Pattern Language

The Pattern Language is the completely custom programming language developed for ImHex. It allows you to define structures and data types in a C-like syntax and then use them to parse and highlight a file's content.

Database

For format patterns, libraries, magic and constant files, check out the ImHex-Patterns repository.

Feel free to PR your own files there as well!

Requirements

To use ImHex, the following minimal system requirements need to be met.

[!IMPORTANT] ImHex requires a GPU with OpenGL 3.0 support in general. There are releases available (with the -NoGPU suffix) that are software rendered and don't require a GPU, however these can be a lot slower than the GPU accelerated versions.

If possible at all, make ImHex use the dedicated GPU on your system instead of the integrated one (especially Intel HD GPUs are known to cause issues).

Installing

Information on how to install ImHex can be found in the Install guide

Compiling

To compile ImHex on any platform, GCC (or Clang) is required with a version that supports C++23 or higher. On macOS, Clang is also required to compile some ObjC code. All releases are being built using latest available GCC.

[!NOTE] Many dependencies are bundled into the repository using submodules so make sure to clone it using the --recurse-submodules option. All dependencies that aren't bundled, can be installed using the dependency installer scripts found in the /dist folder.

For more information, check out the Compiling guide.
