    reko

    reko

    Reko is a binary decompiler

    Reko (Swedish: "decent, obliging") is a decompiler for machine code binaries. This project is freely available under the GNU General Public License. The project consists of front ends, core decompiler engine, and back ends to help it achieve its goals. A command line, a Windows GUI, and a ASP.NET front end exist at the time of writing. The decompiler engine receives inputs from the front ends in the form of either individual executable files or decompiler project files. Reko project files contain additional information about a binary file, helpful to the decompilation process or for formatting the output. The decompiler engine then proceeds to analyze the input binary. Reko has the ambition of supporting decompilation of various processor architectures and executable file formats with minimal user intervention. For a complete list, see the supported binaries page.

    XSharpDev

    XSharp Repository for the Compiler source code

    The Roslyn folder contains (modified) source from Roslyn The XSharp folder contains our own source for the compiler, documentation and other components. For the build process of the compiler we create our own "specialized" version of the CSharp Compiler. The source for this compiler and codeanalysis.dll is in the Tools folder. This compiler will translate some of the Roslyn Namespaces from CSharp into XSharp to prevent name conflicts when assemblies of both origins are in memory at the same time. Make sure you have VS 2019 or 2017 installed. The preferred edition is Enterprise. Make sure you have Java JDK on your machine and that you have the Java binaries folder in your Path. If you do not have Vs 2019 Enterprise you can set 2 environment variables to the VS version and edition you have installed.
