NAME
Type::Tiny::Manual::Installation - how to install Type::Tiny

MANUAL
Installing Type-Tiny should be straightforward.

Installation with cpanminus
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

Installation with the CPAN Shell
Alternatively, if your CPAN shell is set up, you should just be able to do:

% cpan Type::Tiny

Manual Installation
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

Dependencies
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.

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.

type constraints, coercions, and method parameter checking.
