NAME

HTTP::Promise::Stream::UU - Stream Encoder for UU Encoding

SYNOPSIS

    use HTTP::Promise::Stream::UU;
    my $s = HTTP::Promise::Stream::UU->new || 
        die( HTTP::Promise::Stream::UU->error, "\n" );
    $s->encode( $input => $output, eol => "\n" ) ||
        die( $s->error );
    $s->decode( $input => $output ) || die( $s->error );
    HTTP::Promise::Stream::UU::encode_uu( $input => $output, eol => "\n" ) ||
        die( $HTTP::Promise::Stream::UU::UUError );
    HTTP::Promise::Stream::UU::decode_uu( $input => $output, eol => "\n" ) ||
        die( $HTTP::Promise::Stream::UU::UUError );

VERSION

    v0.1.0

DESCRIPTION

This implements an encoding and decoding mechanism for UU encoding using either of the following on input and output:

filepath

If the parameter is neither a scalar reference nor a file handle, it will be assumed to be a file path.

file handle

This can be a native file handle, or an object oriented one as long as it implements the print or write, and read methods. The read method is expected to return the number of bytes read or undef upon error. The print and write methods are expected to simply return true upon success and undef upon error.

Alternatively, those methods can die and those exceptions wil be caught.

scalar reference

This can be a simple scalar reference, or an object scalar reference.

CONSTRUCTOR

new

Creates a new HTTP::Promise::Stream::UU object and returns it.

METHODS

decode

This takes 2 arguments: an input and an output. Each one can be either a file path, a file handle, or a scalar reference.

It will decode the UU encoded data and write the result into the output.

It returns true upon success and sets an error and return undef upon error.

encode

This takes 2 arguments: an input and an output. Each one can be either a file path, a file handle, or a scalar reference.

It will encode the data into UU encoded data and write the result into the output.

Possible options are:

filename

The file name (not the file path) to be used for UU encoding.

mode

The file octal permisions, like 0644. It defaults to 0644 if nothing is provided.

It returns true upon success and sets an error and return undef upon error.

CLASS FUNCTIONS

The following class functions are available and can also be exported, such as:

    use HTTP::Promise::Stream::Brotli qw( decode_uu encode_uu );

decode_uu

This takes the same 2 arguments used in "decode": an input and an output. Each one can be either a file path, a file handle, or a scalar reference.

It will decode the UU encoded data and write the result into the output.

It returns true upon success, and upon error, it will set the error in the global variable $UUError and return undef

    my $decoded = HTTP::Promise::Stream::UU::decode_uu( $encoded );
    die( "Something went wrong: $HTTP::Promise::Stream::UU::UUError\n" if( !defined( $decoded ) );
    print( "Decoded data is: $decoded\n" );

encode_uu

This takes the same 2 arguments used in "encode": an input and an output. Each one can be either a file path, a file handle, or a scalar reference.

It will encode the data into UU encoded data and write the result into the output.

It returns true upon success, and upon error, it will set the error in the global variable $UUError and return undef

    my $encoded = HTTP::Promise::Stream::UU::encode_uu( $data );
    die( "Something went wrong: $HTTP::Promise::Stream::UU::UUError\n" if( !defined( $encoded ) );
    print( "Encoded data is: $encoded\n" );
