=head1 NAME
Mojo::Path - Path
=head1 SYNOPSIS
use Mojo::Path;
# Parse
my $path = Mojo::Path->new('/foo%2Fbar%3B/baz.html');
say $path->[0];
# Build
my $path = Mojo::Path->new('/i/♥');
push @$path, 'mojolicious';
say "$path";
=head1 DESCRIPTION
L<Mojo::Path> is a container for paths used by L<Mojo::URL> and based on
L<RFC 3986|http://tools.ietf.org/html/rfc3986>.
=head1 ATTRIBUTES
L<Mojo::Path> implements the following attributes.
=head2 charset
my $charset = $path->charset;
$path = $path->charset('UTF-8');
Charset used for encoding and decoding, defaults to C<UTF-8>.
# Disable encoding and decoding
$path->charset(undef);
=head1 METHODS
L<Mojo::Path> inherits all methods from L<Mojo::Base> and implements the
following new ones.
=head2 canonicalize
$path = $path->canonicalize;
Canonicalize path.
# "/foo/baz"
Mojo::Path->new('/foo/./bar/../baz')->canonicalize;
# "/../baz"
Mojo::Path->new('/foo/../bar/../../baz')->canonicalize;
=head2 clone
my $clone = $path->clone;
Clone path.
=head2 contains
my $bool = $path->contains('/i/♥/mojolicious');
Check if path contains given prefix.
# True
Mojo::Path->new('/foo/bar')->contains('/');
Mojo::Path->new('/foo/bar')->contains('/foo');
Mojo::Path->new('/foo/bar')->contains('/foo/bar');
# False
Mojo::Path->new('/foo/bar')->contains('/f');
Mojo::Path->new('/foo/bar')->contains('/bar');
Mojo::Path->new('/foo/bar')->contains('/whatever');
=head2 leading_slash
my $bool = $path->leading_slash;
$path = $path->leading_slash($bool);
Path has a leading slash. Note that this method will normalize the path and
that C<%2F> will be treated as C</> for security reasons.
=head2 merge
$path = $path->merge('/foo/bar');
$path = $path->merge('foo/bar');
$path = $path->merge(Mojo::Path->new('foo/bar'));
Merge paths. Note that this method will normalize both paths if necessary and
that C<%2F> will be treated as C</> for security reasons.
# "/baz/yada"
Mojo::Path->new('/foo/bar')->merge('/baz/yada');
# "/foo/baz/yada"
Mojo::Path->new('/foo/bar')->merge('baz/yada');
# "/foo/bar/baz/yada"
Mojo::Path->new('/foo/bar/')->merge('baz/yada');
=head2 new
my $path = Mojo::Path->new;
my $path = Mojo::Path->new('/foo%2Fbar%3B/baz.html');
Construct a new L<Mojo::Path> object and L</"parse"> path if necessary.
=head2 parse
$path = $path->parse('/foo%2Fbar%3B/baz.html');
Parse path.
=head2 to_abs_string
my $str = $path->to_abs_string;
Turn path into an absolute string.
# "/i/%E2%99%A5/mojolicious"
Mojo::Path->new('/i/%E2%99%A5/mojolicious')->to_abs_string;
Mojo::Path->new('i/%E2%99%A5/mojolicious')->to_abs_string;
=head2 parts
my $parts = $path->parts;
$path = $path->parts([qw(foo bar baz)]);
The path parts. Note that this method will normalize the path and that C<%2F>
will be treated as C</> for security reasons.
# Part with slash
push @{$path->parts}, 'foo/bar';
=head2 to_dir
my $dir = $route->to_dir;
Clone path and remove everything after the right-most slash.
# "/i/%E2%99%A5/"
Mojo::Path->new('/i/%E2%99%A5/mojolicious')->to_dir->to_abs_string;
# "i/%E2%99%A5/"
Mojo::Path->new('i/%E2%99%A5/mojolicious')->to_dir->to_abs_string;
=head2 to_route
my $route = $path->to_route;
Turn path into a route.
# "/i/♥/mojolicious"
Mojo::Path->new('/i/%E2%99%A5/mojolicious')->to_route;
Mojo::Path->new('i/%E2%99%A5/mojolicious')->to_route;
=head2 to_string
my $str = $path->to_string;
Turn path into a string.
# "/i/%E2%99%A5/mojolicious"
Mojo::Path->new('/i/%E2%99%A5/mojolicious')->to_string;
# "i/%E2%99%A5/mojolicious"
Mojo::Path->new('i/%E2%99%A5/mojolicious')->to_string;
=head2 trailing_slash
my $bool = $path->trailing_slash;
$path = $path->trailing_slash($bool);
Path has a trailing slash. Note that this method will normalize the path and
that C<%2F> will be treated as C</> for security reasons.
=head1 OPERATORS
L<Mojo::Path> overloads the following operators.
=head2 array
my @parts = @$path;
Alias for L</"parts">. Note that this will normalize the path and that C<%2F>
will be treated as C</> for security reasons.
say $path->[0];
say for @$path;
=head2 bool
my $bool = !!$path;
Always true.
=head2 stringify
my $str = "$path";
Alias for L</"to_string">.
=head1 SEE ALSO
