DESCRIPTION

Mojo::ByteStream provides portable text and bytestream manipulation functions.

ATTRIBUTES

Mojo::ByteStream implements the following attributes.

raw_size

    my $size = $stream->raw_size;
    $stream  = $stream->raw_size(23);

Raw bytestream size in bytes.

METHODS

Mojo::ByteStream inherits all methods from Mojo::Base and implements the following new ones.

new

    my $stream = Mojo::ByteStream->new($string);

Construct a new Mojo::ByteStream object.

add_chunk

    $stream = $stream->add_chunk('foo');

Add chunk of data to bytestream.

b64_decode

    $stream = $stream->b64_decode;

Base 64 decode bytestream.

b64_encode

    $stream = $stream->b64_encode;
    $stream = $stream->b64_encode('');

Base 64 encode bytestream.

camelize

    $stream = $stream->camelize;

Camelize bytestream.

    foo_bar -> FooBar

clone

    my $stream2 = $stream->clone;

Clone bytestream.

contains

    my $position = $stream->contains('something');

Check if bytestream contains a specific string.

decamelize

    $stream = $stream->decamelize;

Decamelize bytestream.

    FooBar -> foo_bar

decode

    $stream = $stream->decode($encoding);

Decode bytestream.

    $stream->decode('UTF-8')->to_string;

empty

    my $chunk = $stream->empty;

    $stream = $stream->hmac_md5_sum($secret);

Turn bytestream into HMAC-MD5 checksum of old content.

hmac_sha1_sum

    $stream = $stream->hmac_sha1_sum($secret);

md5_sum

    $stream = $stream->md5_sum;

Turn bytestream into MD5 checksum of old content.

punycode_decode

    $stream = $stream->punycode_decode;

    $stream = $stream->qp_decode;

Quoted Printable decode bytestream.

qp_encode

    $stream = $stream->qp_encode;

Quoted Printable encode bytestream.

quote

    $stream = $stream->quote;

Quote bytestream.

remove

    my $chunk = $stream->remove(4);
    my $chunk = $stream->remove(4, 'abcd');

Remove a specific number of bytes from bytestream.

say

    $stream->say;
    $stream->say(*STDERR);

Print bytestream to handle or STDOUT and append a newline.

sha1_bytes

    $stream = $stream->sha1_bytes;

sha1_sum

    $stream = $stream->sha1_sum;

Turn bytestream into SHA1 checksum of old content. Note that Perl 5.10 or Digest::SHA are required for SHA1 support.

size

    my $size = $stream->size;

Size of bytestream.

to_string

    my $string = $stream->to_string;
