    Proxy

    Proxy

    Proxy: Next Generation Polymorphism in C++

    For decades, object-based virtual tables have been a de facto implementation of runtime polymorphism in many (compiled) programming languages. There are many drawbacks in this mechanism, including life management (because each object may have a different size and ownership) and reflection (because it is hard to balance between usability and memory allocation). To workaround these drawbacks, some languages like Java or C# choose to sacrifice performance by introducing GC to facilitate lifetime management, and JIT-compile the source code at runtime to generate full metadata. We improved the theory and implemented it as a C++ library without sacrificing performance, proposing to merge it into the C++ standard.

    Simple-Web-Server

    Simple-Web-Server

    A very simple, fast, multithreaded, platform independent HTTP and HTTP

    A very simple, fast, multithreaded, platform-independent HTTP and HTTPS server and client library implemented using C++11 and Asio (both Boost.Asio and standalone Asio can be used). Created to be an easy way to make REST resources available from C++ applications. See particularly the JSON-POST (using Boost.PropertyTree) and the GET /match/[number] examples, which are most relevant. Before running the server, an RSA private key (server.key) and an SSL certificate (server.crt) must be created. Timeouts, if any of Server::timeout_request and Server::timeout_content are >0 (default: Server::timeout_request=5 seconds, and Server::timeout_content=300 seconds). Simple way to add REST resources using regex for path, and anonymous functions.

    Task Scheduler

    Task Scheduler

    Cooperative multitasking for Arduino, ESPx, STM32, nRF and more

    Cooperative multitasking for Arduino, ESPx, STM32 and other microcontrollers. A lightweight implementation of cooperative multitasking (task scheduling). An easier alternative to preemptive programming and frameworks like FreeRTOS. You mostly do not need to worry about pitfalls of concurrent processing (races, deadlocks, livelocks, resource sharing, etc.). The fact of cooperative processing takes care of such issues by design.

    easy_profiler

    easy_profiler

    Lightweight profiler library for c++

    Lightweight cross-platform profiler library for C++. You can profile any function in your code. Furthermore, this library provides measuring time of any block of code. For example, information for 12 millions of blocks is using less than 300Mb of memory. Working profiler slows your application execution for only 1-2%. The average overhead per block is about 15ns/block (tested on Intel Core i7-5930K 3.5GHz, Win7). Disabled profiler will not affect your application execution in any way. You can leave it in your Release build and enable it at run-time at any moment during the application launch to see what is happening at the moment. Also, the library can capture the system's context switch events between threads. Context switch information includes duration, target thread ID, thread owner process ID, and thread owner process name. You can see the results of measuring in a simple GUI application which provides full statistics and renders a beautiful time-line.

    libgphoto2

    libgphoto2

    The libgphoto2 camera access and control library

    libgphoto2 is a library that can be used by applications to access various digital cameras. libgphoto2 itself is not a GUI application, as opposed to gphoto. There are GUI frontends for the gphoto2 library, however, such as gtkam for example. libgphoto2 can only talk to cameras the language of those it understands. That is, if you own a camera that speaks a language that isn't published anywhere and nobody has been able to figure out the meaning of the sentences, libgphoto2 cannot communicate with those cameras. Then, there are cameras supporting the so-called USB Mass Storage protocol. This is a protocol that has been published and lets you access any storage device, be it a camera or a disk connected via USB to your computer. As there are already drivers for this protocol out there, you don't need an additional library like libgphoto2. The list of cameras that use USB Mass Storage is getting longer every day, so we won't publish it.

    wxPHP

    wxPHP

    PHP bindings for the cross-platform GUI library wxWidgets.

    wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it.

    Sudoku Game Solver Generator

    Sudoku Game Solver Generator

    Standalone Complete Sudoku puzzle Game Solver Generator for Windows

    This is the most complete and standalone Sudoku puzzle suite for Windows. It includes comfort playing with undo steps and powerful Sudoku generator with different difficulty levels. Also you can create Sudoku game manually and print it on an A4/Letter paper. Tutorial mode with solving hints for newbies is included too. Also there is High Score table and built-in timer for professional players. The Sudoku generation algorithm used by this app is my ultimate proud. Primarily it was based on a Deep Neural Network. But I analyzed more than 100 scientific publications on Sudoku generation problem and have reduced the Deep Neural Network to a relatively simple and very elegant deterministic algorithm that works pretty fast. As a result, the app can generate Sudoku fields in 7 difficulty levels from 'Yellow Belt' to 'Sudoku Game Jedi Master'. The application supports Quick Start mode, see features below [QS Step 1] and [QS Step 2] (buttons in an application window).

    soulng

    Lexer and parser generator tool for C++

    The SoulNG project contains two tools: a lexical analyzer generator slg and a parser generator spg. The generators and the produced lexical analyzers and parsers use four C++ libraries that are also included in the project. The slg tool takes a .lexer file that contains the description of a lexical analyzer as input and produces C++ source code for a lexical analyzer as output. The produced lexical analyzer is a finite state machine that recognizes patterns described as regular expressions and return corresponding token identifiers to the parser. The spg tool takes .parser files that contain descriptions of parsers as input and produces C++ source code for parser classes as output. The parser generator produces a recursive descent top-down backtracking parser that use the lexical analyzer generated by slg to tokenize the input.

    Lib CONIO (conio_am.h) GCC C++

    Lib CONIO (conio_am.h) GCC C++

    Library CONIO GCC C++ for Windows e Linux (POSIX)

    New version 7.1.22.12 - prealpha. This project presents clone of the Borland Turbo C/C++ or Embarcadero C++ library "conio" for the GCC compiler, more precisely for the C++ language in Windows, Linux and Mac OS operating systems. Because all functions are defined within the header file itself, the installation is simple. Just place the header file "conio_am.h" (CONsole Input Output Advanced Method) inside the GCC includes directory. Or keep the file "conio_am.h" in the same location where the source programs will be compiled. For more libraries, go to: https://sourceforge.net/u/augustomanzano/profile.
