Type::Tiny::Manual - an overview of Type::Tiny
Type::Tiny is bundled with Type::Library a framework for organizing type constraints into collections.
Also bundled is Types::Standard, a Moose-inspired library of useful type constraints.
Type::Params is also provided, to allow very fast checking and coercion of function and method parameters.
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.
At run-time, Type::Tiny requires the following modules: B, B::Deparse, Data::Dumper, Scalar::Util, Text::Balanced, base, 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.
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
so you do not need to install them separately.
Perl 5.6.x support is not well tested; if it proves too burdensome to maintain, it may be dropped in a future release.
Type::Tiny is similar in aim to Specio. The major differences are
Type::Tiny is faster and supports coercions.
Scalar::Does is somewhat of a precursor to Type::Tiny, but has now been rewritten to use Type::Tiny internally.
It gives you a
$type) function that is roughly equivalent to
$type->check($value) except that
$type may be one of a list of pre-defined strings (instead of a Type::Tiny type constraint); or may be a package name in which case it will be assumed to be a role and checked with
Please report any bugs to http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny.
IRC: support is available through in the #moose channel on irc.perl.org. If Type::Tiny discussion there becomes overwhelming (unlikely) then I'll move it to a separate channel.
