This is a port of the original Jansson library by Petri Lehtinin which is
available at http://www.digip.org/jansson/. This is the current latest
version, 2.12, and was made using my libgen program with a bit of tweaking.
This reupload fixes a typo in the return type for json_object_get () which
was incorrevtly set to "json_t" rather than "json_t *".

This port is as a dynamically-loaded shared library (.library) as opposed to
dynamically-linked shared object (.so), which already has a port of version
2.7 previously ported by Fredrik Wikstrom and is available at

As a standard library, its interface is IJansson and all of its functions
match the standard jannson functions. For instance,

	* IJannson->json_object_set_new () is the matching function for
          json_object_set_new ()
	* IJansson->json_dumps () is the matching function for json_dumps ()


There are *no* inline function defines as they would have a nameclash with the
actual jansson function names.

The include/jansson directory contains the original jansson header files with
some minor tweaks for compatibility.

If you wish to test it prior to installing, there is a small test program and
its source code included in the archive which can be compiled using

	gcc amiga_test.c -o amiga_test -Wall -O3 -Iinclude -Iinclude/jansson

To run it, you'll need to add the jansson library to the library search path
which you can do with

	assign libs: lib/ add

Then you can run it by typing


which should give output similar to

json: {"string_key": "string_value"}
loaded json is equal to saved json
packed successfully:
    "key": 4,
    "my": {
      "nested": "value",
      "boolean false": false
    "real pi": 3.1415920000000002
results: [3/3] tests ran successfully
