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.

If you obtained a jansson-X.Y.tar.* tarball from GitHub Releases, 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 is available at https://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.
