    SWC

    SWC

    Rust-based platform for the Web

    SWC is an extensible Rust-based platform for the next generation of fast developer tools. It's used by tools like Next.js, Parcel, and Deno, as well as companies like Vercel, ByteDance, Tencent, Shopify, and more. SWC can be used for both compilation and bundling. For compilation, it takes JavaScript / TypeScript files using modern JavaScript features and outputs valid code that is supported by all major browsers. SWC is 20x faster than Babel on a single thread and 70x faster on four cores. SWC can be downloaded and used as a pre-built binary, or built from the source. SWC (stands for Speedy Web Compiler) is a super-fast TypeScript / JavaScript compiler written in Rust. It's a library for Rust and JavaScript at the same time. If you are using SWC from Rust, see rustdoc and for most users, your entry point for using the library will be parser. If you are using SWC from JavaScript, please refer to the docs on the website.

    WinCC Open Architecture C# Framework

    C# Framework for WinCC OA Open Architecture connectivity (XMLRPC)

    Author: Andreas Vogler Homepage: www.rocworks.at Communication .Net client to WinCC Open Architecture. Works fine with MonoTouch and Mono for Android! GPLv3 License is used for the public domain. If you plan to use it in a CLOSED SOURCE project, please get in touch with me - andres.vogler@gmail.com ! Communication can be done directly with XMLRPC or with the included proxy: * .net remoting is used for "commands" from the client to the proxy (dpConnect, dpQueryConnect). * tcp (xml over tcp) for sending unsolicited data/events from the proxy to the client. The proxy also acts as a distributor - if clients have the same dp(Query)Connects, the connects are done once, and the proxy will forward it to the clients. Easy example for a dpQueryConnect with a delegate: client.DpQueryConnectSingle((object s, ArrayList a) => { Console.WriteLine("event!); }, "SELECT '_online.._value', '_online.._stime' FROM '*.**'");
