    JsonCpp

    JsonCpp

    A C++ library for interacting with JSON

    JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs. JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files. The branch 00.11.zis a new branch, its major version number 00 is to show that it is different from 0.y.z and 1.y.z, the main purpose of this branch is to make a balance between the other two branches. Thus, users can use some new features in this new branch that introduced in 1.y.z, but can hardly applied into 0.y.z. You can download and install JsonCpp using the vcpkg dependency manager. The JsonCpp port in vcpkg is kept up to date by Microsoft team members and community contributors.

    JSON for Modern C++

    JSON that's part of C++

    This is JSON for C++, a JSON library unlike any other that's packed with plenty of great features. While there may be dozens of JSON libraries out there, JSON for C++ stands out with a focus on three things: an intuitive syntax, trivial integration and serious testing. Using the operator magic of modern C++, this library makes JSON feel like a first class data type. With trivial integration, the entire code is made up of a single header file json.hpp, no dependencies, no complex build system required. It's been heavily unit-tested covering 100% of the code, and follows the Core Infrastructure Initiative (CII) best practices to ensure the highest quality at all times. Among its many features are JSON pointers, JSON patches, Iterators, SAX parsing and various container operations.

    ArduinoJson

    ArduinoJson

    JSON library for Arduino and embedded C++. Simple and efficient

    ArduinoJson is a C++ JSON library for Arduino and IoT (Internet Of Things). ArduinoJson has a simple and intuitive syntax to handle objects and arrays. ArduinoJson supports both JSON serialization and deserialization. ArduinoJson uses a fixed memory allocation, allowing to work on devices with very little RAM. ArduinoJson can filter large inputs to keep only fields that are relevant to your application, thereby saving a lot of memory. ArduinoJson can parse directly from an input Stream or std::istream. ArduinoJson can produce compact or prettified documents. ArduinoJson works directly with strings stored in program memory. ArduinoJson supports two coding styles, with implicit or explicit casts. ArduinoJson deduplicates strings in the JSON document. When you have several identical keys or values, the JsonDocument only stores one of each. In practice, this feature reduces memory consumption by 20-30%.

    Cutelyst

    Cutelyst

    Web Framework built on top of Qt, using the approach of Catalyst

    Create fast and modern web applications that share the same code as your desktop or mobile apps. Why have two or more development teams focused on a specific platform when you can have a single team coding the same code, sharing skills and lines of code. With Qt, you already can write applications for Windows, Linux, Android, MacOS, and iOS using the same source code, Cutelyst allows you to share your C++ code with your web application. Cutelyst has a WSGI server that supports HTTP/1.1, HTTP/2, FastCGI, and WebSockets, it can even be embedded in your application if you like. It also features a plugin for uWSGI which gives us support for HTTP/1.0, FastCGI, and uWSGI protocols but is slower and doesn't support WebSockets. Running standalone or behind a web server is really easy. With your application logic written in C++ your application get's really small, a full CMS (like this one) uses around 5MB of RAM which can be shared with other instances of the same application.

    Vince's CSV Parser

    Vince's CSV Parser

    A modern C++ library for reading, writing, and analyzing CSV

    There's plenty of other CSV parsers in the wild, but I had a hard time finding what I wanted. Inspired by Python's csv module, I wanted a library with simple, intuitive syntax. Furthermore, I wanted support for special use cases such as calculating statistics on very large files. With the deluge of large datasets available, a performant CSV parser is a necessity. By using overlapped threads, memory-mapped IO, and efficient data structures, this parser can quickly tackle large CSV files. Furthermore, this parser has a minimal memory footprint and can handle larger-than-RAM files.

    TreeFrog Framework, High-speed C++ MVC Framework for Web Applications

    TreeFrog Framework is a high-speed and full-stack C++ framework for developing Web applications, which supports HTTP and WebSocket protocol. Web applications can run faster than that of scripting language because the server-side framework was written in C++/Qt. In application development, it provides an O/R mapping system and template systems on an MVC architecture, aims to achieve high productivity through the policy of convention over configuration. TreeFrog Framework is cross-platform. It runs on Windows, of course, but also on UNIX-like Operating Systems, macOS, and Linux. Using Windows open-source coding, it is possible to support Linux. Web applications that run on multiple platforms are also possible, simply by recompiling the source code. TreeFrog Framework is open-source software, under the new BSD license (3-clause BSD License).

    JSON Parser

    JSON Parser

    JSON Parser written in C that outputs JSON into D-List list objects

    JSON parser is a highly efficient JSON data decoder written in C, that parses JSON data into a form that is very easy to use from within C code. You only need to include the json-parser.h file in your source code. If your project does not already incorporate D-List, you will also need to include dlist.h The JSON parser package also includes a JSON validator that does not parse or create resources, but allows the caller to validate JSON data from unknown sources, prior to any parsing attempts. The JSON data is returned to the caller as a set of hierarchical D-List list objects, that make the data very easy to manage, sort, search or use, and easy to remove when done. Package includes a JSON textural generator which will create JSON grammar data blocks from hierarchical D-List representations of JSON data. The package also includes a variety of support functions to allow C code to easily find, add, and modify JSON values and members in D-List hierarchical structures.

    QBooru is a lightweight Windows and Linux client that allows users to see pictures from most booru sites, and download them, for example : - Gelbooru - Danbooru - Konachan - Yandere - Safebooru - Rule34 At the moment, it supports 4 APIs : - Gelbooru - Danbooru 2 - Moebooru - Derpibooru Searchs are done by the JSON APIs. Thumbnails are cached locally, and are re-used by the program if needed. Interface The current interface allows users to chose how many pictures they want, within 3-5 rows and 5-8 columns. The recommended size is 3*5, as it fits perfectly the smallest window size. Search tab example : http://puu.sh/cK0pj.jpg Users can change nearly all the parameters through the Option tab, or by editing the configuration.json file. Boorus can be added, edited, and deleted through the Booru tab in the software, but they can also be edited manually in the configuration file.

    Occursions

    Fast customizable time series web database for big data like log files

    Our goal is to create the world's fastest extendable, non-transactional time series database for big data (you know, for kids)! Log file indexing is our initial focus. For example append only ASCII files produced by libraries like Log4J, or containing FIX messages or JSON objects. Occursions was built by a small team sick of creating hacks to remotely copy and/or grep through tons of large log files. We use it to index around a terabyte of new log data per day. You can use it too. Who doesn't have `just too many' log files? Occursions asynchronously tails log files and indexes the individual lines in each log file as each line is written to disk so you don't even have to wait for a second after an event happens to search for it. Occursions uses custom disk backed data structures to create and search its indexes so it is very efficient at using CPU, memory and disk. You can extend Occursions with shared libraries to support your own file formats, even binary file formats!
