5.1 Public Interface


5.1.1 Special variables

Special Variable: *binary-key-p*

When decoding dictionary values, this function is passed a list, where the first element is the key of the value. If the dictionary was in turn a dictionary value, that key is the second element of the list, and so on. Should a dictionary be a value in a bencoded list, the corresponding element in the list will be the symbol :list. When the function return a true value, the dictionary value will be binary. Otherwise it will be decoded as a string.

The default function in *binary-key-p* returns true for the "pieces" value in the "info" dictionary. All other values are decoded as strings.

Package

bencode.

Source

dictionary.lisp.


5.1.2 Generic functions

Generic Function: decode (input &key external-format &allow-other-keys)

Decode a bencode object from a stream or sequence.
If input is a flexi-stream, its external-format will be used when decoding strings. If input is a string, all characters must have char-codes that fit in an (unsigned-byte 8). Otherwise, the value of the external-format parameter is used to create a flexi-stream for decoding. The default is UTF-8.

Package

bencode.

Source

decode.lisp.

Methods
Method: decode ((stream flexi-stream) &key &allow-other-keys)
Method: decode ((sequence sequence) &key external-format)
Method: decode ((string string) &key external-format)
Method: decode ((stream stream) &key external-format)
Generic Function: encode (object stream &key external-format &allow-other-keys)

Encode object and write it to stream or, if stream
is nil, use an in-memory stream and return the resulting sequence. The external-format is used when encoding strings. UTF-8 is the default.

Package

bencode.

Source

encode.lisp.

Methods
Method: encode ((sequence array) (stream flexi-stream) &key &allow-other-keys)
Method: encode ((integer integer) (stream flexi-stream) &key &allow-other-keys)
Method: encode ((string string) (stream flexi-stream) &key &allow-other-keys)
Method: encode ((dictionary hash-table) (stream flexi-stream) &key &allow-other-keys)
Method: encode ((list list) (stream flexi-stream) &key &allow-other-keys)
Method: encode (object (stream (eql nil)) &key external-format)
Method: encode (object (stream stream) &key external-format)
