MessagePack implementation for CHICKEN scheme

An implementation of MessagePack for CHICKEN scheme.

API Specification

Primitive pack-family procedures:

(pack-uint PORT value)
(pack-sint PORT value)
(pack-float PORT FLONUM)
(pack-double PORT FLONUM)
(pack-bin PORT BYTE-BLOB)  ; byte-blob
(pack-str PORT STRING)     ; string
(pack-array PORT VECTOR)   ; vector
(pack-map PORT HASH-TABLE) ; hash-table
(pack-ext PORT EXT)        ; extension (see below)

Additionally, this implementation provides a generic pack procedure:

(pack PORT value)

This procedure will call primitive type packers, with the following rules:

• if the value has a packer, apply it.
• if the value is a string, it will be packed as str.
• if the value is a blob, it will be packed as bin.
• if the value is a char, it will be packed as a uint.
• if the value is a list, it will be packed as an array.
• if the value is a extension (see below), it will be packed as an ext

Unpack procedures:

(unpack PORT [mapper])

Extension

Extension is record defined as:

- type: integer from 0 to 127
- data: a byte-blob

(define-record extension type data)

Example:

(make-extension 10 (string->byte-blob "hi"))
