NOTE: Current source code as well as bugs/patches are on GitHub: https://github.com/pocoproject/poco/ C++ class libraries for network-centric, portable applications, integrated perfectly with the C++ Standard Library. Includes network protocols (Sockets, HTTP, FTP, SMTP, POP3, etc.), SQL database access and XML parsing. Licensed under Boost license.

NOTE: the code for this project has migrated to GitHub at https://github.com/axiomatic-systems/Bento4 It is still available through SourceForge for a short time, but please update your links. Bento4 is a Portable C++ Class Library and tools for parsing and creating ISO MP4 (ISO 14496-12, 14496-14 and 14496-15), iTunes, Quicktime, OMA DCF/PDCF, PIFF, DECE, and MPEG-DASH or Smooth Streaming files containing MPEG-4 or other types of media streams.

Fast, convenient JSON serialization and parsing in C++. The DAW JSON Link library is a high-performance, no allocation, C++ JSON Library. Direct parsing of JSON to your own data structures via simple declarative mappings. Earlier error reporting of unexpected data and errors. Low memory requirement, parser requires a small amount of stack but does not allocate itself. Optimizations based on data types. Does not require owning the mapped types and is not intrusive.

Infer is a static analysis tool - if you give Infer some Java or C/C++/Objective-C code it produces a list of potential bugs. Anyone can use Infer to intercept critical bugs before they have shipped to users, and help prevent crashes or poor performance. Infer checks for null pointer exceptions, resource leaks, annotation reachability, missing lock guards, and concurrency race conditions in Android and Java code. Infer checks for null pointer dereferences, memory leaks, coding conventions and unavailable API’s. Start with the Getting Started guide and our other docs to download and try Infer yourself. Infer is still evolving, and we want to continue to develop it in the open. We hope it will be useful for other projects, so please try it out or contribute to it, join the community and give us feedback!

PJON® (Padded Jittering Operative Network) is an experimental, Arduino-compatible, multi-master, multi-media, software-defined network protocol that can be easily cross-compiled on many microcontrollers and real-time operative systems like ATtiny, ATmega, SAMD, ESP8266, ESP32, STM32, Teensy, Raspberry Pi, Zephyr, Linux, Windows x86, Apple and Android. PJON operates on a wide range of media, data links and existing protocols like PJDL, PJDLR, PJDLS, Serial, RS485, USB, ASK/FSK, LoRa, UDP, TCP, MQTT and ESPNOW. PJON is an experimental network protocol stack crafted in 10 years of research and experimentation. It was originally developed as an open-source alternative to i2c and 1-Wire but during development, its scope and features have been extended to cover use cases where IP is generally applied. PJON has been engineered to have a variable footprint (4.2-8.2 kB program memory) and overhead (5-35 bytes per packet) depending on its configuration.

Multi-Modal Database replacing MongoDB, Neo4J, and Elastic with 1 faster ACID solution, with NetworkX and Pandas interfaces, and bindings for C 99, C++ 17, Python 3, Java, GoLang.

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.

A light weight configuration library for C++11.

C/C++ language server supporting multi-million line code base, powered by libclang. Emacs, Vim, VSCode, and others with language server protocol support. Cross-references, completion, diagnostics, semantic highlighting, and more. cquery is a highly-scalable, low-latency language server for C/C++/Objective-C. It is tested and designed for large codebases like Chromium. cquery provides accurate and fast semantic analysis without interrupting workflow. cquery implements almost the entire language server protocol and provides some extra features to boot. cquery is able to respond to queries quickly because it caches a huge amount of information. When a request comes in, cquery just looks it up in the cache without running many computations. As a result, there's a large memory overhead. For example, a full index of Chrome will take about 10gb of memory. If you exclude v8, webkit, and third_party, it goes down to about 6.5gb.

The magic that takes the pain out of accessing JSON API's from C++. It formulates a HTTP request to a REST API server. Then, it transforms the JSON formatted payload in the reply into a native C++ object (GET). It Serializes a native C++ object or a container of C++ objects into a JSON payload and sends it to the REST API server (POST, PUT). It formulates an HTTP request to the REST API without serializing any data in either direction (typically DELETE). It uploads a stream of data, like a file, to an HTTP server. It downloads a stream of data, like a file or an array of JSON objects, from a HTTP server.
