    Handlebars.Net

    Handlebars.Net

    A real .NET Handlebars engine

    Handlebars.js is an extension to the Mustache templating language created by Chris Wanstrath. Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be. Handlebars.Net doesn't use a scripting engine to run a Javascript library - it compiles Handlebars templates directly to IL bytecode. It also mimics the JS library's API as closely as possible. Blistering-fast Handlebars.js templates in your .NET application.

    IDA#Plug

    A Visual Studio integrated framework for C# plugins targeting IDA Pro

    IDA from Hex-Rays SA is a well-known dis-assembly software extensively used in the reverse engineering field. IDA provides an extensive API for C language plugin development. While efficient, C can be painful and time consuming as soon as you attempt to develop high level tasks. This project attempts to provide : - A framework that let you develop plugins using C# - Visual Studio integration for ease of use Plugins are mixed mode libraries (managed+unmanaged) relying on a .Net library wrapping the native API. Using a wrapping layer, performances are expected to be poorer than those from the native API. Consequently this project shouldn't be considered a catch all replacement for the existing native API. The project is in early development stage. See project wiki for milestones and completion points. Disclaimer : This project is neither backed nor supported by Hex-Rays SA.

    ImageProcessor

    ImageProcessor

    Wrapper around System.Drawing for the processing of image files

    A .NET library for on-the-fly processing of images. ImageProcessor is a collection of lightweight libraries written in C# that allows you to manipulate images on-the-fly using .NET 4.5+. It consists of two main libraries ImageProcessor, for desktop and application use and ImageProcessor.Web, a dynamic image processing extension built for ASP.NET. It’s lighting fast, extensible, easy to use, comes bundled with some great features and is fully open source. ImageProcessor is free and open source but developing it has taken thousands of hours of my time and a large part of my sanity. If you feel like dropping me a few precious pounds (there’s no obligation) it would go a great way to ensure that I can afford to take the time to continue to improve the library. It's fast, extensible, easy to use, comes bundled with some great features and is fully open source.
