=head1 NAME

Types::Common::String - drop-in replacement for MooseX::Types::Common::String

=head1 STATUS

This module is covered by the
L<Type-Tiny stability policy|Type::Tiny::Manual::Policies/"STABILITY">.

=head1 DESCRIPTION

A drop-in replacement for L<MooseX::Types::Common::String>.

=head2 Types

The following types are similar to those described in
L<MooseX::Types::Common::String>.

=over

=item *

B<SimpleStr>

=item *

B<NonEmptySimpleStr>

=item *

B<NumericCode>

=item *

B<LowerCaseSimpleStr>

=item *

B<UpperCaseSimpleStr>

=item *

B<Password>

=item *

B<StrongPassword>

=item *

B<NonEmptyStr>

=item *

B<LowerCaseStr>

=item *

B<UpperCaseStr>

=back

This module also defines some extra type constraints not found in
L<MooseX::Types::Common::String>.

=over

=item *

B<< StrLength[`min, `max] >>

Type constraint for a string between min and max characters long. For
example:

  StrLength[4, 20]

It is sometimes useful to combine this with another type constraint in an
intersection.

  (LowerCaseStr) & (StrLength[4, 20])

The max length can be omitted.

  StrLength[10]   # at least 10 characters

Lengths are inclusive.

=item *

B<< DelimitedStr[`delimiter, `type, `min, `max, `ws] >>

Parameterized constraint for delimited strings, such as comma-delimited.

B<< DelimitedStr[",", Int, 1, 3] >> will allow between 1 and 3 integers,
separated by commas. So C<< "1,42,-999" >> will pass the type constraint,
but C<< "Hello,45" >> will fail.

The ws parameter allows optional whitespace surrounding the delimiters,
as well as optional leading and trailing whitespace.

The type, min, max, and ws parameters are optional.

Parameterized B<DelimitedStr> type constraints will automatically have a
coercion from B<< ArrayRef[`type] >> which uses C<< join >> to join by the
delimiter. The plain unparameterized type constraint B<DelimitedStr> has
a coercion from B<< ArrayRef[Str] >> which joins the strings using the
list separator C<< $" >> (which is a space by default).
