=head1 NAME
Mojo::ByteStream - ByteStream
=head1 SYNOPSIS
# Manipulate bytestreams
use Mojo::ByteStream;
my $stream = Mojo::ByteStream->new('foo_bar_baz');
say $stream->camelize;
# Chain methods
my $stream = Mojo::ByteStream->new('foo bar baz')->quote;
$stream = $stream->unquote->encode('UTF-8')->b64_encode;
say $stream;
# Use the alternative constructor
use Mojo::ByteStream 'b';
my $stream = b('foobarbaz')->html_escape;
=head1 DESCRIPTION
L<Mojo::ByteStream> provides a more friendly API for the bytestream
manipulation functions in L<Mojo::Util>.
=head1 METHODS
L<Mojo::ByteStream> inherits all methods from L<Mojo::Base> and implements
the following new ones.
=head2 C<new>
my $stream = Mojo::ByteStream->new('test123');
Construct a new L<Mojo::ByteStream> object.
=head2 C<b64_decode>
$stream = $stream->b64_decode;
Base64 decode bytestream.
=head2 C<b64_encode>
$stream = $stream->b64_encode;
$stream = $stream->b64_encode('');
Base64 encode bytestream.
=head2 C<camelize>
$stream = $stream->camelize;
Convert snake case bytestream to camel case and replace C<-> with C<::>.
foo_bar -> FooBar
foo_bar-baz -> FooBar::Baz
=head2 C<clone>
my $stream2 = $stream->clone;
Clone bytestream.
=head2 C<decamelize>
$stream = $stream->decamelize;
Convert camel case bytestream to snake case and replace C<::> with C<->.
FooBar -> foo_bar
FooBar::Baz -> foo_bar-baz
=head2 C<decode>
$stream = $stream->decode;
$stream = $stream->decode($encoding);
Decode bytestream, defaults to C<UTF-8>.
$stream->decode('UTF-8')->to_string;
=head2 C<encode>
$stream = $stream->encode;
$stream = $stream->encode($encoding);
Encode bytestream, defaults to C<UTF-8>.
$stream->encode('UTF-8')->to_string;
=head2 C<hmac_md5_sum>
$stream = $stream->hmac_md5_sum($secret);
Turn bytestream into HMAC-MD5 checksum of old content.
=head2 C<hmac_sha1_sum>
$stream = $stream->hmac_sha1_sum($secret);
Turn bytestream into HMAC-SHA1 checksum of old content.
=head2 C<html_escape>
$stream = $stream->html_escape;
HTML escape bytestream.
=head2 C<html_unescape>
$stream = $stream->html_unescape;
HTML unescape bytestream.
=head2 C<md5_bytes>
$stream = $stream->md5_bytes;
Turn bytestream into binary MD5 checksum of old content.
=head2 C<md5_sum>
$stream = $stream->md5_sum;
Turn bytestream into MD5 checksum of old content.
=head2 C<punycode_decode>
$stream = $stream->punycode_decode;
Punycode decode bytestream.
=head2 C<punycode_encode>
$stream = $stream->punycode_encode;
Punycode encode bytestream.
=head2 C<qp_decode>
$stream = $stream->qp_decode;
Quoted Printable decode bytestream.
=head2 C<qp_encode>
$stream = $stream->qp_encode;
Quoted Printable encode bytestream.
=head2 C<quote>
$stream = $stream->quote;
Quote bytestream.
=head2 C<say>
$stream->say;
$stream->say(*STDERR);
Print bytestream to handle or STDOUT and append a newline.
=head2 C<secure_compare>
my $success = $stream->secure_compare($string);
Constant time comparison algorithm to prevent timing attacks.
=head2 C<sha1_bytes>
$stream = $stream->sha1_bytes;
Turn bytestream into binary SHA1 checksum of old content.
=head2 C<sha1_sum>
$stream = $stream->sha1_sum;
Turn bytestream into SHA1 checksum of old content.
=head2 C<size>
my $size = $stream->size;
Size of bytestream.
=head2 C<split>
my $collection = $stream->split(',');
Turn bytestream into L<Mojo::Collection>.
Note that this method is EXPERIMENTAL and might change without warning!
$stream->split(',')->map(sub { $_->quote })->join("\n")->say;
=head2 C<to_string>
my $string = $stream->to_string;
Stringify bytestream.
=head2 C<trim>
$stream = $stream->trim;
Trim whitespace characters from both ends of bytestream.
=head2 C<unquote>
$stream = $stream->unquote;
Unquote bytestream.
=head2 C<url_escape>
$stream = $stream->url_escape;
$stream = $stream->url_escape('A-Za-z0-9\-\.\_\~');
URL escape bytestream.
=head2 C<url_unescape>
$stream = $stream->url_unescape;
URL unescape bytestream.
=head2 C<xml_escape>
$stream = $stream->xml_escape;
XML escape bytestream, this is a much faster version of C<html_escape>
escaping only the characters C<&>, C<E<lt>>, C<E<gt>>, C<"> and C<'>.
