test::Fatal and Test::Requires. Test::More comes bundled with Perl, but if you are using a version of Perl older than 5.14, you will need to upgrade to at least Test::More version 0.96. Test::Requires and Test::Fatal (plus Try::Tiny which Test::Fatal depends on) are bundled with Type::Tiny in the "inc" directory, so you do not need to install them separately.
If using Type::Tiny in conjunction with Moo, then at least Moo 1.006000 is recommended. If using Type::Tiny with Moose, then at least Moose 2.0000 is recommended. If using Type::Tiny with Mouse, then at least Mouse 1.00 is recommended. Type::Tiny is mostly untested against older versions of these packages.
Type::Tiny and cperl
cperl <http://perl11.org/cperl/> is an extended version of Perl with various incompatible changes from the official Perl 5 releases.
As of Type::Tiny 1.010001, cperl is a supported platform for Type::Tiny with some caveats. At the time of writing, Moose will not install on the latest cperl releases, so using Type::Tiny with Moose on cperl is untested. Moo can be forced to install, and Type::Tiny is verified to work with Moo on cperl. cperl not only enables a new warnings category called ``shadow'' (which is good; they're potentially useful) but switches on shadow warnings by default (which is annoying). Type::Tiny does not (and likely will never) attempt to work around these warnings. If the warnings bother you, you should be able to catch them using $SIG{__WARN__}. Certain features of Eval::TypeTiny are broken under cperl, but they're not thought to have any practical effect on Type::Tiny or its other bundled modules.
Basic use of Type::Tiny with Moo, including attribute type constraints, parameterized type constraints, coercions, and method parameter checking.
