    SWIG

    SWIG

    A code generator for connecting C/C++ with other programming languages

    SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level programming languages. SWIG is used with different types of target languages including common scripting languages such as Javascript, Perl, PHP, Python, Tcl and Ruby. The list of supported languages also includes non-scripting languages such as C#, D, Go language, Java, Lua, OCaml, Octave, R and Scilab as well as the Guile implementation of the Scheme language. SWIG is most commonly used to create high-level interpreted or compiled programming environments, user interfaces, and as a tool for testing and prototyping C/C++ software. SWIG is typically used to parse C/C++ interfaces and generate the 'glue code' required for the above target languages to call into the C/C++ code. SWIG can also export its parse tree in the form of XML.

    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.

    GnuCOBOL

    GnuCOBOL

    A free COBOL compiler

    GnuCOBOL (formerly OpenCOBOL) is a free, modern COBOL compiler. GnuCOBOL implements a substantial part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards (2002, 2014, 2023), as well as many extensions included in other COBOL compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others). GnuCOBOL translates COBOL into C and internally compiles the translated code using a native C compiler. Build COBOL programs on various platforms, including GNU/Linux, Unix, Mac OS X, and Microsoft Windows. GnuCOBOL has also been built on HP/UX, z/OS, SPARC, RS6000, AS/400, along with other combinations of machines and operating systems. Copyright 2001-2024 Free Software Foundation, Inc.

    JD-GUI

    JD-GUI

    A standalone Java Decompiler GUI

    JD-GUI is a standalone graphical Java decompiler that allows users to reconstruct and explore source code from compiled .class files. It provides an intuitive interface for browsing decompiled code, making it easier to inspect methods, fields, and class structures without access to original source files. The tool is widely used for reverse engineering, debugging, and understanding third-party libraries. It supports opening individual files as well as entire archives such as JARs, enabling efficient navigation across large codebases. JD-GUI emphasizes simplicity and accessibility, allowing developers to quickly analyze compiled Java applications. It integrates with standard Java tooling and can be extended with additional modules. Overall, it is a practical utility for developers working with bytecode-level artifacts.

    GHDL

    GHDL

    VHDL 2008/93/87 simulator

    This directory contains the sources of GHDL, the open-source analyzer, compiler, simulator and (experimental) synthesizer for VHDL, a Hardware Description Language (HDL). GHDL is not an interpreter: it allows you to analyze and elaborate sources for generating machine code from your design. Native program execution is the only way for high-speed simulation. Full support for the 1987, 1993, 2002 versions of the IEEE 1076 VHDL standard, and partial for the 2008 and 2019 revisions. By using a code generator (LLVM, GCC or, x86_64/i386 only, a built-in one), it is much faster than any interpreted simulator. It can handle very large designs, such as leon3/grlib. GHDL runs on GNU/Linux, Windows and macOS; on x86, x86_64, armv6/armv7/aarch32, aarch64 and ppc64. You can freely download nightly assets, use OCI images (aka Docker/Podman containers), or try building it on your own machine.

    Ccache

    Ccache

    A fast compiler cache

    Ccache is a compiler cache. It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. Ccache is free software, released under the GNU General Public License version 3 or later. Supports GCC, Clang, MSVC (Microsoft Visual C++) and other similar compilers. Works on Linux, macOS, other Unix-like operating systems and Windows. Understands C, C++, assembler, CUDA, Objective-C and Objective-C++. Supports secondary storage over HTTP (e.g. using Nginx or Google Cloud Storage), Redis or local filesystem, optionally sharding data onto a server cluster. Supports fast "direct" and "depend" modes that don't rely on using the preprocessor. Supports compression using Zstandard. Checksums cache content using XXH3 to detect data corruption. Keeps statistics on hits/misses. Automatic cache size management. Easy installation.
