    DockPanel Suite

    DockPanel Suite

    The Visual Studio inspired docking library for .NET WinForms

    Microsoft first introduced the docking panel layout in Visual Studio .NET (2002), and soon it became popular in application design. Many commercial .NET component vendors started to provide docking libraries initially, but there was no good free and open source alternative until WeiFen Luo released DockPanel Suite (DPS for short) on SourceForge.net in 2006. After an 18 month hiatus, the project has been resurrected and is now being actively developed on GitHub.

    WebP Codec

    WebP Codec

    Library to encode and decode images in WebP format

    ...It supplies cwebp to compress images into WebP and dwebp to decompress them back, making it easy to test quality/size trade-offs across presets and tuning parameters. The GitHub repository is a mirror; the canonical source of truth lives on Chromium’s git, and developer docs are hosted on WebP’s portal. The project underpins WebP support across browsers, imaging libraries, and many native apps thanks to its stable C API. Additional companion repos host test data and demos, including JavaScript builds and timing tests for various platforms. As a widely deployed codec, libwebp balances compression efficiency, speed, and integration simplicity across platforms.

    luaposix

    luaposix

    Lua bindings for POSIX APIs

    This is a POSIX binding for LuaJIT, Lua 5.1, 5.2, 5.3 and 5.4; like most libraries, it simply binds to C APIs on the underlying system, so it won't work on non-POSIX systems. However, it does try to detect the level of POSIX conformance of the underlying system and bind only available APIs. For a while, luaposix contained support for curses functionality too, but now that has its own lcurses repository again, where it is being maintained separately.

    Particle Firmware for the Electron, P1

    Device OS (Firmware) for particle devices

    The Photon uses an ARM Cortex M3 CPU based microcontroller. All of the code is built around the GNU GCC toolchain offered and maintained by ARM. The build requires version 5.3.1 20160307 or newer of ARM GCC and will print an error message if the version is older than this. In order to turn your source code into binaries, you will need a tool called make. Windows users need to explicitly install make on their machines.

    Library to use Kotlin Coroutines from Swift code in KMP apps

    A library to use Kotlin Coroutines from Swift code in KMP apps. Both KMP and Kotlin Coroutines are amazing, but together they have some limitations. The most important limitation is cancellation support. Kotlin suspend functions are exposed to Swift as functions with a completion handler. This allows you to easily use them from your Swift code, but it doesn't support cancellation. Besides cancellation support, ObjC doesn't support generics on protocols. The library consists of a Kotlin and...
