DESCRIPTION

This package provides methods for manipulating string data.

INHERITS

This package inherits behaviors from:

Venus::Kind::Value

METHODS

This package provides the following methods:

append

append(Str @parts) (Str)

The append method appends arugments to the string using spaces.

Since 0.01

append example 1
# given: synopsis;

my $append = $string->append('welcome');

# "hello world welcome"

append_with

append_with(Str $delimiter, Str @parts) (Str)

The append_with method appends arugments to the string using the delimiter provided.

Since 0.01

append_with example 1
# given: synopsis;

my $append = $string->append_with(', ', 'welcome');

# "hello world, welcome"

camelcase

camelcase() (Str)

The camelcase method converts the string to camelcase.

Since 0.01

camelcase example 1
# given: synopsis;

my $camelcase = $string->camelcase;

# "helloWorld"

cast

cast(Str $kind) (Object | Undef)

The cast method converts "value" objects between different "value" object types, based on the name of the type provided. This method will return undef if the invocant is not a Venus::Kind::Value.

Since 0.08
