Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

Description

This extension implements a parser and generator for the JSON data interchange format.

See also json-abnf and medea.

API

json-write OBJECT #!optional PORTprocedure

Writes the Scheme data object OBJECT in JSON format to PORT which defaults to the value of (current-output-port). Scheme data is mapped to JSON format in the following way:

SchemeJSON
Hash-tableStructure
VectorStructure (assuming vector consists of (SYMBOL . DATA) pairs
ListArray
NumberNumber
VoidNull
String or symbolString
json-read #!optional PORTprocedure

Reads data in JSON format from PORT which defaults to the value of (current-input-port).

Note that json-read does not produce alists, as the result are vectors and not lists, and keys are strings and not symbols.
