JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

The wxJSON library is a complete implementation of the JSON data-interchange format. All JSON specifications are implemented in this library plus some extensions in the writer and in the parser class.

Today wxJSON 1.1.0 was announced. This release is compatible with both wxWidgets 2.8 and 2.9. It is also compatible with wxWidgets SVN HEAD. Now JSON reader and writer only process UTF-8 encoded text as a stream.
Also added a new wxJSONValue’s member function to get values and fixed the bugs in wxJSONValue::IsSameAs()

This is the first stable release of the wxJSON library. The major version had changed because I introduced some compatibility breaks with the old 0.x versions as well as some new features.

This wxJSON release adds support for 64-bits integers on those platforms that have native support for it such as, for example, Windows and GNU/Linux.

You can disable 64-bits integer support if you do not need (or do not want) it. The new version is compatible wih the past: if you do not need 64-bits integers you can still use this new version of the library without the need to rewrite your application.

This release adds the ‘copy-on-write’ feature to the copy ctor and assignment operator of JSON value class.
Note that this new feature only affects the internal representation of JSON values and does not add new features in the class’s interface.
Also note that for JSON value objects, COW is not as efficient as expected.

The wxJSON library is now complete and this release should be considered a final beta release.
JSON data format is very stable. It is accredited to be stable forever or, at least, until programming language’s variables are based on numbers, strings, booleans, structures and arrays.

No other feature should have to be added to the library and I think that, after a few months used for discovering and fixing bugs, I will release the stable version 1.0

This will be the good occasion to, eventually, break the compatibility with the old versions 0.x by changing memberfunction’s names and/or parameters.
If you have any comment, suggestion or hint, feel free to write to me or post an answer to this topic.

Using Comment Lines in wxJSON

Comments are not supported by the JSON syntax specifications but many JSON implementations do recognize and store comment lines in the JSON value objects. Starting by version 0.2, the wxJSON library do recognize and store C/C++ comment lines in the JSON input text and can also write comments to the JSON output text.

Describing a Table with wxJSON

How many times did you use a table in your application? I know the answer: many times. So the best thing would be to write a general-purpose panel window that is capable to show every possible table and table’s format.

Creating a Configuration File with wxJSON

We start by using JSON for an application’s configuration file. There are many formats for storing application’s configuration data. I remember when there was MS-DOS: each application used its own, unreadable and proprietary format (it was a nightmare). Next came Windows 3: it had a better way for storing application’s configuration data; they were kept in an .INI file which contains simple ASCII text. This was a good thing because it was easier for humans to fine-tuning application’s behaviour.

In this example we use JSON to store the configuration data of a simple web server application. If you take a look at the Apache config file you will notice that our example looks very similar (but much more human readable).
