# sjson-cpp

`sjson-cpp` is a C++ library to read and write [Simplified JSON](http://help.autodesk.com/view/Stingray/ENU/?guid=__stingray_help_managing_content_sjson_html) files.
It aims to be minimal, fast, and get out of the way of the programmer.

By design, the library does no memory allocations. This is in contrast to the [nflibs C parser](https://github.com/niklasfrykholm/nflibs).

Everything is **100% C++11** header based for easy and trivial integration.

This parser is intended to accept only pure SJSON, and it will fail if given a JSON file, unlike the [Autodesk JS Stingray parser](https://github.com/Autodesk/sjson).

## The SJSON format

The data format is described [here](http://help.autodesk.com/view/Stingray/ENU/?guid=__stingray_help_managing_content_sjson_html) in the Stingray documentation.

TODO: Add a reference sjson file showing the format as a form of loose specification

## Unicode support

UTF-8 support is as follow:

* String values return a raw `StringView` into the SJSON buffer. It is the responsability of the caller to interpret it as ANSI or UTF-8.
* String values properly support escaped unicode sequences in that they are returned raw in the `StringView`.
* Keys do not support UTF-8, they must be ANSI.
* The BOM is properly skipped if present

Unicode formats other than UTF-8 aren't supported.

## Supported platforms

* Windows VS2015 x86 and x64
* Windows (VS2017 to VS2022) x86, x64, and ARM64
* Windows (VS2017 to VS2022) with clang x86 and x64
* Linux (gcc 5 to 13) x86 and x64
* Linux (clang 4 to 15) x86 and x64
* OS X (XCode 12.5, 13.2, 14.2) x64 and ARM64
* Android (NDK 21) ARMv7-A and ARM64
* iOS (Xcode 10.3, 11.7, 12.5, 13.2, 14.2) ARM64
* Emscripten (1.39.11) WASM
* MSYS2 x64

The above supported platform list is only what is tested every release but if it compiles, it should run just fine.

## External dependencies

There are none! You don't need anything else to get started: everything is self contained.
See [here](./external) for details.

## Getting up and running

This library is **100%** headers as such you just need to include them in your own project to start using it. However, if you wish to run the unit tests you will need a few things, see below.

### Windows, Linux, and OS X for x86 and x64

1. Install *CMake 3.2* or higher (*3.14* for Visual Studio 2019, or *3.10* on OS X with *Xcode 10*), *Python 2.7 or 3*, and the proper compiler for your platform.
2. Execute `git submodule update --init` to get the files of external submodules (e.g. Catch2).
3. Generate the IDE solution with: `python make.py`
The solution is generated under `./build`
4. Build the IDE solution with: `python make.py -build`
5. Run the unit tests with: `python make.py -unit_test`

### Windows ARM64

For *Windows on ARM64*, the steps are identical to *x86 and x64* but you will need *CMake 3.13 or higher* and you must provide the architecture on the command line: `python make.py -compiler vs2017 -cpu arm64`

### Android

For *Android*, the steps are identical to *Windows, Linux, and OS X* but you also need to install *Android NDK 21* (or higher). The build uses `gradle` and `-unit_test` will deploy and run on the device when executed (make sure that the `adb` executable is in your `PATH` for this to work).

*Android Studio v3.5* can be used to launch and debug. After running *CMake* to build and generate everything, the *Android Studio* projects can be found under the `./build` directory.

### iOS

For *iOS*, the steps are identical to the other platforms but due to code signing, you will need to perform the builds from *Xcode* manually. Note that this is only an issue if you attempt to use the tools or run the unit tests locally.

### Emscripten

Emscripten support currently only has been tested on OS X and Linux. To use it, make sure to install a recent version of Emscripten SDK 1.39.11+.

## Commit message format

This library uses the [angular.js message format](https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#commits) and it is enforced with commit linting through every pull request.
