* Other:
- Make it possible to forward declare ``struct json_t``.
Version 2.4
===========
Released 2012-09-23
* New features:
- Add `json_boolean()` macro that returns the JSON true or false
value based on its argument (#86).
- Add `json_load_callback()` that calls a callback function
repeatedly to read the JSON input (#57).

only adding missing keys to an object. (#37)
- Add `json_object_foreach()` for more convenient iteration over
objects. (#45, #46)
- When decoding JSON, write the number of bytes that were read from
input to ``error.position`` also on success. This is handy with

- Add support for decoding any JSON value, not just arrays or
objects. The support is enabled with the new ``JSON_DECODE_ANY``
flag. Patch by Andrea Marchesini. (#4)
* Bug fixes

* New features:
- `json_loadb()`: Decode a string with a given size, useful if the
string is not null terminated.
- Add ``JSON_ENCODE_ANY`` encoding flag to allow encoding any JSON
value. By default, only arrays and objects can be encoded. (#19)
- Add ``JSON_REJECT_DUPLICATES`` decoding flag to issue a decoding
error if any JSON object in the input contins duplicate keys. (#3)

Version 2.0.1
=============
Released 2011-03-31
* Bug fixes:

* Documentation:
- Distribute ``doc/upgrading.rst`` with the source tarball.
- Build documentation in strict mode in ``make distcheck``.
Version 2.0
===========
Released 2011-02-28
This release is backwards incompatible with the 1.x release series.
See the chapter "Upgrading from older versions" in documentation for
details.
* Backwards incompatible changes:
- Unify unsigned integer usage in the API: All occurences of
unsigned int and unsigned long have been replaced with size_t.
- Change JSON integer's underlying type to the widest signed integer
type available, i.e. long long if it's supported, otherwise long.
Add a typedef json_int_t that defines the type.
- Change the maximum indentation depth to 31 spaces in encoder. This
frees up bits from the flags parameter of encoding functions
`json_dumpf()`, `json_dumps()` and `json_dump_file()`.
- For future needs, add a flags parameter to all decoding functions
`json_loadf()`, `json_loads()` and `json_load_file()`.
* New features
- `json_pack()`, `json_pack_ex()`, `json_vpack_ex()`: Create JSON
values based on a format string.
- `json_unpack()`, `json_unpack_ex()`, `json_vunpack_ex()`: Simple
value extraction and validation functionality based on a format
string.
- Add column, position and source fields to the ``json_error_t``
struct.
- Enhance error reporting in the decoder.
- ``JANSSON_VERSION`` et al.: Preprocessor constants that define the
library version.
- `json_set_alloc_funcs()`: Set custom memory allocation functions.
* Fix many portability issues, especially on Windows.
* Configuration
- Add file ``jansson_config.h`` that contains site specific
configuration. It's created automatically by the configure script,
or can be created by hand if the configure script cannot be used.
The file ``jansson_config.h.win32`` can be used without
modifications on Windows systems.
- Add a section to documentation describing how to build Jansson on
Windows.
- Documentation now requires Sphinx 1.0 or newer.
Version 1.3
===========
Released 2010-06-13
* New functions:
- `json_object_iter_set()`, `json_object_iter_set_new()`: Change
object contents while iterating over it.
- `json_object_iter_at()`: Return an iterator that points to a
specific object item.
* New encoding flags:
- ``JSON_PRESERVE_ORDER``: Preserve the insertion order of object
keys.
* Bug fixes:
- Fix an error that occured when an array or object was first
encoded as empty, then populated with some data, and then
re-encoded
- Fix the situation like above, but when the first encoding resulted
in an error
* Documentation:
- Clarify the documentation on reference stealing, providing an
example usage pattern
Version 1.2.1
=============
Released 2010-04-03
* Bug fixes:
- Fix reference counting on ``true``, ``false`` and ``null``
- Estimate real number underflows in decoder with 0.0 instead of
issuing an error

- Add a chapter on RFC conformance
Version 1.2
===========
Released 2010-01-21
* New functions:
- `json_equal()`: Test whether two JSON values are equal
- `json_copy()` and `json_deep_copy()`: Make shallow and deep copies
of JSON values
- Add a version of all functions taking a string argument that
doesn't check for valid UTF-8: `json_string_nocheck()`,
`json_string_set_nocheck()`, `json_object_set_nocheck()`,
`json_object_set_new_nocheck()`
* New encoding flags:
- ``JSON_SORT_KEYS``: Sort objects by key
- ``JSON_ENSURE_ASCII``: Escape all non-ASCII Unicode characters
- ``JSON_COMPACT``: Use a compact representation with all unneeded
whitespace stripped
* Bug fixes:
- Revise and unify whitespace usage in encoder: Add spaces between
array and object items, never append newline to output.
- Remove const qualifier from the ``json_t`` parameter in
`json_string_set()`, `json_integer_set()` and `json_real_set`.
- Use ``int32_t`` internally for representing Unicode code points
(int is not enough on all platforms)
* Other changes:
- Convert ``CHANGES`` (this file) to reStructured text and add it to
HTML documentation
- The test system has been refactored. Python is no longer required
to run the tests.
- Documentation can now be built by invoking ``make html``

# E.g.:
# $(call add-clean-step, touch -c external/sqlite/sqlite3.h)
# $(call add-clean-step, rm -rf $(PRODUCT_OUT)/obj/STATIC_LIBRARIES/libz_intermediates)

Jansson_ is a C library for encoding, decoding and manipulating JSON
data. Its main features and design principles are:
- Simple and intuitive API and data model
- `Comprehensive documentation`_
- No dependencies on other libraries
- Full Unicode support (UTF-8)
- Extensive test suite
Jansson is licensed under the `MIT license`_; see LICENSE in the
source distribution for details.
Compilation and Installation
----------------------------
You can download and install Jansson using the `vcpkg <https://github.com/Microsoft/vcpkg/>`_ dependency manager:
.. code-block:: bash
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
vcpkg install jansson
The Jansson port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please `create an issue or pull request <https://github.com/Microsoft/vcpkg/>`_ on the vcpkg repository.
If you obtained a `source tarball`_ from the "Releases" section of the main
site just use the standard autotools commands::
$ ./configure
$ make
$ make install
To run the test suite, invoke::
$ make check
If the source has been checked out from a Git repository, the
./configure script has to be generated first. The easiest way is to
use autoreconf::
$ autoreconf -i
Documentation
-------------
Documentation is available at http://jansson.readthedocs.io/en/latest/.
The documentation source is in the ``doc/`` subdirectory. To generate
HTML documentation, invoke::
$ make html
Then, point your browser to ``doc/_build/html/index.html``. Sphinx_
1.0 or newer is required to generate the documentation.

# 2012-01-31, Lars Bilke
# - Enable Code Coverage
#
# 2013-09-17, Joakim Söderberg
# - Added support for Clang.
# - Some additional usage instructions.
#
# USAGE:
# 1. Copy this file into your cmake modules path.
#
# 2. Add the following line to your CMakeLists.txt:
# INCLUDE(CodeCoverage)
#
# 3. Set compiler flags to turn off optimization and enable coverage:
# SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
# SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
#
# 3. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target
# which runs your test executable and produces a lcov code coverage report:
# Example:
# SETUP_TARGET_FOR_COVERAGE(
# my_coverage_target # Name for custom target.
# test_driver # Name of the test driver executable that runs the tests.
# # NOTE! This should always have a ZERO as exit code
# # otherwise the coverage generation will not complete.
# coverage # Name of output directory.
# )
#
# 4. Build a Debug build:
# cmake -DCMAKE_BUILD_TYPE=Debug ..
# make
# make my_coverage_target
#
#
# Check prereqs

.. _rfc-conformance:
***************
RFC Conformance
***************
JSON is specified in :rfc:`4627`, *"The application/json Media Type
for JavaScript Object Notation (JSON)"*.
Character Encoding
==================
Jansson only supports UTF-8 encoded JSON texts. It does not support or
auto-detect any of the other encodings mentioned in the RFC, namely
UTF-16LE, UTF-16BE, UTF-32LE or UTF-32BE. Pure ASCII is supported, as
it's a subset of UTF-8.
Strings
=======
JSON strings are mapped to C-style null-terminated character arrays,
and UTF-8 encoding is used internally.
All Unicode codepoints U+0000 through U+10FFFF are allowed in string
values. However, U+0000 is allowed in object keys only for length-aware functions.
Unicode normalization or any other transformation is never performed
on any strings (string values or object keys). When checking for
equivalence of strings or object keys, the comparison is performed
byte by byte between the original UTF-8 representations of the
strings.
Numbers
=======
.. _real-vs-integer:
Real vs. Integer
----------------
JSON makes no distinction between real and integer numbers; Jansson
does. Real numbers are mapped to the ``double`` type and integers to
the ``json_int_t`` type, which is a typedef of ``long long`` or
``long``, depending on whether ``long long`` is supported by your
compiler or not.
A JSON number is considered to be a real number if its lexical
representation includes one of ``e``, ``E``, or ``.``; regardless if
its actual numeric value is a true integer (e.g., all of ``1E6``,
``3.0``, ``400E-2``, and ``3.14E3`` are mathematical integers, but
will be treated as real values). With the ``JSON_DECODE_INT_AS_REAL``
decoder flag set all numbers are interpreted as real.
All other JSON numbers are considered integers.
When encoding to JSON, real values are always represented
with a fractional part; e.g., the ``double`` value 3.0 will be
represented in JSON as ``3.0``, not ``3``.
Overflow, Underflow & Precision
-------------------------------
Real numbers whose absolute values are too small to be represented in
a C ``double`` will be silently estimated with 0.0. Thus, depending on
platform, JSON numbers very close to zero such as 1E-999 may result in
0.0.
Real numbers whose absolute values are too large to be represented in
a C ``double`` will result in an overflow error (a JSON decoding
error). Thus, depending on platform, JSON numbers like 1E+999 or
-1E+999 may result in a parsing error.
Likewise, integer numbers whose absolute values are too large to be
represented in the ``json_int_t`` type (see above) will result in an
overflow error (a JSON decoding error). Thus, depending on platform,
JSON numbers like 1000000000000000 may result in parsing error.
Parsing JSON real numbers may result in a loss of precision. As long
as overflow does not occur (i.e. a total loss of precision), the
rounded approximate value is silently used. Thus the JSON number
1.000000000000000005 may, depending on platform, result in the
``double`` value 1.0.
Signed zeros
------------
JSON makes no statement about what a number means; however Javascript
(ECMAscript) does state that +0.0 and -0.0 must be treated as being
distinct values, i.e. -0.0 |not-equal| 0.0. Jansson relies on the
underlying floating point library in the C environment in which it is
compiled. Therefore it is platform-dependent whether 0.0 and -0.0 will
be distinct values. Most platforms that use the IEEE 754
floating-point standard will support signed zeros.
Note that this only applies to floating-point; neither JSON, C, or
IEEE support the concept of signed integer zeros.
.. |not-equal| unicode:: U+2260
Types
-----
No support is provided in Jansson for any C numeric types other than
``json_int_t`` and ``double``. This excludes things such as unsigned
types, ``long double``, etc. Obviously, shorter types like ``short``,
``int``, ``long`` (if ``json_int_t`` is ``long long``) and ``float``
are implicitly handled via the ordinary C type coercion rules (subject
to overflow semantics). Also, no support or hooks are provided for any
supplemental "bignum" type add-on packages.
Depth of nested values
======================
To avoid stack exhaustion, Jansson currently limits the nesting depth
for arrays and objects to a certain value (default: 2048), defined as
a macro ``JSON_PARSER_MAX_DEPTH`` within ``jansson_config.h``.
The limit is allowed to be set by the RFC; there is no recommended value
or required minimum depth to be supported.

refcounting
~~~~~~~~~~~
Reference count annotations for C API functions. Has the same
result as the sphinx.ext.refcounting extension but works for all
functions regardless of the signature, and the reference counting
information is written inline with the documentation instead of a

Adds a new directive "refcounting". The directive has no content
and one required positional parameter:: "new" or "borrow".
Example:

Compiling and Installing Jansson
================================
The Jansson source is available at
http://www.digip.org/jansson/releases/.
Unix-like systems (including MinGW)
-----------------------------------
Unpack the source tarball and change to the source directory:
.. parsed-literal::
bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
cd jansson-|release|
The source uses GNU Autotools (autoconf_, automake_, libtool_), so
compiling and installing is extremely simple::
./configure
make
make check
make install
To change the destination directory (``/usr/local`` by default), use
the ``--prefix=DIR`` argument to ``./configure``. See ``./configure
--help`` for the list of all possible configuration options.
The command ``make check`` runs the test suite distributed with
Jansson. This step is not strictly necessary, but it may find possible
problems that Jansson has on your platform. If any problems are found,
please report them.
If you obtained the source from a Git repository (or any other source
control system), there's no ``./configure`` script as it's not kept in
version control. To create the script, the build system needs to be
bootstrapped. There are many ways to do this, but the easiest one is
to use ``autoreconf``::
autoreconf -fi
This command creates the ``./configure`` script, which can then be
used as described above.
.. _autoconf: http://www.gnu.org/software/autoconf/
.. _automake: http://www.gnu.org/software/automake/
.. _libtool: http://www.gnu.org/software/libtool/
.. _build-cmake:
CMake (various platforms, including Windows)
--------------------------------------------
Jansson can be built using CMake_. Create a build directory for an
out-of-tree build, change to that directory, and run ``cmake`` (or ``ccmake``,
``cmake-gui``, or similar) to configure the project.
See the examples below for more detailed information.
.. note:: In the below examples ``..`` is used as an argument for ``cmake``.
This is simply the path to the jansson project root directory.
In the example it is assumed you've created a sub-directory ``build``
and are using that. You could use any path you want.
.. _build-cmake-unix:
Unix (Make files)
^^^^^^^^^^^^^^^^^
Generating make files on unix:
.. parsed-literal::
bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
cd jansson-|release|
mkdir build
cd build
cmake .. # or ccmake .. for a GUI.
.. note::
If you don't want to build docs or ``Sphinx`` is not installed, you should add ``"-DJANSSON_BUILD_DOCS=OFF"`` in the ``cmake`` command.
Then to build::
make
make check
make install
Windows (Visual Studio)
^^^^^^^^^^^^^^^^^^^^^^^
Creating Visual Studio project files from the command line:
.. parsed-literal::
<unpack>
cd jansson-|release|
md build
cd build
cmake -G "Visual Studio 15 2017" ..
.. note::
You should replace the name of the generator (``-G`` flag) matching
the Visual Studio version installed on your system. Currently, the
following versions are supported:
- ``Visual Studio 9 2008``
- ``Visual Studio 10 2010``
- ``Visual Studio 11 2012``
- ``Visual Studio 12 2013``
- ``Visual Studio 14 2015``
- ``Visual Studio 15 2017``
- ``Visual Studio 16 2019``
Any later version should also work.
You will now have a *Visual Studio Solution* in your build directory.
To run the unit tests build the ``RUN_TESTS`` project.
If you prefer a GUI the ``cmake`` line in the above example can
be replaced with::
cmake-gui ..
For command line help (including a list of available generators)
for CMake_ simply run::
cmake
To list available CMake_ settings (and what they are currently set to)
for the project, run::
cmake -LH ..
Windows (MinGW)
^^^^^^^^^^^^^^^
If you prefer using MinGW on Windows, make sure MinGW installed and ``{MinGW}/bin`` has been added to ``PATH``, then do the following commands:
.. parsed-literal::
<unpack>
cd jansson-|release|
md build
cd build
cmake -G "MinGW Makefiles" ..
mingw32-make
Mac OSX (Xcode)
^^^^^^^^^^^^^^^
If you prefer using Xcode instead of make files on OSX,
do the following. (Use the same steps as
for :ref:`Unix <build-cmake-unix>`)::
...
cmake -G "Xcode" ..
Additional CMake settings
^^^^^^^^^^^^^^^^^^^^^^^^^
Shared library
""""""""""""""
By default the CMake_ project will generate build files for building the
static library. To build the shared version use::
...
cmake -DJANSSON_BUILD_SHARED_LIBS=1 ..
Changing install directory (same as autoconf --prefix)
""""""""""""""""""""""""""""""""""""""""""""""""""""""
Just as with the autoconf_ project you can change the destination directory
for ``make install``. The equivalent for autoconfs ``./configure --prefix``
in CMake_ is::
...
cmake -DCMAKE_INSTALL_PREFIX:PATH=/some/other/path ..
make install
.. _CMake: http://www.cmake.org
Android
-------
Jansson can be built for Android platforms. Android.mk is in the
source root directory. The configuration header file is located in the
``android`` directory in the source distribution.
Other Systems
-------------
On non Unix-like systems, you may be unable to run the ``./configure``
script. In this case, follow these steps. All the files mentioned can
be found in the ``src/`` directory.
1. Create ``jansson_config.h`` (which has some platform-specific
parameters that are normally filled in by the ``./configure``
script). Edit ``jansson_config.h.in``, replacing all ``@variable@``
placeholders, and rename the file to ``jansson_config.h``.
2. Make ``jansson.h`` and ``jansson_config.h`` available to the
compiler, so that they can be found when compiling programs that
use Jansson.
3. Compile all the ``.c`` files (in the ``src/`` directory) into a
library file. Make the library available to the compiler, as in
step 2.
Building the Documentation
--------------------------
(This subsection describes how to build the HTML documentation you are
currently reading, so it can be safely skipped.)
Documentation is in the ``doc/`` subdirectory. It's written in
reStructuredText_ with Sphinx_ annotations. To generate the HTML
documentation, invoke::
make html
and point your browser to ``doc/_build/html/index.html``. Sphinx_ 1.0
or newer is required to generate the documentation.
.. _reStructuredText: http://docutils.sourceforge.net/rst.html
.. _Sphinx: http://sphinx.pocoo.org/
Compiling Programs that Use Jansson
===================================
Jansson involves one C header file, :file:`jansson.h`, so it's enough
to put the line
::
#include <jansson.h>
in the beginning of every source file that uses Jansson.
There's also just one library to link with, ``libjansson``. Compile and
link the program as follows::
cc -o prog prog.c -ljansson
Starting from version 1.2, there's also support for pkg-config_:
.. code-block:: shell
cc -o prog prog.c `pkg-config --cflags --libs jansson`
.. _pkg-config: http://pkg-config.freedesktop.org/

Jansson Documentation
=====================
This is the documentation for Jansson_ |release|, last updated |today|.
Introduction
------------
Jansson_ is a C library for encoding, decoding and manipulating JSON
data. Its main features and design principles are:
- Simple and intuitive API and data model
- Comprehensive documentation
- No dependencies on other libraries
- Full Unicode support (UTF-8)
- Extensive test suite
Jansson is licensed under the `MIT license`_; see LICENSE in the
source distribution for details.
Jansson is used in production and its API is stable. It works on
numerous platforms, including numerous Unix like systems and Windows.
It's suitable for use on any system, including desktop, server, and
small embedded systems.

*************
Thread safety
*************
.. _thread-safety:
Jansson as a library is thread safe and has no mutable global state.
The only exceptions are the hash function seed and memory allocation
functions, see below.
There's no locking performed inside Jansson's code. **Read-only**
access to JSON values shared by multiple threads is safe, but
**mutating** a JSON value that's shared by multiple threads is not. A
multithreaded program must perform its own locking if JSON values
shared by multiple threads are mutated.
However, **reference count manipulation** (:func:`json_incref()`,
:func:`json_decref()`) is usually thread-safe, and can be performed on
JSON values that are shared among threads. The thread-safety of
reference counting can be checked with the
``JANSSON_THREAD_SAFE_REFCOUNT`` preprocessor constant. Thread-safe
reference count manipulation is achieved using compiler built-in
atomic functions, which are available in most modern compilers.
If compiler support is not available (``JANSSON_THREAD_SAFE_REFCOUNT``
is not defined), it may be very difficult to ensure thread safety of
reference counting. It's possible to have a reference to a value
that's also stored inside an array or object in another thread.
Modifying the container (adding or removing values) may trigger
concurrent access to such values, as containers manage the reference
count of their contained values.
Hash function seed
==================
To prevent an attacker from intentionally causing large JSON objects
with specially crafted keys to perform very slow, the hash function
used by Jansson is randomized using a seed value. The seed is
automatically generated on the first explicit or implicit call to
:func:`json_object()`, if :func:`json_object_seed()` has not been
called beforehand.
The seed is generated by using operating system's entropy sources if
they are available (``/dev/urandom``, ``CryptGenRandom()``). The
initialization is done in as thread safe manner as possible, by using
architecture specific lockless operations if provided by the platform
or the compiler.
If you're using threads, it's recommended to autoseed the hashtable
explicitly before spawning any threads by calling
``json_object_seed(0)`` , especially if you're unsure whether the
initialization is thread safe on your platform.
Memory allocation functions
===========================
Memory allocation functions should be set at most once, and only on
program startup. See :ref:`apiref-custom-memory-allocation`.
Locale
======
Jansson works fine under any locale.
However, if the host program is multithreaded and uses ``setlocale()``
to switch the locale in one thread while Jansson is currently encoding
or decoding JSON data in another thread, the result may be wrong or
the program may even crash.
Jansson uses locale specific functions for certain string conversions
in the encoder and decoder, and then converts the locale specific
values to/from the JSON representation. This fails if the locale
changes between the string conversion and the locale-to-JSON
conversion. This can only happen in multithreaded programs that use
``setlocale()``, because ``setlocale()`` switches the locale for all
running threads, not only the thread that calls ``setlocale()``.
If your program uses ``setlocale()`` as described above, consider
using the thread-safe ``uselocale()`` instead.

Tutorial
********
.. highlight:: c
In this tutorial, we create a program that fetches the latest commits
of a repository in GitHub_ over the web. `GitHub API`_ uses JSON, so
the result can be parsed using Jansson.
To stick to the scope of this tutorial, we will only cover the
parts of the program related to handling JSON data. For the best user
experience, the full source code is available:
:download:`github_commits.c`. To compile it (on Unix-like systems with
gcc), use the following command::
gcc -o github_commits github_commits.c -ljansson -lcurl
libcurl_ is used to communicate over the web, so it is required to
compile the program.
The command line syntax is::
github_commits USER REPOSITORY
``USER`` is a GitHub user ID and ``REPOSITORY`` is the repository
name. Please note that the GitHub API is rate limited, so if you run
the program too many times within a short period of time, the sever
starts to respond with an error.
.. _GitHub: https://github.com/
.. _GitHub API: http://developer.github.com/
.. _libcurl: http://curl.haxx.se/
.. _tutorial-github-commits-api:
The GitHub Repo Commits API
===========================
The `GitHub Repo Commits API`_ is used by sending HTTP requests to
URLs like ``https://api.github.com/repos/USER/REPOSITORY/commits``,
where ``USER`` and ``REPOSITORY`` are the GitHub user ID and the name
of the repository whose commits are to be listed, respectively.
GitHub responds with a JSON array of the following form:
.. code-block:: none
[
{
"sha": "<the commit ID>",
"commit": {
"message": "<the commit message>",
<more fields, not important to this tutorial...>
},
<more fields...>
},
{
"sha": "<the commit ID>",
"commit": {
"message": "<the commit message>",
<more fields...>
},
<more fields...>
},
<more commits...>
]
In our program, the HTTP request is sent using the following
function::
static char *request(const char *url);
It takes the URL as a parameter, performs a HTTP GET request, and
returns a newly allocated string that contains the response body. If
the request fails, an error message is printed to stderr and the
return value is *NULL*. For full details, refer to :download:`the code
<github_commits.c>`, as the actual implementation is not important
here.
.. _GitHub Repo Commits API: http://developer.github.com/v3/repos/commits/
.. _tutorial-the-program:
The Program
===========
First the includes::
#include <string.h>
#include <jansson.h>
Like all the programs using Jansson, we need to include
:file:`jansson.h`.
The following definitions are used to build the GitHub API request
URL::
#define URL_FORMAT "https://api.github.com/repos/%s/%s/commits"
#define URL_SIZE 256
The following function is used when formatting the result to find the
first newline in the commit message::
/* Return the offset of the first newline in text or the length of
text if there's no newline */
static int newline_offset(const char *text)
{
const char *newline = strchr(text, '\n');
if(!newline)
return strlen(text);
else
return (int)(newline - text);
}
The main function follows. In the beginning, we first declare a bunch
of variables and check the command line parameters::
int main(int argc, char *argv[])
{
size_t i;
char *text;
char url[URL_SIZE];
json_t *root;
json_error_t error;
if(argc != 3)
{
fprintf(stderr, "usage: %s USER REPOSITORY\n\n", argv[0]);
fprintf(stderr, "List commits at USER's REPOSITORY.\n\n");
return 2;
}
Then we build the request URL using the user and repository names
given as command line parameters::
snprintf(url, URL_SIZE, URL_FORMAT, argv[1], argv[2]);
This uses the ``URL_SIZE`` and ``URL_FORMAT`` constants defined above.
Now we're ready to actually request the JSON data over the web::
text = request(url);
if(!text)
return 1;
If an error occurs, our function ``request`` prints the error and
returns *NULL*, so it's enough to just return 1 from the main
function.
Next we'll call :func:`json_loads()` to decode the JSON text we got
as a response::
root = json_loads(text, 0, &error);
free(text);
if(!root)
{
fprintf(stderr, "error: on line %d: %s\n", error.line, error.text);
return 1;
}
We don't need the JSON text anymore, so we can free the ``text``
variable right after decoding it. If :func:`json_loads()` fails, it
returns *NULL* and sets error information to the :type:`json_error_t`
structure given as the second parameter. In this case, our program
prints the error information out and returns 1 from the main function.
Now we're ready to extract the data out of the decoded JSON response.
The structure of the response JSON was explained in section
:ref:`tutorial-github-commits-api`.
We check that the returned value really is an array::
if(!json_is_array(root))
{
fprintf(stderr, "error: root is not an array\n");
json_decref(root);
return 1;
}
Then we proceed to loop over all the commits in the array::
for(i = 0; i < json_array_size(root); i++)
{
json_t *data, *sha, *commit, *message;
const char *message_text;
data = json_array_get(root, i);
if(!json_is_object(data))
{
fprintf(stderr, "error: commit data %d is not an object\n", i + 1);
json_decref(root);
return 1;
}
...
The function :func:`json_array_size()` returns the size of a JSON
array. First, we again declare some variables and then extract the
i'th element of the ``root`` array using :func:`json_array_get()`.
We also check that the resulting value is a JSON object.
Next we'll extract the commit ID (a hexadecimal SHA-1 sum),
intermediate commit info object, and the commit message from that
object. We also do proper type checks::
sha = json_object_get(data, "sha");
if(!json_is_string(sha))
{
fprintf(stderr, "error: commit %d: sha is not a string\n", i + 1);
json_decref(root);
return 1;
}
commit = json_object_get(data, "commit");
if(!json_is_object(commit))
{
fprintf(stderr, "error: commit %d: commit is not an object\n", i + 1);
json_decref(root);
return 1;
}
message = json_object_get(commit, "message");
if(!json_is_string(message))
{
fprintf(stderr, "error: commit %d: message is not a string\n", i + 1);
json_decref(root);
return 1;
}
...
And finally, we'll print the first 8 characters of the commit ID and
the first line of the commit message. A C-style string is extracted
from a JSON string using :func:`json_string_value()`::
message_text = json_string_value(message);
printf("%.8s %.*s\n",
json_string_value(sha),
newline_offset(message_text),
message_text);
}
After sending the HTTP request, we decoded the JSON text using
:func:`json_loads()`, remember? It returns a *new reference* to the
JSON value it decodes. When we're finished with the value, we'll need
to decrease the reference count using :func:`json_decref()`. This way
Jansson can release the resources::
json_decref(root);
return 0;
For a detailed explanation of reference counting in Jansson, see
:ref:`apiref-reference-count` in :ref:`apiref`.
The program's ready, let's test it and view the latest commits in
Jansson's repository:

Conclusion
==========
In this tutorial, we implemented a program that fetches the latest
commits of a GitHub repository using the GitHub Repo Commits API.
Jansson was used to decode the JSON response and to extract the commit
data.
This tutorial only covered a small part of Jansson. For example, we
did not create or manipulate JSON values at all. Proceed to
:ref:`apiref` to explore all features of Jansson.

******************
Upgrading from 1.x
******************
This chapter lists the backwards incompatible changes introduced in
Jansson 2.0, and the steps that are needed for upgrading your code.
**The incompatibilities are not dramatic.** The biggest change is that
all decoding functions now require and extra parameter. Most programs
can be modified to work with 2.0 by adding a ``0`` as the second
parameter to all calls of :func:`json_loads()`, :func:`json_loadf()`
and :func:`json_load_file()`.
Compatibility
=============
Jansson 2.0 is backwards incompatible with the Jansson 1.x releases.
It is ABI incompatible, i.e. all programs dynamically linking to the
Jansson library need to be recompiled. It's also API incompatible,
i.e. the source code of programs using Jansson 1.x may need
modifications to make them compile against Jansson 2.0.
All the 2.x releases are guaranteed to be backwards compatible for
both ABI and API, so no recompilation or source changes are needed
when upgrading from 2.x to 2.y.
List of Incompatible Changes
============================
**Decoding flags**
For future needs, a ``flags`` parameter was added as the second
parameter to all decoding functions, i.e. :func:`json_loads()`,
:func:`json_loadf()` and :func:`json_load_file()`. All calls to
these functions need to be changed by adding a ``0`` as the second
argument. For example::
/* old code */
json_loads(input, &error);
/* new code */
json_loads(input, 0, &error);
**Underlying type of JSON integers**
The underlying C type of JSON integers has been changed from
``int`` to the widest available signed integer type, i.e.
``long long`` or ``long``, depending on whether
``long long`` is supported on your system or not. This makes
the whole 64-bit integer range available on most modern systems.
``jansson.h`` has a typedef :type:`json_int_t` to the underlying
integer type. ``int`` should still be used in most cases when
dealing with smallish JSON integers, as the compiler handles
implicit type coercion. Only when the full 64-bit range is needed,
:type:`json_int_t` should be explicitly used.
**Maximum encoder indentation depth**
The maximum argument of the ``JSON_INDENT()`` macro has been
changed from 255 to 31, to free up bits from the ``flags``
parameter of :func:`json_dumps()`, :func:`json_dumpf()` and
:func:`json_dump_file()`. If your code uses a bigger indentation
than 31, it needs to be changed.
**Unsigned integers in API functions**
Version 2.0 unifies unsigned integer usage in the API. All uses of
``unsigned int`` and ``unsigned long`` have been replaced
with ``size_t``. This includes flags, container sizes, etc.
This should not require source code changes, as both
``unsigned int`` and ``unsigned long`` are usually
compatible with ``size_t``.

-------------------------------------------------------------------------------
lookup3.c, by Bob Jenkins, May 2006, Public Domain.
These are functions for producing 32-bit hashes for hash table lookup.
hashword(), hashlittle(), hashlittle2(), hashbig(), mix(), and final()
are externally useful functions. Routines to test the hash are included
if SELF_TEST is defined. You can use this free for any purpose. It's in
the public domain. It has no warranty.
You probably want to use hashlittle(). hashlittle() and hashbig()
hash byte arrays. hashlittle() is is faster than hashbig() on
little-endian machines. Intel and AMD are little-endian machines.
On second thought, you probably want hashlittle2(), which is identical to
hashlittle() except it returns two 32-bit hashes for the price of one.
You could implement hashbig2() if you wanted but I haven't bothered here.
If you want to find a hash of, say, exactly 7 integers, do
a = i1; b = i2; c = i3;
mix(a,b,c);
a += i4; b += i5; c += i6;
mix(a,b,c);
a += i7;
final(a,b,c);
then use c as the hash value. If you have a variable length array of
4-byte integers to hash, use hashword(). If you have a byte array (like
a character string), use hashlittle(). If you have several byte arrays, or
a mix of things, see the comments above hashlittle().
Why is this so big? I read 12 bytes at a time into 3 4-byte integers,
then mix those integers. This is fast (you can do a lot more thorough
mixing with 12*3 instructions on 3 integers than you can with 3 instructions
on 1 byte), but shoehorning those bytes into integers efficiently is messy.

This is reversible, so any information in (a,b,c) before mix() is
still in (a,b,c) after mix().
If four pairs of (a,b,c) inputs are run through mix(), or through
mix() in reverse, there are at least 32 bits of the output that
are sometimes the same for one pair and different for another pair.
This was tested for:
* pairs that differed by one bit, by two bits, in any combination
of top bits of (a,b,c), or in any combination of bottom bits of
(a,b,c).
* "differ" is defined as +, -, ^, or ~^. For + and -, I transformed
the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
is commonly produced by subtraction) look like a single 1-bit
difference.
* the base values were pseudorandom, all zero but one bit set, or
all zero plus a counter that starts at zero.
Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
satisfy this are
4 6 8 16 19 4
9 15 3 18 27 15
14 9 3 7 17 3
Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing
for "differ" defined as + with a one-bit base and a two-bit delta. I
used http://burtleburtle.net/bob/hash/avalanche.html to choose
the operations, constants, and arrangements of the variables.
This does not achieve avalanche. There are input bits of (a,b,c)
that fail to affect some output bits of (a,b,c), especially of a. The
most thoroughly mixed value is c, but it doesn't really even achieve
avalanche in c.
This allows some parallelism. Read-after-writes are good at doubling
the number of bits affected, so the goal of mixing pulls in the opposite
direction as the goal of parallelism. I did what I could. Rotates
seem to cost as much as shifts on every machine I could lay my hands
on, and rotates are much kinder to the top and bottom bits, so I used
rotates.

final -- final mixing of 3 32-bit values (a,b,c) into c
Pairs of (a,b,c) values differing in only a few bits will usually
produce values of c that look totally different. This was tested for
* pairs that differed by one bit, by two bits, in any combination
of top bits of (a,b,c), or in any combination of bottom bits of
(a,b,c).
* "differ" is defined as +, -, ^, or ~^. For + and -, I transformed
the output delta to a Gray code (a^(a>>1)) so a string of 1's (as
is commonly produced by subtraction) look like a single 1-bit
difference.
* the base values were pseudorandom, all zero but one bit set, or
all zero plus a counter that starts at zero.
These constants passed:
14 11 25 16 4 14 24
12 14 25 16 4 14 24
and these came close:
4 8 15 26 3 22 24

hashlittle() -- hash a variable-length key into a 32-bit value
k : the key (the unaligned variable-length array of bytes)
length : the length of the key, counting by bytes
initval : can be any 4-byte value
Returns a 32-bit value. Every bit of the key affects every bit of
the return value. Two keys differing by one or two bits will have
totally different hash values.
The best hash table sizes are powers of 2. There is no need to do
mod a prime (mod is sooo slow!). If you need less than 32 bits,
use a bitmask. For example, if you need only 10 bits, do
h = (h & hashmask(10));
In which case, the hash table should have hashsize(10) elements.
If you are hashing n strings (uint8_t **)k, do it like this:
for (i=0, h=0; i<n; ++i) h = hashlittle( k[i], len[i], h);
By Bob Jenkins, 2006. bob_jenkins@burtleburtle.net. You may use this
code any way you wish, private, educational, or commercial. It's free.
Use for hash table lookup, or anything where one collision in 2^^32 is
acceptable. Do NOT use for cryptographic purposes.
