    ILSpy

    ILSpy

    .NET Decompiler with support for PDB generation, ReadyToRun, Metadata

    ILSpy is the open-source .NET assembly browser and decompiler. Visual Studio 2022 ships with decompilation support for F12 enabled by default (using our engine v7.1). In Visual Studio 2019, you have to manually enable F12 support. Go to Tools / Options / Text Editor / C# / Advanced and check Enable navigation to decompiled source. C# for Visual Studio Code ships with decompilation support as well. To enable, activate the setting "Enable Decompilation Support. ILSpy is distributed under the MIT License. Please see the About doc for details, as well as third-party notices for included open-source libraries. Visual Studio 16.3 and later include a version of the .NET (Core) SDK that is managed by the Visual Studio installer - once you update, it may get upgraded too. Please note that ILSpy is only compatible with the .NET 6.0 SDK and Visual Studio will refuse to load some projects in the solution.

    unluac

    A decompiler for Lua 5.x

    unluac is a decompiler for Lua 5.0 through 5.4. It runs on Lua chunks that have been compiled with the standard Lua compiler. It requires that debugging information has not been stripped from the chunk. (By default, the Lua compiler includes this debugging information.) This program is written in Java. A JAR package is available in the downloads section so you don't have to compile it. It runs from the command line and accepts a single argument: the file name of a Lua chunk. The decompiled code is printed to the standard output. Here is an example usage of unluac: java -jar unluac.jar myfile.lua > myfile_decompiled.lua The current version also has pretty good support for Lua 5.0 and Lua 5.1. Support for later versions is also good if the code doesn't use too many gotos.

    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.

    4tH compiler

    4tH compiler

    A Forth compiler with a little difference

    4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, BASIC interpreter, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

    NullsoftDecompiler

    Decompiler for setups creates with the Nullsoft Installer

    Python scripts that'll help you to nearly fully recover your NSIS-installation scripts. It's currently in the 'alpha-state' however it's not far from being worth to title as beta or release. I'm new to Sourceforge - for small updates I may also prefer the page below. UPDATE: It'll maybe not working on this anymore. http://7-zip.de does a great job in also decompiling NSI.So I recommand you to check out 7-zip BETA. Generally 7-zip opens NSI[exe] files - since 9.33 [2014-06-15] there should be additionally the file [NSIS].nsi inside, that is the decompiled setup script. Attention this NSIS decompilation was disabled in 7z 15.06. So last version that officially **supports NSIS Script decompilation** is 7z **15.05** https://sourceforge.net/projects/sevenzip/files/7-Zip/15.05/ (2015-06-15) -> 7-zip 15.10 no longer decompiles NSIS script http://bit.do/7zNoMoreNSIS ^-however doing a private build you may get it back(more details in the post).
