fcl-json - a JSON (Javascript Object Notation) implementation
Notes
Contains the fpjson JSON manipulation unit.
Note: In FPJSON, accessing e.g. SomeJSONObject.Integers['price'] may give a SIGSEGV/Access Violation if that integer variable does not exist. This is apparently intentional, see [1]
You'd have to use the .Find method (available since FPC 2.6.2) to first check if the element/variable (price in this example) exists.
Streaming
fcl-json contains the unit fpjsonrtti which is used to load objects from or save them to JSON format.
See Streaming JSON (english) | Streaming JSON/de (german) for a short example.
Examples
Example usage can be found in the Lazarus jsonviewer tool.
Also, the fpctwit library makes use of JSON to send/receive data.
