Type::Tiny::Manual::Installation - how to install Type::Tiny
Installing Type-Tiny should be straightforward.
If you have cpanm, you only need one line:
% 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
Alternatively, if your CPAN shell is set up, you should just be able to do:
% cpan Type::Tiny
As a last resort, you can manually install it. Download the tarball and unpack it.
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 at least Perl 5.6.1, though certain Unicode-related features (e.g. non-ASCII type constraint names) may work better in newer versions of Perl.
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 modules: B, B::Deparse, Carp, Data::Dumper, Scalar::Util, Text::Balanced, overload, strict and warnings. All of these come bundled with Perl itself. Prior to Perl 5.8, Scalar::Util and Text::Balanced do not come bundled with Perl and will need installing separately from the CPAN.
Certain features require additional modules. Tying a variable to a type constraint (e.g. tie my $count, Int) requires Type::Tie; stack traces on exceptions require Devel::StackTrace. The Reply::Plugin::TypeTiny plugin for Reply requires Reply (obviously). Devel::LexAlias may slightly increase the speed of some of Type::Tiny's compiled coderefs.
tie my $count, Int
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.)
PERL_TYPE_TINY_XS
PERL_ONLY
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.
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.
$SIG{__WARN__}
