    Notepad++ Plugin Manager

    Notepad++ Plugin Manager

    The nppPluginManager repository contains the legacy Plugin Manager for Notepad++, a tool that once allowed users to easily install, update, and remove plugins within the editor. It relied on a centrally hosted XML file that listed available plugins, which the manager compared against those already installed. Since 2019, however, the plugin is no longer actively maintained, and the supporting web service that provided plugin lists has been discontinued. Users are now encouraged to rely on Notepad++’s built-in plugin solution instead of this deprecated tool. This project is the old location for the plugin list for Notepad++ Plugin Manager. Please use https://github.com/bruderstein/npppluginmanager for any issues and current code

    SWIG

    SWIG

    A code generator for connecting C/C++ with other programming languages

    SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of target languages including common scripting languages such as Javascript, Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, D, Go language, Java, Lua, OCaml, Octave, R and Scilab as well as the Guile implementation of the Scheme language. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code. SWIG can also export its parse tree in the form of XML.

    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

    Turbo C++

    Turbo C++

    Turbo C++ for Latest Edition of Windows

    TurboCPP is a repository that presents a version of the classic Turbo C++ IDE made compatible with modern Windows editions (Windows 8, 10, 11). Essentially, it revives a legacy development environment that many students or enthusiasts still prefer for simplicity or nostalgia, packaged for current systems. The repository includes installer or distribution artifacts, compatibility wrappers, and sometimes tweaks to make it work under modern OS constraints. It allows users to run and compile old Turbo C++ programs without needing legacy virtual machines or DOS emulators. While it does not match modern compilers in standards compliance, optimization, or language features, its attraction lies in compatibility with educational or legacy codebases. The project targets hobbyists or learners who want to revisit old C++ assignments or retro programming without abandoning newer system environments.

    Notepad++

    Notepad++

    Free, open-source text editor

    Notepad++ is a source code editor that is free to use and is available in various languages. The source code editor is also written in C++ and is based on the Scintilla editing component. Notepad++ offers a wide range of features, such as autosaving, line bookmarking, simultaneous editing, tabbed document interface, and many more features. Over 140 plugins are also available to use in the default program. Notepad++ takes advantage of higher execution speed and smaller program size by using Win32 API and STL. The ability to optimize efficiency without sacrificing user-friendliness results in an environment-friendly technology that reduces carbon dioxide emissions. Ultimately, the reduction in power consumption is much better for the environment while still being a viable option for businesses.
