NAME

Venus::Regexp - Regexp Class

ABSTRACT

Regexp Class for Perl 5

SYNOPSIS

  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new(
    qr/(?<greet>\w+) (?<username>\w+)/u,
  );

  # $regexp->search;

DESCRIPTION

This package provides methods for manipulating regexp data.

INHERITS

This package inherits behaviors from:

Venus::Kind::Value

METHODS

This package provides the following methods:

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

cast example 1
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('array');

  # bless({ value => [qr/(?^u:)/] }, "Venus::Array")
cast example 2
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('boolean');

  # bless({ value => 1 }, "Venus::Boolean")
cast example 3
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('code');

  # bless({ value => sub { ... } }, "Venus::Code")
cast example 4
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('float');

  # bless({ value => "1.0" }, "Venus::Float")
cast example 5
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('hash');

  # bless({ value => { "0" => qr/(?^u:)/ } }, "Venus::Hash")
cast example 6
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('number');

  # bless({ value => 5 }, "Venus::Number")
cast example 7
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('regexp');

  # bless({ value => qr/(?^u:)/ }, "Venus::Regexp")
cast example 8
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('scalar');

  # bless({ value => \qr/(?^u:)/ }, "Venus::Scalar")
cast example 9
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('string');

  # bless({ value => "qr//u" }, "Venus::String")
cast example 10
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new;

  my $cast = $regexp->cast('undef');

  # bless({ value => undef }, "Venus::Undef")

numified

  numified() (Int)

The numified method returns the numerical representation of the object. For regexp objects the method returns the length (or character count) of the stringified object.

Since 0.08

numified example 1
  # given: synopsis;

  my $numified = $regexp->numified;

  # 36
numified example 2

    qr/.*/u,
  );

  my $numified = $regexp->numified;

  # 7

replace

  replace(Str $string, Str $substr, Str $flags) (Replace)

The replace method performs a regular expression substitution on the given string. The first argument is the string to match against. The second argument is the replacement string. The optional third argument might be a string representing flags to append to the s///x operator, such as 'g' or 'e'. This method will always return a Venus::Replace object which can be used to introspect the result of the operation.

Since 0.01

replace example 1
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new(
    qr/(?<username>\w+)$/,
  );

  my $replace = $regexp->replace('Hey, unknown', 'awncorp');

  # bless({ ... }, 'Venus::Replace')
  search(Str $string) (Search)

The search method performs a regular expression match against the given string, this method will always return a Venus::Search object which can be used to introspect the result of the operation.

Since 0.01

search example 1
  package main;

  use Venus::Regexp;

  my $regexp = Venus::Regexp->new(
    qr/(?<greet>\w+), (?<username>\w+)/,
  );

  my $search = $regexp->search('hey, awncorp');

  # bless({ ... }, 'Venus::Search')

stringified

  stringified() (Str)

The stringified method returns the object, stringified (i.e. a dump of the object's value).

Since 0.08
